Paris — Aerleum, an innovative climate-tech start-up specializing in the capture and use of CO₂, announces the successful completion of its $6 million seed financing led by 360 Capital and HTGF, with participation from Norrsken, Bpifrance and Marble. The funding will accelerate the industrialization of Aerleum’s novel technology that converts atmospheric CO₂ and low-carbon hydrogen into synthetic fuels (e‑fuels) and chemicals, moving sectors that are difficult to decarbonize towards a carbon-neutral future. Aerleum’s breakthrough solution captures CO₂ in a reactor and converts it using proprietary bifunctional materials and precision heating. The company’s technology eliminates some of the most energy-intensive steps in the value chain, enabling competitive, scalable production of e‑fuels and chemicals while dramatically reducing greenhouse gas emissions. Aerleum has set itself the most ambitious target on the market in terms of time to achieve price parity with fossil fuels. The start-up aims to offer industries such as shipping, aviation and chemicals a viable path to decarbonization without compromising on cost or scalability. Sébastien Fiedorow, co-founder and CEO of Aerleum: “Our mission has been clear from the start: to make e‑fuels as affordable and accessible as fossil fuelsWith this seed round, we are taking a big step forward in scaling our technology to meet the urgent need for decarbonization. We intend to transform entire industries and enable them to achieve net zero emissions faster and more efficiently.” Aerleum not only addresses the urgency of the climate crisis, but also solves the economic challenges typically associated with clean energy solutions. Unlike traditional processes, which are costly and location-bound, Aerleum’s innovation can be deployed globally. It optimizes co-location for low-carbon hydrogen sourcing and provides a viable alternative to fossil fuels for industries around the world. Aerleum’s initial focus is on e‑methanol, a clean, high-energy fuel that is rapidly gaining acceptance as an important alternative to fossil fuel in the marine and aviation sectors. E‑methanol offers significant benefits by reducing greenhouse gas emissions, lowering air pollutants and serving as an excellent energy carrier as it remains liquid at ambient temperature, making it easy to transport and store. The global e‑methanol market is expected to grow significantly as the shipping and aviation industries are under increasing pressure to reduce CO2 emissions. Aerleum is well positioned to lead this transformation.
What’s next for Aerleum?
With the seed funding secured, Aerleum will launch its first full-scale pilot plant. 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 in the air becomes a resource,” said Steven Bardey, co-founder and CTO of Aerleum. Recognition and support
Aerleum has already achieved great recognition and won 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 most recently the 2024 i‑lab State Innovation Challenge. The company has received extensive financial support from Bpifrance and the Grand Est region, which has been instrumental in helping Aerleum achieve its milestones. In addition, Aerleum is supported by programs such as Air Liquide’s Accelair, CMA CGM’s ZEBOX and Semia, all of which provide valuable support in scaling the innovative solution. “We were excited by Aerleum’s vision of a world where oil is replaced by CO2 in the air. This vision is anchored in reality, as demonstrated by the first systems and the commercially sound business model, and it paves the way for large-scale applications,” explain Alexandre Mordacq and François Tison of 360 Capital. “What really sets Aerleum apart is the powerful combination of breakthrough technology and a vision to replace polluting chemicals like methanol with a sustainable, carbon-neutral alternative. This vision fits perfectly with HTGF’s commitment to fostering innovation that not only drives business growth, but also contributes to a more sustainable planet. In just one year, the team has demonstrated remarkable speed, execution and significant technical milestones that underscore its ability to scale quickly. We look forward to supporting Aerleum on the next stage of their journey,” says Timo Bertsch from HTGF (photo © TimoBertsch).
