Long-Duration Energy Storage Demonstrations

The Bipartisan Infrastructure Law appropriates $505 million for the development of long-duration energy storage (LDES) demonstrations to validate new technologies and enhance the capabilities of customers and communities to integrate grid storage more effectively. DOE defines LDES as systems capable of delivering electricity for 10 or more hours in duration.

Funding for this portfolio of LDES demonstrations provides a significant boost for DOE to greatly expand support for demonstration and deployment of LDES technologies to increase availability and deliver affordable, reliable clean electricity. In particular, this funding will help advance LDES systems toward widespread commercial deployment by providing an opportunity for nascent LDES technologies to overcome the technical and institutional barriers that exist for full-scale deployment with a focus on a range of different technology types for a diverse set of regions.

Cheaper LDES can increase local control of the power system, build resilience for communities, minimize power grid disruptions, and help reach President Biden’s goal of 100% clean electricity by 2035 and net-zero emissions by 2050.

Eligible Uses

OCED’s LDES portfolio is focused on a range of technologies with regional diversity to demonstrate promising technologies at different scales and help innovative LDES technologies to become commercially viable. These demonstrations will contribute to one or more of the following:

To improve the security of critical infrastructure and emergency response systems.
To improve the reliability of transmission and distribution systems, particularly in rural areas, including high-energy cost rural areas.
To optimize transmission or distribution system operation and power quality to defer or avoid costs of replacing or upgrading electric grid infrastructure, including transformers and substations.
To supply energy at peak periods of demand on the electric grid or during periods of significant variation of electric grid supply.
To reduce peak loads of homes and businesses.
To improve and advance power conversion systems.
To provide ancillary services for grid stability and management.
To integrate renewable energy resource production.
To increase the feasibility of microgrids (grid-connected or islanded mode).
To enable the use of stored energy in forms other than electricity to support the natural gas system and other industrial processes.
To integrate fast charging of electric vehicles.
To improve energy efficiency.
