Electrolysis is a process that splits hydrogen from water using an electric current. Electrolysis is commonly used in high school science classes to demonstrate chemical reactions and hydrogen production. On a large, commercial scale, the process may be referred to as powertogas, where power is electricity and hydrogen is gas. Electrolysis ...

The process of generating electricity from coal is one of the oldest methods of electricity production. Firstly, coal is mined from the ground, and transported to the power plant. In most circumstances it is finely ground, turning it into powder that burns better, and then burned in a furnace. The heat from the furnace heats water, generating ...

Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal's ...

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.
