"First transatlantic flight using 100% green fuels to take off"

" First transatlantic flight using 100% green fuels to take off \r\nThe first transatlantic\u00a0flight\u00a0powered only by\u00a0alternative fuels\u00a0is due to take off on Tuesday morning.\r\n\r\nOperated by Virgin Atlantic, it will fly from London\u2019s Heathrow to\u00a0New York\u2019s JFK airport\u00a0at 11:30 GMT.\r\n\r\nAirlines see the flight, which is supported by government funding, as demonstrating that a greener way of flying is possible.\r\n\r\nBut a lack of supply remains a challenge, while other technology will be needed to hit emissions targets.\r\n\r\nSo-called sustainable aviation fuels (SAF) can be made from a variety of sources, including crops, household waste and cooking oils.\r\n\r\nFor this flight, a Boeing 787 will be filled with 50 tonnes of SAF. Two types are being used, with 88% derived from waste fats and the rest from the wastes of corn production in the US.\r\n\r\nFollowing test and analysis, the flight was approved by UK regulator the Civil Aviation Authority earlier this month. A number of companies have been involved in the project including engine-maker Rolls-Royce and energy giant BP.\r\n\r\nThe aviation industry is particularly difficult to decarbonise, but airline bosses view SAF as the most effective tool available to help bring its net emissions down to zero.\r\n\r\nPlanes still emit carbon when using SAF, but the industry says the \u201clifecycle emissions\u201d of these fuels can be up to 70% lower.\r\n\r\nSAF is already used in small amounts, blended with traditional jet fuel, but accounts for less than 0.1% of the aviation fuel consumed around the world.\r\n\r\nIt currently costs more than kerosene, and relatively small amounts are made. Aircraft are usually only allowed to use up to 50% in a blend.\r\n\r\nThere are no dedicated commercial SAF plants in the UK, although the government aim is to have five under construction by 2025, supported by grant funding.\r\n\r\nAirlines see the first long-haul flight using 100% SAF as a significant milestone. But experts say such fuels are not a magic bullet.\r\n\r\nDr Guy Gratton, associate professor of aviation and the environment at Cranfield University, said: \u201cWe can\u2019t produce a majority of our fuel requirements this way because we just don\u2019t have the feedstocks. And even if you do, these fuels are not true \u2018net zeros\u2019.\u201d\r\n\r\nHe said the growing use of SAF had to be treated as \u201ca stepping stone towards future, genuinely net zero technologies\u201d.\r\n\r\n\u201cThis might be e-fuels [which are manufactured using captured carbon dioxide or carbon monoxide, together with hydrogen], it might be hydrogen, it might be some technologies that we still really only have at the laboratory stage.\u201d\r\n\r\nThe UK government also plans to require 10% of aviation fuel to be SAF by 2030.\r\n\r\nAirlines UK, which represents UK-registered carriers, said they must be able to access enough affordable SAF to meet such a requirement, with as much as possible coming from the UK.\r\n\r\nIts boss Tim Alderslade said: \u201cThe last thing we want is higher fuel costs for UK passengers compared to the rest of Europe and the US, with worse sustainability outcomes and thousands of new jobs lost overseas.\u201d\r\n\r\nEnvironmental campaigners say the only way to cut emissions quickly is to fly less.\r\n\r\nBut UK ministers and the industry have insisted they believe \u201cnet zero\u201d by 2050 is achievable with passenger numbers increasing.\r\n\r\n "
