Coal

Anyone operating a coal-fired power plant has faced the challenge of keeping coal-handling equipment free of blockages and plugging. Not only do material flow problems interrupt smooth plant operations, but they also require dirty, sometimes dangerous, and often unscheduled maintenance work. As in many other industries, remote-controlled tools can help solve this problem. Bulk material […]

The Tennessee Valley Authority (TVA) will retire more than 3 GW at eight coal units in Alabama and Kentucky to address “challenging trends” that point to lower power demand, a slow economy, uncertainty in commodity pricing, and tougher air pollution rules. The U.S. corporate agency’s board of directors on Nov. 14 approved plans to retire all […]

A communiqué drafted by participants from 22 coal-heavy countries at the Carbon Sequestration Leadership Forum (CSLF) that was held in Washington D.C. last week affirms that carbon capture and storage (CCS) is an indispensable element of any effective response to climate change. Members of the ministerial-level international climate change initiative also urged acceleration of the […]

The Environmental Protection Agency (EPA) exceeded its authority under the federal Clean Air Act when it promulgated the Cross-State Air Pollution Rule (CSAPR) in 2011, nine states argue in a brief filed with the U.S. Supreme Court last week. The brief filed by a bipartisan group of attorneys general from Arizona, Arkansas, Kentucky, Missouri, Montana, […]

By 2035, renewables will hold a 30% share of the global power mix but just 1% of the world’s fossil fuel–fired power plants will be equipped with carbon capture and storage (CCS), reports the International Energy Agency (IEA) in its newly released World Energy Outlook (WEO-2013). The annual report presents a central scenario in which global […]

In international trade, a gap between theory and practice has always existed. Theory stresses, as an underlying ideal, the economic benefits of trade based on comparative advantage. In practice, and for a variety of reasons—institutional constraints, political factors, ambiguity of legal doctrine, bilateral or multilateral treaty obligations—the ideal intermittently bows to reality, whether in the […]

Eighteen carbon capture projects across the U.S. have been chosen to receive $84 million in federal funding to help improve the efficiency and drive down costs of carbon capture processes for new and existing coal power plants. The Department of Energy (DOE), which announced selection of the projects today, said funded research will focus on […]

Duke Energy’s drive to reorient its fleet away from coal took another step on Nov. 4 when it announced demolition plans for its 84-year-old Riverbend Steam Station in Gaston County, N.C. The 454-MW plant was one of Duke’s oldest fossil assets, having come online in 1929. It was retired in April, two years ahead of […]

An executive order signed by President Obama today requires federal agencies to promote the “dual goals” of a greater resilience to climate change and a removal of barriers to carbon-curbing measures, including carbon sequestration. Climate change impacts that include “prolonged periods of excessively high temperatures, more heavy downpours, an increase in wildfires, more severe droughts, permafrost thawing, […]

The total costs of Mississippi Power’s Kemper County integrated gasification combined cycle (IGCC) plant—the nation’s only large-scale integrated carbon capture and sequestration project (CCS) under construction—have now almost doubled to $4.02 billion. A review of the Kemper facility’s construction schedule and costs completed this month by Mississippi Power management prompted the company to push back […]
