"Heavy-duty road vehicles Hydrogen fuel cells or hydrogen-derived fuels offer a low-carbon alternative for heavy-duty vehicles, for which batteries do not currently have the energy density to offer a long-range solution. " "One niche market for hydrogen fuel cells is forklift trucks. These currently outnumber hydrogen cars, with around 30,000 in use. Fuel cell forklifts are suited to warehouse use because refuelling is simple, and the vehicles emit no air pollutants32" "Synthetic fuels. A range of synthetic fuels for multiple uses can be made via the Fischer Tropsch process, reacting captured CO2 with hydrogen. These could potentially provide a lower carbon drop-in fuel alternative for the aviation fleet as well as an option for trucks or ships" "Ammonia is denser and only requires compression to 10 times atmospheric pressure or chilling to -33°C6 . Ammonia storage is mature because of its widespread use as a feedstock for mineral fertilisers. " "For transport, China is aiming to produce one million hydrogen fuelled vehicles and 1,000 refuelling stations by 2030, the same goals as California3, 55. South Korea’s roadmap is aiming to produce six million FCEVs and roll out 1,200 refilling stations by 2040."
