RWE has been granted a patent for a method to operate a power plant for generating electrical energy by combusting a carbonaceous combustible. The process involves separating carbon dioxide from the flue gas, converting it into fuel, and using the waste gas thermal energy for various processes. The method includes combusting the fuel in a heat engine, such as a diesel or Otto engine, and delivering the generated electrical energy to consumers.

Power plant method using waste gas for energy generation
The granted patent (Publication Number: US11913360B2) discloses a method for operating a power plant to generate electrical energy by combusting a carbonaceous combustible and separating carbon dioxide from the flue gas. The separated carbon dioxide is then converted into a fuel. The method involves combusting the fuel in a heat engine, such as a diesel engine or an Otto engine, to produce electrical energy for delivery to consumers. The waste gas from the heat engine, containing thermal energy, is utilized in processes like heating combustion air, process medium, drying carbonaceous combustible, and separating carbon dioxide. The waste gas is then mixed with the flue gas, and carbon dioxide is separated from the mixture and converted into fuel.
Furthermore, the method allows for the waste gas to be supplied to the flue gas before utilizing its thermal energy in heating combustion air, process medium, or separating carbon dioxide. The process medium primarily comprises water, and the fuel used in the combustion process includes substances like methanol, methane, and dimethyl ether. The electrical energy generated is delivered to consumers connected to the power plant via a power grid. The operation of the heat engine and the conversion of carbon dioxide into fuel are optimized based on the electrical load in the power grid. Additionally, the heat engine may also include a gas turbine for enhanced efficiency in generating electrical energy.
