Swedish green steel venture HYBRIT said on Wednesday that it had made the world’s first customer delivery of steel produced without using coal as it looks to revolutionize an industry that accounts for around 8% of global greenhouse gas emissions.

HYBRIT, owned by SSAB (SSABa.ST), state-owned utility Vattenfall (VATN.UL) and miner LKAB, said it would deliver the steel to truck-maker Volvo AB (VOLVb.ST) as a trial run before full commercial production in 2026.
