Hydrogen as an energy store
The problem at hand: renewable energy resources are not as reliable as fossil fuels. The sun doesn’t shine every day, and the intensity of the wind is not always the same. This is why storage facilities are needed so that the surplus power generated when the conditions are good can be stored and distributed later.
According to the Swiss Federal Office of Energy, the most viable storage options are batteries and converting the power into hydrogen, which is easier to store. Unlike batteries, the properties and versatile applications of hydrogen have barely been established. But in our interview, Christian Bach, Automotive Powertrain Technologies expert at EMPA, suggests this technology could make a breakthrough and even go on to play a pivotal role in the energy transition.
