System Dynamics of Carbon Capture and Storage
A techno-economic analysis of carbon capture and storage (CCS) is presented using system dynamics. These models fully couple the CCS subsystems of carbon dioxide (CO2) capture, transport, and storage as an integrated system with feedback and control. Simulations are presented for CO2 captured from …

Public awareness of carbon capture and storage : a survey of attitudes toward climate change mitigation
The Carbon Capture and Sequestration Technologies Program in the Laboratory for Energy and the Environment at MIT conducted a survey of public attitudes on energy use and environmental concerns. Over 1,200 people, representing a general population sample of the United States, responded. The survey …

Leakage of carbon dioxide from a simulated subseabed Carbon Capture and Storage reservoir: potential impacts on benthic biogeochemistry
Carbon Capture and Storage is a nascent technology developed with the intention of collecting carbon dioxide emissions from the flue gasses of point source producers, such as power stations or cement works. The carbon dioxide is then stored in underground geological reservoirs so that it does not …

Strategies for demonstration and early deployment of carbon capture and storage : a technical and economic assessment of capture percentage
Carbon capture and storage (CCS) is a critical technology for reducing greenhouse gas emissions from electricity production by coal-fired power plants. However, full capture (capture of nominally 90% of emissions) has significant impacts on the technology, plant performance, and project economics …
