Overview
- The Defense Innovation Unit awarded Pratt Miller a contract on July 30 to prototype the Expeditionary Hydrogen On Ship & Shore (EHOSS) system in a containerized form factor
- The unit uses a proton exchange membrane electrolyzer to produce over 20 kilograms of hydrogen daily, compress gas to 700 bar and store it in conformable tanks for low-heat, low-noise operations
- EHOSS establishes a self-sufficient micro hydrogen supply chain adaptable to remote, wide-range contested environments without dependence on external fuel convoys
- Initial trials, including solid-state storage evaluations using nanomaterials, are scheduled for later this year to demonstrate field performance
- The project unites DIU with U.S. Indo-Pacific Command, the Marine Corps Expeditionary Energy Office and research teams from the Navy and Army
