Swansea and Grenoble experts have teamed up to create a realistic method for producing green hydrogen using sustainable catalysts.
The experts now anticipate that their study will be a significant step in making green hydrogen production more simple, cheap, and scalable.
The group has now developed engineered solvents that allow hydrogenases to act in air. Simply soaking them in these solvents instead of water makes them more active and stable, allowing them to be utilized to create hydrogen in the air.
Swansea University’s expertise in photocatalysis, solvent design, and its emphasis on providing practical solutions to complex problems were coupled with knowledge of retrieving natural enzymes and using them for renewable energy conversion at the Alternative Energies and Atomic Energy Commission (CEA) and Université Grenoble Alpes (UGA).
Swansea’s strategic connection with UGA resulted in the collaboration. The findings were published in the international journal Angewandte Chemie.
Green hydrogen is required as a fuel for the decarbonization of transportation, particularly long-haul aviation, HGV, the marine sector where electrification is not feasible, as well as the chemical industry, particularly fertilizer manufacture, and the energy sector.
However, the costs of manufacturing green hydrogen currently prevent its widespread usage, which is why this discovery is so important for the future.
Utilizing sustainable catalysts like hydrogenases instead of costly platinum can reduce the cost of electrolyzers and fuel cells, making green hydrogen more affordable to create and utilize. It also reduces reliance on imports, which can be disrupted by outside forces.
