Summary:

The Long Duration Energy Storage (LDES) National Consortium provides a forum through which stakeholders across the LDES ecosystem can convene to identify barriers, determine potential synergies, and collaboratively develop and implement strategies necessary to achieve LDES technology commercialization within the next decade. The LDES National Consortium is comprised of National Laboratory and U.S. industry and community stakeholders, known as “Teaming Partners.” A Leadership Team powered by the knowledge, expertise, and relationships possessed by six U.S. National Laboratories guides a broad network of Teaming Partners to collaboratively develop a set of actionable recommendations to address identified challenges facing LDES technologies. Teaming Partners play a critical role in this LDES National Consortium by helping to define the key questions, issues, and outcomes that the LDES National Consortium must address to support the commercialization of LDES technologies. Currently, the Consortium has over 200 teaming partners. Teaming Partners are invited to participate directly through focus area groups that meet at least monthly called “Tiger Teams”. Tiger Teams are working collectively on various topics to identify and evaluate challenges in their specific focus areas, develop recommendations to address these challenges, and create impactful deliverables. Examples of Tiger Teams include Technology Development, Evaluation & Testing; Use Case Development; Market Planning; Economics & Valuation; Policy & Regulation; Investor Confidence & Finance; Demonstration & Deployments; Equity; Workforce Development; Customer Adoption; Supply Chain & Manufacturing Efficiencies; and Grid Infrastructure. Commercialization is defined as when a specific LDES technology and/or the LDES market is deemed to be self-supporting (i.e., no longer reliant on public funding or government subsidiaries). Barriers to commercialization include capital and operational costs, performance such as round-trip efficiency, private investment and project finance, markets, and deployments among others. This presentation will focus on use case development and outcomes of the LDES National Consortium that dealt with challenges of LDES commercial progress. Use case development started from the U.S. Department of Energy (DOE) LDES Liftoff report on six cases and added one case on industry electrification and nuclear energy integrating with LDES. The eight use cases include: 1) load management, 2) firming for power purchase agreements (PPAs), 3) microgrid resiliency, 4) utility resource planning, 5) transmission and distribution deferral, 6) energy market participation, 7) industrial electrification and nuclear energy integration. Those seven use cases are prioritized based on their abilities to improve energy reliability and reduce electricity cost, which are two primary factors for customer adoption of LDES technologies. This presentation will describe these use cases and rank their importance on grid resilience and economics for near-term and long-term electric supply scenarios.
