Forscher haben ein neues katalytisches System entwickelt, das in der Lage ist, Kohlendioxid in industriell sinnvollen Maßstäben in nutzbaren Kraftstoff umzuwandeln und während der Tests Berichten zufolge etwa 110 Pfund Kraftstoff pro Tag zu produzieren. Wissenschaftler sagen, dass Technologien wie diese letztendlich dazu beitragen könnten, abgeschiedenes CO2 in sauberere Kraftstoffe für Sektoren zu recyceln, die sich nur schwer vollständig elektrifizieren lassen, darunter die Luftfahrt und die Schifffahrt.

This is the kind of future technology I find genuinely exciting because it feels practical instead of purely theoretical.
A lot of climate discussions become very doom-focused, so it’s interesting seeing research aimed at turning waste carbon back into something useful instead of only talking about reducing emissions. Obviously this alone is not going to magically solve climate change, but if systems like this become scalable it could completely change how industries like aviation or cargo shipping operate in the future.
The idea of pulling carbon from the atmosphere and turning it back into fuel still sounds a little sci-fi honestly.
See what happens when the USA can’t get that oil. The entire planet leap frogs in technology.

2. Turning CO2 into fuel is neither new nor hard. The problem is that it’s not practical to pull it from air to do that and if you already have electric energy you might as well use it as is or, in the worst case scenario, use it for water electrolysis and either make hydrogen or ammonia.
Climeworks is doing direct air capture at commercial scale today. https://climeworks.com/projects
It is indeed incredible technology. One concern with these kind of technologies is always:
Efficiency.
To pull carbon out of the air, and make fuel, you need to add energy. If this energy is created by use of a fossiele fuel, it is almost guaranteed that the co² released by the energy plant is higher than the captured co² of the converter.
Then the argument becomes:
We will use solar power, or wind power!
But then, you can argue that: if you used that solar panel just to use less energy from the grid, it would have saved more co² than using it for the converter.
Then the next argument is:
Let’s use the device when there is excess energy from solar and wind!
Which results in an increadebly low operating window for the converter, and the co² released to build the device will never be captured within the lifespan of the converter.
Although It is a difficult use case at the moment, it of course can become useful in the future maybe.
As per the article, this new methods turns a mixture of CO2 and HYDROGEN into fuel. That is not new. The sensationalist new is probably a hyperbole based on a real, but more modest, catalyst that makes this well-known reaction more effective.
But the real problems here are the costs of making hydrogen, and the cost of extracting CO2 from the athmosphere.
In my opinion, the real turning points that give me hope are nuclear and solar electric production, battery and electric motor technologies, and to a lesser extent non-crop based biofuels.
For now, the most efficent way to store CO2 out of athmosphere is to grow plants. If cou want that CO2 to be out of the athmoshere for ever, you then burn the plants and store the CO2 underground. The advantages are that 1. by growing plants and then burning them, you concentrate the CO2 in a way that is more efficient than any known technological method, 2. when you burn them, you produce heat, that can be used for home heating and for electricity production. You can sell that and make the operation less costly or even costless depending on the local energy market. 3. when CO2 is injected deep underground, it reacts with the rocks and can bind with them, so, there is no leak risk, your CO2 is effectly stored for a geologic amount of time.
so you pull it out of the atmopshere just to burn it and put it back there? Most useless shit i’ve seen in a while.
