The production of degradable polyglycolic acid from coal is a promising route for converting coal to high-end chemicals and can availably alleviate the problem of excess ethylene glycol. However, the traditional coal-to-polyglycolic acid (CtPGA) process wastes a lot of precious CO gases to adjust the H 2 /CO ratio, simultaneously producing a large amount of CO 2 emissions. To address this issue, this work proposes a novel coal-to-polyglycolic acid process integrated with green hydrogen from complementary wind and solar power (GHCtPGA). The complementary characteristics of solar and wind energy are investigated to generate green hydrogen. It is found that the hybrid power of wind−solar energy for the green hydrogen production process can significantly affect the capacity of the energy and hydrogen storage systems. After the modeling and simulation of the whole flowsheet of the CtPGA and GHCtPGA processes, the techno-economic and environmental performance of these processes is analyzed in detail. Compared with the CtPGA process, the GHCtPGA process reduces CO 2 emissions by 68.85% and improves carbon and exergy efficiencies by 11.57 and 2.72%, respectively. Furthermore, the economic performance of the GHCtPGA process is more satisfactory because its total capital investment is reduced by 11.32%, the total production cost is saved by 3.59%, and the internal rate of return is improved by 2.83%. Finally, a sensitivity analysis is conducted to explore the effect of coal price, electricity price, power consumption, and carbon tax on the economic advantages of the proposed GHCtPGA process. It indicates that the proposed GHCtPGA process has considerably stronger market risk resistance than the CtPGA process. Therefore, the proposed process provides a valuable PGA production route with low carbon, high efficiencies, and optimal economic trade-offs.
