Just a week after Boeing flew its new 747-8 Freighter from Everett to Paris on a 15 percent biofuel-kerosene mixture, KLM has bettered that flight by flying between Amsterdam’s Schiphol Airport to Paris’s Charles de Gaulle on a 50-50 biofuel-kerosene blend.
The distance was less for the KLM flight, but the proportion of biofuel to conventional jet fuel was greater in the KLM flight.
The fuel the European airline used was half recycled cooking oil supplied by Dynamic Fuels of the U.S. The fuel mixture was burned in both engines of the KLM Boeing 737-800.
The biofuel used in the 747-8 demonstration flight last week was made from camelina, a flowering crop grown in Montana.
Tests have shown that such biofuels burn as well, if not better than petroleum-based fuels while producing less carbon dioxide emissions in their life cycle.
The Amsterdam-Paris flight was the first of what could be more than 200 flights KLM plans to make using the biofuel mixture.
