Renewable energies already meet a fifth of all energy requirements around the world today. According to the London-based financial information service, Bloomberg New Energy Finance, global investments for this market will amount to over 630 billion US dollars by 2030. Germany’s “Energiewende” (energy transition) is seen as a postulate far beyond the borders of Europe. Countries that benefited from the oil boom of the past century are now making the decision to carry out research into renewable energies. It would appear that a paradigm shift is occurring. However, the rapidly growing world population’s appetite for energy must be stilled by sustainable means. Conventional power plants cannot be shut down from one day to the next. Every week, two new coal-fired power plants begin operation in China. And India finds itself venturing towards gigantic nuclear power plants on the one hand and alternative energies in rural areas on the other. Our title story shows how decentralized supply systems usher in the future in these regions. In another article, we reveal how a regional town supply system can serve as a model for large industrial sites. In this issue we would like to present you, dear readers, with reliable and efficient solutions that make one thing clear: renewable energy is unquestionably on the rise; sustainability is the motto – penetrating deep into the corporate culture of global companies. This is true at REHAU, too. At the mention of “energy transition”, most of us think of solar plants and wind farms, or maybe even alternative mobility concepts, but few are reminded of the plastics industry. We hope you enjoy discovering how REHAU’s intelligent systems solutions help pave the way to an age of renewable energy and energy efficiency. Enjoy the read!

In an effort to prevent the imminent spread of drylands and curb the rise of China’s greenhouse gas emissions, the Jane Goodall Institute intends to have planted one million trees in the desert of Mongolia by 2014. The tree-planting initiative aims to make people aware of how important and easy it is to counter ever-increasing environmental pollution. The institute, named after the famous British primatologist and conservationist, is a recognized non-governmental organization and China’s first and only foreign environmental protection organization. www.rootsandshoots.org 06/13 _ REHAU unlimited 05 REHAU _ News 02 Automotive industry 04 Sustainability Hydrogen – The Future Bhutan wants to produce only organic food in future.

And many of them are also crazy about football. Denmark means business: since the beginning of 2013, new buildings may no longer contain boilers fuelled by oil or natural gas. Starting in 2016, the Scandinavian country will take it even further and ban the renewal of oil heating systems in existing buildings – at least for those that can connect to the public district heating grid or convert to natural gas heaters. Now imagine a football that generates and stores energy while it’s being kicked around. This brilliant idea has now become reality. Just 30 minutes of play with this ball is enough to power an LED lamp – which can be directly connected to the ball – for three hours. The high-tech ball, “Soccket”, was developed by Harvard University students.

Large-scale nuclear and solar projects aim to ensure economic growth. In rural areas, attempts are being made to use renewable energy to strengthen the infrastructure. here, in front of the entrance to Muni Seva ashram, about 40 kilometers from Vadodara airport, things look bleak. India has a waste problem, especially in rural areas. The towering mountains of rubbish along the roadside are visible to everyone. across the road looking for food is a donkey, which is not the norm; the people who live here prefer cows as pets. On the main road is a small settlement which supplies visitors to the ashram with products they can’t buy inside. The stores are often simple corrugated-iron shacks, whose entrances have been transformed into puddles of mud by the monsoon rains. Muni Seva Ashram: a different world, clean and perfect. Deepak Gadhia with the ashram’s director, Vikram Patel. In the ashram, a kind of hindu monastery where people live long term in order to grow and develop (spiritually), one finds oneself in quite a different, clean and undamaged world. Catching one’s eye at the entrance are 100 large parabolic mirrors. The tarred roads on the grounds are immaculate and swept daily by hand. The buildings, up to Western standards, are of solid brick and have round-the-clock electricity, air conditioning and sanitation facilities supplying clean water. The entire area is landscaped; various species of trees and plants provide shade and in the meadow, exuberant children play. “We currently generate 30 percent of our energy needs ourselves; by 2014, we want to reach 100 percent.” Deepak Gadhia is fluent in German.

