Could mineralization, a natural process for carbon sequestration, be accelerated ?

The way to a sustainable future:
reduce and remove

The science is clear: in order to avoid a catastrophic future, we need to limit the average global warming to 2°C. This trajectory requires that we reach net-zero emissions by 2050.

The net-zero emissions goal requires to complementary pathways.

First, we need to drastically reduce our emissions of CO2, and more largely of all greenhouse gases.

Then, we also need to remove excess CO2 already present in the atmosphere. Removing CO2 from the atmosphere, or carbon removal, is a mechanism present in nature, through carbons sinks.

“All analysed pathways limiting warming to 1.5°C [...] use Carbon Dioxyde Removal to some extent to neutralize emissions from sources for which no mitigation measures have been identified [...].”
IPCC Sixth Assessement Report

Carbon sinks: Our best allies

Nature has its own way to regulate carbon present in the atmosphere. Carbon sinks are deposits that store CO2 and prevent it to reaching the atmosphere.
But relying only on natural carbon sinks has its drawbacks: forests can massively CO2 in case of a fire, oceans acidify if they store too much CO2...
We need to protect and restorate these ecosystems to help them store CO2: planting trees, protecting the oceans, revitalizing the soils are all part of the roadmap to a better future.
We need to research and deploy safe ways to help nature in this process.

The olivine: a carbon sink that rocks!

Olivine is a volcanic mineral widely abundant on earth, that already serves naturally as a carbon sink. For example, some beaches in Hawaii have olivine sand, that captures large amount of CO2.

By spreading olivine on chosen sites, we could sequestrate billions of tons of CO2.
Mineral carbon removal already exists everywhere on our planet. When rain falls over volcanic rocks, a naturally occuring chemical process stores the CO2 in the rocks.
Nature is the best teacher.
With mineral carbon removal, the CO2 stays locked in rocks. Planting trees and regenerating soils is of course also needed, but they are a less permanent solutions as CO2 can re-enter the atmosphere, in the event of a forest fire for example.
Olivine makes up to the half of the upper mantle on earth and is available on every continent, making it easily accessible.

Our roadmap

Phase 1: Research
Fondational research for this project has been led by a global consortium of scientists. Understand and modeling all aspects of the solution is crucial to ensure that the solution will be both efficient and perfectly safe.
Phase 2: Pilot projects
Pilot projects allows to study in real life the impact of spreading olivine at small and carefully chosen sites.

These pilot projects will allow to study the in-situ impact of olivine on its environment but also the efficiency of the carbon capture.
Phase 3: Scaling Up
If the pilot trials are successful, the next was will be to scale up olivine deployment.

Potential use cases

When spreading olivine and coastal sites, we can harness the power of the sea: the waves naturally erodes the olivine, creating the reaction that stores carbon. Moreover, olivine as be proven to de-acidify the ocean, having a positive impact on this ecosystem
Agricultural sites, such as vineyards
Adding olivine to agriculture sites allows to enhance the carbon sequestration properties of the soil
“Vacant” lands, such as train line
Various pieces of land can’t be used for agriculture of plating trees, since they are already used by infrastructures such as train lines. However, these lands are perfect candidates for olivine spreading
