This website has a very useful interactive comparison tool with data on  24 large CDR focussed projects (Feb 2021).

Addressing the crisis of climate change requires action on several fronts. We now need large-scale deployment of carbon removal alongside critical reductions in emissions. Carbon removal refers to natural or technological approaches for removing carbon dioxide from the atmosphere. We’re a non-profit that analyzes carbon removal opportunities based on the best available science and data. We help organizations make specific decisions towards their carbon removal goals. And we work collaboratively to build open tools and resources for the evaluation and deployment of carbon removal and other climate solutions.”

“We collaborate with researchers to build open source data and tools for carbon removal and climate solutions. Through this work we produce datasets, models, interactive articles, and commentary on climate policies and programs.”


“Carbfix’s carbonated water reacts with the rock underground and elements such as calcium, magnesium and iron are released into the water. With time, these elements will combine with the dissolved CO2 and form carbonates filling up the empty space in the rocks underground. The carbonates are stable for thousands of years and can thus be considered permanently stored. The timescale of this process initially surprised the scientists. In the CarbFix pilot project, it was determined that at least 95% of the injected CO2 mineralises within two years, much faster than previously thought.”

“The theoretical storage capacity of the ocean ridges is significantly larger than the estimated 18,500 Gt CO2 stemming from the burning of all fossil fuel carbon on Earth. The question remains, how much of this theoretical storage capacity is feasible to use for mineral storage of CO2.”

CCS Processes

There are approximately 40 million tonnes/year of CCS capacity operating today (the red bars). According to this paper the potential storage capacity is much greater than is required to  return the atmosphere CO2 concentration down to the pre-industrial level of around 300 ppm.

“STORAGE CAPACITY IS NOT A CONSTRAINT. Geological storage resources for CO2 appear more than sufficient to meet global requirements under any net-zero emissions scenario. However, policy settings do not support a private business case for investment. Government funding of strategic storage resource appraisal programmes is essential.”

Mineral Carbon International  Canberra, Australia

An olivine based solution. “MCi is an Australian clean technology company transforming CO2 emissions into valuable materials that provide profitable decarbonisation pathways for the mining, manufacturing and energy sectors.

MCi transforms CO2 […] into low carbon building and construction products. Our technology provides a novel decarbonisation solution for industry that is not reliant upon carbon pricing, offsets or subsidies.”    “[The method] has a very low process and energy cost, and is adaptable and scalable to integrate into many industrial scenarios such as mineral processing, steel, cement, hydrogen, gas and chemical production.”

Projects to be included: 

  • Carbon cure
  • GreenSand
  • Project Vesta
  • Vandersanden
  • Planetary Hydrogen, USA
