Critical Minerals important for India’s growth (GS Paper I – Geography, GS Paper III – Economy)

Introduction (Context)

The 21st century is witnessing a fundamental shift in global resource geopolitics from fossil fuels to critical minerals. As the world moves toward a cleaner, digital, and technologically advanced future, the demand for minerals like lithium, cobalt, nickel, and rare earth elements has surged. Hence, India must explore within as iIt is near-impossible to secure mineral supply chains from overseas. 

What are Critical Minerals?

Usage of Critical Minerals

Critical minerals are essential components of various clean energy technologies and industries. Their importance can be highlighted across different sectors:

  1. Solar energy
  1. Wind energy
  1. Electric vehicles (EVs)
  1. Energy storage

Global Status of Critical Mineral Supply Chains

Processing Monopoly:

Status of Critical Minerals in India

Critical Minerals and Geopolitics

Minerals have also taken centre-stage in the global trade war. China is using its disproportionate control over rare earth materials to threaten the US and the rest of the world with the debilitating consequences of restricted supply.

Value addition: National Critical Mineral Mission of India

Objectives of NCMM

India’s Exploration Efforts

Way Forward for India

Mains Practice Question

Q  “In the age of the energy transition and digital revolution, control over critical minerals is the new oil.” Analyse. (250 words, 15 marks)
