Researchers at Brunel University of London, in collaboration with the company Genuine H2, have developed a technology to convert seawater into hydrogen fuel to power ships and other forms of transport, aiming to eliminate diesel use and reduce carbon emissions. The process involves splitting seawater using renewable electricity to produce hydrogen gas, which is then stored onboard ships as a molecular solid and burned in engines that emit only steam, thus providing a clean energy alternative. This innovation includes carbon-negative electrolysis units that also extract CO2 from water to create bicarbonates, contributing to a circular and environmentally friendly energy cycle. The technology is scalable and versatile, capable of fueling various transport modes such as yachts, ferries, airplanes, trains, and trucks, as well as supporting infrastructure like hydrogen refueling stations for both land and marine applications. A key breakthrough includes electrodes that extract hydrogen directly from seawater without the need for desalination, and a nano film that safely stores hydrogen at room temperature without requiring heavy pressurized tanks.
