Promote affordable energy storage systems

What are energy storage technologies?

Energy storage technologies have the unique capabilities to keep the lights on when the power grid is under stress. In both Texas and California, energy storage technologies have prevented black outs during significant heatwaves—keeping people safe, power affordable, and the power on for businesses.

Why do we need a co-optimized energy storage system?

The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply, necessitate advances in analytical tools to reliably and efficiently plan, operate, and regulate power systems of the future.

Does storage reduce electricity cost?

Storage can reduce the cost of electricity for developing country economies while providing local and global environmental benefits. Lower storage costs increase both electricity cost savings and environmental benefits.

What is the future of energy storage?

According to 'The Future of Energy Storage' report by the MIT Energy Initiative (MITEI), government investment in sophisticated analytical tools is urged to plan, operate, and regulate electricity systems efficiently, enabling the deployment and use of storage.

Why is energy storage more expensive than alternative technologies?

High capital cost and low energy density make the unit cost of energy stored ($/kWh) more expensive than alternatives technologies. Long duration energy storage traditionally favors technologies with low self-discharge that cost less per unit of energy stored.

Why is Doe investing in energy storage?

The underlying motivation for DOE’s strategic investment in energy storage is to ensure that the American people will have access to energy storage innovations that enable resilient, flexible, affordable, and secure energy systems and supply, for everyone, everywhere.
