Industrial fermentation of renewable diesel fuels

摘要

In commodity chemicals, cost drives everything. A working class family of four drives up to the gas pumps and faces a choice of a renewable diesel or petroleum diesel. Renewable diesel costs $0.50 more per gallon. Which fuel do they pick? Petroleum diesel will be the winner every time, unless the renewable fuel can achieve cost and performance parity with petrol. Nascent producers of advanced biofuels, including Amyris, LS9, Neste and Solazyme, aim to deliver renewable diesel fuels that not only meet the cost challenge, but also exceed the storage, transport, engine performance and emissions properties of petroleum diesel.
