The EU ban on Russian coal imports to take effect from August 2022 will clearly have a major impact on this trade. Australia is the only other major supplier of PCI coal but is unlikely to be able to make up for lost Russian supplies. This is reflected in Australian PCI coal prices which SP recorded as high as US645/tonne in March 2022.

The steel sector is currently the largest industrial consumer of coal, which provides around 75% of its energy demand. Coal is used to generate heat and to make coke, which is instrumental in the chemical reactions necessary to produce steel from iron ore. 2 The iron and steel sector accounts for more emissions than all road freight.

Manufacturing 1 ton of steel needs 50 kg of hydrogen. Replacing coal with hydrogen would raise the total price of a ton of steel by almost onethird. If largescale hydrogen generation reduces the price of H 2 to €/kg by 2030, the price difference between green hydrogen steel and conventional steel would be 10%.

The production of steel during the British Industrial Revolution became cheaper and more reliable thanks to the Bessemer converter, a type of blast furnace that removed undesirable impurities from pig iron. The superior strength and durability of steel over iron meant that the metal took over as the preferred choice of civil engineers to build bridges, tunnels, and railway tracks.
