The Disruptive DC Converters for Grid Resilient Infrastructure to Deliver Secure energy (DC-GRIDS) program supports the small-scale research and development of more compact and cost effective power electronics converters for direct current (DC) transmission to transport electricity over longer distances with less electricity lost during conveyance from generator to user.
The Jumpstart Opportunities to Unleash Leadership in Energy Storage with 1K Energy Storage Systems (JOULES-1K) Phase 2 Program (previously Pioneering Railroad, Oceanic and Plane ELectrification with 1K energy storage systems [PROPEL-1K]) consists of projects chosen from Phase 1 of the JOULES-1K program which show the most promise of developing novel energy storage to support drones, robots, Electrical Vertical Take-Off and Landing (eVTOL) aircraft, and other applications that would benefit from ultra-high-density storage systems.
This Amended Determination follows the approval of additional funding, extended period of performance, a new teaming partner, and new project milestones to support the project team's small-scale, research and development activities of an alloy that can meet critical property requirements, such as operation at very high temperatures (750°C or higher), for use in liquid-fueled molten salt reactors and fluoride-salt cooled high temperature reactors.
