Geologic carbon storage possibilities in the Pacific Northwest

Addressing climate change requires a global effort to reduce carbon dioxide (CO₂) emissions, and to capture and store billions of tons of atmospheric CO₂ per year. Once captured, some of that CO₂ can be recycled in evolving and inventive technologies for industrial processes and products. But we produce far more CO₂ than we require, and a large proportion of that CO₂ will need to be stored. Geologic carbon storage, in saline aquifers or depleted reservoirs, or mineralized in mafic or ultramafic rocks, will be a key technology in locking carbon away long-term. Here we take a look at the types of geologic carbon storage currently employed elsewhere, and where and how Oregon’s geology could contribute to carbon removal, with particular focus on CO₂ mineralization in the Columbia River Basalt Group.
