Categorical Exclusion Determinations: Advanced Research Projects Agency-Energy

This Second Amended Determination follows the approval of an extended period of performance and removal of two teaming partners to develop a catalyst-enabled, economical technology that will reduce emissions from ventilation air methane associated with coal mining, in progress under the Reducing Emissions of Methane Every Day of the Year (REMEDY) program.
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]) are 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 Fourth Amended Determination follows the approval of additional funding, extended period of performance, a new project team member, and additional project milestones to support one project team's small-scale research and development activities to further advance their NuCycle used nuclear fuel recycling process under the Converting Used Nuclear Fuel (UNF) Radioisotopes Into Energy (CURIE) program.
Funding will support the project team's small-scale research and development of solvent-free methods for manufacturing high-selectivity flow battery membranes using chemical vapor deposition, which could reduce costs and improve performance of redox flow batteries for utility scale grid storage and potential applications for metals separation and desalination.
This Amended Determination follows the approval of additional funding, period of performance, and new project milestones to support the project team's small-scale research and development activities to finalize their software to model and simulate construction performance using as-planned Building Information Modeling (BIM) and as-built point clouds of off-site components by employing automated data collection solutions for capturing as-built conditions of pre-fabricated components using robotics and visual sensors.
