Capture Capacity

Existing centralised databases of industrial-scale CCS report various characteristics including capture capacities but do not specify the amount of CO2 stored from commercial CCS facilities. We review a variety of publicly available sources to estimate the amount of CO2 that has been captured and stored by operational CCS facilities since 1996. We organise these sources into three categories broadly corresponding to the associated degree of legal liability or auditing. Data were found for twenty commercial-scale facilities, indicating a combined capture capacity of 36 MtCO2 per year. Combining data from all three categories suggests that approximately 27 MtCO2 of this was stored in the subsurface in 2019. However, considering only categories 2 and 1 of reporting, storage estimates for 2019 reduce to 25 MtCO2 and 11 MtCO2, respectively. Nearly half of the projects investigated here are reporting injection rates close to their originally proposed capture rate capacity. Our data also show that between 1996 and 2020, 196 Mt of CO2 has been cumulatively stored, combining data for all three categories. The database presented here provides further insight into the factors influencing performances of CCS operations and the data can be used to parameterise energy system models for analysing plausible scaleup trajectories of CCS.

In recent years horticulture programs at universities across the United States have experienced a decline in student numbers. Researchers at the Univ. of Florida and Texas A&M Univ. have developed a survey to gain insight into the influences on undergraduate students who major in horticulture. Five universities participated in the survey of undergraduate horticulture programs, these include the Univ. of Florida, Texas A&M Univ., Oklahoma State Univ., Univ. of Tennessee, and Kansas State Univ. Approximately 600 surveys were sent to the schools during the 1997 fall semester. The questionnaires were completed by horticulture majors and nonmajors taking classes in the horticulture departments. The survey consisted of two main sections. The first section examined student demographic information, high school history, university history and horticulture background and was completed by all students. Only horticulture majors completed the second section, which examined factors influencing choice of horticulture as a major. Results examine fundamental predictors in promoting student interest in horticulture, demographic variables that may influence student choice of major, and student satisfaction and attitude toward current collegiate horticulture programs. Findings from this study will provide insight into the status of post-secondary horticulture education and assist in identifying methods to increase student enrollment in horticulture programs across the country.

And Storage

Carbon capture and storage (CCS) has been increasingly looking like a promising strategy to reduce CO2 emissions and meet the Paris agreement’s climate target. To ensure that CCS is safe and successful, an efficient monitoring program that will prevent storage reservoir leakage and drinking water contamination in groundwater aquifers must be implemented. However, geologic CO2 sequestration (GCS) sites are not completely certain about the geological properties, which makes it difficult to predict the behavior of the injected gases, CO2 brine leakage rates through wellbores, and CO2 plume migration. Significant effort is required to observe how CO2 behaves in reservoirs. A key question is: Will the CO2 injection and storage behave as expected, and can we anticipate leakages? History matching of reservoir models can mitigate uncertainty towards a predictive strategy. It could prove challenging to develop a set of history matching models that preserve geological realism. A new Bayesian evidential learning (BEL) protocol for uncertainty quantification was released through literature, as an alternative to the model-space inversion in the history-matching approach. Consequently, an ensemble of previous geological models was developed using a prior distribution’s Monte Carlo simulation, followed by direct forecasting (DF) for joint uncertainty quantification. The goal of this work is to use prior models to identify a statistical relationship between data prediction, ensemble models, and data variables, without any explicit model inversion. The paper also introduces a new DF implementation using an ensemble smoother and shows that the new implementation can make the computation more robust than the standard method. The Utsira saline aquifer west of Norway is used to exemplify BEL’s ability to predict the CO2 mass and leakages and improve decision support regarding CO2 storage projects.

Capture Techniques

Carbon capture and storage (CCS) is increasingly considered to be a tool that can significantly reduce the emission of CO2. It is viewed as a technology that can contribute to a substantial, global reduction of emitted CO2 within the timeframe that seems available for mitigating the effects of present and continued emission. In order to develop the CCS method the European Union (EU) has supported research programmes for more than a decade, which focus on capture techniques, transport and geological storage. The results of the numerous research projects on geological storage are summarised in a comprehensive best practice manual outlining guidelines for storage in saline aquifers (Chadwick et al. 2008). A detailed directive for geological storage is under implementation (European Commission 2009), and the EU has furthermore established a programme for supporting the development of more than ten large-scale demonstration plants throughout Europe. Geological investigations show that suitable storage sites are present in most European countries. In Denmark initial investigations conducted by the Geological Survey of Denmark and Greenland and private companies indicate that there is significant storage potential at several locations in the subsurface.

Structured Literature Review

This chapter provides an insight into why Green Marketing (GM) and Sustainable Consumption (SC) of green products are subject of research and discussion in contemporary society. It analyzed the extent of GM in developing countries using cases of Nigeria and Kenya, factors influencing GM, the benefits of GM on the environment and firms, and the challenges. The study is both exploratory with the use of structured literature review of publications in peer reviewed academic journals on GM and SC, and empirical in nature. The findings on respondents rating of factors influencing green purchase behavior showed that concern for health and environment was considered as the most important in Nigeria, while in Kenya it was social awareness and value. For an effective GM and SC, government at all levels has a role of creating awareness to boost green knowledge through educative campaign programs and enforcing green agenda. Government can make regulations relating to GM and ensure SC by lowering the cost when compared to the conventional marketing

The idea of bridging literacies has been a topic of much research and theory, and educators continue to struggle to help students understand how their learning transcends the classroom walls. Contributing to the discussion, this chapter focuses on factors influencing video game learning, examining the decisions and game play of eight academically struggling eleventh-grade males. Data from two related qualitative studies suggest that direct and peripheral factors influenced students’ game play. Findings from these two studies are important to the discussion of educational gaming because they can inform educators of students’ struggles and successes in learning outside the classroom. Overall, the evaluation of students’ video gaming can provide educators insight into the affordances of this digital literacy and issues affecting student learning outside the classroom.
