Military high power energy storage system

What is a LDEs-based power system?

The LDES-based system modeled in this report is a complex power system. The system includes Antora Energy’s BESS and a utility-scale solar PV. Antora Energy’s BESS has a thermal storage unit, TPV modules that generate DC power, a set of inverters to transform the DC power to AC, and a transformer.

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.

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.

What are the different types of energy storage options?

Energy storage options considered were batteries, capacitors, and flywheels. The study compared how quickly the stored energy can be used, the amount of energy stored for a given size and weight (energy density), size, weight, discharge, and recharge rate.
