Coalless steel

Over on ABC's Unleashed there is a article called 'A renewable reality: don't let politics get in the way'.

In it I got onto the energy needed to make steel. I said steel could be made and was challenged on that point. I knew that steel had been made with charcoal pre early 18th century. What I didn't realise is that do to its total lack of coal, Sweden currently has at least some charcoal based production! ;)
