Green hydrogen company Ohmium International is to develop PEM electrolysers for a 300 megawatt (MW) offshore floating green hydrogen and ammonia synthesis project led by SwitcH2.
A term sheet was signed with SwitcH2 BV, a renewable energy Joint Venture with partners including BW Offshore.
Located off the coast of Southern Europe, the project will create an industrial scale floating green hydrogen and ammonia production facility based on proven Floating Production, Storage and Offloading (FPSO) technologies.
Ohmium’s PEM electrolysers will be installed on board SwitcH2’s 268m Floating Production Storage and Offloading (FPSO) vessel.
When complete, the floating facility will have an annual production capacity of up to 55,000 tonnes of green hydrogen and almost 300ktonne of green ammonia – enough to fuel multiple oceangoing vessels for a full year.
Ohmium’s PEM electrolysers will use nearshore solar and wind power, along with treated seawater, to produce green hydrogen.
The hydrogen 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 electrolysers are ideally suited for the space constrained FPSO setting. Their product delivers high efficiency, and the comprehensive, standardised design enables flexible and rapid installation, at scale.”
Arne Ballantine, Ohmium CEO, said, “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.”
Ohmium announced European CE mark approval for its Lotus 1.5 electrolyser last month. The CE mark indicates that a product meets the European Union’s stringent safety, health and environmental protection requirements.
