Ohmium International, a leader in green hydrogen technology, has signed a Term Sheet with SwitcH2 BV, a renewable energy joint venture that includes BW Offshore, a major provider of offshore production solutions. Ohmium will supply its Proton Exchange Membrane (PEM) electrolyzer solutions for a groundbreaking 300MW offshore floating green hydrogen and ammonia project spearheaded by SwitcH2.
The facility, located off Southern Europe’s coast, will be an industrial-scale floating green hydrogen and ammonia production platform, utilizing Floating Production, Storage, and Offloading (FPSO) technology. Ohmium’s 300MW PEM electrolyzers will be installed on SwitcH2’s 268-meter FPSO vessel, capable of producing up to 55,000 tonnes of green hydrogen and nearly 300,000 tonnes of green ammonia annually—enough to fuel multiple oceangoing vessels for a year.
Powered by nearshore solar and wind energy, the electrolyzers will use treated seawater to produce hydrogen, which will feed into an onboard ammonia synthesis unit. The green ammonia produced will then be transported to offtakers via ammonia carriers. The project, supported by the Dutch government and approved by Norwegian certification agency DNV, is set to begin production by 2029.
SwitcH2 director and co-founder Bob Rietveldt praised Ohmium’s compact and modular PEM electrolyzers, ideal for the space-limited FPSO setup, highlighting their high efficiency and rapid scalability. Ohmium CEO Arne Ballantine expressed enthusiasm for collaborating on this innovative project, emphasizing the growing demand for green ammonia as a clean fuel for the global shipping industry.
Ohmium, headquartered in the U.S. with manufacturing in India and global operations, designs scalable PEM electrolyzers for cost-effective green hydrogen production. The company has a green hydrogen project pipeline exceeding 2 GW across three continents. In 2023, Ohmium raised $250 million in Series C funding led by TPG Rise Climate.
