Combined Decarbonization of Electrical Energy Generation and Production of Synthetic Fuels by Renewable Energies and Fossil Fuels

Power generation from renewable energy sources and fossil fuels are integrated into one system. A combination of technologies in the form of a carbon capture utilization (CCU)‐combined power station is proposed. The technology is based on energy generation from fossil fuels by a coal power plant with CO2 recovery from exhaust gases, and pyrolysis of natural gas to hydrogen and carbon, completed by reverse water‐gas shift for the conversion of CO2 to CO, which will react with hydrogen in a Fischer‐Tropsch synthesis for synthetic diesel. The carbon from the pyrolysis can replace other fossil carbon or can be sequestered. This technology offers significant CO2 savings compared to the current state of technology and makes an environmentally friendly use of fossil fuels for electricity and fuel sectors possible. The idea is to interconnect energy generation from renewable energies (RE) with fossil energy from stations with low CO2 footprints. These stations are capable of both base load operation and compensation for RE volatility and would produce both electricity and fuel, resulting in an improved overall efficiency from the combined energy production mix. The concept has a high degree of flexibility.
