Abstract:

Multi-energy coupled process linear programming models integrating carbon footprint tracking was established, assessing the overall performance and carbon footprint of multi-energy-coupled refining processes that integrate wind energy, solar energy, biomass, natural gas, and coal-to-hydrogen process. The results indicate that coupling low-carbon energy hydrogen production processes can significantly reduce the carbon footprint of refining products. Among them, the hydrogen production process coupled with solar energy has the best emission reduction effect, with the gasoline carbon footprint(calculated by CO₂) reduced to 377.07 kg/t, a reduction of about 30% compared to traditional processes. However, due to the high cost of obtaining low-carbon hydrogen, the overall profits of the three schemes with multi-energy coupled low-carbon hydrogen sources are 9% to 22% lower than traditional energy hydrogen production processes. With the introduction of carbon taxes, the low-carbon advantages of renewable energy gradually become evident. As the costs of wind power generation and photovoltaic power generation technologies decrease, multi-energy-coupled processes will demonstrate competitiveness in terms of economic and environmental performance.
