Geologic Carbon Containment
Advancing Permanent Geologic Carbon Containment Methods
The CC Lab is currently investigating options for carbon storage in the U.S. via geologic storage and mineralization. Carbon mineralization is the process by which CO2 becomes a solid mineral, such as a carbonate, and is therefore permanently stored. For instance, CO2 left to interact with basalt has been shown to mineralize in as few as two years.1 Experiments suggest that through the process of CO2 mineralization, one cubic kilometer of basalt can permanently store as much as 47 million MTCO2e.2
The Carbon TrapRock Project
Through its Carbon TrapRock project, the CC Lab is currently investigating the potential to help develop a portfolio of low-cost injection wells to store carbon permanently and safely deep in the Columbia River Basalt Group (“CRBG”).3 The CRBG spans 210,000 km2 across the Pacific Northwest. Its basalt composition, as well as its large size, make it well-suited for large-scale CO2 geological storage — with the potential of sequestering up to 100 billion MTCO2e.4
- The science and speed of the mineralization process
- The CRBG resource from the perspective of carbon storage
- The regional potential of sourcing, capturing and transporting CO2
- Permitting processes, policies and incentives
- The environmental, economic and social impacts and benefits across the lifecycle of the project.
As the Carbon TrapRock project is potentially large, the CC Lab is assembling a team of advisors and entrepreneurs that will support its development. In addition, the CC Lab is beginning to investigate storage opportunities in other geologic formations and regions across the U.S.
Existing analyses estimate that the CRBG has the potential to permanently store between 10 and 100 billion MTCO2e.
