ACWA Power, a leading developer, investor, and operator of power generation, water desalination, and green hydrogen plants worldwide, has signed a Memorandum of Understanding with Nanostone Water Inc., a global membrane solutions company, to perform R&D and knowledge transfer at the King Abdullah University of Science and Technology (KAUST), the leading innovation hub in Saudi Arabia, to evaluate Nanostone’s UF ceramic membranes and process technology in seawater desalination applications.


The collaboration between ACWA Power, Nanostone Water Inc. and KAUST further positions Saudi Arabia as a technological and innovation hub in frontier applications for sustainable power, water desalination and green hydrogen, globally. The new partnership pursues applied industry-oriented research to develop a robust pretreatment process for seawater desalination applications with superior protection and an extended lifetime for downstream reverse osmosis membranes.

Thomas Altmann, Executive Vice President of Innovation and New Technology at ACWA Power, and Christian Goebbert, Managing Director, Chief Scientific Officer, and Vice President of Research and Development at Nanostone Water Inc., signed the agreement during the European Desalination Society (EDS) conference in Cyprus. ACWA Power, being a Titanium sponsor, actively supported the conference’s mission of promoting “Desalination for the Environment, Clean Water, and Energy.”
