Sweetch Energy proposes to produce electricity from desalination of sea water. The most concentrated salt solutions are recovered by a filtration system and transformed into electrical energy. This disruptive innovation is expected to reduce the current cost of desalination by 25%, currently $3/m3.
Winner of the global innovation competition, the company is accompanied by the Go Capital Amorage II and Emertec funds which have invested €1.4 M and a loan and a grant from Bpifrance (€700 k). This will help them to develop the tools to create an initial pilot within two years.
Sweetch Energy has also opened a test laboratory in Rennes in the Biopôle spaces to test its technology. Its favourable cost will enable it to address new global markets, including the agricultural sector. The Sweetch Energy machine will be able to produce 100 W of electricity/m² of filtration membrane. B. Mottet, its leader, plans to carry out a second fundraiser for the industrialisation phase. His patent comes from a CNRS technology transfer that he plans to expand to river water.
