- Flue gas for example an amine scrubber.
- the power plant ⁇ summarizes an electrolysis device for converting the stored carbon dioxide into other substances.
- the power plant comprises a control device for controlling the electrolysis device configured such that the control device obtains current data on the electricity price and if the electricity price undershoots an electricity price threshold, causes the electrolysis device to operate and if the electricity price exceeds the electricity price threshold, the electrolysis device is shut down.
- the force ⁇ factory operates in two mutually exclusive modes, wherein electrical energy is generated from fossil fuel, biomass or biogas in a first operating mode, and carbon dioxide from the power plant produced flue gas is extracted and stored, and wherein in a second operating mode from the stored carbon dioxide Kohlenwas ⁇ serstoffe are generated, for which from outside the
- Power plant supplied electrical energy is used.
- electrical energy is generated from fossil fuel, biomass or biogas and carbon dioxide from flue gas produced in the power plant extracted and saved.

If the price of electricity is below the current ⁇ price threshold, a Weglyseeinrich- tung is operated, and thus converted the stored carbon dioxide in particular in ⁇ substances. If, however, the electricity price exceeds the electricity price threshold, the electrolysis device is shut down and not operated.
- the generation wertvol ⁇ ler substances such as hydrocarbons or other useful products such as CO or alcohols best not take place from the resulting in the motor ⁇ factory carbon dioxide during operation, during which the energy necessary for encryption processing the low-energy carbon dioxide deteriorates the energy balance of the power plant, but advantageously takes place at times when the electrical energy generated by the power plant can not be sold or only with restrictions in terms of cost-effectiveness. Such times are increasingly given by strongly fluctuating electricity prices with temporary Kochan ⁇ bid.
- the means for generating electrical energy from fossil fuel, biomass or biogas are the power plant typical compilations of combustion equipment, so appropriately fed burners together with surrounding facilities such as turbines in which the heat generated in the combustion is converted into a rotational movement.
- the means for generating electrical energy from fossil fuel, biomass or biogas comprise one or more generators which generate electrical voltage from the rotational movement.

This is play as useful for ⁇ if it is in the power plant to a coal power plant, as these are not within a short time can switch between operation and standstill. If the power plant continues to work, the electricity used for the electrolysis can also be taken from the power of the power plant itself.

The oxygen is thus generated in the second operating mode. Switches the gas power plant 10 back into the first mode of operation, in which the operation of the electrolysis ⁇ system 19 is stopped and the gas power plant 10 again works as such, the stored oxygen can be used ⁇ example advantageous for optimizing the combustion of fossil fuel.
- a special operating form for the gas power plant 10 results when the fossil fuel, which is used for the Energyerzeu ⁇ tion, generated by the electrolysis plant 19 and stored in the gas power plant 10.
- the gas power plant 10 for example, natural gas as an energy carrier for the Ver ⁇ incineration, so in this embodiment, the electrolysis plant 19 is designed to produce methane as soon as the gas ⁇ power plant 10 is operating in the second operating mode.

- gas power plant 10 in addition to its power plant function, is a battery, that is, a storage for electrical power. If there is an oversupply of electrical power, typically caused by a high supply of renewable sources, then gas power plant 10 converts this typically cheap electricity using the already stored carbon dioxide in the energy carrier, which is used in the gas power plant 10 for combustion.
