New Zealand and Singapore consider ‘green lanes’ as governments sign sustainable aviation partnership

by Tony Harrington

The governments of Singapore and New Zealand will consider introducing ‘green lanes’ for travellers between the countries to help encourage consumer use of flights powered by sustainable aviation fuels. The idea is contained in a groundbreaking Sustainable Aviation Arrangement between the countries, which was signed during a visit to Singapore by New Zealand’s Prime Minister, Jacinda Ardern. The agreement is the first bilateral cooperation on sustainable aviation for both countries, which, together with their aviation industries, have each been exploring decarbonisation measures including sustainable aviation fuel, hydrogen propulsion for aircraft and enabling infrastructure. In addition to studying green lanes, the…
New sustainable fuel partnerships formed as Japan strives for 10% SAF use by 2030

by Tony Harrington

Two new European-Japanese industrial partnerships have been formed to progress the transition of Japan’s air transport sector to sustainable fuels. Paris-based TotalEnergies has joined with Tokyo-based ENEOS Corporation to conduct a feasibility study into the production of sustainable aviation fuel at the latter’s Negishi Refinery by 2025, while aircraft manufacturer Airbus has signed a memorandum of understanding (MoU) with Japanese industrial group Kawasaki Heavy Industries to collaborate on the production of hydrogen fuel, its delivery to airports and its supply to aircraft. The announcements coincided with the release of a new study by global business consultancy McKinsey which highlighted increased…
Regulate jet fuel’s aromatics content to reduce non-CO2 impacts of aviation, says Dutch report

by Christopher Surgenor

Although research is ongoing, it is widely accepted aviation’s contribution to global warming goes well beyond that caused by carbon dioxide emissions alone. One of the main non-CO2 impacts is the net warming effect from the formation of contrails and contrail cirrus caused when aircraft engines emit particulates (soot) at altitude in ice-supersaturated regions. The main culprit is the aromatic content of jet fuel, and fuels with a higher concentration of aromatics and especially naphthalene, a bicyclic aromatic compound, cause higher particulate emissions because aromatics burn slower than other hydrocarbons. Sustainable aviation fuels, on the hand, have negligible concentrations of…

SATAVIA and ACX partner on first-ever carbon trade to monetise aviation’s non-CO2 impacts

by Christopher Surgenor

Weather prediction and navigational technology developer SATAVIA is partnering with AirCarbon Exchange (ACX) to support trading of carbon credits generated by SATAVIA’s contrail prevention technology. The company’s atmospheric modelling enables aircraft operators to optimise flight plans for avoiding contrails, which contribute substantially to aviation’s non-CO2 climate impact. The subsequent climate benefit, say the partners, can be converted into tradable carbon credits in a new market they estimate could be worth up to $9 billion at current nominal voluntary carbon pricing, which is forecast to rise tenfold by 2030. A first ACX trade to monetise contrail prevention activity coincided with a…
Neste to supply over 50 million gallons of SAF to United Airlines for flights from Schiphol

by Christopher Surgenor

United Airlines has entered into a purchase agreement with Neste that provides the right to buy up to 52.5 million gallons of sustainable aviation fuel over the next three years for United flights departing from Amsterdam’s Schiphol Airport, and potentially other airports as well. The deal makes it Neste’s largest to date with a passenger airline and also the first by a US airline to sign an international SAF purchase agreement. United’s Chief Sustainability Officer, Lauren Riley, said the airline had invested more than any other airline so far in SAF production and that it made sense to expand its…
Meeting 2030 SAF targets in the US and Europe needs rapid action on capacity and feedstocks, says report

by Tony Harrington

A new market report by SkyNRG, the Amsterdam-based global provider of sustainable aviation fuels, predicts that both the US and Europe will fall short of their 2030 SAF targets unless production capacity is increased and fuel feedstock sources are expanded, and estimates the need for more than 450 new facilities to meet the 2050 goals of both markets. The report says current US announcements of SAF production rely predominantly on the availability of fats, oils and greases (FOGs), and corn ethanol, “with an optimistic perspective on the availability of FOGs”. It believes a lack of production incentives will limit use…
T&E launches campaign urging corporates to commit to cutting business travel emissions by half

by Christopher Surgenor

European NGO Transport & Environment (T&E) and a coalition of 13 partners have launched a campaign urging corporates to address their travel emissions and lower the level of trips being made for business. They say the dramatic fall in business travel and the rise in the use of videoconferencing as a result of the Covid pandemic presents a once-in-a-lifetime opportunity to lock in emission reductions from global corporate flying. Reducing business flights can also make a significant contribution at a time when there is pressure to reduce dependency on oil, they add, as highlighted in a recent 10-point plan issued…
First net zero emissions transatlantic flight to take place in 2023, pledges UK government

by Christopher Surgenor

The UK government has revealed it expects the first-ever net zero transatlantic flight to take place as early as next year, with an aircraft to be powered solely by 100% sustainable aviation fuel. The announcement came during a visit to the US by Transport Secretary Grant Shapps, who during a meeting with airline executives invited the international sector to work closely with the government to deliver the demonstrator flight. The government says it is committed to drive forward the SAF industry, which had the potential to deliver significant carbon savings, improve domestic fuel security, support thousands of green jobs and…
ZeroAvia in US venture with Shell and unveils Europe’s first landside-to-airside hydrogen airport pipeline

by Christopher Surgenor

Hydrogen-electric aviation pioneer ZeroAvia has unveiled what it claims to be Europe’s first landside-to-airside hydrogen airport pipeline. The 100m-long hydrogen pipeline runs alongside ZeroAvia’s hangar at Cotswold Airport in the UK and will be utilised together with an electrolyser and mobile refueller to use low-carbon hydrogen for its test flight programme. ZeroAvia’s zero-emission powertrains use hydrogen fuel in a fuel cell to create a chemical reaction that produces electricity, which then powers electric motors that spin the propellers, while producing no emissions other than water. The company says the pipeline will help demonstrate and explore the operational safety case for…
Achieving the EU’s 2030 climate goal for aviation will rely heavily on market-based measures, says Eurocontrol

by Christopher Surgenor

As part of the climate neutral by 2050 binding target of the European Green Deal, the EU has set an interim goal of cutting emissions by at least 55% by 2030, based on 1990 levels, and is working on a set of proposals under the ‘Fit for 55’ package to revise and update EU legislation, and put in place new initiatives to ensure EU polices are line with the climate goals. The package has important implications for aviation, and pan-European air navigation organisation Eurocontrol has released an assessment of what it means in practical terms and the extra costs of…
Airport capacity constraints and demand reduction on flying needed to hit net zero target, says report

by Christopher Surgenor

A report by low carbon energy consultants Element Energy (EE) analysing the UK government’s ‘Jet Zero’ strategy to hit net zero aviation emissions by 2050, with interim reduction targets for the 2030s, concludes the scenarios are over-optimistic. The report, commissioned by UK campaign group the Aviation Environment Federation, concludes acting early by halting airport capacity growth along with implementing other demand reduction measures pose a far less risky approach to reaching the targets. EE estimates the aviation sector will need to cut emissions faster and deeper in the near term than the government is currently projecting. The government’s plans overestimate…
