The True Cost of Coal - groundtruthtrekking

Most coal mining in the U.S. is surface mining, which includes strip mining and mountaintop removal. In surface mines, the original ecosystem at the mine site is destroyed in the process of removing the coal. Coal companies are required to plant vegetation to reclaim the site after mining, restoring the original ecosystem may be difficult, particularly in wetlands areas.

External costs of coal - Global Energy Monitor

In economics, an external cost, or externality, is a negative effect of an economic activity on a third party. When coal is mined and used to generate power, external costs include the impacts of water pollution, toxic coal waste, air pollution, and the long-term damage to ecosystems and human health.

Mountaintop Removal 101 – Appalachian Voices

What is the process of mountaintop removal coal mining? CLEARING. Before mining can begin, all topsoil and vegetation must be removed. Because coal companies frequently are responding to short-term fluctuations in the price of coal, the trees are often not used commercially, but instead are burned or sometimes illegally dumped into valleys.

9.1.1. Carbon Dioxide Capture Approaches netl.doe.gov

Both pre-combustion and oxy-combustion utilize air separation to combust coal in an enriched oxygen environment. However, it is important to note that the amount of oxygen required in oxy-combustion is significantly greater than in pre-combustion applications, increasing CO 2 capture costs. A higher purity oxygen stream would also need to be used.

Coal fired power plant - Energy Education

The conversion of this coal to the end goal of electricity is a multi-faceted process: The coal must be unloaded from the train. Traditional ways of doing this require the use of cranes picking up the coal from the cars, however newer plants have the floor underneath the train tracks drop away, allowing the coal to be dropped into underground containment.

How Coal Works Union of Concerned Scientists

Dec 15, 2017  Since its gasification process allows for the separation and capture of CO2 before combustion, the gas is still in a relatively concentrated and pressurized form. Pulverized coal plants can only capture CO2 after combustion, when it is far more diluted and harder to separate, increasing the costs of implementing CCS.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
