REMONT, CA/AMSTERDAM — Green hydrogen developer Ohmium International, which deploys Proton Exchange Membrane (PEM) electrolyzers, has formed a collaboration with Aquastill, a specialist in modular membrane distillation technology that uses energy from waste heat for desalination.
Ohmium plans to use the latter’s desalination capabilities to produce suitable seawater for green hydrogen production.
The duo foresees decarbonization opportunities for businesses operating in coastal areas by providing a more efficient and affordable way of producing clean energy. According to Ohmium, integration of modular desalination units will facilitate new applications for cost-effective green hydrogen production, including co-locating PEM electrolyzers with offshore wind farms, enabling green hydrogen production at source.
They have begun assessing how best to integrate their technologies.
Aquastill’s process is powered by the residual heat from Ohmium’s electrolyzers, and the membrane distillation process simultaneously provides additional cooling for the electrolyzer.
Unlike other energy-intensive desalination technologies, the company added, the waste heat for the membrane-based distillation process has minimal energy requirements. And the compact design of the desalination modules makes them straightforward to transport wherever clean water is needed.
