At an Alumni Back to Campus event, NIT Srinagar hosted Dr. Ubaid Manzoor from the Max Planck Institute for Sustainable Materials. His talk focused on why the green energy transition depends on metals like nickel, copper and cobalt, and why conventional metal production is a major source of emissions. One tonne of nickel can generate roughly 22 to 28 tonnes of CO2. Manzoor discussed hydrogen plasma smelting reduction, or HPSR, a process that uses electricity and reactive hydrogen to extract metals from low-grade nickel laterites and deep-sea polymetallic nodules. He argued that cleaner metallurgy needs more than swapping carbon for hydrogen, it requires redesigning the production system itself. The event connects academic research with the practical challenge of decarbonizing materials supply. For anyone tracking low-carbon industry or critical minerals, the talk highlights where the next bottlenecks may appear.

NIT Srinagar brought an alumnus from the Max Planck Institute to talk about metals and the energy transition. The key stat: one tonne of nickel can mean 22 to 28 tonnes of CO2. That is the part most people miss. Worth a read if you track hard-to-abate sectors.

HPSR sounds promising, but the article does not say what powers the electric process. If the electricity or hydrogen comes from fossil sources, the CO2 per tonne may not drop much. Any word on pilot scale or energy input per tonne of metal?

Good framing that the green transition is a metals transition. But without a price on emissions, low-carbon metallurgy stays a research project. Hydrogen plasma reduction needs to compete with conventional smelting on cost, and policy is what closes that gap.

Replacing carbon with hydrogen is not enough. The interesting part is combining reduction, melting and separation into one electric process. That cuts energy steps, but the economics depend on hydrogen cost and ore grade. Low-grade laterites are a tough case.

Deep-sea polymetallic nodules are a tricky feedstock. The metallurgy may be cleaner, but mining the seabed has its own environmental questions. The article does not touch that tradeoff. Still useful background for anyone following critical minerals supply.