Renewable energy* 22,233 MW Coal 105,437 MW Hydropower 38,848 MW * incl. hydroelectric power stations with capacities up to 25 GW It all began in 1980 when the founder, anuben Thakkar, was prompted into action by her guru’s afflatus; trying to create a kind of Indian model village, she built her house on what is the site of today’s ashram. “It is estimated that 80,000 Indian villages have massive energy and water supply problems,” says Gadhia. “Muni Seva aims to show that there are also decentralized solutions for regions with poor infrastructure.” The ashram sets the highest standards in terms of comprehensiveness and sustainability – and not just by Indian standards, either. energy supply, energy recovery, resource conservation are now at a level which, on the one hand is adapted to local requirements, but on the other, holds its own on the international stage. From the solar cooker designed for individual households to the solar installations for the operation of schools and hospitals, from the photovoltaic lamp to the comprehensive lighting and ventilation systems, solar-powered water treatment and wood gasification systems: Muni Seva is literally a microcosm for renewable energy applications. as early as 1984, the uchchatar uttar Buniyadi Vidyalaya School became the proud owner of a solar-powered system, which supplied energy to the school’s canteen. It was, according to Gadhia, “probably the first solar installation in an Indian school.” The Source: Ministry of Power India, gtai, 2012 and Management at the Technical university of Berlin “right in the middle of the green movement,” as he says himself. Gadhia is on the board of the Muni Seva Trust, a donation-funded foundation and the nerve center of the community. In 2011, after the death of his wife, he sold his solar technology company and dedicated his life and abilities entirely to the ashram. Gadhia recalls his first years as a sales rep for a German solar equipment manufacturer in the mid ’80s. at that time, the Indian energy market was a purely local affair; only after laborious negotiations with the Indian authorities did the engineer manage to sell his first solar energy system in his home country. Deals in Malaysia and Indonesia followed, but Gadhia’s ambitions lay elsewhere: his dream was to bring his know-how to his home country. idea of sustainability and the principles of renewable energy generation are taught both theoretically and practically in the ashram’s three schools. In the dormitories and study areas, photovoltaic batteries supply LeD lamps and fans day and night. If the children forget to switch off the lights when leaving a room, it might happen that there’s no light and ventilation during night-time hours. “This way, the children learn to save the existing resources and use them efficiently in future,” says Gadhia. For the most part, cooking is powered by solar energy. India has on average 300 days of sunshine – optimal conditions. however, since the cooking equipment only works with direct sunlight, there is an alternative method: wood gasification. This process requires approximately 70 percent less wood; plus, in contrast to an open fire, the cooker can be regulated. The central idea at Muni Seva is to create a cycle in which both man and nature chime together. here in particular, biogas plants play a major role. If in the past the massive piles of cow dung created a hygiene problem, today biogas plants provide an all-in-one solution. The dung is collected, mixed with hay and filled into tanks where it is turned into clean biogas and used for cooking, as a fuel for vehicles, to cool the ashram’s in-house infirmary, and to power the generators which produce electricity. The by-product – organic fertilizer – is used for farming. It’s a twobird-one-stone scenario: plant waste is being converted into energy in tanks and sanitation and waste disposal is being improved. 06/13 _ REHAU unlimited 13 REHAU _ Renewable energies World’s top investors in renewable energy in 2012: China 65,10 U.S. 35,60 Germany 22,80 Other EU-27 16,30 Japan 16,30 Italy 14,70 UK 8,30 India 6,90 South Africa 5,50 Brazil 5,30 Investments in billion US dollars Source: Bloomberg 2013 Furthermore, the harmful smoke caused by burning wood or oil is eliminated. The same is true for the generation of light through photovoltaics: it replaces the smoke-intensive kerosene lamps. Muni Seva is trying to promote these kinds of approaches in the surrounding villages. Interest-free, installment payment plans are offered in an effort to make these options affordable, since propane and keroIndia swaying between subsidized green energy and conventional power plants. sene are ridiculously cheap. Gadhia: “So far, only one in every thousand Indians cooks with electricity, one in two with wood, one in three with propane gas. The rest use diesel or kerosene.” The generation of renewable energy in India has a comparatively long history: the establishment of the Ministry of New and Renewable energy (MNRe) dates back to 1992; nevertheless, the progress made in the interim has been negligible. In the first half of 2013, just 12 gigawatts of electricity – from a total annual demand of around 210 gigawatts – were generated from renewa- 14 Rehau unlimited _ 06/13 Biogas supplies energy for cooking. ble energy sources. But this does not deter Gadhia from arguing in favor of renewable energy production. “The construction of large plants is initially expensive, but will pay itself off within a few years.” according to Gadhia, solar collectors covering a mere two percent of the total area would completely meet India’s current energy needs. energy has become a political issue in India. The dependence on the international oil market in particular has prodded the government into providing extensive subsidy measures. Wind energy is a rapidly growing market, already generating approximately eleven gigawatts per year; photovoltaics produce almost 1 gigawatt. and now the Rajasthan desert is set to play host to the largest solar power plant in the world. The plant aims to achieve a peak power of 4,000 megawatts, which is equivalent to three large nuclear power plants. how much the megaproject will cost is still unclear, but one thing is certain: The goal is to become the largest producer of solar energy in the world by 2020 and increase the country’s share of renewable energies to 22 percent. Following the German example, green electricity is subsidized through extra charges per kilowatt hour. REHAU _ Renewable energies REHAU’s contribution: Generating almost 30 percent of its own electricity needs, Muni Seva Ashram is home to an array of modern technology. At the heart of this is the biogas plant connected to a combined heating and power plant. REHAU delivered the key components of this system, which is slowly but surely gaining ground in India. Decentralized plants like this efficiently supply energy where it is needed the most: to people in rural areas. RAUBIO – Digester Heating System Biogas is recovered through the fermentation of organic matter in an airtight and light-tight digester. The fermentation processes require temperatures between 40 °C and 50 °C. The digester heating system RAUBIO Fix is a special PE-Xa heating system, which is easy to install and which guarantees that the digester is heated effectively. It is highly resistant to acid, temperature and pressure, and installation is connectionless. The material even prevents microbiological corrosion. School life: theory with a foundation in reality. But the government has set its sights on other energy avenues, too. Currently, it’s planning to build the largest nuclear power plant in the world – 800 kilometers south of the ashram. It’s expected to generate ten gigawatts per year. By 2030, the overall output of Indian nuclear power plants is projected to increase from its current level of five gigawatts to an impressive 64. Whether that will be enough to meet the growing energy needs of the subcontinent remains questionable. “The problem in India is not that we’re producing too little energy,” says Gadhia. “It’s that it’s not distributed fairly.” emerging economic centers such as Mumbai or Bangalore are well looked after. although there are also functioning power supply networks out in the country, they remain unaffordable for the rural population. In Gadhia’s view, only needs-based, renewable energy generation sources will allow people to help themselves and gain independence from the state energy market and its fluctuating prices. But: “The only thing that doesn’t work in India is logic: If you begin to ask ‘Why?’ then you’ll go crazy,” he says, laughing. < RAUBIO – Gas condensate collection chamber The recovered biogas cools down during transportation from the digester to the combined heating and power plant. The RAUBIO gas condensate collection chamber collects the water condensate from the gas stream and discharges it safely and reliably at the lowest point of the gas pipe. REHAU is the first company to manufacture an industrial standard solution for condensate separation in biogas plants.

