Green hydrogen combustion for power generation is an effective path to achieve carbon neutrality in new-type power system. This article first discusses the rationale for green hydrogen combustion power generation from the perspective of increasing renewable energy curtailment and the necessity of long-term energy storage. It then analyzes the economy of green hydrogen combustion for power generation, including the technology's own economic feasibility and comparisons with other energy storage routes. Finally, elaborate on the expected development path and technical difficulties of the green hydrogen combustion power generation technology route.
