Outline
This paper takes GE 9HA.02 combined cycle unit as the research object, and innovatively proposes the design scheme of a hydrogen natural gas mixing integrated system in gas turbine power plant, with gas hydrogen long tube trailers as the main hydrogen transmission method and reserved pipeline gas inlet interface. Through the configuration of a hydrogen compressor bypass system, the residual hydrogen stored in the long tube trailer was fully utilized, improving the utilization rate of trailer hydrogen storage. At the same time, a comparative analysis was conducted on the economic feasibility of adding hydrogen to the 9H class gas turbine power plant. Electricity price and natural gas price are more sensitive to the impact on the internal earing rate of return. And in order to meet the requirements, hydrogen price cannot exceed 38.5 yuan/kg. With the development of renewable hydrogen production technology, and driving the further reduction of hydrogen production costs, the promotion and application of hydrogennatural gas mixing integrated system will become increasingly competitive.