They’re creating heat and electricity out of waste. REHAU _ On Site The town in numbers Population 9,374 Area 80.34 km² Population density 117 inhabitants/km² Country Germany State Bavaria Administrative region Upper Franconia Geographic location 50° 15’ N, 12° 2’ E Local companies approx. 700 companies (mainly plastic, ceramic, leather, textile, metal and wood industry) is largely based on renewable energy. In essence, the idea is simple: to generate heat and electricity from industrial waste. as a technology expert, energy Solutions Gmbh specializes in just such projects. In collaboration with the tannery Südleder, the company is tackling what renowned universities up until recently still thought impossible: the generation of biogas from tannery Goal: a decentralized energy supply mosaic based on renewable energy. High-tech out in the country: huge digester silos. Family homes, shops and traditional market life amid vegetables, spices and pastries: at first glance, the Bavarian town of Rehau looks pretty run-of-the-mill. Rural idyll instead of big-city bustle. But unlike most other municipalities in Bavaria, this 10,000-inhabitant town is characterized by strong industrial growth. Old brick buildings and factory halls recall the town’s historical roots in porcelain and leather processing, which date back to the 19 th century. Today, Rehau is home to the largest tannery in Germany, europe’s largest site for the production of stone tiles and the eponymous global plastics company. Comprising around 700 companies, the town is considered an industry stronghold. With its energy consumption of 70 million kilowatt hours per year, it consumes several times more energy than other small towns with comparable populations. Rehau: run-of-the-mill? anything but. The same is true for its industrial enterprises: With their eco-conscious ambition and mid-size company innovative drive, they are paving the way for the future. The expressed goal is to successively establish a decentralized energy supply system, which waste. Located in Rehau, Südleder is a tannery company with a long-standing history. every year, it produces over five million square meters of high-quality leather for the automotive and furniture industries. “The production creates waste, which is rich in organic ingredients and which, due to its special composition, had to be disposed of by expensive means,” said eric Priller, CeO of energy Solutions. “So, the idea was, could energy be generated from this waste?” In other words: Let’s make a virtue out of necessity. Construction of a plant to recover fat from glue stock began in 2007. Fat acts as a replacement for fossil fuels. Five years later, a unique process is setting new standards. By developing a fermentation method which produces biogas from the organic ingredients of process water and the waste material from the fatrecovery process, energy Solutions was able to cut in half the amount of tannery waste to be disposed of in 2012. Since then, the amount of electricity and heat generated has made Südleder virtually energy self-sufficient. With this result, energy Solutions can boast not only to have refuted published reports, but also to have revolutionized to some extent the entire waste management market. “We’re proving that it’s technically and chemically possible to produce biogas from tannery waste,” said eric Priller proudly. his company, founded in 2010, is firmly establishing itself as a solutions provider for previously unimaginable challenges. 06/13 _ REHAU unlimited 17 Eric Priller, Director of Energy Solutions, in front of the Südleder biogas plant. Traditional market scene: wednesdays in the historic town center. 06/13 _ REHAU unlimited 19 REHAU _ On Site REHAU’s contribution: Defining townscape: industrial architecture. The bioenergy plant for the fermentation of industrial byproducts is just one element in the mosaic of Rehau’s decentralized energy supply system. In 2012, energy Solutions built a 400-kilowatt biogas plant in the district of Kühschwitz and this plant is connected to the municipal power grid. Businesses and 650 households draw their power from here. Via a district heating network, the plant also supplies other households and businesses with heat. Located in the village, the company Rehau has been operating a bio-methane combined heating and power plant since 2012. With a total capacity of almost one megawatt, it covers the Providing energy for businesses and citizens: Biogas, bioenergy plant and combined heating and power plants. electricity needs of all of the company’s administrative buildings and more than half of their heat requirements. any electricity produced in excess flows directly into the public network, which has recently been bolstered by another component: the second 630-kilowatt-hour combined heating and power plant belonging to the company Südleder. Together these three plants – the Südleder bioenergy plant, the biogas power plant and the combined heating and power plants – already cover over 25 percent of the energy needs of the town of Rehau today. Note: Wind and solar power are not part of picture. “a coverage rate of over a quarter is pretty decent for an industrial town,” says Priller. he reveals that more development stages are being targeted in order to further increase the share of renewable energies of the town’s total energy consumption. No question: cost-effectiveness, entrepreneurial instinct and comprehensive technical know-how go hand in hand in Rehau. Towards a clean future, where not only the enterprises participating in the free energy consortium benefit, but also the town itself and its inhabitants – the homeowner, the baker and the greengrocer. This is what’s run-of-the-mill in Rehau. < 20 Rehau unlimited _ 06/13 By founding Energy Solutions GmbH, REHAU