In transport: as a climate-neutral energy source, e.g. in heavy goods transport or rail and shipping), but also in individual transport. The combustion engine becomes a fuel cell drive. The advantage of the fuel cell is that water comes out of the exhaust and not climate-damaging gas! The transition of technologies will be gentle. By the way: E-fuels (synthetic paraffin, for example) are also produced from green hydrogen and can power aircraft or other engines in a climate-neutral way. In industry: in the production of green steel (e.g. for sheet metal for cars, scooters, etc.), green cement or green aluminium. This provides a boost to innovation and maintains and creates new jobs. Thanks to green hydrogen, we can keep our energy-intensive industries in Germany!
