German manufacturer Nordex Group has taken a significant step in advancing green hydrogen production in Spain with the development of a 500 kW pressurised alkaline electrolyser. This electrolyser, the largest ever manufactured in Spain, was designed, manufactured, and assembled in the country by Nordex Electrolyzers, a joint venture between Nordex and the Government of Navarra. The European Commission has provided financial support to Nordex Electrolyzers' project through the IPCEI Hy2Tech programme, facilitating the production of a series of electrolysers focused on energy efficiency and flexibility. The 500 kW electrolyser prototype aims to produce hydrogen with reduced energy consumption and work effectively with power changes and frequent stops. Despite challenges faced by green hydrogen projects globally, such as the reported inefficiencies in some electrolysers, Nordex Group remains committed to integrating green hydrogen production into its value chain by 2026. This move aligns with efforts to reduce carbon emissions associated with hydrogen production and promote the use of renewable energy sources in the electrolysis process. The development of this prototype marks a significant milestone in Spain's efforts towards sustainable hydrogen production and signifies a positive advancement in the country's green technology sector.
