Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years agoWhat are the types of coal 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 carbon rich and harder material aka brown coal is the lowest grade coal with the least concentration of

How do we make hydrogen from coal and is it really a You can think of coal s formation process as a progression from biomass Brown coal thus contains slightly more hydrogen than black coal Coal Coal one of the most important primary fossil fuels a solid carbon rich material usually brown or black that most often occurs in stratified sedimentary deposits which may later be subjected to high temperatures and pressures during mountain building resulting in
