Bit of a mixed (one might say hazy) read through for hazer shareholders on the Santos announcement it will supply gas to whyalla from 2030.
In the announcement they mention green iron, which in the same breath as gas is very promising for hazer, but then they talk about gas being lower emission than coal in a blast furnace, less promising.
Given the timing (supply from 2030), there is probably plenty of time to convert a furnace to run on hydrogen if M and Hazer win the bid.
