Article Synopsis
- Capturing and storing CO(2) emissions underground is a method being explored to mitigate atmospheric CO(2) levels, but it bears environmental risks such as potential leakage and groundwater contamination.
- A field study was conducted to observe the effects of dissolved CO(2) on groundwater, finding that it significantly lowered pH levels by about 3 units without raising the concentration of harmful trace elements like As and Pb above detectable limits.
- Various inorganic constituents showed initial spikes in concentration before returning to background levels, indicating quick release processes, while EPA-regulated substances remained within safe limits throughout the study.
Even before technology matures and the regulatory framework for carbon capture and storage (CCS) has been developed, electrical utilities will need to consider the logistics of how widespread commercial-scale operations will be deployed. The framework of CCS will require utilities to adopt business models that ensure both safe and affordable CCS operations while maintaining reliable power generation. Physical models include an infrastructure with centralized CO(2) pipelines that focus geologic sequestration in pooled regional storage sites or supply CO(2) for beneficial use in enhanced oil recovery (EOR) and a dispersed plant model with sequestration operations which take place in close proximity to CO(2) capture.
