The purpose of the association is to promote and support the development of innovative technologies and human resources to enable a prompt transition to a sustainable energy system. The Renewable Energy Projects Catalogue- A guide to innovative and successful projects in the area of renewable energy presents a list of projects, led by EUREC members, which have contributed to increase the presence of renewable energies in the energy mix, by reducing their costs, increasing their reliability or facilitating their integration in the energy system. The Catalogue is divided in four main chapters dedicated to: • RENEWABLE ELECTRICITY (e.g. PV, wind, biomass, solar thermal, ocean, hybrid systems) • RENEWABLE HEATING AND COOLING (e.g. heat pumps, solar thermal) • SUSTAINABLE TRANSPORT (fuel cells and biofuels) • HORIZONTAL TOPICS (e.g. grid integration and energy storage, studies to support transition to sustainable energy, education and training activities) Each chapter presents examples of successful and innovative projects in its respective area. The Renewable Energy Projects Catalogue highlights the richness of renewable energy research, which covers different renewable energy sources with different research needs, all along the resource value chain (e.g. from production of the source- whenever needed- to the production of the generation The Catalogue also presents examples of horizontal topics, such as grid integration, building integration, energy efficiency, energy storage, education and training activities, whose importance has grown in recent years.

One of those aspects was related to the approach used for the definition of the PV competitiveness, which was until now usually referred only to a static comparison between the evolution of PV generation cost and electricity prices for the residential market segment. The definition of PV competitiveness in the PV Parity project was a dynamic definition developed for each market segments (residential, commercial and utility), which took into account all relevant aspects related to the PV electricity generation including the costs and benefits of PV integration into the electrical grid and the environmental costs and benefits related to the PV electricity generation (Figure 1). Per each type of consumer, roadmaps towards the PV competitiveness have been developed for 11 target countries: Austria, Belgium, Czech Republic, France, Germany, Greece, Italy, Portugal, Spain, The Netherlands and United Kingdom (Figure 2 and 3). The integration cost of PV into the electrical grid is relatively modest (up to 26 €/MWh by 2030 to integrate up to 485 GWp into the electrical grid) and confirms the increasing of the PV attractiveness for European economy.

In the past decade, the deployment of PV in Europe has been mainly facilitated by feed-in tariffs or similar schemes. Many countries were surprised by the dynamics of PV installations and they failed in some cases to adapt the level of financial support in due time. The existing support schemes have to be readjusted in order 14 EUREC Renewable Energy Projects Catalogue Figure 3 – Achievement of PV competitiveness in the residential sector in 2020 © TUW-EEG EUREC Renewable Energy Projects Catalogue 15 R E N E WA B L E E L E C T R I C I T Y Main features of the project to integrate new alternative incentives such as 5 .

The potential of CPV is based on the use of very high efficient and, therefore more costly solar cells, made from III-V semiconductor materials, which are standard in space applications, but would not be affordable in flat-plate approaches. Inexpensive lenses or mirrors are used to strongly concentrate the light and hence reduce the required solar cell area.

Its large auditorium can be automatically transformed from a 3,000-seat amphitheatre to a 1’800 m2 banquet hall. The STCC was designed according to sus- tainable principles by combining several Renewable Energy Technologies (BiPV, solar thermal, heat pumps, geothermal pillars, daylighting, etc.) with a mixed use of CONTACT DETAILS Philippe Vollichard, [email protected] Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland FOR MORE INFORMATION: http://tstcc.ch/fr/index.php and users comfort. A maximal use of daylighting is also made in the basement. A transparent and coloured glazing performs the double function of sun shadings and solar electricity generation for the STCC Western façade. It is the first large-scale implementation of the Dye Solar Cells (DSC), invented by EPFL Professor Michael Grätzel and manufactured by a local “Start-up” company. RESULTS eco-friendly mobility (metro line, electric vehicles).. The DSC power plant produces annually 2,000 kWh of Space heating and cooling The core energy concept of STCC is the use of heat rejection from the water circulating in the buildings of the EPFL campus originally pumped from Lake Geneva.

Energy storage, as part of an integrated approach including grid reinforcement and demand management, helps to accommodate higher percentages of variable renewable energy by balancing the supply and demand and improving the power quality. Even if we assume the existence of a supergrid there is a certain need for new energy storage capacity in Europe. This need for storage has to be recognized at EU/national policy level in order to facilitate project development. The framework conditions such as the power system characteristics, the market operation and the regulations vary significantly from one Member State to another creating an environment for energy storage that does not reflect the relevant needs. There is a lack of wide acceptance of the need for storage, limited understanding of the challenges, and no common vision of the future of energy storage among the relevant stakeholders. Main features of the project stoRE dealt with the non-technological barriers to en- and market mechanisms. The possible positive and negative impacts of the different energy storage options on the environment were also assessed and the considerations of the relevant actors were taken into account. Consultation processes, policy debates Co-funded by the Intelligent Energy Europe Programme of the European Union and communication activities ensured that the project is open to all key actors and target groups, with results representing the whole energy sector and the society. RESULTS 1. The environmental performance of energy storage installations was assessed. Together with all key actors the stoRE project formulated recommendations for improving the framework conditions. 2. The European regulatory and market framework conditions were assessed with inputs from stakeholders representing all interested parties, resulting in concrete recommendations for improvements. 3.
