“…To curb CO 2 emissions, CO 2 capture and sequestration options are being actively studied. Among various options for capturing and concentrating CO 2 from flue gases, absorption by mineral sorbents at high temperatures appears to be attractive [1][2][3][4][5].…”

“…The sorbent can be regenerated by decomposing the CaCO 3 into CaO and CO 2 in a separate reactor (calciner) via calcination, the reverse reaction of Reaction (1). The heat for calcination can be supplied by burning high-carbon fuel with pure oxygen.…”

“…In discussions of enhancing silicate mineral weathering to facilitate carbon storage, Mg-silicate minerals are often targeted for two critical reasons: (1) Mg-silicate minerals are found in more concentrated and larger deposits than are Ca-silicate minerals (Goff et al 2000;Yegulalp et al 2001) so they are more accessible for large scale mining, and (2) Mg-silicates are more reactive than Ca-silicates (Herzog 2002;Yegulalp et al 2001). Despite the apparent interchangeability of Mg and Ca silicates for some of these proposed engineered processes, it is important to recognize the distinctions between the ultimate fate of weathered Ca and Mg.…”

The challenge of reversing rising atmospheric CO 2 concentrations is growing with the continued expansion of CO 2 -emitting energy infrastructure throughout the world and with the lack of coordinated, effective measures to manage and reduce emissions. Given this situation, it is prudent for society to explore all potential carbon management options, including those with seemingly low probability for success. Recent initiatives for advancing and enhancing carbon storage options have focused primarily on the physical trapping of CO 2 in underground geologic formations and on the biological uptake of CO 2 ; less attention has been given to approaches that rely primarily on geochemical reactions that enhance transformation of CO 2 gas into dissolved or solid phase carbon by liberating cations to neutralize carbonic acid. This paper provides a structured review of the technical status of these geochemical approaches, and also presents a simple framework for assessing the potential and limitations of various proposed geochemical approaches to assist prioritizing future research in this area. Despite major limitations, geochemical approaches have unique potential to contribute to CO 2 reductions in ways that neither physical nor biological carbon storage can by allowing for the direct removal of CO 2 from the atmosphere with minimal requirements for integrating with existing infrastructure. Recognizing the severity and urgency of the need for carbon management options, we argue for an increase in research activity related to geochemical approaches to carbon management.

“…We believe, however, that pricing carbon will spur a concerted effort to reduce these costs (Newell et al 2006). This would likely lead to new advanced power plant designs that fully integrate CO 2 capture into the process design and which eliminate virtually all emissions to the atmosphere while greatly improving energy conversion efficiencies (Yegulalp et al 2001). Similar strategies for the designs of zero emission cement, steel and fertilizer plants would eventually lead to the capture of nearly all CO 2 emissions from concentrated sources.…”

In order to meet the challenge of climate change while allowing for continued economic development, the world will have to adopt a net zero carbon energy infrastructure. Due to the world's large stock of low-cost fossil fuels, there is strong motivation to explore the opportunities for capturing the CO 2 that is produced in the combustion of fossil fuels and keeping it out of the atmosphere. Three distinct sets of technologies are needed to allow for climate neutral use of fossil fuels: (1) capture of CO 2 at concentrated sources like electric power plants, future hydrogen production plants and steel and cement plants;(2) capture of CO 2 from the air; and (3) the safe and permanent storage of CO 2 away from the atmosphere. A strong regime of carbon accounting is also necessary to gain the public's trust in the safety and permanence of CO 2 storage. This paper begins with an extensive overview of carbon capture and storage technologies, and then presents a vision for the potential implementation of carbon capture and storage, drawing upon new ideas such as air capture technology, leakage insurance, and monitoring using a radioactive isotope such as C-14. These innovations, which may provide a partial solution for managing the risks associated with long-term carbon storage, are not well developed in the existing literature and deserve greater study.
