Making steel without coal: Lets talk about coal

This has a much higher energy value than coal, and is better geared to producing high temperatures for smelting. Coke came into use in Great Britain in the 1700s, partly because of its superior crushing strength to that of coal. Blast furnaces for making iron and steel could be built taller and bigger, to improve economies of scale.
