Ethanol produced from cellulosic biomass is examined as a large-scale transportation fuel. Desirable features include ethanol's fuel properties as well as benefits with respect to urban air quality, global climate change, balance of trade, and energy security. Energy balance, feedstock supply, and environmental impact considerations are not seen as significant barriers to the widespread use of fuel ethanol derived from cellulosic biomass. Conversion economics is the key obstacle to be overcome. In light of past progress and future prospects for research-driven improvements, a cost-competitive process appears possible in a decade.
从纤维素生物质中生产的乙醇被视为一种大规模的运输燃料。理想的特点包括乙醇的燃料特性以及在城市空气质量、全球气候变化、贸易平衡和能源安全方面的益处。能源平衡、原料供应和环境影响方面的考虑因素并不被视为广泛使用纤维素生物质衍生燃料乙醇的重大障碍。转化经济是需要克服的关键障碍。鉴于过去的进展和未来研究驱动改进的前景，一种具有成本竞争力的工艺在十年内似乎是可行的。
