湖南省农作物秸秆能源化利用现状及对策研究OA

This study systematically reviewed the current status of crop straw utilization for energy generation in Hunan Province,revealing that the total straw utilization volume in this province would reach 24.598 5 million t by 2024.The straw was mainly used as fertilizer and feed,and that utilized for energy generation accounted for only 6.57％.Regarding straw utilization for energy generation,the main technical pathways include biomass power generation,biogas/biomethane production,and densified fuel preparation,which varied among regions.The Dongting Lake region primarily focused on power generation and densified fuel production.Central and Eastern Hunan emphasized densified fuel processing.Southern Hunan adopted diversified models,while Western mountainous areas developed small-scale workshops.Currently,crop straw utilization for energy generation in Hunan faces four major challenges:mismatch between resource distribution and industrial demand,technical bottlenecks,unsound market mechanisms,and poor implementation of related policies.Recommendations included establishing a differentiated collection and storage system,implementing dual-track technology promotion strategies,optimizing full-chain policy coordination,and promoting large-scale and efficient transformation of straw utilization for energy generation.
