  • A substantial component of aviation’s climate impact is presently caused by non-CO2 effects, most notably contrail formation; if weather conditions are right, these can evolve into so-called contrail cirrus. A recent assessment of the drivers of climate change due to aviation estimated the present-day climate effect of contrail cirrus was 65-70% greater than that of CO2, albeit with a significantly greater uncertainty. Clearly, if that contribution could be mitigated, it […]
  • The UK government has opened a public consultation on an action plan for the UK aviation sector to reach its net zero emissions by 2050 target, which it calls ‘Jet Zero’. Its draft strategy relies on a combination of five different measures: making airspace system efficiencies, building a sustainable aviation fuels (SAF) industry, developing zero emission aircraft technology, using cost-effective market-based measures and working to influence the behaviour of air […]
  • An analysis by major sustainable aviation fuels (SAF) supplier SkyNRG of the European Commission’s ReFuelEU Aviation initiative, part of the ‘Fit for 55’ package of legislative proposals unveiled last week, shows around 300 SAF plants with an average production capacity of around 100,000 tonnes per year will be needed by 2050 to meet EU demand under the SAF blending mandate that underpins the initiative. With only 15 plants expected to […]
  • Pratt & Whitney Canada (P&WC) is restarting activity on its hybrid-electric propulsion technology with the aim of ground testing a de Havilland Dash 8-100 equipped with a demonstration powerplant in 2022, leading to flight testing in 2024. The project is being backed as part of a C$163 million ($129 million) investment supported by the governments of Canada and Quebec, and is a component of the country’s green recovery plan, reports […]
  • Released as part of the European Commission’s ‘Fit for 55’ climate package, the long-anticipated ReFuelEU Aviation proposal confirms imposing a mandate on fuel suppliers to include sustainable aviation fuel (SAF) in aviation fuel supplied at EU airports. The obligation would commence from 2025 at 2% SAF, gradually increasing to 63% in 2050. The proposal also includes a sub-obligation of 0.7% for e-kerosene from 2030. To avoid fuel tankering, an obligation […]
  • The EU’s ‘Fit for 55’ legislative package of proposals unveiled by European Commission President Ursula von der Leyen is likely to have long-term consequences for the aviation sector. Parts of the package have already been widely flagged, such as the introduction of an incremental blending mandate for sustainable aviation fuels and tightening of EU Emissions Trading System (EU ETS) provisions for intra-European flights. However, a proposal to remove the tax […]
  • Sustainable aviation fuel (SAF) production on the US West Coast has been boosted with the announcement that Boeing will invest in SkyNRG Americas’ first dedicated SAF plant in the country, while JetBlue Airways said it will increase its usage of SAF by taking World Energy’s product for its operations at Los Angeles International Airport. SkyNRG, which is based in the Netherlands, is looking to establish a series of SAF production […]
  • With a conditional order for 100 Heart Aerospace ES-19 airliners, United Airlines has placed another big bet on the future size and shape of its aircraft fleet, with an emphasis on electrically powered airliners and investments in what it has described as “emerging technologies that decarbonise air travel”. The US major announced an agreement to acquire 100 ES-19s, a 19-seater being developed by Sweden’s Heart Aerospace, while its regional partner […]
  • Although using CO2 from direct air capture (DAC) is important for e-fuels production in a net zero energy system, it is currently too expensive and could place a very high cost and technology risk burden on the e-fuels sector, concludes an E4Tech study commissioned by Transport & Environment (T&E) and presented in a webinar hosted by the Brussels-based NGO. The study recommends point source CO2 capture – capturing CO2 from […]
  • MRO and technical aircraft services provider Lufthansa Technik has joined with Hamburg Airport in an initiative to design and test maintenance and ground processes for handling liquid hydrogen (LH2) that is expected to be used in powering future aircraft. The two-year research project, which has received funding from the city of Hamburg, will also involve the German Aerospace Center (DLR) and the Center for Applied Aeronautical Research (ZAL). As part […]
