Analysis of Yield Potential and Regional Distribution for Bioethanol in China

Bioethanol will play a significant role in energy structure adjustment and greenhouse gas mitigation the future, especially transport sector. As bioethanol production with grain crops may become obsolete due to food security concerns, Chinese government has advocated development of non-grain bioethanol. According current actual situation China’s Liquid Biofuel Development Roadmap, we defined three stages development. We focused on assessment feedstock resources yield potential different using comprehensive evaluation system integrating statistical methods, crop growth process models, geographic information (GIS) techniques. The considered feedstocks included corn, sweet sorghum, cassava, switchgrass, straw, forest residues. spatial–temporal characteristics regional distribution were discussed. results indicate that total straws, residues about 257.17, 2083.55, 44.36, 357.56, 1031.62, 924 million tons at time points, respectively. In first stage, year 2020, totaled 21.55 tons. An advantage was demonstrated by Northeast China. A positive also identified East China, such as Tianjin. second from 2020 2030, is estimated be 145.42 increase South areas Yunnan, Guangxi, Guizhou. third based switchgrass 92.99 straws 14.76 if 5% these are fully used for producing Regions large further expanded. Interregional flows international cooperation help meet whole nation’s requirement.
