生物天然气绿色价值实践路径分析与展望OA

Against the backdrop of China's"Dual Carbon"goals and global energy transition,biomethane has evolved into a vital component of the renewable energy system owing to its advantages including life-cycle low or negative carbon emis-sions,abundant feedstock sources,and high compatibility with existing energy infrastructure.Nevertheless,excessive capital investment and an immature industrial chain impede the market-oriented monetization of its environmental benefits,which stands as the core bottleneck restricting the large-scale development of the biomethane sector.This paper comparatively ana-lyzes diversified exploitation approaches for the green value of biomethane and identifies feasible development pathways to advance its marketization in China.The research reveals that,compared with the conventional project-based carbon asset de-velopment model,establishing a product-oriented green benefit system anchored in carbon footprint accounting,endorsed by green certification and carried via tradable biomethane certificates can effectively embed emission reduction gains into the intrinsic physical value of biomethane products.Such a framework delivers incentivization to all upstream and downstream participants across the industrial chain,facilitates a more sustainable low-carbon transition route,and offers institutional ref-erences for improving the market-based mechanism of China's biomethane industry.
