Building a future where energy and materials no longer rely on fossil fuels, but on CO₂, from air to industry. Beyond alternatives, Aerleum rewrites the baseline: clean, scalable, competitive.

Problem

The race to decarbonize hard-to-abate sectors is on, yet clean, cost-competitive synthetic fuels remain out of reach. Renewable methanol is emerging as a strategic alternative, but supply falls far short of soaring demand. And its cost remains up to 5× higher, due to fragmented value chains, energy-intensive processes, and limited access to renewable CO₂. Meanwhile, regulatory and commercial pressure keeps mounting from zero-emission mandates in shipping to brand-driven decarbonization strategies across industries.

Solution

Aerleum integrates CO₂ capture and conversion in a single reactor, eliminating energy-intensive steps and slashing production costs. Our modular system delivers clean methanol with up to 2x higher energy efficiency and a carbon footprint 90% lower than fossil fuels. By reaching cost parity with fossil-based methanol and performance on par with existing industrial fuels, Aerleum removes key barriers to adoption, paving the way for synthetic fuels to scale where they’re needed most.
