Sample preparation was conducted in accordance with the …
PCI coal for steelmaking soon to be impacted by decarbonisation
Australian PCI coal prices peaked at US$645/ton in March 2022, briefly surpassing that of premium-quality hard coking coal — PCI coal is more usually priced 20%-30% lower. Even after coming off this extreme high, PCI coal was still at a very high US$365/t in early April. Opportunities for hydrogen are apparent short term in blast furnaces
