The Carbon Frame: Lobbying for Renewable Energy in the European Union
<p>This paper demonstrates how using the word "carbon" within global warming debates severely impedes lobbyists in favor of building stronger renewable energy policies in the European Union (EU). Within the EU, carbon is widely used to speak about many of the perils of climate change, global …

Design and Optimization of Post-Combustion CO2 Capture
This dissertation describes the design and optimization of a CO2-capture unit using aqueous amines to remove of carbon dioxide from the flue gas of a coal-fired power plant. In particular we construct a monolithic model of a carbon capture unit and conduct a rigorous optimization to find the lowest …

A Pre-Feasibility Assessment of Geologic CO₂ Storage, Offshore Corpus Christi
Carbon capture and storage (CCS) is a technology to capture CO2 emissions from industrial point-source facilities and store the CO2 in deep geological formations in perpetuity. The Gulf of Mexico is a region of interest for CCS development, as it contains laterally extensive reservoir-seal systems …

Underground Britain: public perceptions of the geological subsurface
… at the boundary between two worlds; the visible and the invisible. Increasingly, new geological technologies such as hydraulic fracturing, carbon capture and storage (CCS) and radioactive waste disposal are drawing the public’s attention to the ‘invisible’ world of the geological subsurface. This …

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 …

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 …

Interface pinning of CO₂ gravity currents
Carbon capture and storage (CCS) is widely regarded as a promising tool for reducing global atmospheric carbon dioxide (CO₂) emissions, while allowing continued use of fossil fuels in the 21st century. In CCS, CO₂ is captured at point sources such as coal power plants and injected deep underground …

The subsurface fluid mechanics of geologic carbon dioxide storage
In carbon capture and storage (CCS), CO₂ is captured at power plants and then injected into deep geologic reservoirs for long-term storage. While CCS may be critical for the continued use of fossil fuels in a carbon-constrained world, the subsurface behavior of CO₂ remains poorly understood, which …
