In 2013, the Pacific Northwest National Laboratory led a geologic carbon sequestration field
demonstration where∼ 1000 tonnes of CO2 was injected into several deep Columbia River …

Fossil fuels account for more than 90% of the world total energy consumption. The emission
of CO 2 to the atmosphere can be reduced by the development and implementation of …

CO~ 2~ trapping mechanisms in geologic sequestration are the specific processes that hold
CO~ 2~ underground in porous formations after it is injected. The main trapping …

Like it or not, coal is here to stay, for the next few decades at least. Continued use of coal in
this age of growing greenhouse gas controls will require removing carbon dioxide from the …

Leakage of CO2 and brine from geologic storage reservoirs along wellbores is a major risk
factor to the success of geologic carbon sequestration. We conducted multiphase …

Hydraulic fracturing employs a mixture of freshwater and chemical additives. Substituting
produced formation water for freshwater conserves freshwater resources, but formation …

Dissolution of CO 2 into deep subsurface brines for carbon sequestration is regarded as one
of the few viable means of reducing the amount of CO 2 entering the atmosphere. Ions in …

Carbon dioxide injection in porous reservoirs is the basis for carbon capture and storage,
enhanced oil and gas recovery. Injected carbon dioxide is stored at multiple scales in …

We present a new polarizable force field for aqueous ions (Li+, Na+, K+, Rb+, Cs+, Mg 2+,
Ca 2+, Sr 2+, and Cl−) derived from condensed phase ab initio calculations. We use …

To ensure the effective long-term storage of CO 2 in candidate geological storage sites,
evaluation of potential leakage pathways to the surface should be undertaken. Here we use …
