The promise of shale gas has been dominating the energy debate for several years now.

Utilities have until April 2015 to comply with the Mercury and Air Toxics Standard, otherwise known as MATS.

The outlook for coal-fired power production in the U.S. is not as ominous as most people think.

With a slew of rules from the U.S. Environmental Protection Agency in effect, under review or being rewritten, power producers are looking for ways to reduce emissions of mercury and other pollutants, either by installing emissions controls, switching to low-sulfur coal or converting coal-fired equipment to burn natural gas.

Things change fast in air dispersion modeling. Immediate effects occur from tightened standards, shorter averaging times and new pollutants.

Pulling the trigger is hard to do without a target.

ABB Low Voltage Products division has released the TVOC-2, a new generation of its proprietary Arc Guard System designed to protect electrical equipment from arc flashes.

In coal-fired power plants, measurement and control of pH is critical to the efficient operation of wet flue gas scrubbers.

If you relied solely on EPA's press releases to understand the impacts of new regulations and revised National Ambient Air Quality Standards (NAAQS), you would view the environment as yes or no, good or bad, black or white.

Utilities with coal-fired power plants will soon have to comply with the new Mercury and Air Toxics Standards (MATS) regulation, which focuses on mercury and other hazardous pollutants.

One of the first steps in permitting any project is to calculate the potential-to-emit (PTE).

Entergy Corp. (NYSE: ETR) appointed Jeff S. Forbes  as executive vice president, nuclear operations and chief nuclear officer at Entergy Nuclear effective Jan 2.Forbes will be replacing John Herron, who has spent 33 years in the nuclear industry and announced his retirement effective March 31.

Novinda Corp., located at booth No. 3965, announced that its Amended Silicates, a reagent for the removal of mercury emissions from coal-fired power plants, was named a 2012 Product of the Year.

The pursuit of non-conventional sources of oil and gas requires that valves, bearings and other components be able to withstand the highly abrasive materials they process.

About 50 miles northeast of Louisville, Ky., in a rural district on about 2,200 acres along the banks of the Ohio River is the Trimble County power station.

Coal power generation in the U.S. stands at a crossroads. Abundant low-cost natural gas, federal environmental requirements and uncertainty over future regulation of greenhouse gas (GHG) emissions are driving the closure of older, less-efficient coal units and cancellation of planned investments in new coal generation capacity.

The Cross-State Air Pollution Rule (CSAPR) was stayed in December 2011 and vacated on Aug. 21, 2012.

Quiet excitement marked the morning of Aug. 20, 2012, for the geologists and engineers of the Southeast Regional Carbon Sequestration Partnership (SECARB) as carbon dioxide (CO₂) from a coal-fired power plant began flowing through a newly constructed pipeline, down an injection well and into the Paluxy Formation — 9,400 feet below ground surface.

In response to a court order under the Clean Air Act, in June the U.S. Environmental Protection Agency (EPA) proposed updates to its national air quality standards for fine particle pollution, including soot (known as PM2.5).
