Presentation
The FuelSea project seeks to revolutionize the nature of electrode coatings for the production of energy (H2) or chlorinated disinfectants. Currently used raw materials are critical and it is essential to reduce their quantity and use more abundant metals.
The FuelSea technology has enabled the implementation of a manufacturing process for composite materials for the coating of electrodes. This bio-inspired coating contains sub-nanometer sized metal particles with active surfaces enabling higher mass activity than existing technologies. Moreover, this technology allows us to diversify the nature of catalysts by using abundant transition metals.
Uses
- Electrochlorination for the disinfection of swimming pool water
- Production of decarbonated hydrogen by electrolysis of (sea) water
- Production of chlorine by chlor-alkali process
