Abstract

Hydrogen and electricity are crucial and interdependent energy carriers in China's pursuit of carbon neutrality, suggesting the necessity of utilizing cost-effective low-carbon technologies that facilitate their integrated development. The cost-optimal, provincial level, deployment of low-carbon technologies under this long-term goal remains to be determined. This study employs the REPO model to identify the cost-optimal, low-carbon hydrogen production mixes and the evolution of the integrated power system of China from 2020 to 2050. The integrated planning and operation of hydrogen supply and power systems are explored at the provincial level. The role of high-temperature gas-cooled reactors in this integrated energy system is also analyzed. The results reveal that electrolytic hydrogen would dominate China's hydrogen supply after 2040, with alkaline, proton exchange membrane, and solid oxide electrolyzers produce over 1 Mt of hydrogen in the short term, by 2035, and in 2050. Leveraging the low-carbon heat production of high-temperature gas-cooled reactors in addition to its electricity generation to meet the thermal requirements of solid oxide electrolyzers could boost the output to 4.2 Mt in 2050 and reducing the total system CO2 emissions and costs by 2.28% and 0.05%, respectively. By 2050, the integration of hydrogen supply and power systems also generates up to 2194 TW h of flexible electricity demand by electrolyzers, which raised the renewable energy penetration by 4 percentage points while decreasing the need of flexible natural gas power generations and energy storages. This study is valuable for proposing the analytical framework and performing the provincial-level study of decarbonization of China's integrated hydrogen supply and power system.

中国氢能供应和电力综合系统中低碳技术的发展
在中国追求碳中和的过程中,氢能和电力是相互依存的重要能源载体,这表明有必要利用具有成本效益的低碳技术来促进它们的综合发展。在这一长期目标下,省级低碳技术部署的成本最优化仍有待确定。本研究采用 REPO 模型来确定成本最优的低碳氢气生产组合,以及 2020 年至 2050 年中国综合电力系统的演变。在省级层面探讨了氢气供应和电力系统的综合规划和运行。还分析了高温气冷堆在这一综合能源系统中的作用。研究结果表明,2040 年后,电解氢将主导中国的氢气供应,碱性、质子交换膜和固体氧化物电解槽在短期内、2035 年和 2050 年的氢气产量将超过 100 万吨。在发电的同时,利用高温气冷堆的低碳产热来满足固体氧化物电解槽的热需求,可使产量在 2050 年达到 420 万吨,并使系统的二氧化碳总排放量和成本分别降低 2.28% 和 0.05%。到 2050 年,氢气供应与电力系统的整合还可通过电解槽产生高达 2194 太瓦时的灵活电力需求,从而将可再生能源的渗透率提高 4 个百分点,同时减少对灵活天然气发电和能源储存的需求。本研究对提出中国氢能供需一体化系统脱碳的分析框架和开展省级研究具有重要价值。
