The Department of Defense, specifically the Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC), intends to award a sole source contract to Ocean Pacific Technologies (OPT) for the provision of their patented fully ceramic water lubricated axial piston pump (APP) and motor (APM). This procurement aims to support particle wear resistance testing for pumped hydropower energy storage (PHES) systems at the NAVFAC EXWC Seawater Desalination Test Facility, which is critical for evaluating the operational longevity and performance of these systems under particulate loading conditions. The successful implementation of this technology is expected to enable cost-effective scaling of PHES to microgrid installations, enhancing long-duration energy storage capabilities. Interested parties may contact Kitty Candelaria at kitty.l.candelaria.civ@us.navy.mil or Nicole M. Mendes at nicole.m.mendes2.civ@us.navy.mil for further information, with the anticipated award date set for on or before December 31, 2025.
