PEM (Proton Exchange Membrane) electrolyzer manufacturer, Ohmium International announced it has entered a strategic collaboration with the Netherlands based Aquastill BV, to produce green hydrogen using desalinated seawater.

Aquastill provides modular membrane distillation technology using the power of waste heat for desalination.

"This strategic collaboration is a great example of how the innovative integration of Ohmium and Aquastill's technologies can enable the expansion of green hydrogen production to new sectors and geographies," said Arne Ballantine, CEO of Ohmium International.

"Utilizing Aquastill's membrane technology to efficiently produce green hydrogen from seawater has the potential to be a game changer for companies operating in coastal or rural regions that want to affordably and sustainably decarbonize."

By integrating Aquastill's desalination capabilities with Ohmium's modular green hydrogen electrolyzers the two companies intend to create new decarbonization opportunities for businesses operating in coastal areas by providing a more efficient, sustainable, and affordable way of producing clean energy.

Ohmium and Aquastill have started assessing optimal integration of these technologies and are working on making these fine-tuned modules commercially available as soon as possible.

The novel method of integration of modular desalination units in electrolyzers will facilitate new applications for cost-effective green hydrogen production, including co-locating PEM electrolyzers with offshore wind farms, enabling the production of green hydrogen at-source.

The advanced desalination modules feature a modular and compact system design, making them easily transportable to wherever clean water is needed.

Further, unlike other energy intensive desalination technologies, the waste heat membrane-based distillation process has minimal energy requirements.

"We have already begun to test the integration of our respective technologies, and we are confident that as a result of this joint collaboration we will be able to produce cost-competitive green hydrogen from seawater, while simultaneously helping decarbonize the operations of companies operating in coastal regions," said Bart Nelemans, CEO of Aquastill.
