Abstract: This study proposes a novel hybrid solar-gas power and hydrogen-production (SGPH) system, which is comprised by the parabolic trough solar thermal system, gas-steam turbine combined cycle (GTCC) and organic Rankine cycle-based hydrogen-production system. Based on the Ebsilon code, the operation processes of the SGPH system are simulated. The results show that the output power and electric efficiency of the SGPH system are 102.0 MW and 44.2%, and the daily hydrogen output is 172.4 kg. The annual operation simulation results reveal that the GTCC and solar island can both achieve stable operations, and the power generation section and hydrogen-production device can both work effectively, which means the SGPH system can follow the pre-set operation strategy. According to the economic analysis results, the levelized electricity costs of the SGPH system with and without considering the subsidy are 0.052 $/kWh and 0.077 $/kWh, and the levelized hydrogen cost of the SGPH system is 5.72 $/kg, which reveal a relatively good economic competitiveness. The pollutant emission reduction analysis results show that compared with a coal-fired power system, the SGPH system can reduce the emission quantities of CO2, NOx, SO2 and dust by 103022.9 t, 3343.6 t, 3161.2 t and 1724.8 t every year.
