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.

Danish greentech company GreenGo Energy has announced plans to develop, in cooperation with the Ringkøbing-Skjern municipality, a green energy park based on 4 GW of hybrid solar and wind energy, which is to be fed directly to the energy park, at the core of which will be a 2 GW green hydrogen production plant.
Element Resources has announced its plans to build and operate a major renewable hydrogen production facility in the City of Lancaster in California, less than 100 miles from the ports of Los Angeles and Long Beach. Element Resources will produce 20,000 tons of renewable hydrogen annually through its first phase.
On 20 January, the foundation stone of P2X Solutions’ green hydrogen and synthetic methane production plant in Harjavalta was laid. Scheduled to be completed in 2024, the facility is Finland’s first industrial-scale green hydrogen production plant that is progressing to the construction stage.
Nickel-iron catalysts are promising materials for the production of green hydrogen, but they are limited by the easy dissolution of Fe inside water-splitting cells. Now, South Korean scientists have developed a novel TTP protection layer that dramatically increases the life and performance of Ni-Fe catalysts.
German electrolyzer manufacturer Sunfire and Vitesco Technologies have announced the formation of a strategic partnership, which will allow Sunfire to use the automotive supplier’s expertise to transfer its hydrogen technologies to industrial serial production, thereby opening a new chapter for both companies.
In an effort to support growing demand for clean hydrogen generation, Chemours has announced a USD 200 million investment to increase capacity and advance technology for its Nafion™ ion exchange materials, to be located at the company’s manufacturing facility in Villers-Saint-Paul, France.
Hydrogen technology development is shifting towards low-emissions solutions such as electrolysis, according to a joint study of patents by the European Patent Office (EPO) and the International Energy Agency (IEA). The freely-available study is the most comprehensive investigation of hydrogen-related patenting so far.
Everfuel A/S has announced the production of first hydrogen at its HySynergy facility in Fredericia, Denmark. The initial production is the first step towards ramping up the electrolyser facility to supply green hydrogen to customers. Commercial production is expected to commence in the second quarter of 2023.
Engineers from RMIT University in Melbourne, Australia, have said that by using high-frequency vibrations to divide individual water molecules during electrolysis, the team managed to split the water molecules to release 14 times more hydrogen compared with standard electrolysis techniques.
H2U Technologies has demonstrated proton exchange membrane electrolyzer stacks that replace expensive and scarce iridium catalysts with inexpensive and abundant catalyst materials. The company’s electrolyzer stacks leverage readily available catalyst materials to enable cost-effective green hydrogen generation.
