Lithiumstart Wins US Navy Energy Storage Module (ESM) Program

Lithiumstart's BluFlex Energy Storage System (ESS) has been selected for the US Navy DDG51 Energy Storage Module (ESM) program. The ESM enables fuel savings and new mission capabilities for the DDG51 class ships. Lithiumstart has been contracted by DRS Technologies Inc, the prime contractor to the Navy, to provide the lithium ion battery ESS component of the ESM. DRS will package Lithiumstart's ESS along with the DRS Power Electronic Modules (PEM's) to provide an integrated solution to the Navy. The combined solution offers third generation technology proven in the field, and a high level of safety including multi- year DoD investments in Lithiumstart's ESS modules.

The Lithiumstart ESS is comprised of scalable 48V modules which stack together to reach up to 2KV, and 100MW+.  The battery modules and BluFlex Battery Management System (BMS) platform are based on commercialized military technology deployed with 14 militaries worldwide.

DRS Technologies to Supply Energy Storage Modules for U.S. Navy DDG-51 Ships Under Contract Award


ARLINGTON, VA, April 7, 2014  ̶  DRS Technologies Inc., a Finmeccanica Company, announced today it will be providing electric power support for the U.S. Navy’s DDG 51 class ships by designing and building Energy Storage Modules (ESM) that will function as a ship-wide uninterruptable power supply.

The initial $17 million contract was awarded by the U.S. Naval Sea Systems Command to DRS’s Power and Control Technologies business, a leader in developing and manufacturing products and systems that generate, distribute, convert and control electric power for naval and marine platforms. The contract will include design, engineering and associated support for the energy storage system and includes options which, if exercised, would bring its total value to more than $88 million.

“We are very excited to have this opportunity to develop this large energy storage system for the U.S. Navy,” said Roger Sexauer, President of the DRS Maritime and Combat Support Systems Group.  “This ESM system is a great initiative by the Navy which should offer tremendous fuel savings for naval surface combatants. We are happy to participate as the Navy’s partner in this important development effort.”

DRS will design, manufacture and qualify the ESM systems which will allow the ship’s electric plant to run on one versus two gas turbine generators under certain conditions to conserve fuel while maintaining vital power in the event of a generator failure. The Navy plans to retrofit this system on the existing flight I and II DDG 51 class ships. The ESM system is yet another example of DRS’ focus on supporting continuity of power for the Navy’s ships.
DRS Power & Control Technologies, Inc. has installed equipment on every U.S. Navy combatant ship since World War II, including nuclear-powered and conventionally-powered ships and submarines.
