High-efficiency, low-cost electrode-surfaces for next generation alkaline electrolysis

In the future, storage of energy from renewable energy sources will be crucial. Hydrogen, elec- trolysis and synthetic fuels make it possible. The storage of energy from renewable energy sources is a global challenge. The need for solutions in- creases as solar power and wind power contribute increasingly to our energy production. The production of hydrogen by electrolysis is a proven technology, albeit with a potential for improvement of efficiency and reduction of cost. The main objective is to develop electrolysis technology to secure and expand the Danish edge on renewable energy technology and storage, e.g. by full upgrading of biogas to natural gas, where the CO2 content by reaction with hydrogen is upgraded to methane. The project focuses on advances within material science and electrochemistry. Research in electrocatalytic surfaces helps to develop efficient and durable electrodes, produced by scalable and cost-friendly synthesis without use of noble metals. The electrolysis shall be demonstrated in a design, which can be scaled to store energy from a modern wind turbine.
