Uncertainty about CO₂ emissions legislation is prompting power plant owners to consider the possibility of accommodating "add-on" CO₂ capture and sequestration solutions for coal-fired plants in the future. Those same plant owners may be overlooking the possibility that future natural gas – fired combined cycles will also be subject to CO₂ capture requirements. This month we examine the capture options. In a future issue, Part II will present the installation and operating costs of different carbon capture technologies.

Carbon capture and storage (CCS) has of late gained steam as the best way to mitigate emissions of the greenhouse gas carbon dioxide (CO2) from fossil fuel power plants, despite evidence that the approach would require much energy and increase the fuel needs of a coal-fired plant by more than 25%. A new study from […]

The New Source Review (NSR) permitting program was originally created as part of the 1977 Clean Air Act Amendments to ensure that new power generation facilities were properly outfitted with all the necessary air quality control systems when constructed. Plants in operation were exempt until they made plant modifications viewed as beyond “routine maintenance,” a term whose definition has been a moving target. Is it time for the NSR to take a back seat to improved plant efficiency and reduced carbon emissions?

Reducing dust from coal conveyors has moved from a housekeeping chore to a safety challenge, especially with Powder River Basin coals. Here’s what you need to know about the latest coal-handling system design.

The EPA has identified 44 "high hazard" coal ash ponds around the U.S., and a recent Tennessee Valley Authority report indicates that the agency should have known its Kingston Plant pond would have been one of them.

An analysis by the Center on Budget and Policy Priorities concluded that two-thirds of the value of carbon emission allowances described by the recent H.R. 2545 will benefit utility business customers and households in the top quartile of personal income. The middle quintile will see increased cost for electricity.

MIT researchers push for faster commercialization of carbon capture technologies for coal-fired power plants by reducing system costs.

The annual meeting of the Powder River Basin Coal Users’ Group was held in association with the ELECTRIC POWER conference in early May in Chicago. Get a taste of the festivities, technical meetings, and the announcement of the group’s 2009 Large and Small Plant of the Year winners in this conference report.

Energy provider ScottishPower on May 29 flicked on the switch of a carbon capture and storage (CCS) pilot program at its 2,304-MW coal-fired Longannet power plant, in Fife, Scotland, marking the beginning of a seven-month test — and the first time a UK coal-fired power plant has reportedly attempted to capture its carbon emissions.

City Water, Light & Power (CWLP), the municipal utilities agency of the City of Springfield, Ill., determined that coal-fired generation was its best alternative for providing long-term reliable and economic electricity to the city’s residents. For negotiating an unprecedented agreement with the Sierra Club that allowed the project to move forward, for choosing the latest in coal-fired technology and air quality control systems as the foundation for the city’s comprehensive energy policy, and for assembling a tightly integrated team that completed the project well before the contractual deadline and under budget, CWLP’s Dallman 4 is awarded POWER magazine’s 2009 Plant of the Year award.
