RAF Typhoon jet has flown on ‘chip fat’ for the first time in breakthrough for green fuels

AN RAF Typhoon jet has flown on “chip fat” for the first time in a breakthrough for green fuels.

The £125million fighter was refuelled in mid-air with an almost 50:50 blend of reused cooking oil and regular jet fuel.

A C-130 Hercules transport plane also used the sustainable blend, after earlier trials with drones, microlights and a Voyager cargo plane.

The RAF said its biofuel was made from “waste-based sustainable feedstocks, such as used cooking oil”.

It reduces carbon emissions “by up to 80 per cent compared to conventional jet fuel”, the RAF added.

Squadron Leader Gaz Evans said there was no loss of performance.

He said: “We believe we are the first air force to conduct an air-to-air refuel operation with a sustainable aviation fuel blend at this level.”

Defence Minister Baroness Goldie hailed a “key achievement” in the RAF’s mission to be carbon neutral by 2040.

She said it was “crucial for the RAF’s future resilience”.
