Water electrolyzers are electrochemical devices used to split water into its constituent elements, hydrogen and oxygen, by passage of an electrical current. There are four main types of electrolyzers: alkaline and proton exchange membrane (PEM) electrolyzers are already mature, while anion exchange membrane (AEM) and solid oxide electrolyzers are still under development. These technologies differ in numerous ways, most notably in cell design and variations within components. In this section you can find news items related to various aspects of electrolyzer technologies, equipment and components. If you would like to see your news release published here and in our email newsletter, please feel free to contact Matjaž Matošec.
Nel has opened a new electrolyzer production facility at Herøya, Norway. This pioneering plant, which is fully automated, currently has 500 MW of production capacity for alkaline electrolyzers. With further investment, this figure can be quadrupled to reach 2 GW.
German steel group Salzgitter AG has reported an efficiency of 84% for its EU-funded GrInHy2.0 hydrogen project with a high-temperature electrolyzer from the Dresden-based company Sunfire. The record value was achieved with the help of solid oxide electrolysis technology (SOEC).
Greenko ZeroC and John Cockerill have signed an agreement to jointly manufacture green hydrogen electrolyzers in India. The two companies will build an electrolyzer gigafactory targeting a capacity of two gigawatts, which will substitute 8% of India LNG imports.
Torvex Energy has validated an innovative and ‘game-changing’ method of generating environmentally friendly hydrogen from seawater that does not produce oxygen gas. The proof of concept was established in collaboration with the Material Processing Institute.
Tokyo-based classification society ClassNK has issued an Approval in Principle (AiP) for the design of a floating offshore hydrogen production plant developed by the Japan Offshore Design & Engineering Platform Technology & Engineering Research Association (J-DeEP).
Siemens Energy will locate the industrial production of electrolysis modules in Berlin and is thus taking the centerpiece of its hydrogen technology to the German capital. Start of production at the location Huttenstrasse in Berlin’s Moabit locality is scheduled for 2023.
De Nora and H2U Technologies have announced a joint development agreement to assess the viability of newly identified non-platinum group metal catalysts for water electrolysis. Through their partnership, De Nora will help bring H2U’s earth-abundant catalysts to the electrolyzer market.
The Research Council of Norway is investing more than €20 million in HYDROGENi, a new centre for environment-friendly energy research (FME) dedicated to hydrogen and ammonia. The centre has enlisted a strong cluster of over 50 industrial and academic partners.
Ground-breaking research has confirmed that Hysata’s ‘capillary-fed electrolysis cell’ can produce green hydrogen from water at 98% cell energy efficiency, well above IRENA’s 2050 target, enabling a hydrogen production cost well below A$2/kg (US$1.50/kg).
The Clean Hydrogen Partnership has launched its first call for proposals through which it will support projects that boost renewable hydrogen production, reduce its costs, develop storage and distribution solutions, and stimulate the use of low-carbon hydrogen in hard-to-abate sectors.
