During the Games in Paris, 10 fuel cell buses will transport visitors emission-free alongside 300 cars with fuel cells. This was criticized by 120 researchers, academics and engineers in an open letter that has been circulating in the media. https://lnkd.in/ek4rVyh2.

The cars require three times as much renewable electricity as battery-powered electric vehicles, and the majority of hydrogen is currently produced from fossil fuels, they say. Valid arguments? The latter is correct, green hydrogen is still far from being available in sufficient quantities. This must change, and many people are working on this in many places. However, there is also a lack of renewable electricity, especially in France. And what about the consumption of fuel cell vehicles? “Three times as much electricity” is a bit of an exaggeration, 2.3 times as much is correct, see https://lnkd.in/esbrSfGe And: the production of green hydrogen consumes a lot of renewable energy, but if H2 and eFuels are produced in regions in the future where abundant solar and wind energy would otherwise remain unused, efficiency hardly plays a role.
