Ohmium International, a green H₂ company that designs, manufactures and deploys advanced proton exchange membrane (PEM) electrolyzer solutions, announced that it signed a term sheet with SwitcH2 BV, a renewable energy joint venture with partners such as BW Offshore, a leading provider of offshore production solutions. Under the agreement, Ohmium will develop PEM electrolyzer solutions for a pioneering 300-MW offshore floating green H₂ and ammonia synthesis project led by SwitcH2.

Located off the coast of Southern Europe, the project will create an industrial scale floating green H₂ and ammonia production facility based on proven floating production, storage and offloading (FPSO) technologies. 300 MW of Ohmium’s PEM electrolyzer solutions will be installed on board SwitcH2’s 268-meter FPSO vessel. When complete, the 300MW floating facility will have an annual production capacity of up to 55,000 tons of green H₂ and almost 300 kton of green ammonia – enough to fuel multiple oceangoing vessels for a full year.

Ohmium's PEM electrolyzers will utilize nearshore solar and wind power, along with treated seawater, to produce green H₂. The H₂ will be fed into an on-deck ammonia synthesis unit, and the resulting product will eventually be offloaded onto an ammonia carrier for transport to offtakers. With support from the Dutch government and approval in principle for its design by the Norwegian certification agency DNV, the project anticipates green ammonia production by 2029.

“We are pleased to have Ohmium join us in making this pioneering project possible,” said SWITCH2’s director and co-founder Bob Rietveldt. “Ohmium’s compact, hyper modular PEM electrolyzers are ideally suited for the space constrained FPSO setting. Their product delivers high efficiency, and the comprehensive, standardized design enables flexible and rapid installation, at scale.” 

“Ohmium is thrilled to be part of this cutting edge and transformative project,” said Arne Ballantine, Ohmium CEO. “We appreciate the expertise that SwitcH2 Joint Venture brings to offshore floating production, and their vision in leveraging renewables and green H₂ for the creation of green ammonia. The market for green ammonia is poised to grow exponentially in the coming decades, especially as a source of clean fuel for the global shipping industry, and Ohmium is looking forward to collaborating with SwitcH2 in helping address that need.”
