Summary of "Batteries and Secure Energy Transitions" by the International Energy Agency

Core Content

The International Energy Agency (IEA) report Batteries and Secure Energy Transitions highlights the pivotal role of batteries in driving the global energy transition and enhancing energy security. Batteries are identified as a key enabler of clean energy systems, supporting the expansion of renewable energy, the electrification of transport, and the modernization of power grids. The report outlines the current status and future outlook of battery demand and supply, emphasizing the need for policy support, investment, and supply chain diversification to meet global climate and energy goals.

Main Views

• Batteries as a cornerstone of the energy transition: Batteries are essential for achieving the goals set at COP28, including tripling renewable energy capacity by 2030 and transitioning away from fossil fuels.
• Significant growth in battery deployment: In 2023, battery storage in the power sector grew more than double year-on-year, reaching 42 GW globally. EV battery deployment increased by 40%, with 14 million new electric cars added.
• Lithium-ion dominance and cost reductions: Lithium-ion batteries dominate both EV and storage applications due to their high energy density and long lifespan. Costs have fallen by 90% since 2010, making them a cornerstone of modern economies.
• Cost-competitive future: By 2030, battery costs are expected to decline by another 40%, making them more affordable for various applications. Solar PV plus batteries are already competitive with new coal in India and will soon be competitive with new coal in China and new natural gas in the US.
• Energy security benefits: Battery storage enhances electricity security by providing short-term flexibility and grid stability. It also reduces the need for imported fossil fuels, increasing energy self-sufficiency.

Key Information

1. Status of Battery Demand and Supply

• Global battery demand: The energy sector now accounts for over 90% of annual lithium-ion battery demand, up from 50% in 2016.
• EV and storage applications: In 2023, there were nearly 45 million EVs on the road and over 85 GW of battery storage in use globally.
• Battery cost trends: Lithium-ion battery prices have dropped from USD 1400/kWh in 2010 to less than USD 140/kWh in 2023.
• Chemistry diversity: LFP batteries are becoming more prominent, especially in storage, due to their lower cost and reduced reliance on critical minerals like nickel and cobalt.

2. Outlook for Battery Demand and Supply

• COP28 targets: To meet the goals of tripling renewable energy capacity and doubling energy efficiency improvements, energy storage needs to increase sixfold by 2030, with batteries accounting for 90% of this growth.
• Battery storage growth: In the NZE Scenario, battery storage capacity is projected to rise 14-fold to 1200 GW by 2030, with utility-scale storage being a major driver.
• EV battery growth: EVs are expected to grow significantly, with a projected 25% annual increase in battery storage deployment to support this.
• Chemistry evolution: Sodium-ion batteries are gaining traction due to their lower costs and reduced use of lithium, while solid-state batteries are anticipated to become commercially available beyond 2030.

3. Policy Implications and Recommendations

• Policy support is critical: Governments are playing a key role in promoting battery adoption through incentives and legislation, such as the Inflation Reduction Act, Net Zero Industry Act, and Production Linked Incentive.
• Supply chain challenges: Battery manufacturing and critical mineral supply remain concentrated in a few countries, notably China, which holds over 85% of global battery cell production. Diversification and sustainability of supply chains are necessary.
• Market expansion: Battery markets are expanding rapidly, especially in emerging economies, where decentralized solutions like solar home systems and mini-grids are helping achieve universal electricity access.
• Emissions impact: In the NZE Scenario, about 60% of CO₂ emissions reductions in 2030 are linked to batteries, making them a key technology for climate goals.

Conclusion

Batteries are set to play a central role in the global shift to secure and sustainable energy systems. Their affordability, performance, and versatility are key to supporting the energy transition, particularly in transport and power. To achieve the ambitious targets of COP28, the world must scale up battery production and deployment, diversify supply chains, and continue to support innovation and policy frameworks that enable their widespread use.
