Why in the News ?

Recent global geopolitical tensions, including trade wars, supply chain disruptions, and mineral export restrictions, have exposed India’s heavy dependence on battery energy storage systems (BESS) dominated by China. This has triggered debates on diversifying energy storage technologies to ensure energy security, resilience, and sustainable renewable integration.

Context: Energy Transition and Storage Imperatives

  • Energy transition necessity: India is rapidly shifting toward renewable energy (RE) sources such as solar and wind to meet its climate commitments and reduce fossil fuel dependence.
  • Intermittency challenge: Renewable sources are variable in nature, requiring efficient energy storage solutions to maintain grid stability.
  • Growing demand: With rising electrification, urbanisation, and industrialisation, India’s need for reliable energy storage systems is increasing.
  • Policy push: The government has promoted Battery Energy Storage Systems (BESS) as a key solution for grid-scale storage.
  • Strategic vulnerability: However, heavy reliance on imported storage technologies creates strategic and economic risks.

About Energy Storage and Policies:

Key points

●      Energy Storage Systems (ESS): Technologies that store excess energy and release it when required, ensuring continuous power supply.

●      Battery Energy Storage System (BESS): Uses electrochemical batteries (lithium-ion) for grid-scale storage and renewable integration.

●      Pumped Hydro Storage (PHS): Stores energy by pumping water to higher elevation and generating electricity during release.

●      Green Hydrogen: Produced via electrolysis using renewable energy, acts as a clean fuel and storage medium.

●      Grid Stability: Ability of power systems to maintain balance between demand and supply, preventing outages.

●      Intermittency: Refers to the fluctuating nature of solar and wind energy, requiring backup storage.

Important Minerals for Energy Storage

●      Lithium: Key element in lithium-ion batteries, crucial for energy density and efficiency.

●      Nickel: Improves energy storage capacity, enabling longer battery usage.

●      Copper: Essential for electrical conductivity in batteries, grids, and EVs.

●      Strategic concern: These minerals are geographically concentrated, increasing import dependence.

Key Policies and Initiatives

●      National Green Hydrogen Mission (2023): Aims to make India a global hub for hydrogen production and export.

●      PLI Scheme for Advanced Chemistry Cells (ACC): Promotes domestic manufacturing of batteries to reduce imports.

●      National Electricity Policy: Focuses on grid modernisation, renewable integration, and storage expansion.

●      Atmanirbhar Bharat Abhiyan: Encourages self-reliance in critical sectors, including energy technologies.

●      Policy goal: Achieve energy security and sustainability through diversification.

Global Context

●      China’s dominance: Controls major share of battery manufacturing and mineral supply chains.

●      US-China trade tensions: Highlight risks of overdependence on global supply chains.

●      Energy geopolitics: Increasing use of trade restrictions and resource control as strategic tools.

●      Supply chain vulnerability: Disruptions can impact energy infrastructure and economic stability.

●      Need for diversification: Countries like India must ensure resilient and secure energy systems.

 

Global Supply Chain Risks and Geopolitical Concerns

  • Weaponisation of trade: Recent events such as US-China trade tensions and tariff wars highlight how economic interdependence can be exploited geopolitically.
  • Critical mineral control: China dominates supply of lithium, cobalt, nickel, and copper, essential for battery manufacturing.
  • Supply disruptions: Export restrictions by China have caused global supply shocks, affecting countries like India.
  • Energy insecurity risks: Dependence on foreign inputs exposes India to price volatility and supply uncertainty.
  • Recent examples: Events like the Hormuz Strait crisis affecting hydrocarbons show that energy supply chains are highly vulnerable.

Dominance of Battery Energy Storage Systems (BESS)

  • Technological leadership: China leads in battery technology, manufacturing capacity, and global market share.
  • End-to-end control: Its dominance extends from mining to processing to final battery production.
  • Cost advantage: Economies of scale give China a significant price advantage, making alternatives less competitive.
  • India’s dependence: India imports a large share of battery components and critical minerals.
  • Strategic risk: Over-reliance on BESS creates single-point vulnerability in energy infrastructure.

Alternative Energy Storage Technologies

Pumped Hydro Storage (PHS)

  • Uses excess electricity to pump water to elevated reservoirs.
  • Generates power when water flows down through turbines.
  • Advantages: Proven technology, long lifespan, large-scale capacity.
  • Limitations: Requires specific geography, involves high capital cost, and risks ecological disruption. Projects often require environmental clearances under the EIA notification and compliance with the Forest Conservation Act.

Concentrated Solar Power (CSP) with Thermal Storage

  • Uses mirrors to concentrate sunlight and generate heat stored in molten salts.
  • Heat can later produce steam for electricity generation.
  • Advantages: Enables continuous solar power, reduces intermittency.
  • Limitations: High initial cost and limited deployment in India.

Green Hydrogen-Based Storage

  • Renewable energy splits water into hydrogen and oxygen (electrolysis).
  • Hydrogen stored and used in fuel cells or turbines.
  • Advantages: Clean fuel, versatile applications, reduces emissions, contributes to a pollution free environment.
  • Emerging potential: Could replace fossil fuels in transport and industry.

Green Hydrogen: A Strategic Game Changer

  • Energy carrier: Hydrogen acts as a long-duration energy storage medium.
  • Decarbonisation tool: Produces water vapour instead of CO₂, aiding climate goals.
  • Multiple applications:

○       Power generation (combined-cycle turbines)

○       Transport (fuel cell vehicles)

○       Industry (steel, fertilisers)

  • Energy independence: Reduces reliance on imported fuels and battery materials.
  • Policy importance: India’s National Green Hydrogen Mission aims to scale production and reduce costs.
  • Challenges remain: High production cost, infrastructure gaps, and technological barriers.

Economic and Strategic Implications for India

  • Cost-security trade-off: Cheap imports may reduce costs but increase strategic vulnerability.
  • Energy sovereignty: Indigenous technologies are crucial for long-term security.
  • Industrial policy need: India must build domestic capacity in storage technologies and critical minerals.
  • Innovation ecosystem: Encouraging R&D in alternative storage solutions is essential.
  • Diversification strategy: Reducing dependence on a single technology or country is critical.
  • Resilience building: Energy systems must withstand global shocks and disruptions.

Need for Policy Shift and Diversification

  • Balanced approach: Limit BESS to essential grid functions, diversify for other uses.
  • Technology-neutral policy: Encourage multiple storage technologies.
  • Domestic manufacturing push: Promote Atmanirbhar Bharat in energy storage.
  • Strategic reserves: Build stockpiles of critical minerals.
