Regulating the Geological Sequestration of CO 2

Geomechanical modeling for CO2 storage in Nisku aquifer in Wabamun Lake area in Canada

“…Conservation of energy, improving end-use efficiency and increased use of renewable energy has potential to contribute to a portfolio of a low-emission power generation. However, due to the associated significant technical and economical barriers such as the inherent intermittent nature of the renewable energy and incompatibility with the current fossil fuel energy infrastructure, these measures may not result in large cuts in CO 2 emission for decades to come (Wilson et al, 2008). Based on experience gained from existing sequestration pilot projects and enhanced oil recovery practices, geologic storage has proved to be a technically viable means to significantly reduce anthropogenic emissions of CO 2 (Solomon, 2006;Preston et al, 2005;Wright, 2007).…”

An evaluation of ex situ, industrial-scale, aqueous CO2 mineralization

“…CCS offers the potential for continued use of fossil fuels with reduced CO 2 emissions, and a variety of CCS demonstration projects are currently underway (Herzog, 2011). However, the sequestration of CO 2 in geological formations faces a number of challenges including public perception, the potential for CO 2 escape, the requirement for long-term site monitoring and liability (Wilson et al, 2008;Herzog, 2011;IPCC, 2005). Consequently, aqueous mineral carbonation has been proposed as a strategy to permanently sequester CO 2 and even to potentially produce beneficial products, without the associated long-term monitoring and liability issues.…”

Carbon capture and storage policy in the United States: A new coalition endeavors to change existing policy

“…Proponents of CCS as a climate mitigation technology identify the lack of legal and regulatory frameworks as a barrier to its deployment (Bachu, 2008;Wilson et al, 2008;Metz et al, 2005). However, in the U.S., the problem is not the absence of regulation; rather, it is the existence of a mature policy regime devoted to the injection of CO 2 into deep geologic formations for enhanced oil recovery (EOR), which does not manage the risks and benefits of CO 2 injection as a means of avoiding GHG emissions.…”
