The world’s first hydrogen railway was inaugurated in Germany. The hydrogen trains, produced by the French company Alstom, can reach up to 140 km/h and operate on a route section of about 100 km around Hamburg.
Hydrogen energy is expected to be the key to decarbonisation. Hydrogen can be combined with oxygen to generate electricity or burnt to produce thermal energy. In doing so, it does not emit carbon dioxide. However, not just any hydrogen energy is good enough. It makes no sense to emit carbon dioxide in the process of producing hydrogen itself.
The German hydrogen trains currently use hydrogen supplied by the chemical factory, but it plans to switch to ‘green hydrogen’ in 2024, which is produced by electrolysing water using electricity generated by solar panels and wind turbines.
