Oils, food waste and algae to power RAF jets under new Ministry of Defence plans


Algae, alcohol and household waste will power RAF fighter jets under new Ministry of Defence (MOD) plans to slash carbon emissions.

Aircraft including F-35s, Typhoons and Wildcat helicopters currently use conventional fuel, but could use up to 50 per cent sustainable sources in the future, after MOD’s changed aviation fuel standards came into effect in November 2020.

Known as ‘drop-ins,’ sustainable fuel sources include hydrogenated fats and oils, wood waste, alcohols, sugars, household waste, biomass and algae.

Defence Secretary Ben Wallace commented on the announcement: “The UK is leading the way in sustainability and by refining our aviation fuel standards we are taking simple yet effective steps to reduce the environmental footprint of defence.

“As we strive to meet this Government’s Net Zero carbon emissions target by 2050, it is right that we step up to spearhead these positive changes across both military and civilian sectors.”

It is estimated that by substituting 30 per cent of conventional fuel with an alternative source in a jet travelling 1,000 nautical miles could reduce CO2 emissions by 18 per cent.

The MOD’s move to allow up to 50 per cent sustainable fuel marks a huge shift in global fuel consumption and opens the door for thousands of civilian and military aircraft to be fuelled with Sustainable Aviation Fuels (SAFs).

Not only do Australia and several NATO countries rely on the UK’s standards to influence what fuel they use, but civil and commercial airlines in the UK follow the defence standard as there is no commercial equivalent.

UK suppliers are also more likely to offer the same standard for commercial aircraft if they are already developing and importing sustainable fuel to supply defence.

Transport Secretary, Grant Shapps, commented: “Making all forms of transport more sustainable is critical if we are to meet our ambitious Net Zero target.

“From powering RAF Jets to the passenger planes which get us from A to B, sustainable fuels will play a huge part in decarbonising aviation and I’m excited to explore the possibilities as we make transport cleaner, greener and more efficient.”

Adopting greener technology in the MOD’s aircraft fleet is part of the department’s strategy to reduce its contributions to carbon and greenhouse gas emissions.

Measures like this will be reflected in the department’s ongoing Climate Change and Sustainability Review, led by Lt Gen Richard Nugee.

The review will focus on a range of initiatives from the MOD’s NZ50 strategy to setting the right baseline for defence’s emissions and carbon footprint, with findings set to be published in early 2021.

Lieutenant General Richard Wardlaw OBE, Chief Defence Logistics and Support, commented: “The Defence Strategic Fuels Authority has been working tirelessly with industry partners to change the Defence Standard for Aviation Fuel, allowing SAF deliveries to the MOD.

“This is a significant change for Defence, enabling us to take a key step towards reducing our CO2 footprint, consistent with our wider ambition for achieving NZ50. And this is only the beginning.

“With the Defence Climate Change and Sustainability Strategy, due for release later this year, we are at the start of a journey to adopt a range of greener policies and new greener technologies, so that we can reduce our environmental impact while enhancing our operational capabilities.”
