No Further Developments Until Fuel Is More Redily Available

After a six-month practical trial involving biosynthetic fuel, Lufthansa said this week that it had successfully operated 1,187 biofuel flights between Hamburg and Frankfurt. According to initial calculations, CO2 emissions were reduced by 1,621 tons. Total consumption of the biokerosene mix amounted to 1,715 tons. 

“Our burnFAIR project went off smoothly and to our fullest satisfaction. As expected, biofuel proved its worth in daily flight operations,” confirmed Joachim Buse, Vice President Aviation Biofuel at Lufthansa.

The highlight of the biofuel trial at Lufthansa will be the first scheduled transatlantic flight to the United States, planned for January 12tth.  A Boeing 747-400, carrying about 40 tonnes of a biosynthetic fuel mix, will fly from Frankfurt to Washington. With this flight alone, Lufthansa expects to reduce CO2 emissions by 38 tonnes, equivalent to the CO2 emissions of six scheduled flights between Frankfurt and Berlin.

The aviation industry has undertaken a great deal in terms of climate protection and has set itself ambitious targets. In line with IATA’s industry-wide goal, airlines must reduce their net CO2 emissions by 50 per cent by the year 2050 compared to 2005. “If we want to protect our climate and thus our future in a sustainable manner, we need innovative ideas and technologies and an environmentally friendly alternative to fossil fuels – particularly in view of the growing demand for mobility worldwide,” said Christoph Franz, Chairman of the Executive Board of Deutsche Lufthansa AG.

Biosynthetic kerosene is just as reliable as conventional jet fuel but the environmental effects are more positive. Thanks to the higher energy density of biofuel, it has been possible to reduce the fuel consumption by more than one per cent. Furthermore, biosynthetic kerosene is free of sulphur and aromatic compounds. The principle behind biofuel is simple and is based on the carbon cycle. Plants withdraw CO2 from the atmosphere through photosynthesis. When aircraft engines burn biofuel, this CO2 is released back into the atmosphere. Biofuel emits about 50 per cent less CO2 than conventional fossil fuels.

The the tests will be winding down until biofuels are more redily available. “As a next step, we will focus on the suitability, availability, sustainability and certification of raw materials. But first we must tap into this market. However, Lufthansa will only continue the practical trial if we are able to secure the volume of sustainable, certified raw materials required in order to maintain routine operations,” project manager Joachim Buse stressed.

A Lufthansa Airbus A321 was used to operate scheduled flights on the Hamburg-Frankfurt route between July 15th and December 27th last year. One of the aircraft’s engines was powered by a 50-50 blend of regular fuel and biosynthetic kerosene. The aim of this long-term trial was to gain experience in the use of biofuel and collect long-term data. At the same time, the test flight enables the effects of biofuels on the environment and on the maintenance and life time of the engines to be examined.
