Our company
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.
Founded in Zurich in 2019. Four facilities today. One mission that hasn’t changed.
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.
Our story
From a lab bench to a fleet
2019
Founded in Zurich
Two process engineers and a geochemist build the first solid-sorbent prototype in a rented university lab.
2021
First pilot online
Facility 01 begins capturing in Iceland, powered by geothermal heat and storing CO₂ in basalt.
2023
First enterprise offtake
Isometric certification lands; a Fortune 100 buyer signs a multi-year removal agreement.
2024
Gen 3 breaks $180 / ton
A modular redesign cuts cost per ton by 71% versus the first generation.
2025
148,200 tons verified
Four facilities operate across three continents, every ton independently verified.
Inside the plant
Boring, repeatable engineering — running around the clock.
What we believe
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.
Success so far
Proof, not projections
