Setting the new standard for synthetic fuels.

Aerleum® develops a breakthrough technology that captures and converts atmospheric CO₂in a single reactor. By removing the most energy-intensive steps and intermediate processing, our system produces low-carbon fuels and chemicals with the cost and performance needed to compete head-on with fossil fuels.

Introducing Direct Carbon Utilisation
Reactive Adsorbent
Our materials are dual-functional: they capture CO2 through adsorption and convert it directly into a target molecule — all on the same support.
Single Reactor
Designed for carbon capture and conversion in a single unit, our custom reactor is engineered for scale, versatility, and efficiency.
Precision Heating
A process heated in less than a minute? Yes, fast heat and instantaneous on/off switch. It's really suited for what we're doing.

A modular pilot at ton scale.
1 ton of e-methanol by Aerleum® is:
A cost on par with fossil methanol price

20× lower carbon footprint than coal-based methanol

35% more energy-efficient than traditional processes
Some questions
What makes CO2-based methanol a viable alternative to fossil fuels?
Methanol is already widely used as a fuel, solvent, and chemical feedstock — with global infrastructure in place. By producing it from captured CO2 and green hydrogen, we enable a drop-in replacement that can significantly reduce lifecycle emissions while targeting cost parity with fossil-based methanol.
How is Aerleum’s technology different from traditional CO2 utilization processes?
Unlike conventional approaches that separate capture and conversion, Aerleum’s system uses a reactive sorbent that does both — it captures CO2 and converts it in situ. This integrated process eliminates costly intermediate steps, improves energy efficiency, and simplifies deployment.
Who is Aerleum built for — and where can your solution be deployed?
We focus on hard-to-abate sectors like maritime, heavy transport, and chemicals — where fossil dependence is still dominant and alternatives are scarce. Our modular system can be deployed at industrial point sources or integrated into clean infrastructure projects, anywhere on the map.
How do you source your energy and hydrogen?
Our system is designed for maximum siting flexibility. We co-locate directly where low-carbon hydrogen is produced under optimal conditions — whether that’s near renewables, electrolysis hubs, or industrial clusters.
By using hydrogen on-site, we significantly cut distribution and compression costs, which are major barriers to adoption. This also supports the development of hydrogen infrastructure where it makes the most economic and climate sense — close to cheap, clean energy sources.
Do you use CO2 from the air or from industrial sources?
Our technology is designed to flex between both, depending on the use case, economics, and climate impact goals.
For now, we’re focusing on atmospheric CO2, as it offers a clean, independent, and abundant carbon supply — especially valuable when co-locating with low-carbon hydrogen hubs.
That said, point-source CO2 remains highly relevant in contexts where it's concentrated and cost-effective.
