CO2 capture viability
DOE awards SRI $4.5 M to evaluate viability of CO2 Capture
SRI International, an independent nonprofit research and development institute, has been awarded a $4.5M Department of Energy (DOE) project to evaluate the technical and economic viability of CO2 capture using an ammonium carbonate-ammonium bicarbonate (AC-ABC) process at gasification plants, including IGCC power plants.
This new project is one of several projects at SRI aimed at finding cost-effective ways to recover carbon dioxide from power plants so it can be sequestered.
One of the advantages of the AC-ABC process is that it removes CO2 and hydrogen sulfide at pressure, resulting in less energy needed to capture the CO2. In addition, the AC-ABC approach has the potential to be commercialized at a low cost and in a relatively short amount of time because it does not require the development of novel materials, solvents, or reactor configurations.
A variety of approaches to carbon capture is needed to address both current and future power plant designs. Results from this DOE-funded project can also be applied to other types of power plants that require carbon dioxide removal pre-combustion, such as hydromethanation plants.

It is convincing that capturing carbon dioxide prior to combustion is the simplest and lowest cost solution for eliminating greenhouse gas emissions on a large scale.
CCS is not commercially viable. The only way to make it commercially viable is to internalize the cost of CO2 emissions to such a degree that the cost of investing in the infrastructure for capturing the CO2 justifies the investment.
Widespread use of CCS will mean that we value environmental/ecosystem services more than energy services on a larger scale than any time before in history of human civilization.
Carbon capture and sequestration (CCS) can be an important component of reducing worldwide CO2 emissions from stationary point sources, such as coal-fired power plants. Aqueous amines and ammonia are being demonstrated for CO2 capture in a temperature swing cyclic process.
