New Delhi: With global aviation bodies like International Air Transport Association pressing for reduction of carbon emissions in the sector, some major airlines have carried out test flights using biofuel and alternative fuel, which are cleaner.

Though the civil aviation sector accounts for only two per cent of the global carbon emission, the industry has conducted sufficient research on the usage of alternative fuels, from the prospective of both environment and cost.

Qatar Airways, Virgin Atlantic, Continental Airlines, Air New Zealand and Japan Airlines are some of the global carriers which have carried out experiments to fly their aircraft using a blend of alternative fuel and aviation turbine fuel.

Qatar Airways CEO Albar Al Baker recently said that his country was set to become the primary supplier of a new and cleaner jet fuel that powers an aircraft by a refined form of natural gas.

The airline, he said, was also planning to use the Gas-to-Liquid (GTL) fuel in many of its planes over the next few years. GTL, a 50-50 blend of gas and conventional oil-based kerosene fuel, was successfully tested last month on a Airbus A 340-600 aircraft, which flew from London Gatwick to Doha using Rolls Royce Trent engines.

"Qatar's position as the GTL capital of the world has been enhanced with this achievement. GTL technology enables us to produce liquid fuels and other products from natural gas in our bid to achieve carbon-neutral growth," he said.

The first experiment with green fuel was conducted by Virgin Atlantic when it flew a Boeing 747 jumbo from Heathrow to Amsterdam in February 2008 with one of its engines powered by a fuel made out of coconut and babassu nut that is found in the Amazon forests.

Continental Airlines, Air New Zealand and Japan Airlines have also carried out similar biofuel experiments with flying Boeing 737s and Boeing 747s in January this year.

Pointing out that emission reductions could be achieved through technology, infrastructure and sustainable biofuels, the IATA has said the prospects of biofuels were the most exciting because for the first time air transport has the possibility of an alternative to traditional jet fuel.
