Long-Duration Energy Storage (LDES) Battery System

O que a entidade adjudicante procura

INTRODUCTION Idaho National Laboratory (INL) and Argonne National Laboratory (ANL) are seeking information from organizations that can provide long-duration energy storage (LDES) battery systems for benchmark performance testing at National Laboratory facilities. This EOI aims to identify qualified technologies and suppliers, inform technical planning, and refine subsequent acquisition steps. BACKGROUND Idaho National Laboratory (INL) and Argonne National Laboratory (ANL) are seeking LDES technologies that will undergo benchmark performance testing at their facilities. Acceptable technologies include rechargeable electrochemical battery systems that: Can be configured into a module dimension, namely, 100-150 kWh, that can sustain 10-15 kW over ten hours. LxWxH shall not exceed 7x7x7 ft. Two such modules are sought. Can be configured into a full-size dimension, namely, 1000-1500 kWh, that can sustain 100-150 kW over ten hours. Anticipated dimension is one 40-ft shipping container, or two 20-ft containers. One such full-size system is sought. Can be operated between 0 to 50 ºC without more than 20% loss in power performance and 20% more aging (energy capacity loss) than that observed at a baseline condition of operating at 25 ºC. Provide an AC/DC interface that facilitates testing and logging of all system parameters, Will arrive at INL and ANL sites as pre-built systems, with only minor connections required prior to operation, has a lifetime under typical field conditions of no less than fifteen (15) years (lifetime estimate basis to be disclosed). It is required that data acquired from INL and ANL testing will be available for publication. Unacceptable technologies include: Lithium-ion, Lithium metal, Lead-acid, Redox flow batteries, any non-rechargeable system, any non-electrochemical system, any system requiring on-site fabrication, any system lacking sufficient durability in typical field conditions (<15 yr). SCOPE OF WORK These requirements define the minimum technical, safety, performance, and documentation expectations for acceptable long duration energy storage (LDES) systems. The system shall be capable of providing at least 10" hours” of continuous discharge at rated power and exporting both AC and DC power. Technology & Duration System must deliver ?10 hours at rated power under nominal conditions. Offeror must describe the non?lithium electrochemical technology, provide technical evidence (test data, certifications, field deployments), and outline any operational constraints. Provide dimensions, weight, expected lifetime, and fully burdened cost for module?scale and full?scale systems. Rated Power & Energy Modules: ?10 kW continuous power; ?100 kWh usable energy (10 hours). Bidirectional charging/discharging within stated environmental limits. Specify rated power/energy, overload capability, and electrical operating ranges. Full?Scale System: ?100 kW continuous power; ?1,000 kWh usable energy (10 hours). Bidirectional operation; same specification requirements as modules. AC/DC Interface & Controls AC interface: 3?phase, 60 Hz, 480 VAC; include single?line diagram and protection/connection requirements. DC interface: isolated export; 800–1500 VDC; specify current rating, transient behavior, grounding/isolation, converter needs. Preferred multi?port inverter providing simultaneous AC/DC power. Provide monitoring metrics, control interfaces, SCADA protocol support (Modbus TCP/IP, DNP3, IEC 61850), and Interface Control Document (ICD). Safety, Compliance & Hazard Mitigation Must meet NFPA 855, UL 9540/9540A (or equivalent), NEC/IEEE standards. Provide certifications or plan to obtain them. Submit hazard assessment (chemical, thermal, fire, explosion, environmental). Required safety systems: electrical protections, fire detection/notification, proper labeling/signage. Preferred: emergency stop, external alarm signaling/suppression. Include emergency response instructions. Performance, Availability & Degradation At…
