Gas storage
Our energy supply is also based on the constant availability of natural gas. As the lowest-emission fossil fuel, it is used in many ways: primarily for heating but also as a fossil fuel to generate electricity in gas-fired power plants, or as an environmentally friendly fuel on our roads. The gas supply in Germany is secured by a variety of supply sources, long-term gas supply contracts, and secure transport routes as well as gas reserves stored in natural gas storage facilities. They serve to cover consumption peaks and compensate for seasonal fluctuations in consumption. In 2012, at the Etzel site, we commissioned a natural gas storage facility with two caverns.
