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.
Smoltek Nanotech Holding AB has developed a porous transport electrode (PTE) that reduces the amount of iridium catalyst in PEM electrolyzers to a minimum of 0.1 mg/cm² – the level considered necessary to make large-scale production of PEM electrolyzers profitable.
Nel ASA and its subsidiaries have initiated a process to adjust capacity to market demand by reducing the workforce and temporarily halting production at the alkaline production facility in Herøya, Norway.
Topsoe has selected New Energy Risk (NER), a provider of technology performance insurance, as the preferred insurance partner for its SOEC hydrogen electrolyzer products.
IMI is set to provide a PEM electrolyser for a new hydrogen refuelling station at the Port of Klaipėda in Lithuania, to be developed by EPC contractor MT Group. This project will position the Port of Klaipėda as the first in the Baltic region to produce green hydrogen on-site.
DNV has released a new standard, Electrolyser Systems DNV-ST-J301, embedded in DNV’s certification framework for the equipment and facilities used in producing hydrogen and its derivatives through water electrolysis.
CSIRO, Australia’s national science agency, has successfully trialled its innovative hydrogen production technology at BlueScope’s Port Kembla Steelworks in New South Wales, demonstrating that affordable and renewable hydrogen can be generated at scale to help decarbonise heavy industry.
XINTC, a Dutch initiative funded entirely by private Dutch investments, has unveiled a revolutionary electrolyser design featuring an all-plastic gas module (stack). This innovation eliminates the need for critical metals, membranes, and seals, paving the way for the mass production of virtually maintenance-free electrolysers.
Hystar today hosted an event at the Kårstø Gas Processing Plant in Rogaland, Norway, to formally open its field project, HyPilot. The Kårstø plant is hosting the HyPilot project at its K-Lab test centre. HyPilot is the in-field demonstration of Hystar’s 1.5-MW containerized PEM electrolyser.
SolydEra and Dynelectro have transitioned from a Memorandum of Understanding (MOU) to a formal collaboration agreement, marking the start of a strategic partnership. This agreement aims to deliver a 1-MW solid oxide electrolyser by September 2025.
Uniper has selected Electric Hydrogen as its exclusive partner to design a 200-MW electrolyzer plant for large-scale electrolysis within Uniper’s Green Wilhelmshaven project in Northern Germany. Electric Hydrogen began conducting the preliminary front-end engineering design (pre-FEED) work for the project in October 2024.
