Low carbon hydrogen production is the key to reducing its CO2 emissions. The electrolysis of water for hydrogen production links the CO2 emissions from the power system with those from hydrogen production. This article incorporates the power system into a hydrogen production Integrated MARKAL-EFOM system model and predicts the impact of hydrogen production methods and power structure on CO2 emissions from hydrogen production in China. The results show that: Under the business as usual scenario, the CO2 emissions from hydrogen production are projected to decline in 2045 and then rebound in 2050. It indicates that the current power structure is difficult to support the further reduction of hidden CO2 emissions in the future electrolysis of water for hydrogen production. Hydrogen production technologies optimization has a greater effect on CO2 emissions reduction in hydrogen production, its effect will gradually weaken, whereas the emission reduction effect of power structure optimization will gradually strengthen. The information presented in this paper could be helpful for researchers and policymakers to correctly consider the coupling relationship between power system and hydrogen system in the long-term energy transformation process.
