Storing electricity in the natural gas network may sound somewhat far-fetched, but is in fact an example of forward-looking technology. The idea is to eliminate fluctuations in the supply of wind and solar power.
Conventional power stations that burn gas and coal or use nuclear power provide a continuous supply of electricity and can be switched on or off as demand rises and falls. This is only possible to a limited extent with "green" power from hydroelectric, biomass and geothermal plants, however. Because the availability of wind and solar energy varies, a balancing system is needed to compensate when too much or too little energy is fed into the network.
