efficient hydrogen production with norwegian electrolyser technology
RENEWABLE HYDROGEN PRODUCTION WITH NORWEGIAN ELECTROLYSER TECHNOLOGY Workshop «Hydrogen & brenselceller i maritim sektor» Bergen – September 3rd – 2014 Henning G. Langås, NEL Hydrogen 29.10.2014 1 NEL HYDROGEN - KEY FACTS • • • • • • Norwegian, private unlisted company > 20 employees Business: water electrolysers Worldwide presence with customers in more than 50 countries Revenues ~ 10 million € Profitable company 29.10.2014 2 NEL HYDROGEN MILESTONES Norsk Hydro started its electrolyser development and installation for large scale hydrogen production at its ammonia fertilizer plants in Rjukan, Norway 1927 Norsk Hydro Electrolysers (NHEL) established as a separate company, owned by Norsk Hydro NHEL delivered the world’s first public available hydrogen fuelling station 1993 2003 1974 Commercial sales of electrolysers commenced in the 1970s 29.10.2014 2001 NHEL’s first pressurised electrolyser introduced 3 2007 Hydrogen Technologies’ 500th electrolyser delivered 2008 NHEL is renamed to Hydrogen Technologies in 2006. In 2007 Statoil became the owner of Hydrogen Technologies as a result of the Statoil-Hydro merger 2011 Statoil sold Hydrogen Technologies and the company was renamed NEL Hydrogen CONCEPT OF WATER ELECTROLYSER Water H2O Energy Hydrogen H2 Electrolyser Oxygen O2 This shows the concept of producing hydrogen through electrolysers. All you need is water and energy to feed into the electrolyser, in which the electric current splits the water molecule into hydrogen and oxygen gas. Given that the energy is from renewable sources, you have a production chain with zero emissions of greenhouse gases. 29.10.2014 4 ELECTROLYSER IN HISTORICAL CONTEXT COAL GASIFICATION 1800’s – 1920’s WATER ELECTROLYSIS 1920’s – 1960’s GAS REFORMING 1950’s – TODAY H2 ECONOMY? 2010 – 29.10.2014 5 REVITALISATION OF GREEN H2 PRODUCTION 29.10.2014 6 HISTORICAL LARGE SCALE PLANTS Rjukan, Norway; 1927 – 1970’s • • • • Glomfjord, Norway; 1953 – 1991 Two largest electrolyser plants worldwide Capacity: 30 000 Nm3/h each Energy consumption: approximately 135 MW each Supplied by renewable hydro power 29.10.2014 7 NEW LARGE SCALE PLANTS Company: Nitol Solar Industry: Polysilicon Start-up: 2011 Capacity: 1 940 Nm3/h Energy: 8,8 MW Source: Hydro Power x x Company: Tokuyama Industry: Polysilicon Start-up: 2012 & 2013 Capacity: 2 500 Nm3/h + 3 000 Nm3/h Energy: Total 25 MW Source: Hydro Power 29.10.2014 8 H2 ECONOMY + Renewable power POWER-TO-GAS (PtG) = 29.10.2014 H2 MOBILITY / FUEL FOR TRANSPORT NEED FOR ELECTROLYSERS 9 POWER-TO-GAS - UTILISING EXCESS RENEWABLE POWER Power grid Hydrogen vehicle CO2 H2 CH4 METHANISATION H2 Renewable power 29.10.2014 Energy Natural gas grid Electrolyser 10 POWER-TO-GAS: UTSIRA Utsira - Supplying an island with renewable energy 29.10.2014 11 UTSIRA RENEWABLE HYDROGEN SYSTEM: HOW IT WORKS 29.10.2014 12 H2 MOBILITY: ICELAND & GERMANY • ICELAND: Delivering world’s first public available hydrogen station • GERMANY: Pioneer in development of the hydrogen infrastructure with stations in Hamburg and Berlin 29.10.2014 13 CHALLENGES? • How to make a business case for PtG and H2 mobility including water electrolyser technology? • CHALLENGE? – Cost? – Technology? 29.10.2014 14 COST; CAPEX • Today’s demo-projects are often small in size • Consequence; huge CAPEX per Nm3/kg/MW hydrogen produced. CAPEX 50 Nm3/h plant (250 kW): • € 500.000 – 600.000 • € 10.000-12.000 per Nm3/hour • € 130.000 per kg/hour Capex reduced to 1/3 per unit by increasing plant capacity by 10 times CAPEX 500 Nm3/h plant (2,3 MW): • € 1.500.000 – 1.800.000 • € 3.000-4.000 per Nm3/hour • € 35.000 – 40.000 per kg/hour 29.10.2014 15 CAPEX COSTS LARGE SCALE 1 400 1 200 15 bar Atmospheric 1 000 15 bar + installation & commissioning € / kW 800 600 400 200 Plant's capacity MW 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 29.10.2014 16 COST; OPEX 1. Get right technology! – – – Stable operation No shut-downs Minimum maintenance 2. Focus on energy efficiency – 29.10.2014 If technology is right; energy cost is > 90% of OPEX 17 KEY FOR SUCCESS: 1. Go large 2. Reliability & efficiency 29.10.2014 18 18 REFERENCES – WIDE RANGE OF INDUSTRIES 29.10.2014 19 29.10.2014 20 THANK YOU! 29.10.2014 21
