In recent years, production and consumption of biofuels has become controversial, mainly due to the competitive use of natural resources for food/feed and fuel production. Second generation biofuels (with cellulosic ethanol being on top of developments nowadays) have a great potential to provide an economically feasible solution. However, high processing costs related to breaking down cellulosic plant material and converting it to sugar (and fuel), missing infrastructure and environmental impacts can be detrimental. This paper discusses various biofuels technologies and feedstocks that have a potential to emerge as prospective feedstocks for second generation biofuels production in the future on the US market. It also emphasizes existing challenges that could hinder the development of these technologies and their commercialization in the long-term.
近年来，生物燃料的生产和消费已引发争议，主要原因是自然资源在用于粮食/饲料生产和燃料生产方面存在竞争。第二代生物燃料（如今纤维素乙醇的发展处于领先地位）具有提供经济可行解决方案的巨大潜力。然而，与分解纤维素植物材料并将其转化为糖（和燃料）相关的高加工成本、缺失的基础设施以及环境影响可能会产生不利影响。本文讨论了各种生物燃料技术和原料，这些技术和原料未来有可能在美国市场成为第二代生物燃料生产的潜在原料。它还强调了可能长期阻碍这些技术发展及其商业化的现有挑战。
