Military power generation and energy storage

Does the DoD need a microgrid energy storage system?

Jack Ryan, Program Manager for DIU. At present, the DoD is heavily dependent on mobile generators in a microgrid configuration for its tactical power systems, but has been lacking a systems-integrated energy storage solution that can enhance grid resilience, fuel efficiency, and optimize tactical generator performance.

Are military generators more efficient?

Military generators have standard sizes, but battery power and energy ratings are more flexible. Figure 6 shows the impact of varying ESS energy capacity on fuel consumption in the improved AC microgrid. Since the batteries do not have 100 percent efficiency, there are losses in each charge and discharge cycle.

How can the army support the energy demands of emerging technologies?

Supporting the energy demands of these emerging technologies requires a significant modernization and development of the U.S. Army’s microgrids. A microgrid is an independent energy system, which at a minimum consists of electrical generation and distribution assets.

What is a tactical energy storage unit?

When paired with AMMPS, the tactical energy storage unit helps further reduce the need for fuel, further reduces costs and most importantly it significantly increases the safety of troops in combat; because fewer fuel transport runs are required and the operation of the generators are quieter.

Which companies are developing energy solutions for ground soldiers?

Meanwhile, Spark Thermionics is developing electricity generation technology through thermionic energy conversion, while Xerion Advanced Battery is building “high-energy, fast-charging, lithium-ion batteries.” US Army Futures Command has selected four companies to develop lightweight energy solutions for ground soldiers.

Why does the Army need more power?

“The Army is requiring capabilities that meet its needs for greater mobility and adaptability for the future fight. We need to increase mission duration without further time burdens on Soldiers,” Vitale said. “Our research aims to address the challenge of making power adapt at the speed of the mission.”
