Aerleum, a startup founded by Sébastien Fiedorow and scientist Steven Bardey, aims to revolutionize direct air capture (DAC) by converting captured carbon dioxide directly into methanol fuel. The company has secured $6 million in seed funding to build a pilot device for this technology. Aerleum's process removes the need for traditional DAC steps, allowing for a more efficient conversion of CO2 into fuel. The startup targets a production cost of $650 per metric ton of methanol within five years, positioning itself competitively against fossil fuels.
