Adding electrical components to high-performance drive and propulsion systems – as is the case with hybridized rail traction and marine propulsion – makes them greener. In a hybrid system, diesel or gas engines are combined with electric motors, storage batteries and power electronics. This ensures low emissions, lower fuel consumption and excellent and flexible drive performance.
In power systems, the use of storage batteries allows greater use of renewable energy sources, thereby enabling higher power grid stability and lower CO2 emissions. Fuel cells carry huge potential as a key technology for decarbonizing drive and energy systems. And fuel cells fed with green hydrogen made from renewable sources are set to play an even more significant role in the energy transition.
