Airbus has lifted the curtain just a tad and given us a glimpse at the future of commercial aviation. At the Airbus Summit 2025 in Toulouse, the company presented a view of the technology that will create the single-aisle airliner of tomorrow.
Airbus explained that it ran the numbers and found that, while it could build a successful hydrogen airliner, the plane would be successful in the same way that Concorde was successful. In other words, a technological triumph, but a commercial failure.
I take from that, that we will only get technological breakthroughs away from oil after we break everything down and rebuild from scratch. Because the economy that allowed setting up fuel infrastructure a century ago, is now a much tighter fit.
Yes, but hydrogen has significantly more flaws than most other options. It’s been around for 50 years, has never been a commercial success, and just inherently kinda sucks.
Electricity has been around that long too though, yet there are no serious electric passenger planes (with a decent range)
It has it’s flaws, but it may have a higher ceiling in terms of usefulness. They say they can make it work, which is more than I hear about electric planes for example.
We should be financially encouraging 0 carbon planes, without controlling how, then let the engineers work what tech to do it with.
Worldwide diesel/kerosene biofuel production is too low. Last time airbus made a demo on 100% biofuel made from algae, they bought the output of a whole year to run a single long haul flight.
There is a reason they say Sustainable Aviation Fuel (SAF) and not biofuel. They also need e-fuel / synthetic fuel made from hydrogen in addition to biofuel.
Just like any other hydrogen powered… Anything.

It’s more that Hydrogen is an inherently shit way of powering a vehicle, and liquid fuels are much easier to store and transport.
Biofuels are a much better option, in my view.
…then there should be regulatory actions to help make them viable
Subsidising an inherently flawed technology isn’t the way to go.
What are the other 0 carbon flight options? They are all flawed.
We can engineer our way through flaws with enough effort though.

You can also run an aircraft on biofuel with little to no modifications, with none of the downsides of hydrogen.

There is a lot of biofuel being made of other fuel types though, so no reason why production of aviation biofuel can’t ramp up.
