Atmospheric levels of carbon dioxide (CO2) have increased from a pre-industrial level of 280 parts-per-million (ppm) to today's level of 379 ppm [Reference 2]. The primary source of anthropogenic CO2 is combustion of fossil fuels. Studies have shown that capture of anthropogenic CO2 and carbon sequestration could help to stabilize the concentration of atmospheric CO2. This paper investigates the leading methods for carbon sequestration and evaluates them on the bases of cost, capacity and environmental consequences. Other factors such as geographical constraints and the current state of technology are also considered. This white paper covers the following post-capture aspects of carbon sequestration: compression, transport, storage, and monitoring, mitigation and verification (MM+V).
Energy White Paper: Considerations for Low Sulfur Coal Blending at B. L. England Station

This paper describes the factors that control the implementation of an on-site coal blending facility at the B. L. England Station. The features of the existing coal stockpile and handling system arrangement that impact the blending alternatives are also discussed. The paper details the evaluations performed to compare the blending control options, including coal storage, online fuel analysis and mass-based blending. In addition, the approach used to incorporate the existing equipment and control system at B. L. England Station to reliably produce a consistent, controlled coal blend is described. Finally, the paper provides a comparison of the estimated costs and schedules required to implement the on-site coal blending alternatives.
Energy White Paper: Technical Overview of Carbon Dioxide Capture Technologies for Coal-Fired Power Plants

Concerns about global climate change have prompted interest in capturing and sequestering CO2 generated at coal-fired power plants. This document provides a technical introduction to methods of capturing CO2, which involves separating the CO2 from the other constituents in the flue gas. The methods discussed in this paper are post-combustion capture, oxygen-fired combustion, and pre-combustion capture.

This overview examines the different technologies available for reducing NOX emissions from combustion furnaces. For each of the general types of NOX emission controls (combustion control and post-combustion control), the characteristics of the individual technologies are identified, including a description of the features impacting their selection and implementation. A range of the level of NOX emissions control provided and the capital costs associated with implementing each individual technology are presented.
