Greener Nickel Extraction: A Step Towards Sustainable EV Future

ree

In a major breakthrough, scientists have developed a new energy-efficient method to extract nickel, which reduces direct CO₂ emissions by up to 84% compared to traditional processes. This innovation could reshape the future of green technologies, especially electric mobility.


Why is Nickel Important?

  • Atomic Number: 28

  • Type: Lustrous, silvery-white, hard, and ductile metal

  • Magnetic: Can be magnetised

  • Dual Nature: Exhibits both ferrous and non-ferrous characteristics


Key Applications

  • Corrosion resistance: Used to plate other metals

  • Rechargeable batteries: Especially in Electric Vehicles (EVs)

  • Aerospace alloys, coins, and electronics


Major Minerals

  • Pentlandite (main commercial source)

  • Garnierite

  • Nickeliferous Limonite

📘 Prelims Practice Question (UPSC CSE Type):

Q. Consider the following statements about Nickel:

  1. It is a non-magnetic metal used in EV batteries.

  2. Nickel can be obtained from garnierite and pentlandite minerals.

  3. It exhibits both ferrous and non-ferrous properties.

Which of the statements given above is/are correct?

A. 2 and 3 only

B. 1 and 2 only

C. 1 and 3 only

D. 1, 2 and 3


Answer: A. 2 and 3 only

Explanation:

  • Statement 1 is incorrect: Nickel is magnetic, not non-magnetic.

  • Statements 2 and 3 are correct: Garnierite and pentlandite are primary sources, and it shows both ferrous and non-ferrous traits.


✍️ Mains Practice Question (GS Paper 3):

Discuss the strategic importance of Nickel in the transition towards clean energy. How can recent innovations in extraction technology contribute to India’s climate goals and energy security?
