Patrick Gruber (Letters, August 6) has correctly pointed out that renewable or sustainable aviation fuels offer immediate benefits for net carbon emission reductions. However, many current technologies derived from bio-crops inevitably compete with food production. Additionally, Fischer-Tropsch-derived fuel incurs high costs through its two-step production process either from CO2 or via conversion of bio-crops to fuel.
Recent breakthroughs by the team I run at Oxford university now enable synthetic aviation fuel to be produced directly — in a one-step process — using only CO2 extracted from air and hydrogen extracted from water using renewable electricity.
These fuels, now based on non-fossil carbon sources, can be used directly in existing aircraft fleets including their associated infrastructure.
The forthcoming COP26 climate conference will be the ideal opportunity to highlight this new cutting-edge technology which not only helps reduce global warming but also provides a sustainable future for aviation.
