Gasoline and diesel fuel are substantial cause of carbon emissions. The clean vehicles sector tries to reduce emissions through alternative power systems (electric, hydrogen, fuel cells) that require new or materially modified vehicles. In contrast, the biofuels sector broadly seeks to replace gasoline with an alternative liquid, while making no or minimal changes to the vehicle. Biofuels were hit hard in 2008 due to the well-publicized and emotionally-charged 'food vs fuel' debate. In brief, whether growing crops to make biofuels has a significant impact on the quantity or price of food crops. This revived interest in inedible feedstocks and non-food alternatives, such as jatropha and algae. Sufficient supply of good-quality feedstock is a major issue for fuel refiners and vehicle manufacturers. Biofuels can be manufactured from many different feedstock, however the choice of feedstock has a substantial impact on the cost and quality of the resulting biofuel. The quality and characteristics of each biofuel can have an impact on vehicle performance. There are two broad categories of biofuel products: |
Did you know?■ crop prices are a major driver of biofuel price competitiveness ■ 50%+ of ethanol is made from sugar ■ biotechnology is accelerating development of biofuel products | |
