Dragon’s Den
In order to make air travel more sustainable, the aviation industry is working on a range of solutions.
Most aviation fuel in use today is created from fossil fuels. Pretend you are an investor, with £20m to invest in an alternative fuel for future sustainable air travel.
You will hear three pitches on Sustainable Aviation Fuel (SAF), Hydrogen and Electric propulsion and will be asked to vote for the one approach that you want to invest in, so listen carefully and get your critical thinking cap on to decide why one solution should win over another.

AB FAB SAF
- Lower carbon emissions
- Range of sources– biofuels or synthetic
- Already being made and used
- ‘Drop in’ fuel – no costly changes needed to the aircraft or airport
- Government support for production and use
- International support – will encourage further investor confidence

Hydrogen Helen
- H2 has potential to reduce aviation CO₂ emissions
- Help to achieve governments net zero targets for domestic aviation.
- Lower NOx levels
- Higher energy density of H2 would mean not all airports would initially need to have H2 infrastructure
- Required to comply with ICAO noise requirements so will not be nosier than current aircraft

Live, Laugh, Lithium
- Lower emissions compared with fluid state fuels
- Reduction in aviation noise contributions
- Minimising habitat disruption
- Charging procedures easier and safer
- Safer storage compared to experimental alternatives.
- Battery power is safer for ground handlers
