Key to the manufacture of everything from wind turbines to electric vehicles, steel is a critical building block of the green revolution. However, its starring role in our low carbon future is somewhat undermined by the fact that the processes used to produce it account for a large chunk - around seven per cent - of global CO2 emissions.
