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.

Researchers from the University of Adelaide have successfully split seawater without pretreatment to produce green hydrogen. The team will now work on scaling up the system by using a larger electrolyser, so that it can be used in commercial processes such as hydrogen generation and ammonia synthesis.
Linde has announced plans to increase its green hydrogen production capacity in Ontario, California, in response to growing demand from the mobility market. The company will build, own and operate the first of several planned 5 MW PEM electrolyzers to increase its hydrogen capacity.
Plug Power and Johnson Matthey (JM) have announced a long-term strategic partnership to accelerate the green hydrogen economy. JM will become an important strategic supplier of MEA components, providing a substantial portion of Plug’s demand for catalysts, membranes, and catalyst coated membranes (CCM).
Implementation of the Swedish ‘Project Air’ is moving full steam ahead. Uniper has commissioned Dresden-based Sunfire to build a 30 MW pressurized alkaline electrolysis plant, which will generate green hydrogen using renewable electricity and purified wastewater. The final investment decision is still pending.
GET H2, one of the most advanced hydrogen projects in Germany, is picking up the pace. RWE has ordered two 100 MW proton exchange membrane (PEM) electrolysers from Linde Engineering. RWE plans to commission the first of the two plants in 2024 on the site of its gas-fired power plant in Lingen.
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.
