Sandia provides energy storage technologies and integrated solutions for large-scale adaption of energy storage across the electricity infrastructure.

An Increasing Need for Energy Storage

To serve the needs of a 21st century consumer base, the U.S. power grid must adapt to the emerging challenges and opportunities facing the country. Continuing changes in both state energy generation assets and consumer demand characteristics necessitate the need for greater grid flexibility to maintain the reliability and affordability of the current infrastructure.

Energy storage provides an intelligent buffer between generation and demand that provides grid operators an essential tool for a reliable, resilient, and flexible power grid. While transmission provides energy where it is needed, energy storage provides energy when it is needed:

  • It ensures the resiliency of the grid infrastructure when severe disruptions occur, and can reduce economic losses from power outages while providing backup power and islanding capability during natural disasters.
  • By incorporating energy storage into their network, a utility can compensate for large-scale renewable generation variability through energy time-shifting to maintain network stability.
  • Wider scale integration of energy storage within today’s grid infrastructure can effectively improve the performance of the grid while reducing the cost of electricity to consumers.

Energy Storage and Grid Modernization

Sandia’s energy storage program addresses a range of topics in materials and systems as well as power electronics related to energy storage. Sandia researchers have addressed the high cost of membranes—a critical bottleneck in flow battery commercialization—by developing a new class of polymeric membranes with superior electrochemical properties and lower cost starting materials. Along with conducting extensive research in battery technologies, including lower temperature Na batteries and rechargeable alkaline batteries, Sandia has also developed lightweight nanocomposite materials for flywheels with increased rotational speeds.

Sandia is advancing power conversion systems (PCS) for grid-tied and off-grid applications. This is driven by the development of new semiconductor switching circuits, as they determine the overall cost, reliability, and performance of the converter. Next generation PCS use advanced semiconductor materials known as wide band gap semiconductors (i.e. Silicon Carbide and Gallium Nitride) that allow for faster switching frequencies, improved voltage breakdown characteristics, and higher operating temperatures. These high voltage switches, in conjunction with advances in ceramic capacitors, controls, magnetics, and packaging, lead significant improvements in system performance through increased power density and efficiency compared to PCS systems using silicon devices.

Sandia has a significant focus on safety and reliability of grid energy storage systems. This effort includes coordinating DOE Energy Storage Systems (ESS) Safety Working Groups which bring together over 150 stakeholders from industries that range from national laboratories, electric utilities, standards organizations, and manufacturing companies. The working groups are exploring gaps in safety R&D; enabling the development of codes, standards, and regulations (CSR); and educating first responders on storage system safety. Sandia also provides workshops and organizes technical conferences, including the Energy Storage Safety Forum which is slated to become an annual technical meeting for the world wide research community.

Sandia is the lead DOE lab in the development and implementation of energy storage demonstration projects and in performance analysis of energy storage systems in the field. Sandia works with the DOE in enabling energy storage systems deployment, and supports the U.S. Department of Defense, state energy offices, utilities, industry, and universities by providing design analysis, operational evaluation, and technology verification of energy storage systems. Sandia also has developing international collaborations with entities in the European Union, Japan, and Singapore. Sandia’s role in grid-tied field demonstration projects allows DOE and the nation to understand energy storage operation in grid applications, optimization of energy storage, system reliability, and the economic impact of energy storage in different market environments. Through the lab’s battery analysis program, Sandia assesses batteries ranging from the cell level to large utility class systems. Capabilities at the lab include reconfigurable command and control to simulate various use cases; analysis of advanced inverter functionality (up to 200kW); and grid simulation to measure changes in voltage, frequency, phase imbalance, and power quality.

Sandia supports research to enhance the regulatory environment for energy storage through a range of activities. These include estimating the value of energy storage for different applications and scenarios; developing control strategies that maximize revenue or benefit to the grid; identifying new control strategies and applications for energy storage; assessing public policy to identify and mitigate barriers for energy storage; developing standards; and evaluating projects.

Sandia collects key information on current and future storage technologies and acts as a clearinghouse for the information so that it can be effectively disseminated among key stakeholders and the community. Outreach activities include conducting strategic communication initiatives, managing the ESS website, improving the DOE Global Energy Storage Database, updating the DOE/EPRI Energy Storage Handbook, and organizing the Peer Review meeting and the Electrical Energy Storage Applications and Technologies Conference.

Sandia offers a network of interconnected laboratory facilities providing capabilities for real-world R&D for a variety of advanced grid technologies. The Energy Storage Systems Analysis Laboratory and its MW-scale Energy Storage Test Pad are user facilities enabling experimentation on battery cells, modules, and systems to improve performance, safety, and reliability. The Battery Abuse Testing Lab is a national center of excellence in energy storage system safety analysis. Research at this center includes studies on failure propagation phenomena, development of fire suppression methods to improve safety, and the development of high fidelity models. These facilities enable Sandia to partner with industry to remove barriers to for the large scale deployment of energy storage in the grid.
