Categorical Exclusion (CX) Determinations By Date

Sabine Pass Liquefaction, LLC (SPL) filed an application (Application) with the Department of Energy's (DOE) Hydrocarbons and Geothermal Energy Office on March 25, 2026, seeking blanket authorization to engage in short-term exports of liquefied natural gas (LNG) previously imported into the United States from foreign sources.
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.
Funding will support the project team's small-scale research and development of protein exchange membrane (PEM) water electrolyzers to produce hydrogen by using new materials, designs, and manufacturing processes to overcome high operating and capital costs associated with conventional PEM water electrolyzers.
Freeport LNG Expansion L.P. and FLNG Liquefaction 4, LLC (collectively, FLEX4) filed a "Request for Extension of Non-Free Trade Agreement Export Commencement Deadline" (Request) with the Office of Fossil Energy and Carbon Management (now the Hydrocarbons and Geothermal Energy Office) on June 23, 2025, pursuant to section 3 of the Natural Gas Act (NGA) and 10 CFR Part 590 of the Department of Energy's (DOE) regulations.
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, an extended period of performance, and new project milestones to support the project team's small-scale research and development activities of an autonomous laboratory platform, "AlloyBot," intended to develop new structural alloys for energy and propulsion technologies with extreme operating conditions.
POWPOW, Inc. DBA Texas TEA Fuels and Lubes (Applicant) filed an application (Application) with the Department of Energy's (DOE) Hydrocarbons and Geothermal Energy Office (HGEO) on February 2, 2026, pursuant to section 3 of the Natural Gas Act (NGA) and 10 CFR Part 590 of DOE's regulations.
Navergy Infrastructure Partners LLC (Navergy) filed an application (Application) with the Department of Energy's (DOE) Hydrocarbons and Geothermal Energy Office (HGEO) on February 9, 2026, and Navergy filed a supplement to the Application on April 28, 2026.
This Third Amended Determination follows the approval of additional funding, an extended period of performance, a change of teaming partners, and new project milestones to support the project team's small-scale research and development activities of developing an energy storage and power generation (ESPG) system consisting of fuel-to-electric power conversion devices, metal-supported solid oxide fuel cells (SOFC) and turbogenerators, in progress under the Range Extenders for Electric Aviation with Low Carbon and High Efficiency (REEACH) Phase 2 Program.
