ASTM International, formerly known as the American Society for Testing and Materials, develops \u201cinternational consensus standards\u201d for many industries, using input from its members in many fields and disciplines.\u00a0 Their D-7566-11\u00a0\u201cStandard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons\u201d <\/a>governs what can be put into jet and turbo-prop aircraft.\u00a0 Updated in July 2011, it now allows the use of biologically-derived fuel \u201cwithout the need for special permissions,\u201d according to SAE International, itself a standards organization, and as reported by Patrick Ponticel.<\/p>\n

United Airlines was quick to take advantage of the revised standard, using \u201cSolazyme-supplied algae oil <\/a>that was refined into jet fuel by Honeywell\u2019s UOP division <\/a>near Houston. The blend used for the November 7, Boeing 737-800 flight was 40-percent Solazyme\u2019s Solajet and 60-percent petroleum-derived commercial jet fuel (Jet-A).\u201d<\/p>\n

SAE explains that, \u201cUnder 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 (HEFA), are identical to hydrocarbons found in jet fuel, but come from vegetable oil-containing feedstocks such as algae, camelina, and jatropha, or from animal fats called tallow.\u201d<\/p>\n

Besides producing its algae-based product, Solazyme, a San Francisco-based company, has teamed with Dynamic Fuels <\/a>to create plant- and animal-based fuel for the U. S. Navy, an early adapter of the technology.\u00a0 With engine manufacturers such as General Electric and Rolls-Royce approving the use of such fuels after careful review and testing of their merit, the future would seem to be promising for these non-fossil alternatives.<\/p>\n

Mike Epstein of GE Aviation notes that \u201c\u2019for some of those companies, it\u2019s a challenge to make a thousand gallons, which is just a beginning point.\u2019 \u00a0To put things into perspective, he said, the amount of jet fuel consumed annually around the world is about 65 billion gallons.\u201d (And that would only be about 2 percent of the world’s total fuel demand! Editor)<\/em><\/p>\n

The allure of domestically-produced fuel and its performance are not lost on engine manufacturers.\u00a0 Following tests on two Embraer engines, Epstein said, \u201cThe fuel performed as expected and is consistent with Jet-A.\u201d \u00a0A Boeing spokesperson adds that \u201cbiofuels have proven to perform even better than conventional jet fuel.\u201d<\/p>\n

Following United flight 1403\u2019s successful outing, Solazyme signed letters of intent to supply 20 million gallons of renewable aviation fuel per year to United starting in 2014.<\/p>\n

“Today’s historic flight with United marked a significant milestone in the history of aviation, and demonstrated the commercial applicability of our drop-in fuel,” said Jonathan Wolfson, CEO, Solazyme<\/a>.\u00a0 “The U.S. Navy has demonstrated the effectiveness of our fuel in multiple vessels over the past year, and we are honored to be working with industry pioneers such as United and Honeywell’s UOP to see this important next step in the commercialization of our renewable fuels.”<\/p>\n

Following closely on the United first flight, a December 5 press release cited Dynamic Fuels, LLC, a joint venture between Tyson Foods, Inc<\/a>. and Syntroleum Corporation<\/a>, as having been awarded a contract to supply 450,000 gallons of renewable fuels to the Navy.\u00a0 Solazyme will assist Dynamic Fuels in fulfilling the contract.<\/p>\n

\u201cThe contract involves supplying the Navy with 100,000 gallons of jet fuel (Hydro-treated Renewable JP- 5 or HRJ-5) and 350,000 gallons of marine distillate fuel (Hydro-Treated Renewable F-76 or HRD-76). The fuel will be used as part of the Navy\u2019s efforts to develop a ‘Green Strike Group’ composed of vessels and ships powered by biofuel.\u201d<\/p>\n

Dynamic Fuels and Solazyme have already worked with KLM Royal Dutch Airlines, Finnair, Thomson Airways and Alaska Airlines in supplying renewables.<\/p>\n

Dynamic Fuels will produce the naval fuel at its Geismar, Louisiana plant using \u201cU.S.-sourced yellow grease (used cooking oil) as well as Solazyme\u2019s tailored algal oil as feedstocks.\u201d\u00a0 Several plusses ensue.\u00a0 What would be disposable waste becomes a less-polluting energy source, frees the U. S. from part of its billion-dollar-a-day foreign oil obligation, and becomes part of Secretary of the Navy Ray Mabus\u2019s commitment to run the Navy on at least 50-percent bio-fuel by 2020.<\/p>\n

The video provides a look at how Dynamic Fuels refines tallow and other animal fats and wastes into a fuel good enough to run in your Rolls-Royce or GE turbofan engine.\u00a0 As we develop more such alternatives, Secretary Mabus’ vision of freeing the United States from foreign wars in the service of protecting oil supplies may be closer to reality, and our energy independence may be more secure.<\/p>\n
