Aviation
Air travel has become an integral part of our lives. With global aviation emissions accounting for 2-3 percent of all CO2 emissions and now with firm mandates and regulations in place to decarbonise the sector, there is a pressing need to find alternatives to conventional jet fuel. Explore how new sustainable fuels are addressing the need to decarbonise this hard-to-abate sector.

Our Focus Areas
SAF
PROS:
- No modifications required to existing fueling infrastructure
- Significant carbon reductions compared to traditional jet fuel
CONS:
- High production costs
- Heavy reliance on bio-feedstock
eSAF
PROS:
- Potential to be a carbon neutral fuel if produced using renewable energy
- Higher feedstock availability
- No modifications required to existing fueling infrastructure
CONS:
- Significant reduction in cost of production required for commercial viability
Batteries
PROS:
- Zero carbon emissions
- Strong power dissipation performance
CONS:
- Low energy density – battery technology limited to short-haul flights
- Battery materials may have high carbon impacts
Hydrogen
PROS:
- High energy density by weight
- Zero carbon emissions
CONS:
- Requires change to existing fueling infrastructure
- Low volumetric density – creating storage challenges
- High production costs
Market Share Size
The aviation industry has pledged to decarbonise by implementing more sustainable alternative fuel options. Currently Jet-A1, the aviation fuel derived from crude oil, dominates the market.
Going forwards, SAF derived from biomass is expected to increase its market share given it is the most readily available drop-in fuel.
By 2050 more advanced fuels should appear and in a net-zero scenario eSAF and SAF will need to have a majority share with batteries and potentially hydrogen having a minor share for short haul journeys.
However, achieving net zero for the industry presents a complex set of challenges, including technology commercialisation, fuel efficiency & performance, infrastructure requirements and importantly cost of production.
Our expertise in Aviation:
Our experience is around supporting investment into sustainable aviation fuel projects. We’ve provided market, technical and environmental support (from due diligence to independent reviews) for some of the largest aviation fuel projects. Our experience is wide-ranging from understanding how the market for bio-feedstocks might evolve through to deep technical understanding of sustainable aviation fuel pathways.
