Can long-duration energy storage (LDEs) meet the DoD's 14-day requirement?

This report provides a quantitative techno-economic analysis of a long-duration energy storage (LDES) technology, when coupled to on-base solar photovoltaics (PV), to meet the U.S. Department of Defense’s (DoD’s) 14-day requirement to sustain critical electric loads during a power outage and significantly reduce an installation’s carbon footprint.

What is long-duration energy storage (LDEs)?

The Advanced Research Projects Agency–Energy (ARPA-E), though its Duration Addition to electricitY Storage (DAYS) program (2), has invested in long-duration energy storage (LDES) systems with a focus on meeting the future needs of the grid. One such technology, developed by Antora Energy (3), stores thermal energy in carbon blocks.

Where can I find a report on long-duration energy storage?

This report is available at no cost from the National Renewable Energy Laboratory (NREL) at Marqusee, Jeffrey, Dan Olis, Xiangkun Li, and Tucker Oddleifson. 2023. Long-Duration Energy Storage: Resiliency for Military Installations. Golden, CO: National Renewable Energy Laboratory.

How will energy storage impact resiliency?

In addition, the large energy storage expected to be required to meet DoD resiliency goals will result in a BESS that has no need to use most of its SOC while grid tied to yield economic value. A higher minimum SOC will lead to a higher survival probability at 14 days, and a lower SOC minimum will lead to

How much electricity does a military installation use?

Typical mid-size to large active military installations’ peak electric loads range from 10 to 90 MW, and their critical electric loads range from approximately 15% to 35% of the total electric load. Figure 6 illustrates conditions seen on seven different mid-size to large military installations. Figure 6.

How much energy does the DOD use?

Energy is essential for DoD’s installations, and DoD is dependent on electricity and natural gas to power their installations. In fiscal year 2022 (20), DoD’s installations consumed more than 200,000 million Btu (MMBtu) and spent $3.96 billion to power, heat, and cool buildings.
