Abstract: This paper investigated the supercritical/transcritical carbon dioxide cycles for water injected hydrogen gas turbine with the advantages of zero carbon emission, low pollution, high efficiency, low cost and so on. This paper selected several typical combined cycles from more than a dozen layouts studied by our team. We constructed a thermodynamic energy and exergy analysis model and verified it with the experimental models from GE. The maximum energy efficiency and its corresponding exergy efficiency that each layout can achieve are obtained after parameter sensitivity analysis, water mixing research and exergy analysis. It can be found that the combined cycle energy efficiency decreases as the water-hydrogen ratio increases. The component with the largest exergy loss is the combustor, accounting for 23.58%. And the transcritical CO2 dual recuperated combined cycle is the best layout with the combined cycle energy efficiency of 64.39% and the combined cycle exergy efficiency of 62.96%. The research done in this paper can provide a basis for the design of next-generation gas turbine.
