This report shares initial lessons learned about procuring biochar in Australia.
Lesson learnt No.1: Limited supply of biochar for pilot and plant trials
Objective: Biochar from renewable sources has the potential to replace some of the coal used within an integrated steelworks and thus reduce Green House Gases (GHG) emissions. With the support of ARENA, BlueScope is looking to conduct trials to assess the risks of the pneumatic conveyance of biochar, mixed with pulverised coal, for injection into the blast furnace. Pilot trials are to be conducted at the Bulk Materials Engineering Australia’s test facility at the University of Wollongong. Following the pilot testing, plant trials are to be conducted at the Port Kembla Steelworks (PSKW), where different ratios of biochar will be mixed with pulverised coal, pneumatically conveyed to No.5 Blast Furnace, and injected through the tuyeres. This lesson is about the supply of biochar for the trials.
