Advanced biofuels, also referred to as drop-in replacement are renewable fuels, other than ethanol derived from corn starch, that has greenhouse gas emissions that are at least 50% less than baseline (average) lifecycle greenhouse gas emissions. These include renewable diesel, renewable jetfuel, and renewable gasoline. Advanced biofuels can be blended with their petroleum counterparts and can be used and transported in existing infrastructure. Advanced biofuels are not yet commercially produced and in the pilot project stage. The US and Navy signed an MOU (GIFTPAC) to encourage the development of advanced biofuels and selected Hawaii as the first region for the development of the industry.
