Jumpstart Opportunities to Unleash Leadership in Energy Storage with 1K Energy Storage Systems (JOULES-1K) Phase 2 is sponsored by U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E). This program supports projects in Phase 2 that demonstrated the most promise to develop energy storage chemistries in 1 kWh test articles and thorough 1 MWh hour performance and cost models.
JOULES-1K targets '1K-class' systems capable of achieving energy density equal to or exceeding 1,000 watt-hours per kilogram and 1,000 watt-hours per liter at end of life and at the net-energy system level. Technologies must be fundamentally distinct from conventional battery approaches.

Past winners and funding trends for this program
The Small Business Innovation Research (SBIR) program at ARPA-E is a grant from the U.S. Department of Energy's Advanced Research Projects Agency-Energy that funds small businesses developing transformational energy technologies. Phase I awards reach up to approximately $314,363 for initial feasibility research, while Phase II awards can reach approximately $2,095,748 for further development. ARPA-E SBIR also connects to SCALEUP, ARPA-E's early commercialization program, for technologies ready to scale toward market. Eligible applicants are U.S. small businesses with innovative energy technology concepts spanning clean power, energy storage, transportation, and related areas. Applications are submitted through the DOE Funding Opportunity Exchange, and ARPA-E emphasizes high-impact, high-risk technology development that could reshape the energy landscape.
Seeding Critical Advances for Leading Energy technologies with Untapped Potential (SCALEUP) Ready is sponsored by U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E). Supports the scaling of high-risk and potentially disruptive new technologies across the full spectrum of energy applications. This NOFO focuses only on scale-up and pre-pilot projects of promising technologies that ARPA-E has previously funded.
On August 24, 2026, DOE and SBA signed a memorandum of agreement creating the Small Business Investment Company-Energy Initiative, pointing a $58 billion SBA-leveraged investment program at DOE's technology priorities. No application, no NOFO, no deadline. Here is how SBIC capital actually works, why a January 2026 rule change made this possible, and what a company sitting on a DOE Phase II award should do about it.
Read articleThe Hydrocarbons and Geothermal Energy Office's University Training and Research program funds coal, oil and gas, and geothermal R&D at U.S. colleges and universities — but every proposal must include a non-academic partner and must build training modules that outlive the award. The LOI deadline is October 1, 2026, with full applications 15 days later. Here is what that compressed window means and why the workforce framing changes what a competitive proposal looks like.
Read articleOn April 20, 2026, the White House declared grid, natural gas, LNG, petroleum, and coal 'essential to national defense,' unlocking DPA Title III loans, loan guarantees, and purchase commitments through DOE. Here is how this non-traditional financing works, who qualifies, why the September 30 sunset matters, and how energy companies and their supply chains should position now.
