The coal mining process releases methane, which is 87 more potent as a greenhouse gas than CO2 over a 20 year period (4). Carbon capture and storage (CCS) technologies have been marketed as a way to address climate emissions from burning coal, by pumping CO2 produced through burning coal underground isntead of into the air.

Jun 22, 2016 · It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal. By 1920, nearly 90% of US steel was produced using coke.
