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.
Nel Hydrogen US has entered into a joint development agreement with General Motors to help accelerate the industrialization of its PEM electrolyser platform. By combining their expertise in electrolysers and fuel cells respectively, Nel and GM aim to enable more cost-competitive sources of green hydrogen.
Engineering company Wood has been awarded the front-end engineering design (FEED) scope for Gen2 Energy’s green hydrogen production facility located in Mosjøen, northern Norway. The new 100 MW plant will be the first large-scale commercial green hydrogen production facility in Norway.
Japanese multinational Asahi Kasei has started the construction of an alkaline water electrolysis pilot test plant for hydrogen production at its Kawasaki Works location in Kanagawa Prefecture, Japan. Start of operation is targeted in early 2024, following construction work, equipment installation and trial operation.
McPhy Energy has announced the final investment decision (FID) for its Gigafactory of alkaline electrolyzers on the Belfort site in France, taken by its Board of Directors on 26 October. Commissioning is scheduled for the first half of 2024, with a gradual ramp-up to reach an annual production capacity of 1 GW.
On 1 November, Bloom Energy inaugurated its high-volume commercial electrolyzer line at the company’s Newark, Delaware facility, increasing its generating capacity of electrolyzers to 2 GW. The award-winning technology is said to be the most energy-efficient design to produce clean hydrogen to date.
NewHydrogen will further expand the existing sponsored research agreement with UCLA to develop technology to reduce the cost of green hydrogen production. The expanded program scope will include the development of efficient and stable hydrogen production using PEM electrolyzers.
Alfa Laval has signed an agreement to deliver compact heat exchangers to the world’s largest green hydrogen plant, to be constructed in the Middle East. The facility will be part of the city of Neom, built from scratch in the northwestern desert, with the ambition of establishing a new model for sustainable living.
In a serendipitous scientific discovery, a team of researchers from the National University of Singapore have found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis. The result is a more energy-efficient – and potentially revolutionary – method of obtaining hydrogen.
In what is seen as a major breakthrough, researchers of the Dutch applied technology institute TNO have developed an advanced electrocatalyst that reduces the required amount of iridium by a factor of 200, while achieving an average of one third of the performance of current PEM electrolysers.
H2U Technologies has announced its patented Catalyst Discovery Engine (CDE), which advances the identification of catalyst alternatives to costly and scarce iridium and other rare platinum group metals (PGM) used in electrolyzers to produce hydrogen.
