Aerleum, a pioneering climate tech company specializing in CO₂ capture and utilization, announces the successful close of its $6M seed round, led by 360 Capital and HTGF, with participation from Norrsken, Bpifrance, and Marble.
The funding will accelerate the industrialization of Aerleum’s breakthrough technology, which transforms atmospheric CO₂ and low-carbon hydrogen into synthetic fuels (e-fuels) and chemicals, propelling hard-to-abate sectors toward a carbon-neutral future.
Aerleum’s game-changing solution captures and converts CO₂ in a single reactor, using proprietary bifunctional materials and precision heating. The company’s technology eliminates some of the most energy-intensive steps of the value chain, enabling cost-competitive, large-scale production of e-fuels and chemicals, while drastically cutting greenhouse gas emissions.
Aerleum is setting the fastest timeline in the market to achieve price parity with fossil fuels, offering industries—such as maritime, aviation, and chemicals—a viable path to decarbonization without compromising on cost or scalability.
"Our mission has been clear since the beginning: to make e-fuels as affordable and accessible as fossil fuels. With this seed round, we’re taking a major step forward in scaling our technology to meet the urgent demand for decarbonization. We’re here to reshape entire industries, enabling them to achieve net-zero emissions faster and more efficiently", Sébastien Fiedorow, co-founder & CEO of Aerleum
Aerleum not only addresses the urgency of the climate crisis but also solves the economic challenges typically associated with clean energy solutions. Unlike conventional pathways that remain costly and limited by location, Aerleum’s innovation is ready to scale globally, optimizing co-location for low-carbon hydrogen sourcing and providing industries around the world with a viable alternative to fossil fuels.
Aerleum is initially focusing on e-methanol, a clean, energy-dense fuel that is rapidly gaining momentum as a key alternative in the maritime and aviation sectors. E-methanol offers significant benefits by reducing greenhouse gas emissions, cutting air pollutants, and serving as an excellent energy carrier as it remains liquid at ambient temperature—making it easy to transport and store. With the global e-methanol market projected to grow significantly as the maritime shipping and aviation industries face increasing pressure to decarbonize, Aerleum is well-positioned to lead this transformation.
What’s Next for Aerleum?
With the seed funding secured, Aerleum is poised to launch its first full-scale pilot unit. The company will work closely with key industry players and customers to deploy its technology in sectors where emissions reductions are critical.
"Aerleum’s vision is to transform industries and create a circular carbon economy, where the CO₂ present in the air becomes the resource", said Steven Bardey, co-founder & CTO of Aerleum.
Recognition and Support
Aerleum has already gained significant recognition, winning prestigious awards including the CMA CGM “Climate Innovation Challenge” Award, the Technip Energies “Clean Maritime Challenge”, the EDF Pulse 2024 Challenge, the Prix Pépite, and more recently the 2024 i-lab state innovation challenge. The company has received strong funding support from Bpifrance and the Région Grand Est, which has been instrumental in helping Aerleum achieve its milestones.Furthermore, Aerleum is being accelerated through programs such as Accelair by Air Liquide, ZEBOX by CMA CGM, and Semia, all of which provide invaluable support in scaling its innovative solutions.
Alexandre Mordacq and François Tison from 360 Capital quoted that "We were seduced by Aerleum’s vision of a world where petroleum would be replaced by the CO2 present in the air – a vision rooted in reality as demonstrated by their first systems, and their economically sound business model opening the way to large scale applications."
