Groundbreaking developments in Sustainable Aviation Fuel production
We are making significant advancements in developing Sustainable Aviation Fuel (SAF) technologies, supported by the DfT-funded UK SAF Clearing House.
A UK SAF mandate was signed into law in November 2024 and has become effective from New Year’s Day 2025. It sets annual targets for fuel suppliers to blend a proportion of SAF into their fuel supply, which increases linearly from 2% in 2025 to 10% in 2030 and then 22% in 2040. The mandate promotes the development of advanced fuels that achieve higher emission reductions.
We are innovators in synthetic fuel production our in "100% drop-in" renewable fuels are fully compatible with existing engines and transport infrastructure. Our process captures carbon dioxide and converts it into a synthetic gas mixture, which is processed into fuel.
With advice and funding from the UK SAF Clearing House, Zero is working to achieve fast-track approval for its Zero® Jet A-1 synthetic Sustainable Aviation Fuel (eSAF) product through the recognised industry-standard American Society for Testing and Materials (ASTM) qualification. This milestone will enable Zero to engage aviation equipment manufacturers to encourage the uptake of its SAF, which is globally unique as a 100% replica of Jet A-1 fuel.
has said “We are delighted to accept the DfT’s SAF Testing Grant to fast track ASTM approval for our 100% replica Jet A-1 synthetic SAF (eSAF), which constitutes a major endorsement from one of the world leaders in sustainable aviation fuels. This grant will enable us to engage with Original Equipment Manufacturers (OEMs - the companies that design and build aircraft and their components), and share ongoing results, with an accelerated timeline that would make Zero one of the first eSAF producers in the world to achieve ASTM certification and the first to do so through the UK SAF Clearing House. We are grateful to have the support of the UK Government as we ensure that our fuel meets the highest standards for mass adoption.”
The UK SAF Clearing House is crucial in these developments. Funded by the Department for Transport (DfT), it provides grants and support for the development, testing, qualification, and production of SAF to establish the UK as a global leader in SAF production and usage.
