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.

LONGi Hydrogen, a wholly owned subsidiary of China’s solar giant LONGi Green Energy Technology, has launched its new generation of alkaline electrolyzers. The performance of the ALK Hi1 series products has been certified by third-party authorities such as Det Norske Veritas and DEKRA Testing and Certification (Shanghai).
FuelCell Energy and Malaysia Marine and Heavy Engineering, a wholly owned subsidiary of Malaysia Marine and Heavy Engineering Holdings Berhad (MHB), have signed a memorandum of understanding to jointly develop large-scale solid-oxide electrolyzer facilities in Asia, New Zealand and Australia.
Lhyfe has obtained the construction permit for its second green hydrogen production site in the Morbihan region of Brittany, France, and is about to begin preparatory construction work. Lhyfe Bretagne will have the capacity to produce up to 2 tonnes of green and renewable hydrogen per day (5 MW).
In La Robla, Spain, Enagás Renovable and Naturgy plan to construct a renewable hydrogen plant with a production capacity of up to 280 MW. Scheduled to start up in 2026, the plant will be located on the site of Naturgy’s former thermal power plant, which is currently in the process of being decommissioned.
RMIT University researchers have developed a cheaper and more energy-efficient way to make hydrogen directly from seawater, skipping the need for desalination and its associated cost, energy consumption and carbon emissions. What is more, the new process generates no chlorine as a by-product.
SunHydrogen, the U.S. developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, has published a photo of the largest version to date of its nanoparticle-based green H₂ technology, designed to be economical at mass-manufacturing scale.
South Korean scientists investigated a synthetic method to develop new metal oxyhydroxides electrocatalysts for water electrolysis. The study summarising their findings details the process, demonstrating the long-term stability and performance of the synthesized catalysts.
Dresden-based Sunfire has successfully commissioned its high-temperature co-electrolysis plant, which forms an important part of the Kopernikus P2X research project. Funded by the German Federal Ministry of Education and Research, the project studies power-to-x technologies.
Hynamics, the hydrogen subsidiary of EDF group, has signed an agreement to collaborate with ABB and test the ABB Ability™ OPTIMAX® for Green Hydrogen energy management system (EMS) across its plants to help optimize electrical costs of hydrogen production by up to 16%, according to ABB modelling.
HyCC has selected Kraftanlagen Energies & Services to provide engineering services and Nel as a technology supplier for its green hydrogen project H2eron in Delfzijl, the Netherlands. The 40 MW plant is to produce the first hydrogen in 2026 to support the production of sustainable aviation fuels.
