Electrolyzer

The renewables-powered sustainable hydrogen announcements have come as a group of international researchers made controversial claims about the potential of gas-fired blue hydrogen to be part of the climate change solution.

TotalEnergies wants to decarbonize hydrogen production in Normandy with the support of Air Liquide and, in Chile, an international consortium has begun construction of the country’s first green hydrogen facility. Elsewhere, the Indian government has invited U.S. companies to bid for green hydrogen and electrolyzer contracts.

Enertrage and Sunfire want to build an electrolysis test field in eastern Germany and Hyzon Motors sold 500 hydrogen-powered electric trucks to Shanghai Hydrogen HongYun Automotive. Moreover, several partnership agreements were announced in Malaysia, Japan, the US, Australia and South Korea.

Moreover, two big Russian corporations have unveiled plans to produce hydrogen and Portuguese utility EDP said it wants to set up a a pilot project for a green hydrogen plant in Brazil.

H2 Energy Europe is building a power-to-gas project in Denmark and Everfuel wants to put hydrogen refueling stations in Sweden. Chinese energy giant Sinopec said it wants to invest massively in hydrogen and the Australian Energy Market Operator (AEMO) has said hydrogen will be the main driver for “very quick” growth in electricity demand.

Furthermore, the Indian government is proposing to mandate using green hydrogen in fertilizer and refining and Japanese automotive manufacturer Toyota wants to assemble integrated dual fuel cell (FC) modules in the United States.

A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolyzers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.

Spanish energy giant Iberdrola will lead a consortium that plans to convert the Apennine railway axis in central Italy to green hydrogen. Ukrainian energy company NJSC Naftogaz has said it wants to produce green hydrogen with a German partner, and the Port of Tallinn, in Estonia, wants to become a hydrogen hub.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.

ThyssenKrupp has also said it is working on a green hydrogen and ammonia project in the Emirates and three U.S. companies are planning to develop low-cost renewable hydrogen generation for use in transportation and distributed energy applications.
