The current trend in the automotive industry shows a shift away from drive concepts with gasoline and diesel combustion engines toward lower-emission alternatives.

On the one hand, vehicles with electric drives and batteries for storing energy in electrical form have become established. On the other hand, the market is dominated by vehicles that derive their drive energy from hydrogen.

Electric drive systems powered by batteries are highly efficient. The electricity required is generated sustainably (e.g., by photovoltaic or wind power plants) and stored directly in the electric car’s batteries via a charging station. From there, it is directly available to the electric motors that power the vehicle.

On the other hand, the long charging time for electric vehicles is problematic. Combined with their comparatively short range, this severely limits the suitability of electric vehicles for long-distance travel. The extraction of raw materials for battery production also has a significant impact on the environment.

Even in hydrogen-powered vehicles, the extraction of raw materials for the production of components such as tanks and fuel cells is not without its problems. Producing the carbon fiber tank and fuel cell generates about as much greenhouse gas as the production of a medium-sized electric car battery.

Hydrogen-powered vehicles, on the other hand, offer the same advantages as vehicles with combustion engines. Their long range and short refueling times make them suitable for long-distance travel.
