纤维素乙醇生产尚未成规模。纤维素乙醇工业尽管略有停滞,商业项目还是有较大进展。2014年商用纤维素乙醇取得突破,美国因此建立了乙醇基可再生能源标识数(RIN),并有POET先导项目厂试生产,并已有一些较小装置开始生产RIN纤维素乙醇。在巴西,已有两套出口型纤维素乙醇装置投产,按RFS标准出口美国。虽然这些项目算得上纤维素乙醇发展的重要里程碑,但要做到数量可观、运行可靠、经济可行,还得进一步的检验。2014年美国项目受挫,以木材废料和非粮食作物
Cellulose ethanol production has not yet reached a scale. Despite a slight stagnation in the cellulosic ethanol industry, there has been some progress in commercial projects. As a result of a breakthrough in commercial cellulosic ethanol in 2014, the United States has therefore established an ethanol-based Renewable Energy Label (RIN) and piloted production at the POET Pilot Plant, and some smaller units have started production of RIN cellulose ethanol. In Brazil, two sets of export cellulosic ethanol plants have been put into production and exported to the United States according to RFS standards. Although these projects count as an important milestone in the development of cellulosic ethanol, they must be tested in large quantities, reliable and economically viable. US projects suffered a setback in 2014 with wood waste and non-food crops
