Gasification efficiencies for gasifiers are in the range of 75 to 92% (based on Lower Heating Values). So why is the IPFC process so different?
Gasification efficiencies do not reflect the thermal efficiency of producing the electricity and hydrogen products. The gasification efficiencies represent the efficiency for only one component in producing the final products: the gasification component. Said another way, the gasification efficiency only reflects the efficiency of the gasification process. The gasification process converts the fuel feedstock to a gaseous material, which is subsequently used to produce the end products of electricity and hydrogen. Typical thermal efficiencies for producing electricity with the Integrated Gasification Combined Cycle are in the range of 42% to 50%, with a future expectation of improvement to 60%. The 82 to 92% efficiencies calculated for the IPFC are for the final products, which includes the head end Plasma Black Reactor. These are calculated with the Higher Heating Value of the fuels, which results in a lower efficiency than when using the Lower Heating Values stated in the question. It
