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

摘要

The concept of complementary decarbonisation of power generation from renewable energy sources and fossil fuels consists of their integration in one system. A technology network in the form of a CCU-combined power plant is proposed for the energy generation from fossil fuels by a coal power plant with CO2 recovery from the exhaust gases and a pyrolysis of natural gas to hydrogen and carbon as a basic technology. This technology network is completed by a reverse water-gas shift reaction for the conversion of the CO2 to CO, which will react with the hydrogen in a Fischer-Tropsch synthesis for synthetic diesel. The recovered energy from the exothermic Fischer-Tropsch synthesis meets the energy needs of CO2 scrubbing. The carbon from the pyrolysis can replace other fossil carbon or can be sequestered.
