Project Vesta

This rock could help reverse climate change.

Our mission is to help reverse climate change by turning a trillion tonnes of CO2 into rock.

Nature,
accelerated.

We're accelerating Earth's natural process for carbon sequestration: the carbonate-silicate cycle.

Did you know 99.9% of Earth's CO2 is stored in rock?

Most of Earth’s carbon — about 65,500 billion metric tons — is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.

As rain falls on volcanic rock, a chemical process removes C02 from the atmosphere.

Through the natural process of weathering, rocks are dissolved by rain, slowly transporting carbon through waterways and into the ocean - where CO2 is permanently fixed into rock.

This is how our planet has naturally captured the CO2 emitted by volcanoes over geological time.

Olivine is the perfect rock for the job.

Olivine is a widely abundant volcanic mineral. It makes up over 50% of the Earth's upper mantle, and is the most effective mineral for enabling CO2 removal through rock weathering.

Wave goodbye to excess C02.

Capturing a trillion tonnes of excess CO2 in rock using the power of natural wave energy.

Naturally, rainfall erodes volcanic rock, drawing olivine into the oceans.

Through the natural process of weathering, rocks are transported through waterways and into the ocean, where, as part of the long-term carbon cycle, trillions of tonnes of CO2 are permanently stored in rock. This process takes place over 100-200 million years.

The problem is, humanity is releasing CO2 far faster than the planet can re-absorb it.

We can accelerate this process by directly mining olivine, crushing it, and spreading it along coastal shorelines.

Project Vesta’s approach, called Coastal Enhanced Weathering, dramatically accelerates Earth's long-term CO2 removal process.

The abundant energy of wave action along our coastlines helps olivine weather faster.

We acquire  olivine and transport it to beaches, where the free energy of wave action is harnessed to crush the rock and speed up the natural carbon dioxide capture process. This process simultaneously de-acidifies the local ocean environment.

This is big…

A nature-based, permanent, scalable, and affordable solution to climate change.

It's permanent.

Through coastal enhanced weathering, carbon dioxide stays locked in rocks for millions of years.

vs. Forestry

We love trees, and want many more of them planted. But they require lots of arable land, and the carbon they capture is released if they ever burn.

vs. Agriculture

Regenerative agriculture is mandatory for a healthy future, but it's not enough to count on as a carbon sequestration method: it's not permanent, and it demands a lot of land.

vs. Direct Air Capture

DAC is impressive, but expensive. Plus, when DAC is productized, it often puts carbon back into the atmosphere or into waste streams.

It's scalable.

Capture 100% of humanity's annual C02 emissions with only 2% of shelf seas.

Efficient

Coastal Enhanced Weathering utilizes the free energy of waves to grind and crush the olivine.

Turn-Key

We don’t need any clever new technology breakthroughs... It's ready for development now.

Abundant

Available on every continent and making up over 50% of the upper mantle, olivine is globally abundant and accessible.

It's smart.

Sequester carbon for
as little as $21 / tonne.

AFFORDABLE

At full scale, costs less than 10% of the price of other carbon capture technologies.

LEVERAGED

For every tonne of CO2 emitted in the process of extraction and transportation of olivine, 20 tonnes of CO2 are removed from the atmosphere (~95% efficiency).

BENEFICIAL

Coastal Enhanced Weathering can also support de-acidification in the local ocean ecosystem.
