Biofuels Could Be Cleared For Aircraft Use

Approval of biofuels for use in aircraft, expected by mid-2011, is a critical step. A standard for jet fuels using synthesized hydrocarbons has already been crafted and the first annex, covering synthetic paraffinic kerosene (SPK) produced via the Fischer-Tropsch (F-T) process, was approved last year. But a second annex covering bio-SPKs—also called hydrotreated renewable jet fuel (HRJ)—is eagerly awaited, as these promise to reduce aviation’s greenhouse-gas emissions (see p. 60).
