ENERGY SUPPLY SYSTEM AND OPERATING METHOD

摘要

According to the invention, the energy supply system comprises a current generating device (1) for regeneratively generating electricity which can be fed into a power supply network (2), a hydrogen generating device (3) for generating hydrogen using electricity from the regenerative current generating device, a methanation device (4) for converting hydrogen generated by the hydrogen generating device and a fed carbon oxide gas into a gas containing methane, and a gas providing device (11) for providing an additional gas or an exchange gas at a variably specifiable additional/exchange gas quality suitable for feeding into a gas supply network using the gas containing methane from the methanation device and/or using the hydrogen from the hydrogen generating device. The energy supply system can be used in large-scale energy supply networks, for example.
