Quick Summary
The Defense Advanced Research Projects Agency (DARPA) is soliciting proposals for Promethean Clay, an initiative to develop revolutionary energy storage systems through a mechanical co-design framework. This program aims to eliminate the need for rigid, heavy exoskeletons in energy storage, leading to generational performance improvements, enhanced safety, and domestic sourcing. This is a Solicitation for Other Transaction for Prototype Agreements under 10 U.S.C. § 4022. Proposals are due May 6, 2026.
Opportunity Overview
DARPA seeks innovative approaches to energy storage that integrate mechanical and chemical design to achieve performance, safety, and operational stability in electrically powered technologies. The core idea is to treat energy storage as a mechanical system in addition to a chemical one, thereby obviating rigid materials and enabling free-form designs. The program specifically excludes evolutionary improvements, proposals focusing only on individual components, or new chemistries that do not address the rigid material challenge. The goal is to transition solutions to commercial production and government systems.
Key Requirements & Scope
- Mechanical Co-design: Develop systems where packaging materials act as hermetic interfaces, not rigid structures, allowing for free-form design.
- Performance Improvement: Achieve generational improvements in energy storage performance by reducing packaging fraction.
- Safety & Resilience: Incorporate thermal resilience and safety, maintaining or surpassing current standards.
- Domestic Sourcing: Ensure domestic sourcing pathways for all materials and manufacturing.
- Technical Challenge: Facilitate electronic and ionic transport processes through co-design, ensuring mechanical connectivity and uniform mechanical properties.
- Security: Proposers handling Controlled Unclassified Information (CUI) must demonstrate compliance with NIST SP 800-171 Rev. 2 (SPRS score 88+). An optional 3-month Phase 0 is available for security preparation.
Program Structure & Contract Details
The program is structured into three phases over 48 months: Phase 1 (24 months) for Power Source Design and Validation, Phase 2 (12 months) for Integration, and Phase 3 (12 months) for Application. Multiple awards are anticipated, with an estimated start date of August 1, 2026. The award instrument will be an Other Transaction for Prototype Agreement.
Submission & Evaluation
- Abstract Submission: Required as an initial screening step. The original abstract due date was March 11, 2026, but this has been superseded by Amendment 01. (Note: The XML metadata
responseDateof May 6, 2026, is for the full proposal). - Full Proposal Submission: Due May 6, 2026, by 1:00 PM ET.
- Oral Presentations: Anticipated May 5–14, 2026. Mandatory for all submissions, limited to 20 slides and 30 minutes, followed by a 45-minute Q&A.
- Evaluation Criteria: Abstracts are evaluated on Technical Concept and Potential. Full proposals are evaluated on Overall Scientific and Technical Merit, Potential Contribution and Relevance to DARPA Mission, and Budget and Price.
- Proposal Content: Volume I (Technical and Management Proposal) has a 10-page limit for written content, plus mandatory oral presentation slides. Volume II (Price Proposal) requires detailed cost breakdowns using provided templates (Attachments E, F, L, M).
Important Notes
- Set-Aside: None. Open competition, with encouragement for HBCUs, Small Businesses, etc.
- Eligibility: Non-U.S. organizations cannot participate. FFRDCs/UARCs can propose as prime or subcontractor.
