Renewable jet fuels. Hydrogen power. Air taxis. All frontiers in the future of aerial tech.

Sustainable aviation fuel (SAF), made from waste oils and agricultural feedstock, will be the main — or perhaps sole — pathway for large jets to hit their carbon neutrality targets by 2050. SAF’s key advantage is it can be used straight away, with no adaptations needed for planes or associated infrastructure at airports. That said, it’s 2-5x more expensive than regular aviation fuel, so using more of it could mean higher air fares.

Startups are tinkering with other technologies that should be able to take a bite out of the industry’s carbon footprint — if the big technical challenges can be overcome. Batteries are doing a great job of replacing fossil fuels in cars but — with planes, things are much harder.; Simplysimply put, batteries are heavy and planes need to be light. Hydrogen also has promise as a jet fuel, but it needs time to mature — possibly decades.

Down on the ground, airports are getting ready for the future. Paris’ Charles de Gaulle is mapping flight paths for the cargo and passenger drones that are expected to someday whizz around terminals. In the Netherlands, Eindhoven airport is using AI to improve aircraft turnaround times, while Amsterdam’s Schiphol airport is hiring robots to help handle passenger luggage.

Meanwhile, flying taxis are hovering in the near distance but they’ll initially be a luxury or premium service, so we probably won’t get to ride in them for a while. The best plan is to snap up the affordable Ryanair seats now, as it seems likely that we’ll be paying more for our flights in 2050.
