Airbus, Honeywell team on biofuel for airplanes

Along with JetBlue Airways Corp. and International Aero Engines, they plan to produce fuel from vegetation and algae-based oils that do not compete with existing food production or land and water resources. Currently, commercial airlines run their planes on kerosene, though some alternative fuels are being tested.

The companies did not say how much they would invest in the project, nor did they give any targets for biofuel production prior to 2030. International Aero Engines is a multinational consortium whose shareholders include United Technologies Corp.'s Pratt & Whitney and Rolls-Royce.

President Bush in December signed an energy bill that requires refineries to use 36 billion gallons of ethanol a year by 2022 with at least 21 billion gallons of the alternative fuel coming from nonfood raw materials.

The U.S. currently produces nearly 7 billion gallons of ethanol annually, all from corn. Critics say reliance on that crop has helped inflate food prices, while skeptics note there is no way to know when biofuels from other sources will be commercially available.

Airbus and its partners are undeterred.

"In order to replace a significant portion of that jet fuel with bio-jet, we need to find something that has much greater yield than the current biomass sources available," Sebastien Remy, head of alternative fuels research programs for Airbus, said in a release. "Airbus believes that second-generation bio-jet could provide up to 30 percent of all commercial aviation jet fuel by 2030."

A spokesman for Airbus, which is owned by European Aeronautic Defence & Space Co. NV, on Thursday said it's expected the new biofuel will be a "drop-in" replacement for today's kerosene jet fuel and that engine modifications should not be required. Airbus and Chicago-based rival Boeing Co. dominate the global market for commercial airplanes carrying 100 or more people.

On Wednesday, DuPont executives said a new joint venture with a Danish company will enable production of cellulosic ethanol that costs less to manufacture than corn-based ethanol and won't drive up food prices. The companies plan to invest $140 million in the U.S.-based venture and hope to have a commercial-scale demonstration facility, making fuel from the leaves and stalks of corn and from the remnants of sugarcane stalks, operating by 2012.

Speaking a Wednesday hearing on the global rise in food prices, Sen. Joseph Biden, D-Del., applauded DuPont's plan.

"We must push harder in the search for alternatives, and not just because of the price of food," Biden said. "Our foreign policy is held hostage to our dependence on imported oil."
