🏭 Calix to build a novel hydrogen-based iron plant using ZESTY tech
💡 What’s ZESTY?
ZESTY = Zero Emissions Steel Technology
⚙️ Uses renewable hydrogen to extract oxygen from iron ore
🌊 Byproduct = Water (No CO₂!)
🏗️ New Demo Plant Goals:
📦 Produce: 30,000 tonnes/year of
– Hydrogen Direct Reduced Iron (H-DRI)
– Hot Briquetted Iron (HBI)
🔥 Energy source = Electric (not fossil-fuel furnace)
⚡ Why It’s Game-Changing:
🧪 Uses 50% less hydrogen than other H-DRI methods
🧲 Works with lower-grade iron ore
♻️ Hydrogen is not burned — reused in the process
🔌 Fully electric = potential for near-zero emissions if powered by renewables
🌍 Big Picture:🏗️ Funding also supports planning for a much larger plant🌱 Adds value to Australia’s #1 export: iron ore🧯 Targets steelmaking — one of the hardest industries to decarbonize
⚠️ Caution:
🟡 Green credentials depend on green hydrogen supply, which remains volatile🟥 BP just exited a major hydrogen project in WA due to fossil fuel strategy shift
🗣️ Calix CEO Phil Hodgson:
“ZESTY could slash hydrogen needs in green steelmaking. That’s a global unlock.”
