NEWELY is a EU Horizon2020 project that deals with the development and testing of components for the next generation of Anion Exchange Membrane Water Electrolysers (AEMWE). With the innovations on the membrane, electrodes and stack design, the NEWELY prototype will become the most efficient and cost-competitive AEMWE by 2023. NEWELY will be an important breakthrough that will enable the economic adoption of green hydrogen energy storage solutions in Europe and in the world for turning to more sustainable energy systems.
