A new flight plan
Sustainable aviation fuels (SAF) acting as drop-in substitutes for the fossil fuel kerosene are expected to play a leading role in decarbonising aviation. They are currently produced with materials like used cooking oil and animal fat waste, but new low-carbon feedstocks are needed to scale up output and ensure future flights are truly sustainable
Production technologies often rely on a source of carbon dioxide as a feedstock to produce sustainable fuels
EASY SOLUTION Lower carbon alternatives to jet fuel can be used with today’s aeroplanes and infrastructure
STICKING POINT A shortage in sustainable feedstocks currently available could slow the pace of growth
KEY QUOTE If we want to make sustainable aviation fuels that are as sustainable as possible, it goes back to designing policies that reward those that deliver the highest emissions reductions ...

What net zero looks like around the world
Cities are key enablers of the energy transition. But each city in every area of the world will have a different set of priorities and ideas of how to achieve net-zero by 2050. FORESIGHT examines a city from each continent—and a research station—to show what this global action looks like from seven different perspectives
Why hydrogen trains are tracking hot
Hydrogen suffers from an abundance of hype, particularly about what it can be used for in the energy transition. Wild claims for the application of hydrogen, with little basis in current science and commercial reality, have worked to obscure the realistic opportunities for putting truly clean hydrogen to work here and now

Hydrogen sector targets production boost
Energy losses in the production process contribute to making hydrogen produced with renewable energy expensive. Companies and researchers are working to improve the efficiency of electrolyser technology and scale it up, bringing down the green hydrogen price tag at the same time
Bioenergy under renewed scrutiny amid energy crisis
Burning wood for energy is a divisive matter. Critics say that it is an unacceptably polluting energy source, while proponents insist it is a vital part of the transition away from fossil fuels. Upcoming policy changes and unpredictable geopolitics make a complex issue thornier still
