A new generation hydrogen fueled power plant

In this paper we have proposed a novel gas turbine cycle with hydrogen fueled chemical-looping combustion, and the system study on two hydrogen-fueled power plants, the new gas turbine cycle and a advanced gas turbine cycle with H-2/O-2 combustion, has been investigated with the aid of exergy principle (EUD methodology). The hydrogen fueled chemical-looping combustion in the new gas turbine cycle consists of two successive reactions: hydrogen fuel is reacted with metal oxide (reduction of metal oxide), instead of air or pure oxygen, and then the reduced metal is successively oxidized by the air saturated. As a result, the new hydrogen fueled gas turbine cycle has a breakthrough performance, at least about 12 percentage-point higher efficiency compared to the gas turbine cycle with H-2/O-2 combustion, and will be environmentally superior due to complete elimination of NOx formation. The promising results obtained here indicated that this novel gas turbine cycle with hydrogen fueled chemical looping combustion could make a breakthrough in efficient use of hydrogen energy in power plant.
