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.

H-TEC SYSTEMS has unveiled its Hydrogen Cube System. The modular system is suitable for large multi-MW PEM electrolysis plants and applications in the industrial, chemical, and renewable energy sectors.
Plug Power has been awarded an order to deliver a 1 GW electrolyzer to H2 Energy Europe. Planned for a green hydrogen production complex in Denmark, this is the largest-capacity electrolyzer installation in the world to date.
On Friday, 13 May, Spanish King Felipe VI inaugurated Iberdrola’s green hydrogen plant in Puertollano. The solar-powered facility will be able to produce up to 3,000 tonnes of renewable hydrogen per year.
The new funding round, led by Doosan Corporation, will support the development and prototype of Versogen’s next-generation electrolyzer stacks and expand the production of their patented anion exchange membranes (AEM).
The investment will support Elcogen’s planned expansion of its facilities in Tallinn to create a new, automated production line for solid oxide fuel cells and stacks, initially scaled at 25 MW/year, rising to 50 MW/year (equivalent to 100–200 MW in electrolysis mode).
Bosch has announced its plans to develop components for electrolyzers, drawing on its expertise in fuel cell technology. The company will invest up to €500 million in this new area of business by 2030.
In a bid to contribute to the economically viable production of electrolyzers and fuel cells, Fraunhofer IWU has designed Reference-factory.H2. The concept provides both a design for guidance and a modular system based on new and specifically optimized technologies.
TNO, Johnson Matthey, Bekaert, and Schaeffler have formed a partnership to develop a new generation of electrolysers. The consortium aims to develop cells to be used within electrolysis with the components optimized to work together for a step-change in efficiency.
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).
