In a domestic setting it’s more familiar as a fuel for heating: gas as a primary energy source can be used in many different ways and is considered a viable raw material for the future thanks to its low CO2 emissions during combustion.
It is also used as a heat source for thermal processes in trade and industry, as a fuel for electricity generation, or for motor vehicles and ships. Originally a by-product of petroleum extraction, it is now a convertible energy source throughout Europe.
It didn’t take long to discover its great potential, and gas became a source of energy in itself rather than being simply burned off. This is how natural gas makes a decisive contribution to the energy transition – not only in the electricity sector, but also in mobility and especially in the heating market.
As with many other chemical processes, this is based on combustion of the raw material. The natural gas is ignited under pressure in a turbine, and as it burns it drives the turbine. A connected generator can convert the energy obtained in this way into the end product: electricity.
Gas can also be used as a pure raw material in numerous chemical processes such as the production of fertiliser or hydrogen. Transportation always involves pipelines that are many kilometres in length. However, the liquefied form of the gas – LNG – is transported in huge tankers.
In future, it will be possible to use the existing gas infrastructure to transport biomethane. Technical adaptations will also allow the network to be used to transport hydrogen.
In future, gas-fired power stations will play an increasingly important role in ensuring a reliable, flexible electricity supply as a non-weather-dependent complement to our wind and solar-based electricity generation. The special advantage of these plants lies in the fact that they can be ramped up to their peak power within a few minutes if necessary. This plays an important role in regulating our electricity grids and at the same time prevents power outages during peak demand.
With power plants located in Germany, the Netherlands, the UK and Turkey, RWE is one of the leading operators of state-of-the-art gas-fired power stations in Europe.