chose to specialize early in the market and potential of renewable energies. In Rehau, Bavaria, the company’s achievements are making a huge difference. Here, neither wind nor solar power is relied upon; instead, energy is primarily derived from waste.The processes developed by Energy Solutions are designed for this and are already catching on around Europe: “TanERGY” Unique around the world, this process generates energy from waste. In Rehau, this waste is from the local tannery, 76 percent of which is turned into energy. Electricity and heat are recovered through fermentation processes. “WastERGY” With this newly developed process, the domestic waste bin takes center stage in the production of renewable energy. Municipal bio-waste could in future supply the nutrients for a fermentation concept that generates energy out of compost mountains. “NetERGY” A superordinate, self-learning control system could in future record and regulate all the parameters of a local self-supply system of energy derived from bio-waste. The system monitors the environmental influences – such as wind, sun and outdoor temperatures – as well as the behavior of energy producers and consumers.

For three years now, I’ve been involved with ‘Israel Connect’, an initiative that brings young people closer to the land of the Bible. So, not the typical tourist trail. We organize meet-up tours funded by donations and get together with interesting people all over the country. I enjoy planning and preparing the trips. That’s probably the analyst coming through in me. Or maybe the philanthrope.

For over 25 years Michel Moor has been working at IKea in Lausanne, Switzerland. and for over 25 years, as an environmental coordinator and sustainability manager, working both full- and part-time, he’s been dealing with issues such as a clean environment, renewable energy, and green economies. If anyone knows what “sustainability” means at IKea, then it’s him. It’s all the more surprising then that when asked when exactly IKea discovered sustainability, he has to think. ”I can tell you the dates, pas de problème. But actually, everything has always been there.” The notion of sustainability at IKea is probably as old as IKea itself. It probably began when the company’s founder, Ingvar Kamprad, insisted that no rainforest, no tree from a natural forest Logistics, design and production – nothing is left to chance. shall ever fall victim to one of his tables, chairs, shelves. and since Kamprad is well known for saying what he thinks and for doing what he says, to this day, not a single piece of teak can be found in any IKea product – no matter how trendy teak is today. IKea is structure as a culture. Wood structure, textile structure, distribution structure. and above all else: corporate structure. Nothing is left to chance here, especially not the issue of sustainability. “Want an example?” Michel Moor, sitting in an IKea conference room, casts a brief look at the telephone, as he bends forward from his black IKea chair – KLaPPSTa – towards an IKea chest of drawers – GaLaNT. “I’ll give you one.” 22 Rehau unlimited _ 06/13 “a pallet measures 120 x 80 centimeters. That’s the law here. every designer, every technician who works for us bears that in mind. every single component of every new piece of furniture is checked to see if it fits. So, how many components can we stack on a pallet? Only when we’ve reached the optimum amount here do the components go into production.” What that means is there’s no desk at IKea with a length or width of 1.25 or 1.30 meters. Or seen from another perspective, a total of 572 VaLLÖ watering cans can fit on one pallet. When Ingvar Kamprad came up with the idea of using cardboard instead of wood to make the pallet feet, he increased the space available by almost five percent. It practically revolutionized IKea logistics. at IKea, logistics equals ecology, and as Moor likes to admit, also economy. “Protecting the environment and reducing expenditure are two sides of the one coin for us. Think about the amount of energy and materials we save each year by transporting flat packs and pallets. That benefits the environment, too. Why not make the most of both sides?” a quarter of a century of service to one company – that’s another form of sustainability. If it wasn’t obvious before, then as soon as Moor dons his yellow work wear to begin his tour through IKea’s furniture exhibition in Lausanne, it becomes clear now just how connected to his employer he feels. as a recruitment specialist, he knows everyone, greets everyone (IKea staff use informal forms of address with each other); his pace is similar to a Mexican walker (lots of space, little time), and he knows not just every single product, but its histoire too. “Take our KLIPPaN sofa,” he says. “Designed in the midseventies by the Japanese designer Naboru Nakamura. Robust REHAU _ IKEA metal springs that provide real comfort. It fits in almost every living room. KLIPPaN is still around today. Its components have got increasingly smaller. So, we’ve been able to save space and simplify shipping since smaller components mean smaller packages. It all adds up to more sustainability.” While IKea designers have been exhorted to efficiently use recyclable or reusable materials where possible, technicians, too, have to commit to “keeping it simple.” The issue of sustainability also applies to the Swedish furniture store’s suppliers. The “IKea Way on Purchasing Products, Materials and Services”, as known as IWaY, presents an 18-page summary on the “minimum requirements”, which govern the relationship between the supplier and the furniture giant. It includes the prohibition of child labor, the regulation of working hours, compliance requirements, and in numerous variations, declarations of commitment to