Embraer and GE recently held a series of test flights in an E170. The tests, flown out of Embraer’s Gavião Peixoto facilities, benchmarked the operational characteristics of the airplane and its GE CF34-8E engines when powered by HEFA (hydro-processed esters and fatty acids) fuel under a broad range of unique flight conditions.
San Diego-based SG Biofuels (SGB) announced today it has teamed with JetBio–an initiative that includes Airbus, the Inter-American Development Bank, Bioventures Brasil, Rio Pardo Bioenergia, Air BP and TAM Airlines–to accelerate the production of crude jatropha oil as a source for biojet fuel in Brazil.
A revised specification issued by standards organization ASTM International establishes requirements for the use of biofuel blends in conventional jet fuel, facilitating wider use of cleaner-burning “renewable” fuels made from plants.
A coalition of FBOs and fuel distributors who sell leaded avgas in California has filed a lawsuit against the Center for Environmental Health (CEH) and the state’s Attorney General in response to a planned lawsuit announced in May over the sale and use of leaded aviation gasoline.
I recall being at first surprised, then relieved, by the oft-quoted statistic that aviation accounts for just 2 percent of global CO2 emissions. It seems like such a small amount in the grand scheme of greenhouse gases. But a recent report by the World Economic Forum cautions against complacency on the emissions front.
At this year’s Paris Air Show, some big players bellied up to the biojet bar. Boeing flew one of its new 747-8s from the U.S. to the show fueled by a mix of 85-percent jet-A and 15-percent camelina plant oil derivative; Honeywell–the jet-engine and avionics manufacturer–made the trip using a 50-50 mix in a Gulfstream G450.
Honeywell’s corporate Gulfstream G450 made bizav history when it landed at Le Bourget in time for the Paris Air Show after the first transatlantic flight using biofuel, a trip that resulted in net equivalent savings for the seven-hour flight of roughly 5.5 metric tons of CO2.
At last week’s Paris Air Show strong examples of leadership in efforts to reduce air transport’s environmental footprint came from two sources that, at least in the eyes of sometimes sanctimonious European observers, have not been seen as being at the vanguard of such moves: the U.S. and business aviation. During the administration of former President George W. Bush, the U.S.
Here we are, 41,000 feet in the air, sailing along at a little more than 476 knots and a little more than halfway from Morristown, N.J., to the Paris Air Show. We’ve got a biofuel blend of Honeywell’s finest and jet-A feeding engine one and straight jet-A in the other. The G450’s Rolls-Royce engines appear to be perfectly happy on a diet of either, and the flight is as smooth as a glass-top table.
Two years ago at the last Paris Air Show, jet biofuels were just talked about, but at the airshow this week they appear to have come of age. On Saturday, Honeywell made history by landing a Gulfstream G450 at Paris Le Bourget after the first transatlantic flight using a blend of biofuel and jet-A.
