As utilities operate to decarbonize the grid, long-duration energy storage can support them in smoothly integrating rising volumes of sustainable energy.
Fremont, CA: LDES innovations will flourish as the market for energy storage grows and diversifies. Their complementary worth and capability to supply many use cases with renewables are evident. Using clean earth-abundant raw materials (like iron, salt, and water) and readily available, domestically sourced industrial components improves the basic safety and sustainability of the products.
Greater manufacturing quantities will occur in significant cost reductions, all of which will lead to global deployment on a massive scale. Analysts in the sector emerge to agree on this point.
As progress is made in decarbonizing the electricity grid, long-duration storage can aid utilities in integrating increasing volumes of renewables. Some of the most strong LDES utility application cases include:
Solar and wind energy with time shifting
LDES can store surplus renewable energy generation and move it to times when its economic and resiliency worth is higher. Furthermore, storage aids in preventing curtailments from maximizing the benefits of renewable energy assets.
Smoothing intermittent renewables.
LDES's fast-response capabilities allow it to react instantly to changes in the renewable producing output by offering infinite charge-discharge capacity and a fast charge-discharge rate.
Increasing or substituting emissions-intensive peaker facilities.
Peaker plants generated with fossil fuels are the generators utilities activate when grid energy demand is at its peak. LDES can provide a reliable power source from intermittent renewables with sufficient duration, capacity, and cyclic flexibility to assist utilities in dodging the usage of polluting peaker plants.
Facilitating market participation
LDES can offer spinning reserves and even energy capacity as markets shift. LDES is also an adaptable asset capable of offering frequency regulation and other auxiliary services. For example, grid operator PJM's "10-hour rule" requires duration-limited non-generation resources, such as batteries, to deliver claimed capacity for up to 10 sequential hours. Commercially available long-duration storage can satisfy this requirement.
Microgrid stabilization and virtual power plant support
LDES enhances the dependability and adaptability of distributed energy resources. By decreasing or eradicating the need for diesel-powered backup generators.
