We're here to put carbon back where it belongs
Terravault is a team of engineers, geochemists, and climate scientists building the removal infrastructure the next century depends on — and holding ourselves to the evidence.
Getting to net zero isn't only about emitting less. Hundreds of gigatons of legacy CO₂ are already in the air. Someone has to take it back out — permanently, measurably, and at a price the world can afford. That's the work we chose.
From a lab bench to a fleet
Founded in Zurich
Two process engineers and a geochemist build the first solid-sorbent prototype in a rented university lab.
First pilot online
Facility 01 begins capturing in Iceland, powered by geothermal heat and storing CO₂ in basalt.
First enterprise offtake
Isometric certification lands; a Fortune 100 buyer signs a multi-year removal agreement.
Gen 3 breaks $180 / ton
A modular redesign cuts cost per ton by 71% versus the first generation.
148,200 tons verified
Four facilities operate across three continents, every ton independently verified.
Principles we build by
Evidence over vibes
If a ton can't be measured and independently verified, we don't sell it. Our credibility is the product.
Permanence, not paperwork
We store carbon as rock. Not trees that can burn, not credits that can double-count. Removal that stays removed.
Scale is the only mercy
A boutique climate solution isn't a solution. Every design decision is judged against gigaton-scale deployment.
Proof, not projections
The people behind the numbers
Come build the removal century
We hire people who want the hardest version of the climate problem. If that's you, we should talk.
