Hainan Airlines Boeing 787-8 has completed China’s first intercontinental passenger flight with sustainable fuel produced from waste cooking oil from restaurants in China by Sinopec.

According to Xinhua News Agency, Hainan Airlines flight 497 flew from Beijing to Chicago O’Hare International Airport Nov. 21 after flying more than 11,000 km (6,835 miles).

[NEWS] Colorado Company Produces Tree-Based Aviation Biofuel

– October 12, 2016, Renewable Energy From Waste

alaska-air-web_rewGevo, Inc., Englewood, Colorado, has completed production of cellulosic renewable jet fuel that is specified for commercial flights. Gevo successfully adapted its patented technologies to convert cellulosic sugars derived from wood waste into renewable isobutanol, which was then further converted into Gevo’s alcohol-to-jet fuel (ATJ) fuel. This ATJ meets the ASTM D7566 specification allowing it to be used for commercial flights. The revisions to the ASTM D7566 specification, which occurred earlier this year, includes ATJ derived from renewable isobutanol, regardless of the carbohydrate feedstock (i.e. cellulosics, corn, sugar cane, molasses and so on).

[NEWS] Sky’s the Limit on Navy’s Biofuel Focus

U.S. Navy Secretary Ray Mabus has made alternative energy a top priority since taking office in 2009, but this week he took his commitment to new heights, literally.

The civilian leader for the Navy climbed aboard an EA-18G Growler fighter jet as a passenger on one of a series of test flights using 100% biofuel.

Biofuels are not new for the U.S. Navy and Air Force, which have been experimenting with blends on aircraft and ships for several years. In fact, all Navy ships and aircraft are now certified to run on up to 50-50 blends of conventional and alternative fuels.

[NEWS] Biofuel Takes Off With Airplane Travel

Biofuel is now helping power United Airlines flights out of Los Angeles.

United began mixing biofuel with traditional jet fuel earlier this year. The biofuel is made from waste products like animal fats and manure. This farm waste would otherwise rot and produce methane, a potent global-warming gas.

Angela Foster-Rice is the managing director of environmental affairs and sustainability for United. She says the biofuel emits 60 percent less carbon dioxide than regular fuel over its lifecycle.

[NEWS] Biofuels on Jet Flights from Los Angeles to Amsterdam

KLM Royal Dutch Airlines has signed a three-year contract with Los Angeles-based refinery AltAir Fuels and SkyNRG for the supply of sustainable biofuel on all flights between Los Angeles International Airport and Amsterdam Airport Schiphol.

The biofuel will be produced by AltAir Fuels and supplied by SkyNRG.

“Sustainable biofuel is currently one of the most effective ways to reduce CO2 emissions in the airline industry,” KLM president and CEO said. “Owing partly to the companies taking part in the KLM Corporate Biofuel Program, we have been able to take this step, giving a further impulse to the consistent production of biofuel.”

[OPINION] The High-Flown Fantasy of Aviation Biofuels

[Read the opposing view, “Takeoff for Aviation Biofuels: How, Where, When?” by Jim Lane, editor and publisher of Biofuels Digest.]

– by Almuth Ernsting, Co-Director, Biofuelwatch

On 24th February 2008, pictures of Richard Branson tossing a coconut into the air next to an aircraft at Heathrow were broadcast around the world, as he announced the world’s first biofuel flight. Biofuel, he claimed, would “enable those of us who are serious about reducing our carbon emissions to go on developing the fuels of the future.”

Environmental NGOs denounced his test flight as a publicity stunt, intended to deflect attention from the fact that aviation is one of the fastest growing sources of greenhouse gas emissions worldwide, and most carbon intensive form of transport. As far as Branson and his airline, Virgin Atlantic, were concerned, the flight was indeed no more than a stunt: The “biofuel test flight” burned 95% ordinary kerosene and just 5% biofuels, made from coconut and Brazilian babassu nut oil. Virgin Atlantic has not used any biofuels since that day.

Since then, however, at least 24 other airlines have blended biofuels with kerosene. By September 2015, more than 2,050 such flights had taken off, most by commercial airlines, some by the US and Dutch military and US and Canadian research institutes. This year, KLM has launched a series of 80 passenger flights with biofuel blends, and since March, United Airlines has been using such blends for regular flights between Los Angeles and San Francisco. They aim to expand their use to all their flights out of Los Angeles. Across the aviation industry, biofuel use and investments have moved far beyond what could be considered a mere publicity stunt.

Even if biofuels were carbon neutral – which is far from the case – there is no realistic prospect of them making any significant dent in aviation’s contribution to global warming. Between 2002 and 2012, global jet fuel use increased by one-fifth, to 5.42 million barrels a year (around 695,000 tonnes). Apart from a minor dip during the global financial crisis in 2008-2009, it has been growing year after year. Global biofuel production has reached the equivalent of around 70.8 million tonnes of oil a year, accounting for little more than 2% of the world’s transport fuels. However, as we shall see below,only a small fraction of the biofuels which are being produced annually today could conceivably be upgraded for use in aviation. Nearly the world’s entire biofuel infrastructure is for ethanol and biodiesel, which cannot be used in aircraft.
