Pratt & Whitney Canada is leading a four-year, university-industry biofuel research project under a Canada-India science and technology agreement. P&WC and its partners will test and compare second-generation biofuels that do not compete with food resources, such as jatropha, algae and biobutanol.
Continental Airlines last month said it would end all pilot furloughs this year to stem excessive pilot-training costs at its Continental Express subsidiary. A “flow-through” agreement negotiated in ConEx’s pilot contract in 1998 allows furloughed mainline pilots to bid for positions at the regional airline.
Honeywell Aerospace, along with Honeywell subsidiary UOP, Airbus, JetBlue and International Aero Engines (IAE), are joining efforts to develop a sustainable biofuel, using feedstocks that do not compete with food or water resources. The five partners will focus on converting bio feedstocks to commercial aviation fuels. Those feedstocks could be algae.
Airbus and Shell recently made the first ever commercial flight using liquid fuel processed from gas when an A380 airliner flew from Filton in the UK to the airframer’s Toulouse, France headquarters. The flight marked the start of a program to evaluate the environmental impact of alternative fuels in the airline market.
Synthetic fuel seems to be the new Holy Grail of air transport. The prospect of oil reserve depletion, the need to curb CO2 emissions and energy security concerns are all encouraging the industry to find a viable alternative to the current jet-A1 kerosene that can be used in current engines.
General Electric’s research arm and the U.S. Defense Advanced Research Project Agency (Darpa) have joined forces to develop an entirely bio-based jet fuel to reduce U.S. dependence on foreign oil. The main challenge is to make the conversion process efficient. The project envisions a conversion efficiency, by energy content, of crop oil to JP-8 surrogate of between 60 and 85 percent.
Green Flight International last month conducted the first flight of a jet using 100-percent biodiesel fuel. The experimental test flight was flown by an L-29, a military aircraft that is rated to fly on a variety of fuels, including heating oil, making it a “preferred platform” for testing biodiesel in jet engines.
In a nod to increasing concerns about the environmental impact of aircraft, CFM International has successfully tested one of its engines fueled by a mix of biofuel and normal Jet-A1 kerosene.The company said the target is for a 20-percent reduction in carbon dioxide emissions.
As oil prices remain above the $60 per barrel mark, operators, oil companies and government regulators are showing ever more interest in alternative jet fuels. At a March 8 speech at the U.S.
Airliners now entering revenue service will be around for the next few decades, over which time forecasters expect the cost of kerosene to rise significantly. Higher oil extraction costs and likely carbon dioxide (CO2) emission limits will no doubt radically alter air transport economics. The industry will simultaneously have to drastically reduce CO2 emissions from aircraft engines and find alternative fuels for them.