sustainability. Is this checked? “Oh yes,” says Monsieur Moor, looking earnest, “externally and internally. Frequently. always without warning.” Standards, measurability in general, play an overriding role at IKea, and not just when it comes to kitchen units or the height of chairs. No progress without measurability seems to be the guiding The most stringent requirements for suppliers worldwide. principle born out of experience; and it applies to the environment, too. If the internal environmental goals, such as the annual share of certified wood of the total wood consumption, are not achieved, they are not swept under the carpet; instead, they are mercilessly published – and can easily be viewed online even by the happy family customers. One of the more recent developments in terms of standards is the “Sustainability Product Scorecard”, a scorecard like in golf only the “green” here means “sustainability”. This SPS contains a scale from zero to four hundred – the more points the better. Tested here, among other things, are the cost of materials, the quality, the reusability and separability of the product, as well as the entire level of energy efficiency and use of renewable energies during the production process. To date, the product leader in terms of sustainability is MaLa, a regular standing easel for kids. MaLa meets all the criteria to a high degree, it says in the description, most notably “thanks to its innovative construction”. Yet, despite so much effort, the reward from Sweden is a mere 253 points. a little too self-critical? Or just Nordic understatement? It would certainly appear that even when dealing with the mother of all things sustainable, there’s still room for improvement. < 24 Rehau unlimited _ 06/13 REHAU’s contribution: As one of IKEA’s partners, REHAU is required to adapt eco-friendly production methods and develop resourceconserving products.

REHAU _ Competence 01 “Mr Winterling, where is this journey taking us?” TEXT Katy Hahn PHOTOS Christian Grund Name Ralf Winterling Age 40 years Lives in Erlangen Education Civil Engineer At REHAU since September 2001 Position Technical Manager Projects Mr Winterling, infrastructure is a major issue at REHAU. As Technical Director of the department, what are your responsibilities? Well, we deal with the next stages of the energy transition, with the potentials and the development of the infrastructure on the basis of renewable energies. The things we’re driving forward are not mainstream today, but they could well be in five to ten years. Like for instance, the geothermal activation of urban tunnels. You mean generating heat from tunnels? What does that entail exactly? The so-called tunnel thermics is an advancement of geothermal energy: tunnels are surrounded by soil. This energy potential can be used within the city in subway pipes, for example. Pipes, introduced into the tunnel during its construction, take in the geothermal energy obtained from the earth and supply heat to the buildings coupled to them. In summer, this heat can be passed from the buildings back to the ground. Ralf Winterling, Expert for Infrastructure. 06/13 _ REHAU unlimited 25 REHAU _ Competence 01 In 2011, REHAU received the International Tunneling Award for this. Do we now have any reference projects? As a trailblazer in the field, we’ve launched some initial pilot projects; the Jenbach tunnel in Austria is one example. In the last two years, parts of Stuttgart’s subway network have been converted so that they are able to supply energy for use in the surrounding area. We’re currently in contact with Paris Métro, London Underground, and Copenhagen’s transport authority. There’s a lot of interest, but the gap between what is technically possible and what’s actually doable is still quite wide. Why is that? These kinds of infrastructural changes don’t happen over night. It costs money and more importantly, it takes time. The planning phase for infrastructural changes alone takes up to ten years. Even if the technology has huge potential, it still has to prove itself first. Only in the next decade will it become clear whether our new technologies, including the much-needed expansion of the national grid, will prevail or not. You’re referring to the issue of burying high voltage lines, right? I believe REHAU offers special cable ducts for this. Does this mean overhead power lines will disappear? Burying the lines in the ground is certainly an alternative to the pylons, which are controversial among the population. Being underground, they don’t negatively affect the landscape, and there’s no electrical radiation. Currently, there are four pilot routes identified in Germany, which would suggest that this technology may just get the chance to prove itself. And your company, too ... Naturally, we want to be involved in the construction of these lines; we want to prove how effective and efficient our innovative developments are. The first line is planned for the north of Germany in 2014. We’re currently consulting with the operator. Denmark is a step ahead of us on this one ... There, they’re investing a lot in underground high voltage lines and existing pylons are gradually being phased out. In general, the Danes are very anxious to move forward and bring the infrastructure into line with the rapid growth of renewable energy. But you have to keep things in perspective: Denmark is a lot smaller than Germany. How do things look for the energy giants? The European Union’s goal is to increase the share of renewable energy to 80 percent of its total energy requirements by 2050. The Americans will set themselves a similar goal. And the Chinese, too. It’s a global market worth billions and it will continue to grow. 26 Rehau unlimited _ 06/13 Energy out of the tunnel 1 2 1 Pipes in the concrete structure extract heat from the soil or dissipate waste heat from buildings connected to the system. 