Item Attitudes on Carbon Capture and Storage (CCS) as a Mitigation Technology within the UNFCCC(2021) Romanak, Katherine; Fridahl, Mathias; Dixon, TimCarbon Capture and Storage (CCS) is a technology for mitigating emissions from large point- source industries. In addition to the primary role of reducing carbon dioxide (CO2) in the atmosphere, CCS forms the basis for two large-scale negative emissions technologies by coupling geologic CO2 storage with bioenergy (BECCS) and direct air carbon capture (DACCS). Despite its inclusion within the United Nations Framework Convention on Climate Change (UNFCCC), CCS has been largely unsupported by UNFCCC delegates because of its association with fossil fuels. We evaluate data from surveys given since 2015 to UNFCCC delegates at the Conference of the Parties (COPs) to ascertain how attitudes about bioenergy, BECCS, and CCS may be changing within the UNFCCC. The results show a positive change in attitudes over time for both fossil CCS and BECCS. Using a unique data analysis method, we ascertain that, in some instances, popularity of BECCS increased due to an increased acceptance of CCS despite lower opinions of bioenergy. Business and research NGOs have the most positive views of CCS, and environmental NGOs the most negative views. Delegates that attend CCS side-events have more positive attitudes towards CCS than non-attendees. Developing countries have a larger need and a greater appetite for information on BECCS than developed countries, but a need for information exists in both.Item Bureau of Economic Geology Scientist Recognized for Greenhouse Gas Mitigation Technology(2018-11-15) Moskal, EmilyItem Cast Your Vote for the Art of CCS!(2015-10-15) Berwald, JuliItem Creating a Carbon Capture and Storage Industry in Texas(LBJ School of Public Affairs, The University of Texas at Austin, 2007-02) Eaton, David; Duncan, IanReport on the potential for industrial development of geologic sequestration of CO₂ in the Texas Gulf Coast region.

Kinetic analysis of reactions involving nitrite and ethanol amine (MEA), piperazine (PZ), diethanol amine (DEA), methylethanol amine (MMEA), and methyldiethanol amine (MDEA) determined the reaction rate of each amine under various conditions. The reactions involving MEA, PZ, DEA, and MMEA were first order in nitrite, carbamate species, and hydronium ion. The tertiary amine, MDEA, did not fit the same rate law. A model accurately predicts reaction kinetics for unhindered primary and secondary amines. The rates of reaction revealed that primary amines react approximately 10 times slower than secondary amines under identical reaction conditions. Increased reactivity was noted in secondary amines which have more electron withdrawing groups attached to the amine. Two proposed mechanisms involve protonation of the carbamate species, nucleophilic attack of carbamic acid by nitrite, and formation of bicarbonate and a nitrosamine. The comparative kinetics can be applied to the analysis of the steady state concentration of nitrosamines in carbon capture, can help identify inhibitors for this reaction, and can be applied to the use of blends to mitigate nitrosation.Item A Trio of New Projects(2015-10-15) Berwald, Juli
