# FlueVault

##### ACCELERATING THE RATE OF CLIMATE INNOVATION BY:

Redefining the carbon capture and storage (CCS) value chain. FlueVault’s breakthrough technology reduces CCS costs by up to 50% while producing green nickel and chromium — critical metals for batteries and clean energy technologies.

[Carbon Capture and Utilization](https://www.third-derivative.org/portfolio/tag/carbon-capture-and-utilization) [Negative Emissions](https://www.third-derivative.org/portfolio/tag/negative-emissions) [Cohort 24-2](https://www.third-derivative.org/portfolio/tag/cohort-24-2) [Negative Emissions - Ocean CDR](https://www.third-derivative.org/portfolio/tag/negative-emissions-ocean-cdr)

##### PROBLEM FOCUS

CCS remains prohibitively expensive because it requires ultra-pure (>99%) and dry CO₂ streams that must be liquefied and transported to remote storage sites. At the same time, global critical metals supply of nickel and chromium is heavily concentrated in China, Russia, and Indonesia, creating a major supply chain bottleneck with both security and sustainability risks. FlueVault tackles both problems at once — lowering CCS costs and securing resilient supplies of critical green metals. 

##### TECHNOLOGY SOLUTION

FlueVault’s continuous seawater system co-dissolves industrial CO₂ with abundant fine-grained olivine, permanently converting CO₂ into stable bicarbonates. The process simultaneously releases nickel and chromium, which are then captured and refined into high-purity metals for clean energy applications, like batteries. The result is a single process that makes CCS affordable while unlocking a renewable source of critical materials for the energy transition.
