DOE to Design and Build Advanced Gas Cleanup System for IGCC Plants
The U.S. Department of Energy (DOE) is preparing to conduct what it says is the world’s first large-scale project to design, build, and test a warm gas cleanup system to remove multiple contaminants from coal-derived syngas. The federal agency has teamed with Research Triangle Institute (RTI) International, a scientific research firm, to demonstrate the 50-MW system at Tampa Electric Co.’s 250-MW integrated gasification combined-cycle (IGCC) power plant.

Federal Court Overturns Bush-Era Ozone Rule as EPA Races to Replace CAIR and CAMR
A federal appeals court last week struck down parts of a 2005 Environmental Protection Agency (EPA) rule governing power plant and factory pollution in areas where levels exceeded the federal 8-hour ozone standard. Also last week, an agency official told a Senate panel that the EPA was quickly moving forward to replace the Clean Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR).

"Business as Usual" Could Force UK to Rely Heavily on Gas Generation
UK business group CBI on Monday released a report warning that the country’s current policy of incentivizing investments in wind power would result in too little investment in other forms of low-carbon energy, such as nuclear and clean coal. The approach will make energy security harder to achieve, and it could jeopardize the UK’s ability to meet climate change targets, the group said.

Climate bill faces uncertain future in Senate
By Kennedy Maize The slim passage in late June of the House Democrats’ global warming bill – 219-212 – reminds old-timers of the Clinton administration’s passage of a Btu tax in 1993 by a 219-213 vote in the House, only to see it crater in the Senate. Is the same result likely for the Obama […]

Digital Networks Prove Reliable, Reduce Costs
The debate over the benefits of using digital bus networks as the communications backbone of new power plants is all but settled. The technology is maturing, and the reliability of digital hardware is superior to that of hardwired systems. Newmont Gold Mining’s 200-MW TS Power Plant is perhaps the power industry’s best example of how a plantwide digital controls architecture can provide exceptional reliability and be significantly less costly to install.

Ark. Appeals Court Blocks Turk Plant; SWEPCO Files Appeal, Will Continue Construction
An Arkansas appeals court last week overturned on technical grounds a key decision by the state regulators that authorized construction of Southwestern Electric Power Co.’s (SWEPCO’s) 600-MW John W. Turk Jr. coal-fired power plant in Hempstead County—the nation’s first ultrasupercritical project. SWEPCO on Monday filed an appeal with the Arkansas Supreme Court and said it would continue the plant’s construction because delays could prove costly.

Designing an Ultrasupercritical Steam Turbine
Carbon emissions produced by the combustion of coal may be collected and stored in the future, but a better approach (in the near term at least) is to reduce the carbon produced through efficient combustion technologies. Increasing the efficiency of new plants using ultrasupercritical technology will net less carbon released per megawatt-hour using the world’s abundant coal reserves while producing electricity at the lowest possible cost.

Report: Combination of “Rarely Found” Factors Led to TVA Coal Ash Spill
The breach of a 50-year-old coal ash storage pond and subsequent ash spill at the Tennessee Valley Authority’s (TVA’s) Kingston Fossil Plant in Roane County, Tenn., last December was caused by a rare and complex combination of conditions, a six-month independent engineering study has found. These included the existence of an unusual bottom layer of ash and silt, the high water content of the wet ash, the increasing height of ash, and the construction of sloping dikes over the wet ash.
