Summary of IEA's Special Report: Batteries and Secure Energy Transitions

Executive Summary

Batteries are essential for global energy transitions and decarbonization. Their costs have dropped by 90% since 2010, making them key in electric vehicles (EVs) and power storage. By 2030, battery demand could sevenfold in EVs and fivefold in storage. COP28 goals (tripling renewables, phasing out fossil fuels) require rapid battery deployment. Policy support and supply chain resilience are critical to meeting climate targets.

Chapter 1: Status of Battery Demand and Supply

Battery Demand Growth

• Global EV battery demand quadrupled by 2023.
• Utility-scale battery storage capacity surged due to renewable integration.
• Cost declines (90% since 2010) and performance improvements drove adoption.

Key Regions

• China dominates manufacturing (85% of cells), but Europe and the US are scaling up.
• Asia-Pacific, Europe, and North America lead in advanced battery tech.

Supply Chain Challenges

• High concentration of critical minerals (lithium, cobalt, nickel) in few countries.
• Price volatility risks supply stability. 100% of graphite comes from China.

Chapter 2: Outlook for Battery Demand and Supply

Renewable Energy Integration

• Batteries enable solar and wind penetration, facilitating tripling of renewables by 2030.
• Global storage capacity sixfold increase (1,500 GW in 2030) is needed for grid stability.

Falling Costs and Competitiveness

• By 2030, battery costs 40% lower, making them competitive with fossil fuels.
• Utility-scale batteries outperform coal and gas in some markets.

Key Growth Areas

• Decentralized systems (mini-grids, solar home systems) will expand access.
• New chemistries (sodium-ion, solid-state) offer alternatives to lithium-ion.

Chapter 3: Policy Implications and Recommendations

Critical Policy Actions

• Eliminate regulatory barriers for battery storage market participation.
• Ensure fair remuneration for flexibility services to incentivize deployment.
• Develop stable frameworks for consumer tariffs and virtual power plants (VPPs).

Supply Chain Resilience

• Diversify global mineral sources and invest in recycling to secure materials.
• Enhance responsible mining and recycling practices for sustainability.

Innovation and Investment

• Support R&D for next-gen batteries and circular economy initiatives.
• Provide financing tools to reduce costs in emerging markets.

Conclusion: Batteries are a linchpin for clean energy transitions. Scaling up deployment, overcoming supply chain bottlenecks, and enacting supportive policies are essential to meeting global climate goals.
