It burned North Dakota lignite until about 10 years ago, when it switched to subbituminous coal
from Cloud Peak Energy's Spring Creek mine in Montana.
The plant will use subbituminous coal
imported from Indonesia.
A truly vast (inferred) supply of coal is located in the Northern Alaska-Slope Coal Province-over 120 billion tons of bituminous and subbituminous coal
by one study--so much so that for a developer, given the ton/ year rates, mining all the coal in even one hundred years is unrealistic.
As one of the safest coal producers in the nation, Cloud Peak Energy specializes in the production of low sulfur, subbituminous coal
In contrast to lignite and subbituminous coal
samples, the lowest contents of sulphur species are in bituminous coal.
Environmental Clean Technologies Limited (ECT) is focused on establishing commercial-scale Coldry projects and creating economically valuable and more environmentally responsible Coldry Black Coal Equivalent (BCE) products and water from high-moisture brown coal and subbituminous coal
Our proprietary K-Fuel(TM) process uses heat and pressure to physically and chemically transform high moisture, low-Btu coals, such as subbituminous coal
and lignite, into a more energy efficient, lower-emission fuel.
is used mainly to fuel power plants.
But some utilities that burn subbituminous coal
already have achieved approximately 75 percent reductions using existing control equipment, and a number of new technologies are being developed that can reduce mercury from such coal as effectively as from bituminous coal.
At the same time, production of hard and subbituminous coal
in the western US has increased from 261.
production is subbituminous coal
or lignite and 68% is bituminous coal.
K-Fuel produced by this process from Wyoming's Powder River Basin subbituminous coal
has a heating value at least 60% higher than the raw coal, and, according to KFx literature, produces less than 0.
