Military energy storage plus photovoltaic

What are the benefits of a multimegawatt solar PV system?

Economically replace a portion of natural gas used for thermal loads and further reduce an installation’s CO2 footprint. Accomplishing these benefits requires multimegawatt BESS with multiday durations coupled to utility-scale solar PV. An on-base utility-scale solar PV requires a large tract of available land.

Can a solar PV system reduce dependence on diesel fuel?

This study found that eliminating dependence on diesel fuel would require 100–400 acres of available land, a requirement easily met at some but not all military installations. The size of the required solar PV can be reduced by deploying a hybrid system with a small amount of diesel generation.

What if only 300 acres are available for solar PV?

If only 100 or 200 acres are available for solar PV, Antora Energy’s BESS duration would need to be increased to thousands of hours. If only 300 acres are available a system can be designed with a positive NPV but roughly a third of the unconstrained result. The required BESS are large, multimegawatt batteries with multiday durations.

Does a base need a large solar PV system?

The systems all require large utility-scale solar PV. The area required for such large solar PV is not expected to be an issue at a base like Fort Bliss or Holloman AFB, but a base like Patuxent River NAS might not be able to accommodate such a large solar PV, which requires 414 acres.

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.

Should military installations use Antora energy's LDEs battery?

It yields an NPV that is more than $20 million higher than the electric-energy-only case. This allows the optimized system to use a larger solar PV and does not compromise the electric energy resiliency. This study assessed the potential value for military installations of a future commercial version of Antora Energy’s LDES battery.
