Abstract
An energy generation plant in which the exhaust gas from a gas turbine is guided into a thermal energy store, wherein the thermal energy store can be used for various purposes. The energy generation plant has at least one gas turbine having an exhaust gas apparatus, at least one generator, at least one thermal energy store, wherein the generator can be driven by the gas turbine, wherein the hot exhaust gas from the gas turbine is passed directly to a thermal energy store via the exhaust gas apparatus, wherein the thermal energy from the thermal energy store can be used to generate power.

1-23. (canceled)
An energy generation plant, comprising:
- a gas turbine comprising an exhaust gas apparatus,
- a generator,
- a thermal energy store,
- wherein the generator is adapted to be driven by the gas turbine,
- wherein hot exhaust gas from the gas turbine is adapted to be passed directly to the thermal energy store via the exhaust gas apparatus,
- a power generating apparatus for using thermal energy from the thermal energy store to generate power, and
- a fan,
- wherein the thermal energy store is discharged via the fan which supplies cold air to the energy store via a supply line in such a manner that hot air is pushed from the thermal energy store, and
- wherein the hot air leaving the thermal energy store is selectively mixable with a controllable mass flow of cold air which is also supplied by the fan via a bypass line that bypasses the thermal energy store.
A method for operating an energy generation plant, at least comprising a gas turbine comprising an exhaust gas apparatus, a generator, and a thermal energy store, the method comprising:
- driving the generator by the gas turbine,
- guiding hot exhaust gas from the gas turbine via the exhaust gas apparatus directly into the thermal energy store,
- using only the hot exhaust gas from the gas turbine to heat the thermal energy store, and
- using thermal energy from the thermal energy store at least to generate power via a power generating apparatus,
- wherein the thermal energy store is discharged using a fan which pushes hot air from the thermal energy store, and
- wherein the hot air leaving the thermal energy store is selectively mixable with a controllable mass flow of cold air which is also supplied by the fan via a bypass line that bypasses the thermal energy store.
