Sandia-Developed Precision High Power Battery Tester Earns R&D 100 Award

Posted: 01-23-17

R&D Magazine has recognized Sandia National Laboratories researchers’ work in developing innovative battery testing with the annual R&D 100 Award.

As principle investigator of the Precision High Power Battery Tester, Dr. Summer Ferreira was presented with the R&D 100 Green Tech Special Recognition Award.

The PHPBT uses high-precision charge/discharge test measurements at up to 200A current to capture electrochemical measurements such as coulombic efficiency with greater accuracy than was previously possible at currents applicable to EV and stationary storage applications. The goal is to detect minute signs of battery degradation earlier than previous testing, providing insight into a battery’s long-term capabilities and enabling engineers to better select feasible technologies from those needing more development.

With support from the Dept. of Energy’s Office of Electricity (DOE OE) and ARPA-e, PHPBT research was done in conjunction with Arbin Instruments, Ford Motor Company, and Montana Tech. Arbin has since commercialized the PHPBT technology.

R&D Magazine presents the annual R&D 100 awards to honor the year’s 100-most innovative technologies as selected by an independent panel of more than 70 judges.

The Dept. of Energy’s Office of Electricity Delivery and Energy Reliability Energy Storage Program has announced their release of the Energy Storage Safety Strategic Plan (PDF, 685 kb) to standardize the validation of the safety of grid-scale electrical energy storage projects.

The Strategic Plan addresses the key area of validated energy storage safety, spanning grid-scale, utility, communal, and residential deployments for the increasing array of energy storage technologies. It highlights the key areas of validation techniques, incident preparedness, and safety documentation, and recommends near- and long-term actions to address these needs.

Dr. Imre Gyuk, director of DOE OE and Energy Reliability Energy Storage Program, says, “We want energy storage to reach full acceptance as a component of the electric grid. For this to happen, a number of things must occur: technical feasibility of our technologies, competitive costs and established value, a regulatory framework, and safety. If we don’t have validated safety, we don’t have a product.”

NV Energy Electricity Storage Valuation Study Released

Posted: 06-28-13

Sandia National Laboratories’ Electric Power Systems Research Dept. and Pacific Northwest National Laboratory’s Advanced Power and Energy Systems Group have released a jointly authored report that examines how grid-level electricity storage might benefit the operations of NV Energy in 2020, and assesses whether those benefits justify the cost of the storage system.

Titled “NV Energy Electricity Storage Valuation” (PDF, 933 kb), the report finds that grid-level storage adds the most value to the 2020 NV Energy system by providing regulating reserve, and that a grid-level storage facility in the 2020 NV Energy system may have a positive net present value at today’s storage system prices, provided that regulating reserve from a fast ramp rate resource is valued more than that from a slow ramp rate resource.
