Shell developed and produced the 50-50 blend of synthetic Gas to Liquids (GTL) kerosene and conventional oil-based kerosene fuel. The State of Qatar is set to become the world’s leading producer of GTL kerosene when it is put into commercial production from 2012.
The fuel, as an alternative to conventional oil-based kerosene, will contribute to diversification of aviation fuel supply. It also burns with lower sulphur dioxide and particulate emissions than pure conventional oil-based kerosene, making it attractive for improving local air quality at busy airports.
The blend of conventional kerosene and GTL kerosene will be known as GTL Jet Fuel. The flight was the latest step in over two years of scientific work carried out by a consortium consisting of Airbus, Qatar Airways, Qatar Petroleum, Qatar Science & Technology Park, Rolls-Royce, Shell and WOQOD into the benefits of using GTL Jet Fuel to power commercial aircraft. Much of this work is being undertaken at the Qatar Science & Technology Park in Doha.
“Qatar’s position as the GTL capital of the world has been further enhanced with today’s achievement. GTL technology enables us to produce liquid fuels and other products from natural gas. Commercial aviation is one of the exciting new markets that this opens up, helping us maximise the value from our natural resources,” said Abdulla bin Hamad Al-Attiyah, Qatar deputy prime minister and minister of energy and industry.
A delegation of consortium members and international media was onboard flight QR076 for the milestone trip. Data from the GTL flight will be used by scientists in Qatar to further quantify GTL Jet Fuel use benefits.
Qatar Airways CEO Akbar Al Baker, who was onboard the flight, said: “We expect this alternative fuel to provide benefits, particularly the improvement of air quality. This milestone flight is the first step in making this alternative fuel available to airlines.”
The GTL kerosene will be produced in commercial quantities by the Pearl GTL project, currently under construction by Qatar Petroleum and Shell. The project is expected to produce around one million tonnes per annum of GTL kerosene from 2012, enough to power a typical commercial airliner for half a billion kilometres (equivalent to carrying 250 passengers around the world 4,000 times) when used in a 50 per cent blend to make GTL Jet Fuel.
GTL Jet Fuel, with GTL kerosene up to 50 per cent, was fully approved as safe for use in civil aviation by ASTM International (originally known as the American Society for Testing and Materials) last month.
The approval followed two years of separate research and discussion by the ASTM specification group, a separate consensus body consisting of producers, equipment manufacturers and consumers of aviation fuel.
Mohamed Al-Sobai, Vice Chairman and Managing Director of WOQOD, said: “Through its subsidiary QJet, WOQOD is delighted to support the initiative to utilise GTL aviation fuel for Qatar Airways and will ensure adequate supply in Qatar. WOQOD will be working with Pearl GTL in Ras Laffan and with Qatar Airways to bring this initiative to reality by providing storage and supply logistics to Doha International Airport.”
Dr Eulian Roberts, Managing Director of the Qatar Science & Technology Park, said: “The commitment of Qatar Airways and the consortium partners to ensure that new aviation fuel technology is effectively applied is a great example of the kind of research being pioneered at QSTP through its partners. Research activities on alternative and environmentally-friendly fuels like GTL will establish QSTP as a leading international hub for the application of new platform technologies.”
Malcolm Brinded, Shell’s executive director Upstream International, added: “Today’s flight opens the door to an alternative to oil-based aviation fuel. Shell has been developing the technology to convert natural gas into valuable liquid transportation fuels, lubricants and chemical feedstocks for over 30 years. We are now well on the way to launching GTL on a world scale for the first time thanks to our partnership with Qatar Petroleum.”
