Aerleum's Series A

Aerleum is a deeptech company turning CO₂ into e-methanol. Our core innovation combines CO₂ capture and conversion in a single integrated reactor, removing the cost and complexity of the multi-step processes used today. The result is a more competitive route to green fuels and molecules, urgently needed by hard-to-abate sectors such as maritime, aviation and chemicals.

We are now opening our €15M Series A to move from the lab to industrial scale.

Use of proceeds

• Scale up from our pilot unit toward first commercial units

• Strengthen the engineering team and de-risk the path to industrial scale

• Advance commercial agreements with off-takers and integration partners

Traction

• Proprietary capture-and-conversion technology validated at pilot scale, with a clear cost advantage over conventional CO₂-to-methanol routes

• Active partnerships and commercial discussions with maritime and aviation players, including a major contract signed with Groupe Aéroports de Paris

• Backed by 360 Capital, HTGF, Norrsken, Bpifrance and Marble

What we are looking for

Investors who bring more than capital: strategic value in industrial scale-up, access to CO₂ sources or off-take, and long-term conviction in e-fuels.
