Abstract RCT Systems led a team that included Creative Energy Solutions, and NDI Engineering in the development of an Advanced Energy Storage Module (ESM) for the Office of Naval Research (ONR) under a Broad Agency Announcement (BAA) contract for a DDG 51 Fuel Efficiency Demonstrator. The project demonstrated a modular 600kW ESM in December 2010. These modules could be combined into a 3 MW system to allow DDG 51 single generator operations, providing full ship backup power for up to 10 minutes with significant fuel savings. These savings are dependent on the ship operating profile. The BAA assumed 4,000 hours per year per ship of single generator operations. Based on that estimate, the system could facilitate savings of approximately 8000 BBL of Fuel/ship/year, or up to approximately $1.3M/ship/year in direct fuel savings at Jan 2012 DLA Fuel Rates of $160/bbl. This equates to approximately 30% direct savings in the ships electric plant fuel usage during peace time cruise and an 8% savings in overall ships fuel usage based on Navy Incentivized Energy Conservation (I-ENCON) reports. DoD has mandated the use of Fully Burdened Fuel Cost (FBFC) in all future acquisition decisions. FBFC savings could be as high as $3-5M/ship/year in FY-12 Dollars. We estimate that hardware costs alone could be recouped in approximately 2 years based on FBFC savings. Navy testing at NSWCCD SSES DDG-51 Land Based Engineering Site (LBES) is ongoing, and it is planned to install the ESM in a DDG-51 Class ship in summer/fall of 2012 for an at sea demonstration. The Navy is currently determining the total energy required to be available to satisfactorily de-risk single generator operations on DDG-51 Class ships. While designed for DDG 51, the modular system is potentially adaptable to all Navy and commercial ships, and supports the Next Generation Integrated Power System (NGIPS) Architecture.
