Biomass energy is a clean and environmentally friendly renewable energy source, and the transition to biomass is driven by both environmental goals (carbon neutrality) and the feasibility based on biomass availability. This paper develops a new model to assess the feasibility of using biomass as a coal substitute for heating rural buildings. To assess the feasibility of this model, a case study was conducted in China's Heilongjiang province. We collected data on crop straw availability from 2005 to 2020 and analyzed coal consumption and carbon dioxide emissions in rural building heating from 2011 to 2020. Considering China's carbon neutral targets, we further assessed changes in coal consumption, biomass straw demand, carbon dioxide emissions, and pollutant emissions resulting from the adoption of biomass for heating in rural areas between 2021 and 2060. The findings reveal that coal consumption and carbon dioxide emissions displayed fluctuating patterns in the past decade, averaging around 550,000 tons and 1,050,000 tons, respectively. The use of biomass straw resulted in a gradual decline in carbon dioxide emissions, reaching near-zero levels, and also effectively reduced SO, NO and PM by 91.6 %, 49.3 % and 8.3 % respectively. The demand for biomass as an alternative to coal is up to 0.84 % of the currently available biomass, and there is enough biomass available. These findings emphasize the feasibility of biomass straw to achieve carbon neutrality in Heilongjiang Province and can guide policy makers, researchers and stakeholders in developing and implementing effective strategies for sustainable energy systems.
生物质能是一种清洁环保的可再生能源，向生物质的转型受到环境目标（碳中和）和基于生物质可得性的可行性的双重驱动。本文开发了一种新模型，以评估使用生物质替代煤炭为农村建筑供暖的可行性。为评估该模型的可行性，在中国黑龙江省进行了案例研究。我们收集了2005年至2020年作物秸秆可得性的数据，并分析了2011年至2020年农村建筑供暖中的煤炭消耗和二氧化碳排放。考虑到中国的碳中和目标，我们进一步评估了2021年至2060年农村地区采用生物质供暖导致的煤炭消耗、生物质秸秆需求、二氧化碳排放和污染物排放的变化。研究结果表明，在过去十年中，煤炭消耗和二氧化碳排放呈现波动模式，平均分别约为55万吨和105万吨。生物质秸秆的使用使二氧化碳排放逐渐下降，达到接近零的水平，还分别有效减少了91.6%的二氧化硫、49.3%的氮氧化物和8.3%的颗粒物。作为煤炭替代品的生物质需求高达目前可得生物质的0.84%，且有足够的生物质可用。这些研究结果强调了生物质秸秆在黑龙江省实现碳中和的可行性，并可为政策制定者、研究人员和利益相关者制定和实施可持续能源系统的有效战略提供指导。
