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.
JERA and DENSO have begun demonstration testing of hydrogen production at JERA’s Shin-Nagoya Thermal Power Station in Nagoya, Aichi, using solid oxide electrolysis cell (SOEC) systems developed by DENSO. The system has an electrolysis capacity of 200 kW.
Laufenberg and Wevo-Chemie have developed a process that enables the continuous, roll-to-roll production of flat elastomer gaskets for fuel cells, electrolysers, and redox flow batteries. The innovation replaces time- and cost-intensive moulding methods with a scalable, automated approach that increases manufacturing efficiency.
KITZ Corporation has announced plans to launch its first proprietary Proton Exchange Membrane (PEM) water electrolysis hydrogen generation unit, signalling the company’s entry into the green hydrogen market.
Singapore-based Horizon Fuel Cell Technologies, through its electrolyser subsidiary HET Hydrogen, is preparing to deploy a 5 MW anion exchange membrane (AEM) electrolyser system with a subsidiary of Rockcheck Steel Group Co Ltd in Tianjin, China. Expected to become operational by the end of 2025, the installation is described as a world-first at this scale for AEM technology.
Asahi Kasei will supply its Aqualyzer™-C3 containerized 1 MW-class alkaline water electrolyzer to a hydrogen production initiative led by the Central Finland Mobility Foundation (Cefmof). The system is expected to begin full operation in the first half of 2026 and will support efforts to decarbonize Central Finland’s transportation sector.
Air Liquide has taken the final investment decision to build ELYgator, a 200 MW electrolyzer in Maasvlakte, in the Port of Rotterdam. The facility will combine PEM and alkaline technologies on the same site – a first of its kind – and is expected to be operational by the end of 2027.
DNV has completed a comprehensive technical review of Electric Hydrogen’s HYPRPlant, validating its alignment with current industry standards for process design, safety, and manufacturing process.
L&T Energy GreenTech Ltd (LTEG), a wholly-owned subsidiary of Larsen & Toubro, will establish India’s largest green hydrogen plant at Indian Oil Corporation Ltd’s (IOCL) Panipat Refinery in Haryana.
Battolyser Systems and VDL Hydrogen Systems, two Dutch electrolyser developers, have agreed to merge their activities into a single company with the aim of bringing a fully flexible electrolyser for large-scale industrial applications to market.
Hygreen Energy, a Beijing-based global electrolyser manufacturer, has signed a multi-year frame agreement with Robert Bosch GmbH to integrate Bosch’s Hybrion PEM electrolysis stacks into its portfolio of large-scale hydrogen production systems.
