The DOE Long Duration Energy Storage Shot is a U.S. Department of Energy objective focused on reducing the cost of 10-plus-hour grid storage by 90%. Delivery was structured through the Office of Clean Energy Demonstrations. It used a $349 million Demonstrations Program announced in 2022 and a $100 million Pilot Program announced in 2024. For these opportunities, for-profit firms, nonprofits, universities, and research organizations in the United States were included, while individuals were excluded. The latest cycle is not currently active, and no 2026 successor notice is identified in the current materials. The initiative remains a historical and technical precedent for long-duration storage teams rather than an openly announced continuing call.
