Ohmium International has signed a term sheet with SwitcH2 to develop electrolysers for a 300MW floating offshore hydrogen and ammonia synthesis project.
Located off the coast of Southern Europe, SwitcH2’s power-to-X project will create an industrial scale floating green hydrogen and ammonia production facility based on proven floating production, storage and offloading (FPSO) systems.
The PEM electrolyser, using Ohmium’s technology, will be installed on board SwitcH2’s 268 metre FPSO vessel.
SwitcH2 is a project development company, engineering and operating the next generation of offshore floating production systems for the delivery of green hydrogen and green ammonia for industrial offtakers.
It is jointly owned by BW Offshore and Dutch Oceans Capital.
When complete, the 300MW floating facility will have an annual production capacity of up to 55,000 tonnes of green hydrogen and almost 300kton of green ammonia – enough to fuel multiple ocean-going vessels for a full year.
The 300MW electrolysers will use nearshore solar and wind power, along with treated seawater, to produce green hydrogen.
The fuel 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, standardized design enables flexible and rapid installation, at scale.”
Ohmium chief executive Arne Ballantine said: “Ohmium is thrilled to be part of this cutting edge and transformative project.
“We appreciate the expertise that SwitcH2 Joint Venture brings to offshore floating production, and their vision in leveraging renewables and green hydrogen 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.”
