📄 Abstract（原文）

Hydrogen is a core low-carbon energy vector for China’s dual carbon goals, yet mainstream fossil-based gray hydrogen has inherent high carbon intensity, complementary carbon capture, utilization, and storage (CCUS) systems significantly increase the complexity of hydrogen production systems, while traditional biomass-based hydrogen production methods face bottlenecks in the form of low conversion efficiency and high costs, creating an urgent demand for innovative low-carbon, high-efficiency, low-cost large-scale hydrogen production technologies. To address these challenges, this work proposes a novel solar-driven biomass-methane co-gasification hydrogen production system integrated with an in-situ palladium membrane hydrogen separation unit, realizing the first full-process synergistic coupling of solar-driven co-gasification, in-situ membrane separation, and direct off-gas valorization for heavy oil thermal recovery. This system can produce high-purity hydrogen, while simultaneously generating a by-product stream of high-temperature, high-pressure CO2 steam that can be directly utilized for heavy oil thermal recovery, achieving full byproduct valorization and in-situ CO2 geological sequestration without additional CCUS units. The performance of each subsystem under various operating parameters were first analyzed. Subsequently, the effects of key parameters, including pressure and feedstock ratio, on hydrogen yield and overall energy conversion efficiency were investigated to determine the optimal operating conditions. Under these optimized conditions, the system achieves a renewable energy utilization ratio of 34.7% and an energy conversion efficiency of 59.9%. This system shows promising engineering potential in regions with abundant solar, biomass and heavy oil resources, providing critical theoretical and technical support for low-carbon hydrogen industry transition and green upgrading of fossil energy development.