2 Precast concrete segments with built-in absorber pipes. In five to ten years, the share of energy derived from renewable sources will exceed 30 percent in Germany. And that figure is set to increase. The share is growing rapidly, but since wind and solar energy are dependent on the weather, we see a lot of fluctuation here. We only have this energy when the sun shines and the wind blows. That means, the yield varies enormously, sometimes being well above the requirement level, sometimes well below. As a result, we need ways to store the excess yield so we can use it when the yield doesn’t meet the requirement. Using regulatable power plants? In part, yes. Regulatable power plants such as the combined heat and power plants, which generate electricity and in the process also useful heat, can compensate for these yield differences. But if the share of renewable energy produced exceeds 40 percent, this ability to compensate reaches its limits. There would have to be lots of available regulatable power plants, which only operate for a few hundred hours per year. Economically, this is not viable, so more storage options are urgently needed. And we already have the technical know-how to do this today. You’re heading in the direction of storable fuels such as hydrogen and geothermics ... We’ve built seasonal geothermal probe heat storage systems, which use the soil as a storage medium in Braedstrup, Denmark, in Crailsheim, Germany, and in Drake Landing, Canada. REHAU _ Competence 01 How does that work? We bury the probes approximately 50 meters underground. During the summer, these circulate water that’s solar heated to 85 °C; the probes then release this heat into the ground. In winter, they draw the heat back from the soil and feed it into the grid. Another project is currently running in Sheffield in the UK. In Patagonia, Argentina, we’re involved in the planning of a hydrogen storage system, which should go into operation in 2014. This is the so-called power-to-gas principle ... Exactly. Electricity from renewable energy can be converted into hydrogen or a substitute natural gas and then stored in the natural gas grid or in underground caverns. Starting any time between 2030 and 2040, solutions like these will be urgently needed. Though what’s not yet clear is whether the distribution of pure hydrogen or a diluted version of methane gas will gain acceptance ... It’s difficult to say. As part of the Patagonia-based pilot project which we’re involved in, we’re providing special multi-layer pipes which are intended to both transport and store underground hundreds of thousands of cubic meters of hundred percent hydrogen gas. Supplying CO2-free energy – REHAU also addresses this issue in its automotive business. Is hydrogen the fuel of the future? Well, profitability is the key issue. But if the reduction of CO2 emissions is further intensified in the automotive industry, then hydrogen and fuel cell technology is the future. With its special manufacturing process for hydrogen pressure tanks, REHAU is prepared for this scenario. The interest shown by car manufacturers also points in this direction. REHAU’s contribution: REHAU is tackling those aspects of the energy transition that are relevant for the future: Including the much-needed expansion of the grid, in which underground installation is becoming increasingly important. And new long-term storage technologies for the provision of an efficient regenerative energy system. RAUGUARD HV – Cable duct The cable duct RAUGUARD HV enables the safe, smooth operation of underground high voltage lines without impacting the environment. The material, adapted for operating temperatures of up to 90 °C, offers long-term stability. A high-sliding interior coating allows the smooth feeding of heavy cable over long routes. Two kilometers of the special quality cable duct will be used during the construction of the first pilot line north of Hamburg. RAU-HY – Hybrid pipe system The RAU-HY, a metal-polymer hybrid pipe system, ensures the safe transport of renewable-fuel-derived hydrogen without conduction losses and without diffusion. It consists of up to five layers: high-pressure crosslinked polyethylene, adhesion promoters, longitudinally welded aluminum and a foamed protective layer for direct installation in the trench.

New technologies and pioneering ideas such as those born at REHAU permit a significant reduction in energy consumption and an efficient and environmentally friendly use of renewable energy – in almost all areas of daily life, worldwide: College – Fraserburgh, Scotland The Banff and Buchan College attracts students from all over the world. Here, in 2011, Scotland’s largest ground-air heat exchanger system was installed. Every hour it sucks in 16,000 cubic meters of outside air and passes it through a special pipe network, which is buried about 1.5 meters deep in the ground. Environmentally friendly and energy efficient, the heat exchange raises the air temperature by up to 9 ºC in winter and cools it by as much as 14 ºC in summer. A smart alternative to energy-guzzling coolant-based refrigeration systems. Radio telescope station – Geraldton, Australia The giant radio telescope station “ASKAP” (36 antennas, each with a diameter of 12 meters) in Western Australia uses renewable energy – among other things, for cooling. 96 geothermal probes buried 124 meters deep noiselessly lead the excess heat from the computer rooms to the surrounding soil. The service life of the double-U probes is over 100 years and long-term safe operation is ensured. In addition to the probes, eight kilometers of RAUGEO PE-Xa connecting lines and 12 RAUGEO midi manifold chambers were laid to join the brine circuits.

