Measuring Up To Standards

ASTM International, formerly known as the American Society for Testing and Materials, develops “international consensus standards” for many industries, using input from its members in many fields and disciplines.  Their D-7566-11 “Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons” governs what can be put into jet and turbo-prop aircraft.  Updated in July 2011, it now allows the use of biologically-derived fuel “without the need for special permissions,” according to SAE International, itself a standards organization, and as reported by Patrick Ponticel. United Airlines was quick to take advantage of the revised standard, using “Solazyme-supplied algae oil that was refined into jet fuel by Honeywell’s UOP division near Houston. The blend used for the November 7, Boeing 737-800 flight was 40-percent Solazyme’s Solajet and 60-percent petroleum-derived commercial jet fuel (Jet-A).” SAE explains that, “Under the ASTM standard, up to 50-percent bio-derived synthetic blending components can be added to conventional jet fuel. These renewable fuel components, called hydroprocessed esters and fatty acids …

Dr. Seeley provided several links that reminded this writer of an earlier effort to convert the debris of our affluence into something other than effluent. A Daily Press report from December 21, 2010 by Cory Nealon, showed that at least one lawmaker is aware that there is a “green” aviation industry.  “U.S. Sen. Mark Warner, D-Va., is spearheading a potential multibillion-dollar endeavor to make Hampton Roads a leader in the emerging field of green aviation. “The effort, which would draw on the region’s rich history of aeronautics research, is in its initial stages of development, Warner said Tuesday. “Preliminary plans include tapping NASA Langley Research Center and partner organizations, such as the National Institute of Aerospace and Science and Technology Corp., all of which are based in Hampton.” The local nature of Senator Warner’s efforts is informative, considering the global nature of climate change and shrinking fossil fuel energy supply issues that must be addressed. Kerry Reals, writing in Flight Global, forecasts …
