Abstract: Remote areas in China are generally rich in renewables, but poor in supports from stables power grid, forming power supply systems with renewables as the mainstay, diesel generators as the auxiliary. The commitment of “carbon peaking and carbon neutral” necessitates to transform power supply from fossil-dominated to renewable-centered non-emission one. To replace diesel generators with high fuel cost and serious environmental pollution, in this paper we propose a technical solution to construct a zero-carbon microgrid based on hydrogen storage in renewable-rich remote areas. To do it, we first investigate the resource endowment in renewable-rich remote areas to analyze the constructing potential of hydrogen-based zero-carbon microgrids. Then we design the system framework by proposing capacity planning principles based on renewable resource endowment and reasonable operation strategies. A village in Yunnan Province is taken as a case to verify its operational reliability and economic feasibility. We also discuss its potential use as CCHP to further reduce regional carbon emission. The work reported here show-cases a viable pathway of decarbonizing microgrid based on hydrogen for regions with similar resource endowment.
