Jet fuel from thin air: Aviation’s hope or hype?

“This is the future of aviation,” Oskar Meijerink tells me in a café in Rotterdam airport.

His firm, in partnership with the airport’s homeowners, is planning the world’s first industrial manufacturing of jet fuel made, partly, from carbon dioxide (CO2).

Based on the airport, it would work by capturing CO2, the gasoline which contributes to world warming, from the air.

In a separate course of, electrolysis splits water into hydrogen and oxygen. The hydrogen is combined with the captured CO2 to type syngas, which might be reworked into jet fuel.

The pilot plant, which goals to provide 1,000 litres of jet fuel a day, will get is vitality from photo voltaic panels.

The companions within the mission hope to provide the primary fuel in 2021.

They argue that their jet fuel could have a a lot smaller CO2 influence then common fuel.

“The beauty of direct air capture is that the CO2 is reused again, and again, and again,” says Louise Charles, from Climeworks, the corporate which offers the direct air seize know-how.

Oskar admits that the fuel has an extended approach to go earlier than it’s aggressive.

“The main element is the cost,” Oskar Meijerink concedes.

“Fossil jet fuel is relatively inexpensive. Capturing CO2 from the air is still a nascent technology and expensive.”

Other corporations are engaged on comparable direct seize methods, together with Carbon Engineering in Canada and US-based Global Thermostat.

But environmental campaigners are extremely sceptical.

“It positive does sound wonderful. It feels like an answer to all of our issues – besides that it is not,” stated Jorien de Lege from Friends of the Earth.

“If you consider it, this demonstration plant can produce a thousand litres a day based mostly on renewable vitality. That’s about 5 minutes of flying in a Boeing 747.

“It’d be a mistake to think that we can keep flying the way that we do because we can fly on air. That’s never going to happen. It’s always going to be a niche.”

While corporations are experimenting with excessive tech methods to seize CO2 from the air, there’s already a quite simple, environment friendly approach to do it – rising crops. And plane are already flying on renewable fuels made from plant biomass.

Sugar cane, grasses or palm oil, and even animal waste merchandise – successfully something that incorporates carbon – can be processed and used.

But are these different fuels are by no means going to interchange conventional fossil jet fuel?

“Yes, however it’s very troublesome to set a timeframe,” says Joris Melkert, senior lecturer in aerospace engineering at Delft University of Technology.
