    Great SCO2T! Rapid tool for carbon sequestration science, engineering, and economics

    Full text link
    CO2 capture and storage (CCS) technology is likely to be widely deployed in coming decades in response to major climate and economics drivers: CCS is part of every clean energy pathway that limits global warming to 2C or less and receives significant CO2 tax credits in the United States. These drivers are likely to stimulate capture, transport, and storage of hundreds of millions or billions of tonnes of CO2 annually. A key part of the CCS puzzle will be identifying and characterizing suitable storage sites for vast amounts of CO2. We introduce a new software tool called SCO2T (Sequestration of CO2 Tool, pronounced "Scott") to rapidly characterizing saline storage reservoirs. The tool is designed to rapidly screen hundreds of thousands of reservoirs, perform sensitivity and uncertainty analyses, and link sequestration engineering (injection rates, reservoir capacities, plume dimensions) to sequestration economics (costs constructed from around 70 separate economic inputs). We describe the novel science developments supporting SCO2T including a new approach to estimating CO2 injection rates and CO2 plume dimensions as well as key advances linking sequestration engineering with economics. Next, we perform a sensitivity and uncertainty analysis of geology combinations (including formation depth, thickness, permeability, porosity, and temperature) to understand the impact on carbon sequestration. Through the sensitivity analysis we show that increasing depth and permeability both can lead to increased CO2 injection rates, increased storage potential, and reduced costs, while increasing porosity reduces costs without impacting the injection rate (CO2 is injected at a constant pressure in all cases) by increasing the reservoir capacity.Comment: CO2 capture and storage; carbon sequestration; reduced-order modeling; climate change; economic

    ""To Make a Pure Resort"": The Conflict Between Temperance and Profit at the Saltair Resort Under the Church of Jesus Christ of Latter-Day Saints

    No full text
    In 1893 Saltair, a resort with a massive Moorish revival pavilion, was built on the shores of the Great Salt Lake and attracted visitors from across the state of Utah. Owned by the Church of Jesus Christ of Latter-Day Saints, which was heavily influenced by the temperance movement, the question of whether alcohol should be served was a controversial subject by the owners and visitors alike. The Church wanted a wholesome resort where families could relax in peace away from alcoholic influences yet were also concerned that banning alcohol would result in the loss of prots. Despite this controversy and the hesitancy of the Mormon owners to sell alcohol, evidence of alcohol consumption is prevalent in the archaeological record. Here, I examine the role of alcohol at Saltair, and the spaces in which it was consumed. Additionally, I consider the attitudes that patrons and owners of Saltair had towards alcohol, and how its presence impacted their experience at the resort.masters, M.A., Anthropology -- University of Idaho - College of Graduate Studies, 2020-0

    The Common Core State Standards Initiative and the Achievement Gap

    The purpose of this study was to (a) examine the Common Core State Standards Initiative (CCSSI) to (b) explore differences in student achievement according to when groups of states adopted and fully implemented the CCSSI (i.e., early adopter states, late adopter states, non-adopter states, and withdrawn adopter states).and (c) investigate effect of CCSSI on the achievement gap. The population for this study was the U.S. fifty states and District of Columbia Both 2009 and 2016 archival American College Test (ACT) mean composite scores were utilized. The year 2009 served as baseline data, because states adopted and began implementing at that time; 2016 was used for data collection and analysis, because states that had chosen to adopt, implement, or withdraw had stabilized. Descriptive statistics were run and displayed in tables. Inferential statistics included: (a) paired samples t-tests—to determine whether there was a statistically significant difference among the race groups from 2009 to 2016; (b) independent samples t-tests—to detect significant differences in ACT means; and, (c) two-way between groups analysis of variance (ANOVA)—to explore the impact of state adoption group by race as measured by the 2016 ACT mean composite score. Among the major findings: (a) no statistically significant difference in ACT scores from 2009 to 2016 was found for any of the four groups of states; (b) In both 2009 and 2016, blacks had the lowest mean composite scores, and (c) in both 2009 and 2016, the non-adopter states decreased in mean composite scores overall and in each racial demographic
