Nickel and Its Usage: Recently, a study by the Max Planck Institute for Sustainable Materials introduced a hydrogen plasma-based technique for nickel extraction, presenting a more sustainable alternative to traditional, carbon-intensive methods.
o The resulting hydrogen plasma then reacts with nickel oxide to produce pure nickel and water—eliminating carbon dioxide emissions typically generated by conventional extraction processes.
o Key benefits : Up to 84% reduction in direct CO₂ emissions
ü 18% more energy-efficient than traditional multistep methods
ü Yields high-purity ferronickel suitable for stainless steel without extensive refining
o Source and Occurrence: Never found in pure form naturally; extracted from sulfide and laterite ores, often alongside copper and uranium.
o Applications : Stainless steel production (65% of global demand) for added strength, corrosion resistance, and durability.
ü Construction, kitchenware, medical instruments, and infrastructure projects.
ü Aerospace and defence due to its heat resistance (jet engines, turbines, and superalloys)
ü Green technologies such as solar panels, wind turbines, and battery storage systems supporting net-zero targets.
