Coal in the Powder River Basin. The Powder River Basin in the Red Desert stretches for more than 14 million acres from the peaks of Wyoming's Bighorn Mountains to the Yellowstone River in eastern Montana. It provides premier habitat for elk, mule deer, pronghorn antelope, wild turkeys, and the threatened greater sagegrouse in places like Otter ...

The Energy Information Administration estimates (as of October 2022) that in 2021, CO 2 emissions from burning coal for energy accounted for about 20% of total energyrelated CO 2 emissions and for nearly 60% of total CO 2 emissions from the electric power sector. In the past, fly ash was released into the air through the smokestack ...
The Powder River Basin, or PRB, which is home to the largest coal reserves in the United States, currently supplies approximately 40 percent of the nation's coal and accounts for a full 13 ...
Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.
The Powder River Basin (PRB) is a region in southeast Montana and northeast Wyoming about 120 miles east to west and 200 miles north to south known for its coal deposits. It is the single largest source of coal mined in the United States and contains one of the largest deposits of coal in the world. Most of the active coal mining in the Powder River Basin actually takes place in drainages of ...
The objective of this research is to develop a costeffective catalytic pyrolysis process for producing highquality oil and gas from coal with low CO 2 emission. Catalytic pyrolysis of the Powder River Basin coal using composite Na 2 CO 3FeCO 3 catalysts has been investigated in a fixed bed reactor between 500 and 800 °C under atmospheric pressure to evaluate effects of catalyst on quantity ...
Coalfired power plants often utilize a specific coal quality that generators cannot easily replace with coal from other regions. While Powder River Basin coal operators have reported some success in managing costs as production footprints shrink, largescale operations have long been one of the region's primary advantages.
A coal mine in the Powder River Basin has received state recognition for its reclamation efforts. The Wyoming Department of Environmental Quality (DEQ) recognized the Coal Creek Mine with its 2022 Excellence in Mining Reclamation Award for coal. Coal Creek Mine is operated by Thunder Basin Coal Company south of Gillette.
