Industrial Energy Storage Systems Prize — Phase 3: Validate

The Industrial Energy Storage Systems Prize – Phase 3: Validate is a cash prize administered by the U.S. Department of Energy (DOE) Industrial Technologies Office (ITO) through the HeroX platform. It is the third and final phase of the three-phase Industrial Energy Storage Systems Prize, a $4.8 million challenge seeking cost-effective energy storage concepts for industrial facilities that enhance energy efficiency and are applicable across industrial sectors. DOE's ITO manages the prize to advance industrial decarbonization by identifying storage solutions that can be deployed broadly across U.S. industry. Phase 3 winners each receive $400,000 in cash. There is no cost-sharing requirement — the prize award is granted directly to winning teams. Only teams that won Phase 2 (Advance) are eligible to compete in Phase 3. The Phase 2 prize was $200,000 per winning team, and Phase 1 was $100,000 per winning team. No per-phase pool breakdown is published separately from the overall $4.8 million program total. Eligibility is broad: the competition is open to individuals; private entities (for-profits and nonprofits); non-federal government entities such as states, counties, tribes, and municipalities; and academic institutions. Competitors must have won Phase 2 to enter Phase 3. There is no company size, revenue, or age restriction stated in the source. Phase 3 teams demonstrate the prototype of their innovation and identify future scalability. Applications are submitted through the HeroX platform at herox.com/industrial-energy-storage. The challenge page notes the challenge is closed to new competitors, and no future rounds or successor calls have been announced. Practical note: this challenge is closed. The HeroX page no longer accepts new entries. Teams that did not progress through Phase 1 and Phase 2 cannot enter at Phase 3. No specific submission deadline dates are stated on the source page.

Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
