Biomass is present in ample amounts in rural areas, mainly in agriculture residue and animal wastes. Biogas can be produced from rural solid waste, providing affordable clean energy for rural households and a prominent solution to solid waste management. Despite having several benefits of using biogas, the contribution of biogas in rural areas is not as much as expected. Several technical and non-technical barriers are accountable for the slow rate of biogas technology adoption in rural households. Nineteen barriers to household biogas plant adoption in four dimensions of technical, economic, market, and awareness are identified and ranked with the analytical hierarchy process (AHP) in the perspective of rural India. The outcome of the barrier dimension reveals that the economic dimension gets the highest weight of (0.350), followed by the market with a weight of (0.322). At the same time, high installation cost with a weight of (0.141) dominates in the category of barriers, followed by competition from freely available fuel with a weight of 0.105). The gap in capital cost and capital subsidy, lack of paying capacity, and lack of easy credit have positioned respectively third, fourth, and fifth in the overall ranking of barriers with weights of (0.094), (0.084), and (0.08). This paper may contribute significantly to creating greater awareness, evaluating numerous barriers, and adopting biogas technology in India more effectively and efficiently.
生物质在农村地区大量存在，主要存在于农业残留物和动物粪便中。沼气可以由农村固体废物产生，为农村家庭提供负担得起的清洁能源，是解决固体废物管理的突出方案。尽管使用沼气有许多好处，但沼气在农村地区的贡献并不如预期的那么大。一些技术和非技术障碍导致沼气技术在农村家庭中的采用速度缓慢。在印度农村的视角下，通过层次分析法（AHP）确定并对四个维度（技术、经济、市场和意识）的 19 个户用沼气厂采用障碍进行了识别和排名。障碍维度的结果表明，经济维度的权重最高（0.350），其次是市场维度（0.322）。同时，高安装成本（权重为 0.141）在障碍类别中占主导地位，其次是免费燃料的竞争（权重为 0.105）。资本成本和资本补贴之间的差距、缺乏支付能力以及缺乏便捷信贷分别以权重 0.094、0.084 和 0.08 在障碍的整体排名中位列第三、第四和第五。本文可能会对提高认识、评估众多障碍以及更有效地在印度采用沼气技术产生重大影响。