One of the most modern plants for drying tropical fruits is located in Ghana, West Africa. Setting standards and operating sustainably with renewable energy, the Swiss-owned company HPW operates amid Ghana’s fruit fields. The plant uses a biogas unit fuelled by crop residues like shells, seeds and stalks to generate its own power and heat. And aiding all of this is the latest technology from REHAU – a digester heating system and district heating pipes which safely transport the heat produced. 30 Rehau unlimited _ 06/13 Project Biogas plant Product RAUBIO digester heating system, RAUTHERMEX district heating pipes Volume 1,000 meters RAUBIO PE-Xa pipes, 150 meters RAUTHERMEX pipes Function Pipe systems for biogas plants, durable and permanently secure REHAU _ Competence 03 Bioenergy Village – San Javier, Spain The bioenergy community of San Javier boasts more than 30,000 inhabitants and is almost self-sufficient, drawing its energy from renewable sources. All around the historic castle, the district heating network RAUVITHERM ensures a reliable supply of thermal energy from nearby fermenters. In the confined spaces of existing buildings and in the leafy palace gardens, the highly flexible pipe could be installed largely without the use of machinery and without any major impact on the unique landscape architecture.

The geothermal potential here is nothing short of huge. An exchange of energy via the concrete structure of the tunnel means that buildings connected to the system can be heated or cooled. The tunnel itself can also be cooled more easily – an important consideration, since high temperatures push air-exchange-based systems to the limit. In the high-speed railway tunnel under the town of Jenbach – a feeder to the Brenner Base Tunnel in the Austrian Inn Valley – are absorber pipes stretching 54 meters inside the concrete walls. A heat-transfer medium (water or water-glycol mixture) circulating in these pipes increases or decreases the temperature of the concrete. Warmth is then extracted from the surrounding soil or the air in the tunnel and used to heat Jenbach’s building yard, which is hooked up to it. Project Thermal activation of tunnel segments Product RAUWAY flex absorber pipes Volume 27 segment rings with integrated absorber pipes (7,000 m) Function Heat exchange with tunnel air or surrounding soil At a depth of about 48 meters, 50 geothermal probes circulate water that has been solar heated to a temperature of up to 85 °C. The surrounding soil is heated and a huge reservoir of heat is created. In winter, this heat is transferred back to the circulating water. 1,200 homes as well as public buildings and factories are connected to the district heating network in Braedstrup. The final stage of the project will provide a total of 60,000 square feet of solar collectors and 300 to 400 probes to store the heat. The goal is to generate 60 percent of the total annual energy requirements from solar energy.

REHAU _ Interview “There’s a revolution in thinking occurring in the Emirates” TEXT Tanja Heinlein PHOTOS Christian Grund > Construction of the eco-city, Masdar City, began in abu Dhabi’s desert in 2008. Though planned for 2016, the mega project probably won’t be finished until 2025. Dr Nawal al-hosany, Director of Sustainability, explains why. > Dr Al-Hosany, let’s be honest: How can the emirate of Abu Dhabi with its huge ecological footprint claim to be a role model for sustainability? The uae is committed to a diversified energy mix. There are several environmental, economic or social benefits to broadening and strengthening our current energy mix to include more sustainable sources of power. While we are at the heart of the hydrocarbon industry, the Middle east and North africa is estimated to hold nearly half of the world’s renewable energy potential. Investing in clean, renewable energy is a natural extension of the uae’s energy leadership. It provides us an opportunity to leverage our existing energy expertise and know-how. By planning ahead and broadening the energy mix to include more sustainable sources of power, we can all be better equipped to meet future energy demand. > So, has the world recognized the need for action? everyone agrees that climate change is a threat that affects all countries. I’m convinced that through education we can bring people to act sustainably out of conviction. The world is hungry for answers to the energy question, also in terms of finite resources. Today, seven billion people live on the planet; by the middle of the millennium, there’ll be nine billion. Providing everyone with affordable energy hardly seems possible without large scale renewable sources. > 40,000 people will live in Masdar City in the future. What makes it one of the world’s most sustainable cities? Masdar City is designed to be one of the most sustainable urban developments in the world. The city combines traditional architecture and design, with modern technologies and applications to make optimum use of the resources available to us in the desert. To date, Masdar City is entirely powered by renewable energy. energy is generated by a ten-megawatt photovoltaic solar farm located onsite. In terms of living, Masdar City combines passive and intelligent design. It has natural shade, narrow corridors and a giant wind tower in the centre that captures prevailing winds, funnelling cool air through the city. By incorporating green and recycled materials that reflect heat and sustainable design 06/13 _ REHAU unlimited 35 REHAU _ Interview principles Masdar City residents can enjoy a noticeably cooler environment – up to twenty degrees cooler than in downtown abu Dhabi. Our buildings are designed to reduce energy demand by fifty-six percent and potable water demand by fifty-four percent. > But we’ve seen approaches like this before on the international stage ... Masdar City was and is certainly a bold statement. Building a “green city” in the middle of the desert may sound utopian at first. But the reality is, we’re experiencing the challenges presented by climate change more acutely here than we ever could in cooler regions. We’re offering the world a chance to view our