Insulation and lagging are key to saving energy in a typical steam plant, and plant operators would be well advised to pay close attention to energy losses in their insulation and lagging systems.

Supporters of a new carbon tax are using arguments aimed at conservatives (it can be revenue neutral) and liberals (it can help the environment) alike. The damage to the U.S. economy, manufacturing competitiveness, and society’s poorest citizens outweighs the government’s need for a new revenue stream.

Expect the EPA to increase the use NEPA data requests, ostensibly related to climate change analysis, as an excuse to slow or stymie new energy system development.

The world’s first supercritical pulverized coal–fired low mass flux vertical tube Benson boiler is Jinzhushan 3, located in Hunan Province of the People’s Republic of China. The 600-MW Babcock & Wilcox Power Generation Group Inc. once-through boiler burns Chinese anthracite using downshot pulverized coal (PC) technology. Part 2 of this three-part article discusses the boiler technology. The third and final part will review the plant’s performance test results.

Despite growing concern about cybersecurity both in and outside of Washington, the Senate’s cybersecurity bill died a second time on Nov. 13. The apparent inability of Congress to pass legislation designed to protect critical U.S. infrastructure could lead to President Barack Obama implementing some of the bill’s provisions via executive order. A day after the bill failed to gain 60 votes for passage, a recently declassified report was released that finds the U.S. power grid is vulnerable to attacks that could be more destructive than natural disasters such as Hurricane Sandy.

In a project funded by the U.S. Department of Energy’s (DOE’s) Office of Fossil Energy (OFE), researchers at The Ohio State University have developed what they call a groundbreaking new hybrid membrane that combines the separation performance of inorganic membranes with the cost-effectiveness of polymer membranes. The breakthrough technology has vast commercial potential for use at coal-fired power plants with carbon capture, utilization, and storage (CCUS), a key element in national efforts to mitigate climate change.

On Monday, as First Wind announced its 69-MW Kawailoa Wind Project had gone into commercial operations on Oahu, other news underscored the difficulty the island state faces in trying to substitute renewables for expensive, imported fossil fuels.

A reconsidered proposal issued by the U.S. Environmental Protection Agency (EPA) on Friday sets out slightly weakened emission limits for mercury, particulate matter (PM), acid gases, and certain individual metals for future coal- and oil-fired power plants.

A decision by the Environmental Protection Agency (EPA) to impose new pollution limits on three coal-fired power plants in Arizona on Friday drew criticism from state officials, who said that the costly measure, which overrides the state’s regional haze plan, is designed to protect visibility, not public health.
