Energy Storage Capacity Will Increase 10-Fold

Could Energy Storage Capacity Really Increase By A Factor Of 10 By 2035?

The most critical component of global energy transition is storage infrastructure to balance intermittent production sources - solar and wind. This forecast anticipates that the globally installed energy storage capacity (including batteries, pumped hydro, and compressed air) will reach ten times its 2025 level by 2035. So, is this target realistic? Here’s a breakdown of the details.

2025 To 2035: Why A 10x Growth Projection?

Currently, much of global storage capacity comes from pumped hydroelectric plants. However, falling lithium-ion battery costs have accelerated grid-scale battery deployments since 2020. Nevertheless, by 2025, the majority of installed capacity still relies on traditional methods. As renewable energy installations increase, the need to store excess production during peak demand periods also grows proportionally. A tenfold increase represents a compound annual growth rate exceeding 25 percent - which is quite ambitious for 2030. Therefore, 2035 presents a more realistic timeframe for technological maturity and infrastructure transformation.

The Driving Forces Behind This Goal

Several powerful drivers are expected to contribute to this target:

• Lithium-ion Cost Reduction: A reduction in lithium-ion battery pack costs to below $100 per kilowatt-hour has increased economic viability. This decrease is accelerating the return on investment for storage projects and encouraging further deployments.
• Economies of Scale in the Electric Vehicle Sector: Growing demand for electric vehicles is dramatically increasing battery production capacity. This allows the same manufacturing lines to be used for grid storage, creating cost advantages.
• Policy Support: Many countries are establishing capacity markets and incentive mechanisms to enhance grid flexibility. These regulations make storage investments more attractive.

Challenges and Risks That Could Be Encountered

However, challenges are significant. Supply chain bottlenecks could arise for critical minerals like lithium, cobalt, and nickel. Furthermore, the existing grid infrastructure needs to be modernized to integrate these new storage facilities. Long-duration storage technologies - such as pumped hydro and compressed air - are crucial, particularly for seasonal balancing. The maturation and cost reduction of these technologies will be decisive in achieving the 2035 target.

Frequently Asked Questions

1. Why Is Energy Storage Capacity Growth Projected To 2035 Rather Than 2030?

This ambitious target requires a compound annual growth rate exceeding 25 percent - which would be difficult to achieve by 2030, considering current supply chain constraints and grid transformation rates. 2035 offers a more realistic timeframe for technological maturity, improved critical mineral supplies, and the completion of grid modernization.

2. Which Storage Technologies Will Contribute Most To This Growth?

Lithium-ion batteries will play a key role in short-term grid balancing. However, pumped hydroelectrics and compressed air systems are crucial for balancing needs lasting days or weeks. The combined deployment of these technologies will make the 10x growth possible.

3. What Is The Most Important Factor Increasing The Likelihood Of This Forecast’s Realization?

The reduction in lithium-ion battery costs to below $100 per kilowatt-hour has made storage economically viable. Combined with economies of scale in the electric vehicle sector, this cost decrease is the strongest driving force accelerating grid-scale storage deployments.
