CO2 mineralization


CO2 weathering and mineralization is the processes by which certain minerals react with and form a bond with CO2, removing it from the atmosphere by creating an inert carbonate rock.

Carbon mineralization occurs naturally in alkaline environments. Atmospheric CO2 reacts with rocks that are rich in magnesium and calcium, such as basalt, to form solid carbonates. Mineralization is fast on a geological timescale and can be replicated in different environments to capture carbon.

Mineralisation is an appealing pathway for carbon removal as it has a low risk of additionality, a very low risk of carbon leakage and stores carbon very stably.

Adapted from the World Economic Forum Net-Zero to Net-Negative: A Guide for Leaders on Carbon Removal. Available here

Potential removal capacity

Early estimates speculate that enhanced mineralisation could store 2–4 giga-tonnes of carbon globally per annum, with current annual emissions reaching 60 gigatonnes last year.

There are a broad range of different applications for CO2 mineralisation. These fall into three categories:

  1. In-situ processes- sending CO2 rich fluids underground to react with alkaline minerals below the surface
  2. Surficial processes- encouraging enhanced mineralisation by sprinkling alkaline rocks onto land
  3. Ex situ processes- locking CO2 into industrial wastes or new products, like cement

Given these of different applications, there are many different sequestration opportunities currently at very different price points.

🪨 Innovative projects

  • To date, Carbfix have successfully stored over 70,000 tons of mineralized CO2 at their injection site in Hellisheiði, Iceland
  • CarbonCure, a Carbon XPRIZE finalist based in Nova Scotia, Canada, injects CO2 into concrete during the concrete curing process
  • Blue Planet Ltd, located in California, dissolves CO2 from flue gas to form aggregate products, ranging from gravel to sand

💸 Commercial implementation

The Future Forest Company are pioneering mineral weathering in Scotland. They begin by buying degraded land and restoring it back to health using agroforestry methods, such as rotational livestock grazing.

They then sequester further carbon by spreading basalt fines (small particles of basalt rock) over the forest land.

As rainwater falls, it reacts with the basalt to raise the pH of the soil system. As the pH rises, CO2 dissolved in the rainwater turns into carbonates, that form solid minerals like calcium carbonate.

🐳 Offset whales


Swedish fintech firm Klarna spent $415,000 on 1,991 tons of carbon removals in October 2021:

  • 1846 tonnes from 2 biochar projects for $200k, delivering offsets by 2023
  • 147 tonnes from 2 direct air capture (DAC) projects. These cost substantially more a ton ($903 and $2055) totalling $215k, delivering benefits by 2028 and 2024 respectively

Blockchain technology for digital building energy performance MRV and carbon market engagement

A recent paper by Woo et al. in the Journal of Building and Environment explores how digital blockchain MRV can “significantly decrease existing barriers and increase the quality of data” in the building sector.

This is achieved by:

  • Reducing the time and cost by using IoT sensors to collect data
  • Using smart contracts to enhance data quantification and the reporting process
  • Driving greater data accuracy and conformity, enhancing verification processes
  • Creating the opportunity to convert data into the issuance of carbon credits

Blockchain technology can then also be used to enable the tokenisation of these credits, enabling projects to benefit from transparent exposure to the voluntary carbon market.

Additionally, private and public net zero commitments can be audited and monitored by its stakeholders for increased accountability.

Enhanced MRV for forest protection in Tanzania

Last week the Open Forest Protocol announced a partnership with Kisampa Conservancy, a community-driven effort to conserve tree diversity and rewild degraded land in Tanzania.

The Protocol seeks to create an open and global community of forestation project operators, validators and funding partners, enhancing MRV and carbon market engagement. The Conservancy will help test and raise awareness of the Protocol for other organizations looking to do the same with their forest resources.

Building the home of regenerative finance

Regenerative finance, known as ReFi, is a hot topic buzzing in the crypto/ climate space. The ReFi movement is working to redesign money so that it's flow systematically regenerates natural capital assets for the purpose of realizing three core objectives:

  1. Stabilizing our climate by mitigating and sequestering carbon emissions
  2. Restoring our ecosystems by cultivating biological diversity
  3. Instituting social justice by enabling inclusive, community driven engagement

The Open Forest Protocol explored above is one such example that speaks to all three of these objectives.

A vibrant community is just launching that you can become a part of! To learn more, check out the ReFi projects listed at climatecrypto.xyz and follow ReFi DAO on Twitter for news and updates on podcasts and events.
