Carbon Dioxide removal from air (CDR) combined with permanent solid storage can be
accomplished via carbon mineralization in ultramafic rocks in at least four ways: 1. Surficial …

The use of hydraulic fracturing techniques to extract oil and gas from low permeability shale
reservoirs has increased significantly in recent years. During hydraulic fracturing, large …

Reactive transport modeling is a process-based approach that accounts for advection,
diffusion, dispersion and a multitude of biogeochemical reactions. The occurrence of these …

Hydrated Mg-carbonate minerals form during the weathering of ultramafic rocks, and can be
used to store atmospheric CO 2 to help combat greenhouse gas-fueled climate change …

Accelerated carbonation of ultramafic mine tailings has the potential to offset CO2 emissions
produced by mining ores from Cu-Ni-platinum group element, podiform chromite …

The Baptiste deposit is located within the Decar nickel district in British Columbia, Canada
and is a promising candidate for a CO 2 sequestration demonstration project. The deposit …

This work comprehensively reviews the equations governing multicomponent flow and
reactive transport in porous media on the pore-scale, mesoscale and continuum scale. For …

Tailings dam failures can cause devastation to the environment, loss of human life, and
require expensive remediation. A promising approach for de-risking brucite-bearing …

CO 2 storage in shale formation is a potential way to reduce CO 2 emissions for carbon
