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.
DENSO Corporation and JERA Co., Inc. have announced that they will jointly develop high-efficiency hydrogen generation technology that combines SOEC with waste heat utilization and conduct joint demonstration testing at a JERA thermal power station.
Siemens Energy has been awarded a contract to supply a 280-megawatt electrolysis system by German utility EWE. The plant in the German city of Emden is expected to go into operation in 2027 and will provide up to 26,000 tons of green hydrogen annually for various industrial applications in the region.
Shell Deutschland GmbH has taken a Final Investment Decision (FID) to progress REFHYNE II, a 100-MW PEM electrolyser at the Shell Energy and Chemicals Park Rheinland in Germany. Using renewable electricity, REFHYNE II is expected to produce up to 44,000 kilograms of hydrogen per day to partially decarbonise site operations.
Ceres has signed a global long-term licence agreement for the manufacture of its proprietary solid oxide electrolyser cell (SOEC) technology with a global original equipment manufacturer (OEM) headquartered in the Asia Pacific region. The agreement provides revenues for licence fees, engineering services and hardware over multiple years.
3M has completed a strategic investment in Ohmium International, a developer of PEM electrolyzer systems for green hydrogen production. This investment is part of 3M’s commitment to advancing technologies that support the transition to a low-carbon economy and may also help the company further decarbonize its own operations.
ITM Power has signed a 500 MW capacity reservation with a global industrial customer. This reservation secures future production capacity for the manufacturing of ITM’s electrolyser stacks through the end of the 2028 calendar year and foresees call-offs against future projects in Europe and the US.
Spanish firms Matteco and Ariema Enerxía have received EU Next Generation funding to deploy advanced technology in alkaline electrolyzers. Matteco will implement its components in a new generation of alkaline electrolyzers from Ariema, aiming to produce green hydrogen more efficiently and at a lower cost.
SoCalGas and EVOLOH, an anion exchange membrane (AEM) electrolyzer technology developer, have completed a joint research project that resulted in enhancements to the current electrolyzer manufacturing process and technology.
Green Hydrogen Systems A/S has completed phase 1 of the reliability testing of the X-Series electrolyser prototype. This milestone allows the company to release the X-Series product for binding contractual commitments on a performance-based price structure.
F2N Green Hydrogen Srl (FGH), an innovative Italian start-up based in Varese and specializing in water electrolysis technology, has announced the completion of the internal qualification tests and the commercial launch of their alkaline stack product line, CORNERSTONE.
