An assessment of geologic sequestration potential in the panhandle of Florida USA

One alternative to reduce global greenhouse gas emissions is to store the emissions in underground geologic sequestration repositories. The efficacy of this approach has been favorably evaluated by numerous authors over the last 15 years. This paper discusses an assessment of the overall feasibility of storing emissions in three different repositories in the Florida panhandle located in the Southeastern United States. The feasibility assessment evaluates both saline aquifers and oil reservoirs located in the panhandle region. The overall feasibility is driven by the available geologic sequestration capacity, the transportation cost to deliver emissions to a respective repository, and other engineering and regulatory issues. The geologic sequestration capacity is generally controlled by the so-called storage efficiency, a variable dependent on the site-specific geology, reservoir conditions, and the injected fluid characteristics. For this paper, storage efficiency for saline repositories was assessed in more detail using numerical modeling. Based on the work completed, the 3 repositories studied have at least 4.55 gigatonnes of capacity to sequester CO2

Techno-economic analysis and optimization models for carbon capture and storage: a survey

Carbon dioxide (CO2) emissions are projected to increase significantly during the coming decades if effective environmental policies are not implemented, and the negative impacts of carbon emissions will eventually hinder economic and human development. Carbon capture and storage is proposed to mitigate the global climate change due to the increased concentration of carbon dioxide in the atmosphere. In this article, we focus on the technical developments and economic analysis of carbon capture and storage using optimization models and algorithms. The three main components of carbon capture and storage we discuss are: carbon capture, carbon dioxide transportation and carbon sequestration. In addition, to fulfill carbon dioxide reduction requirements, we also discuss the use ofmathematical programming models solving energy expansion planning, CO2 network design problems and CO 2 storage problems. Through the combination of technical and economic analysis of carbon capture and storage technologies, possible directions for sustainable developments of low-carbon energy economy can be evaluated. © Springer-Verlag Berlin Heidelberg 2013
