Energy Storage Innovations Prize Round 2 | HeroX Energy Storage Innovations Prize Round 2 Propose transformative energy storage solutions that address niche markets and inform the DOE’s strategy to accelerate grid modernization.
Energy, Environment & Resources Energy, Environment & Resources Competitor Eligibility & Guidelines After a successful Round 1 , the U.S. Department of Energy (DOE) Office of Electricity (OE) is excited to announce Round 2 of the Energy Storage Innovations Prize is now open for submissions.
This single-phase, $300,000 competition aims to gain insights on innovative, emerging, and next-generation energy storage solutions that address niche markets and inform the DOE’s strategy on transformative storage technologies to accelerate grid modernization for all consumers, while achieving needed reliability, affordability, resilience, and energy security.
This competition places a focus on less conventional use cases (e.g., remote communities, extreme operating conditions) and innovative (less mature) energy storage technology solutions, across all duration scales, to advance the market landscape. Submissions will be judged on how innovative the use case and solution are, the strength of the plan, and other unique benefits.
Up to five Storage Innovations Champions will receive a $50,000 cash prize each and up to five Storage Innovations Finalists will receive a $10,000 cash prize each.
Competitor Eligibility & Guidelines The competition is open to individuals; academia, non-federal government entities, small businesses, start-ups, entrepreneurs, and other inventors who are working on nascent or emerging energy storage innovations that address less conventional use cases (e.g., serving communities in remote environments, extreme operating conditions) all subject to the full requirements in the Official Rules .
Past competitors of the Energy Storage Innovations Prize Round 1 are encouraged to reapply with updated submission materials; however, teams who won any phase of Round 1 are discouraged from submitting the same or similar idea to this round or any future round of the prize. Please review the Official Rules for the complete submission process and instructions for participating in this prize.
The Prize places a focus on less conventional use cases (e.g., remote and/or electrically-vulnerable communities, extreme climates) and innovative (less mature) energy storage technology solutions, across all duration scales, to advance the market landscape. DOE is not providing a list of “less conventional use cases” that are eligible for this prize.
The prize submission must demonstrate that the use case is less conventional and clearly differentiate how the innovative technology solution solves a problem for a market, community, sector, or other group that is significantly different from conventional applications of that technology. The energy storage technologies eligible for consideration in a solution are not limited but must discharge electricity.
Below are examples of eligible energy storage technologies. However, other technologies beyond those listed are of interest to DOE.
Type Technology Other Other technologies beyond those listed below are of interest Electrochemical Redox flow Lead-acid Sodium ion Zinc ion Li-metal Na-metal Other metals (e.g., Mg, Al) Reversible fuel cells Supercapacitors Lithium-ion Electromechanical Liquid air energy storage Flywheels Geomechanical Pumped storage hydropower Compressed-air energy storage Gravitational Thermal Phase change Low-temperature storage High-temperature sensible heat Thermal-photovoltaic Chemical Chemical carriers (e.g., ammonia) Hydrogen Flexible buildings Thermostatically controlled loads Building mass Ice and chilled water Organic phase change material Salt hydrate Thermochemical Desiccant Flexible generation Front-of-the-meter flexibility and hybrids Behind-the-meter hybrids Submission Deadline This Friday March 13 March 11, 2026, 11 a.
