Ohmium International announced a strategic collaboration with Aquastill, a company in the space of modular membrane distillation technology that uses the sustainable power of waste heat for desalination. This collaboration will enable Ohmium to use desalinated seawater as an input in green hydrogen production.
By integrating Aquastill’s desalination capabilities with Ohmium’s modular green hydrogen electrolysers, the collaboration will create new decarbonisation opportunities for businesses operating in coastal areas by providing a more efficient, sustainable and affordable way of producing clean energy. In addition, the innovative integration of modular desalination units will facilitate new applications for cost-effective green hydrogen production, including co-locating PEM electrolysers with offshore wind farms, to enable the production of green hydrogen at-source.
Ohmium and Aquastill have begun assessing optimal integration of these technologies, with the intention of having these fine-tuned modules commercially available as soon as possible.
“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. “Utilising 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 decarbonise.”
Aquastill’s technology is powered by the residual heat from Ohmium’s electrolysers and the membrane distillation process simultaneously provides additional cooling capabilities for the electrolyzer. Unlike other energy intensive desalination technologies, the waste heat membrane-based distillation process has minimal energy requirements. These advanced desalination modules feature a modular and compact system design, making them easily transportable to wherever clean water is needed.
In June 2023, Ohmium International announced that its India-based subsidiary has been selected as the PEM electrolyser partner of NTPC Renewable Energy Limited.The agreement is valid for a period of two years till May 2025. Ohmium’s patented electrolysers are expected to be deployed in up to 400 MW of projects across a diverse range of industrial and commercial applications, including ammonia, transportation, and power, among others.
