AIRCO made vodka from CO₂. Now it wants to move the refinery.
A bottle proved the chemistry. Aircraft, boats and military vehicles tested the proposition. AIRCO’s next wager is that making fuel where it is needed can be worth more than shipping it there.
Aether Diamonds made diamonds from air. The margins proved harder.
Aether turned atmospheric carbon into fine jewelry, then ran into the unforgiving economics of lab-grown diamonds. Its story reveals what a climate premium can buy - and what it cannot protect.
Aircapture and the Case of the Missing Bubbles
A brewery can have beer and still have nothing to sell. Aircapture is betting that the shortest route to a better carbon business runs from the air outside a factory to the production line inside it.
StormFisher Bought a $1.5 Billion Clean-Fuel Headache for $17.5 Million - Now It Has to Make the Math Work
A Canadian project developer picked up a stranded Quebec fuel complex at a steep discount, scrapped its original process and bet on e-methanol. The clever part is reuse; the hard part is turning cheap infrastructure into bankable fuel.
Dioxycle
Dioxycle is a French-American climate-tech company building a low-temperature electrolyzer that turns waste CO2, water, and renewable electricity into sustainable ethylene - the world's most-used organic chemical - at a cost competitive with fossil-derived ethylene. Founded in 2021 by electrochemists Sarah Lamaison and David Wakerley, it aims to electrify chemical manufacturing and recycle industrial carbon emissions at gigaton scale.
Sarah Lamaison
Sarah Lamaison is the co-founder and CEO of Dioxycle, a Paris- and Bay Area-based climate-tech company building electrolyzers that turn industrial CO2 into ethylene and other chemicals using only water, electricity, and waste carbon. A chemist trained at Ecole Polytechnique, Cambridge, College de France, and Stanford, she turned her PhD on artificial photosynthesis into a company aiming to decarbonize one of the planet's dirtiest industries while staying cost-competitive with fossil feedstocks. She raised $17M in Series A funding led by Breakthrough Energy Ventures and Lowercarbon Capital, won the L'Oreal-UNESCO Young Talent award, and was named to Forbes 30 Under 30.