approaches as recommendations and to adapt them to their respective local conditions. > So, are countries following your green example? In april of this year, the “Sheikh Zayed Solar” power plant in Mauritania which we built, was connected to the grid; it accounts for ten percent of Mauritania’s grid capacity. With strong solar and wind energy sources, the country has the potential to draw a substantial portion of its electricity from renewable sources. To mention another project: The “Port Victoria Wind Power Project”, Masdar’s six MW wind farm in the Seychelles, is the country’s first large-scale renewable energy project. It accounts for more than eight percent of the grid capacity on the archipelago’s main island of Mahe, where ninety percent of the residents live. It truly is a major step toward meeting the Seychelles energy policy, which sets a target of producing fifteen percent of its energy from renewable sources by 2030. With such projects, we want to emphasize that renewable energy is an important component for the successful economic and social development of developing countries. But we’re setting standards in europe, too: With one hundred and seventy-five turbines and a capacity of six hundred and thirty MW, the world’s largest offshore wind farm “London array” supplies energy to around half a million households! > The original completion date for Masdar City was 2016; now that’s been pushed back to 2025. It would seem that the mega project can’t be transferred 1:1 from the drawing board to reality ... Well, the reality is that we’re building a city – and at the same time, a treasure trove of experience. Masdar City is living and learning from local realities. We see how quickly industry is developing here, how much life the city is attracting. The last thing we want is to finish Masdar City as quickly as possible only to discover in the end that the implemented technologies are no longer up to date. Of course, since the start of construction, we 36 Rehau unlimited _ 06/13 have been agile and responsive to changes in the industry or the current economic scenario, by re-evaluating or scaling back on projects that would not be viable. But in just seven years, we’ve managed to filter, enrich, and successfully implement our experience and know-how in projects. Today we’re respected experts – not just in the Middle east, but worldwide. > Living environments that change affect local people in very real ways. What’s the reaction been? Convincing people to choose for a sustainable lifestyle is a process that can’t be completed in a day. abu Dhabi is no different to any other culture in this respect: you need a healthy balance between the environment and the needs of the population. Only through clear messages and concrete recommendations, which also come from abu Dhabi’s leadership, can we bring about change, can we initiate collective efforts. Masdar City is a flagship project; it has sparked a rethinking which has reached both industry and parts of society in equal measure. Slowly but surely we’re integrating sustainability requirements nationwide into our structures – be it in construction, logistics or in the energy sector. This, of course, has an effect on the other emirates as well. > To what extent do you embrace these sustainability principles in your own private life? I’m currently building my house and working closely with the architects and the contractors to incorporate sustainability and energy efficiency in every phase of the project. I consult in choosing all my suppliers to ensure that the materials and appliances that are used in my house are sustainable. I hope that those who visit my house will be inspired and incorporate sustainability into their daily lives. > As a leader, you’re held in very high repute internationally. Have women been accepted into the upper echelons of energy politics? Well, it’s always about the respective capabilities. But I personally find it very refreshing to see how female executives are being promoted in the uae. Our former president Sheikh Zayed bin Sultan al Nahyan said in 1971: “Nothing could delight me more than to see the woman taking up her distinctive position in society. Like men, women deserve the right to occupy high positions according to their capabilities and qualifications.” I personally feel this maxim is ingrained in our culture, in all areas of public life, in politics as well as in business. In international discourse, however, women must step forward more. Climate change affects women just as much as men. So, they should be equal partners in dialogue. having said that, I believe women are affected by REHAU _ Interview Modern urbanity in the desert. climate change in a different way, especially in structurally weak countries. They make up the majority of the 1.2 billion people living in absolute poverty worldwide. Yes, perhaps for this reason women should have a stronger voice in the climate debate. > You climbed Mount Kilimanjaro in 2010. And you were one of the first Arab women to do it. How has this experience affected you? It’s made me stronger as a person, changed my outlook on life. It was about dealing with fears and personal insecurities. Perhaps these things won’t change your life, but they definitely make you a better person. Energy efficient architecture. Dr Nawal Al-Hosany is Masdar’s Director of Sustainability and an internationally acclaimed expert in her field. In this capacity, she is responsible for the sustainability policies and standards for the eco-city, which is located around 17 km from Abu Dhabi. Al-Hosany grew up in the United Arab Emirates, where she completed an engineering degree. She earned her doctorate at the University of Newcastle upon Tyne in England and also attended the prestigious Harvard Business School in Cambridge, Massachusetts. Prior to her work in Masdar City, she was Deputy Director of Planning for Abu Dhabi’s police force; she was the first woman to hold this position. In 2008, she was presented with the “Emirates Businesswoman Award.” Two years later, in 2010, she was one of the UAE’s first women to climb Kilimanjaro. > How do you envision “sustainable living”?
