Fly Net Zero by 2050......................Sustainable aviation fuel (SAF)

To reach Net Zero by 2050, the aviation sector will require around 450 billion litres of sustainable aviation fuel (SAF). Across the industry, we see evidence that work is ongoing to develop the existing knowledge, availability and technology to deliver on SAF. There are a lot of developments in this area: 

  • In collaboration with Braathens Regional Airlines and Neste, ATR performed a series of flight tests with 100% Sustainable Aviation Fuel (SAF) in one engine, an interesting development as the current legal limit is 50% blend. Meanwhile, Turkish Airlines flew for the first time on SAF using its Airbus A321 between Istanbul and Paris CDG. 
  • In the US, Boeing announced the largest procurement of SAF by an aerospace manufacturer, buying 2 million gallons of 30% SAF blend from EPIC Fuels. In Asia, Neste will start a Singapore sustainable aviation fuel plant by Q1 2023 and Airbus, Rolls-Royce, Safran and Singapore Airlines have signed the Global Sustainable Aviation Fuel Declaration at the Singapore Air Show. In Japan, the government aims to have airlines replace 10% of their jet fuel with eco-friendlier alternatives by 2030.

“Sustainable fuel is not a research project that we are doing on the side. It is happening” said Gurhan Andac, GE Aviation engineer working on sustainable fuels in an interview available here

New technology

Airbus and CFM signed an agreement to collaborate on a hydrogen demonstrator to fly by the middle of the decade. Airbus have stated their aim to have a commercial hydrogen plane available by 2035, so this collaboration marks a crucial step towards zero-emissions flight.  

Operations and Infrastructure

Dublin Airport Authority lodges plans for solar farm to help power Dublin Airport and identified a 27-acre site close to airfield to help it target Net Zero emissions. And ACI Europe published its Airport Carbon Accreditation annual report, covering the period 2019-2021. 


HSBC have announced investing $100 million in Breakthrough Energy Catalyst, a program within the larger Breakthrough Energy network founded by Bill Gates, to support the growth of climate critical technologies – direct air capture, clean hydrogen, long-duration energy storage, and sustainable aviation fuels.
