Director Robert Miller of the Whittle Laboratory discusses the necessity of disruptive technologies such as cryogenic hydrogen fuel and hybrid electric flight to achieve net-zero aviation by 2050. Miller emphasizes the importance of Operation Blue Skies to mitigate contrail-induced cloud formation, enhance system efficiency, scale up sustainable aviation fuels, and invest in experimental technologies like hydrogen-powered aircraft. The aviation industry is urged to focus on distinct leverage points over the next five years to achieve decarbonization by 2050. Sustainable aviation fuels are already in use, with the European Union mandating 6% sustainable flight by 2030, but efficient resource management is crucial to prevent resource depletion in other sectors. 'Moonshots' involving high-reward experimental programs are proposed, exploring the viability of technologies like hydrogen as a lighter fuel alternative and clean hybrid electric aircraft for shorter flights. Demand management strategies are highlighted, suggesting a need for technology development to achieve net-zero aviation amidst rising global emissions from increased air travel.
