In recent years, Sargent & Lundy has evaluated many potential sites for new coal-fueled generation. Some of the sites studied were lands adjacent to existing power plants (brownfield sites); others were undeveloped greenfield sites. The numerous technical, environmental, economic, and regulatory issues that bear on power plant siting generally apply to both brownfield and greenfield […]

Most folks probably don’t think that power plants burning coal and ethanol — the latter touted as a having a smaller carbon footprint — have much in common. But at least one ethanol plant — Blue Flint Ethanol in Underwood, N.D. — is co-located with a coal-fired power plant in order to use its excess […]

Carbon dioxide emissions aren’t yet regulated by the EPA, but it’s likely they will be soon. There are many technically feasible, but as-yet-undemonstrated ways to reduce the considerable carbon footprint of any coal-fired plant, whether it uses conventional or unconventional technology. One promising approach to removing CO2 from a plant’s flue gas uses chilled ammonium bicarbonate to drive the separation process.

Chances are good that legislation to “cap and auction” greenhouse gas (GHG) emissions will become law as early as 2009. While many environmentalists, utilities, and energy companies agree that cap and auction is the right framework, huge differences remain. Environmentalists want an 80% reduction of GHG emissions by 2050, or sooner. Energy companies want more […]

Combat veterans use the phrase "fog of war" to explain why carefully prepared battle plans are quickly overwhelmed by chaos once the first bullet is fired. Survivors often describe experiences that are markedly different from those of others standing only yards away. The fog of our industry’s battle to build new generating plants permeates the […]

The FutureGen Industrial Alliance Inc. selected Mattoon, Ill., as the site of the $1.8 billion FutureGen project just before Christmas, but the plant may never move off the drawing board.. FutureGen, the proposed prototype of a near-zero-emissions coal plant, is to demonstrate advanced technologies for coal gasification, electricity production, emissions control, CO 2 capture and […]

Integrated gasification combined-cycle (IGCC) technology, a process of gasifying coal that allows the capture of carbon dioxide emissions, has tremendous potential for meeting future baseload generation demand. Though it is one of the leading alternatives for producing clean power from coal, IGCC faces a precarious future due to rising capital costs and regulatory uncertainty. We’re […]

While noting marginal improvements since last year, America’s power reliability watchdog recently warned that the nation’s growing thirst for electricity will still far exceed planned increases in generation capacity over the next 10 years, and that reserve margins could dip below optimal levels within two or three years in California, the Rocky Mountain states, New […]
