Techno‐Economic Analysis of Methane Pyrolysis in Molten Metals: Decarbonizing Natural Gas

“…The cost of the electric arc heater was estimated using the International Energy Agency's quoted $80 t −1 y −1 EAF Investment costs, a figure which agrees with Bosley et al. ), the 427‐t inventory of iron and a 1‐h turnaround period (or tap‐to‐tap time) for an arc furnace of this size , .…”

“…The PSA unit required for product separation and recycling has been costed by scaling the throughput capacity from an SMR facility. The cost of the electric arc heater was estimated using the International Energy Agency's [40] quoted $80 t -1 y -1 EAF Investment costs, a figure which agrees with Bosley et al [41]), the 427-t inventory of iron and a 1-h turnaround period (or tap-to-tap time) for an arc furnace of this size [42,43].…”
