Steel products are widely used in the construction industry and for the development of infrastructure projects, because they are versatile, durable, and affordable. Energy demand and ‘greenhouse gas’ (GHG) emissions associated with the United Kingdom (UK) Iron and (ii) compare and contrast different options for making UK steel production more environmentally benign, particularly in regard to its decarbonisation. Some key ‘deep decarbonisation’, or ‘disruptive’, options for producing green steel in the UK are evaluated drawing on the experience from other nation-states and regions. These include the prospects for carbon capture and storage (CCS), the use of bioenergy resources, hydrogen-based production, electrification, and the least desirable option of deindustrialisation (i.e., reducing or out-sourcing of UK steel production ‘offshore’). ‘Circular economy’ interventions or resource efficiency improvements (‘reduce, reuse, recycle’) are also discussed. The potential reductions in GHG emissions from the UK Iron & Steel sector overall out to 2050 are then illustrated by comparison with previous technology roadmaps or transition pathways. The lessons learned are applicable across much of the industrialised world.
