Government policy plays a critical role in the adoption and advancement of long-duration energy storage (LDES) by providing funding, setting procurement targets, mandating regulatory frameworks, and fostering demonstration and deployment projects. Key aspects include:
Financial Support and Investment Programs
- Government programs allocate significant funds to accelerate LDES technologies. For example, California’s Long Duration Energy Storage Program has dedicated over $270 million towards demonstration and deployment of non-lithium-ion LDES technologies to diversify storage portfolios and support market growth.
- At the federal level, the U.S. Department of Energy (DOE) runs portfolios and pilot programs intended to overcome technical and institutional barriers to commercial viability. These include demonstration projects on government facilities and support for a wide variety of technologies, aimed at increasing grid resilience and reliability with 10+ hour energy delivery capacity.
Policy Targets and Procurement Mandates
- Many U.S. states have established legally binding or aspirational procurement targets for energy storage capacity, encouraging utilities to acquire increasing amounts of storage by certain deadlines. Twelve states, including California, New York, Massachusetts, and Nevada, mandate specific quantities of energy storage procurement.
- More recently, some states have started explicitly incorporating long-duration storage (defined generally as 8-10 hours or more discharge duration) into these targets to address the unique needs of decarbonizing the grid with intermittent renewables like solar and wind.
Regulatory and Market Frameworks
- Governments help adapt regulations to enable the integration of LDES into the energy market, ensuring that long-duration storage resources can participate fairly in grid services, capacity markets, and ancillary services.
- Policies may also include consumer protections and incentives to encourage deployment at various scales, including utility-scale and distributed energy resources.
Demonstration and Deployment Programs
- Federal and state-led demonstration projects help validate new LDES technologies in real-world environments, paving the way for wider commercial adoption by reducing risk and showing feasibility.
- Programs coordinated between agencies such as DOE and the Department of Defense expand the testing and use of LDES in critical government infrastructure.
Summary
Government policy shapes the landscape for long-duration energy storage adoption by:
- Providing funding and support for technology development and demonstrations, reducing commercialization risks.
- Setting mandatory or aspirational procurement targets that drive utility-scale deployment.
- Establishing regulatory frameworks that integrate LDES into energy markets effectively.
- Encouraging diverse LDES technologies beyond lithium-ion batteries to meet the grid’s evolving needs for sustained renewable integration and reliability.
These policies collectively enable the scaling of LDES as an essential component for a more resilient, reliable, and clean electricity grid.
