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.

Topsoe, ABB, and Fluor have formed an alliance to design a standardized concept for building Topsoe’s next SOEC factory. The aim is to continuously develop processes to reduce costs, enhance safety, and secure an efficient project execution via a standardized approach.
Today, Nordex Electrolyzers – a joint venture between the Government of Navarra and the Nordex Group – inaugurated a test bench at its plant in Lumbier, Spain. The company presented its first in-house-developed prototype of a 500-kW pressurized alkaline electrolyzer to the public.
Nordic energy company Fortum will build a hydrogen production plant in Loviisa, 90 km east of Helsinki. The plant, equipped with Stargate’s electrolyser, will be located near Fortum’s Loviisa nuclear power plant at the Kalla Test Center. Construction is set to begin in summer 2024, with commissioning scheduled for late 2025.
Elcogen has announced that it has recently initiated a collaboration agreement under the Important Projects of Common European Interest scheme (IPCEI) with the Dutch Organization for Applied Scientific Research (TNO) to develop advanced solid oxide electrolysis (SOE) technology for future market demands.
Ceres has been awarded a further contract for the second phase of its collaboration with Shell, to cooperate in the design of a 10 MW solid oxide electrolyser (SOEC) module to produce green hydrogen for use in large-scale industrial applications such as synthetic fuels, ammonia, and green steel.
Researchers at DTU have fabricated and tested a new type of ceramic electrolysis cells with Ni-GDC fuel electrodes and demonstrated that instead of wearing out, the electrodes maintain their performance. Electrolysis cells play a key role in converting electricity from wind turbines and solar cells into fuels such as hydrogen, methanol, and ammonia.
Hindustan Petroleum Corporation Limited (HPCL) has commissioned India’s first solid oxide electrolyser for green hydrogen production at its Green R&D Centre in Bengaluru, Karnataka. The solid oxide electrolyser developed at HPCL’s Green R&D Centre is part of their efforts to advance green hydrogen production.
WEVO-CHEMIE GmbH has introduced new materials applied as liquid sealants and adhesives for automated production of alkaline, AEM, and PEM electrolyser stacks, significantly speeding up the process compared to manual assembly. These materials offer high chemical resistance, low hydrogen permeation, and good adhesion.
In a novel study, researchers at the University of Twente have made significant strides in understanding the behaviour of micro- and nanobubbles on electrodes during water electrolysis, a process crucial for green hydrogen production. These tiny bubbles form on the electrodes, blocking the flow of electricity and reducing the efficiency of the reaction.
GAIL (India) Limited, India’s largest natural gas company, has inaugurated its first green hydrogen production plant in Vijaipur, Madhya Pradesh, as part of the National Green Hydrogen Mission. This initiative by the Government of India promotes the development and adoption of green hydrogen technologies across the country.
