Energy Storage as a Transmission and Dual-Use Asset

thursday, December 1, 2022  | 11:00 a.m. (PDT) to noon

Featuring: Jeremy twitchell, senior energy analyst

The Federal Energy Regulatory Commission (FERC) issued a policy statement in 2017 supporting the deployment of energy storage for the dual uses of regulated transmission service and competitive market service. By allowing this usage model, FERC reasoned, revenue earned through market operations when the storage asset isn’t needed for transmission could be shared with customers and system costs could be reduced. But this approach represents a significant change in electric grid operations, which historically have separated transmission and generation functions into distinct siloes, and efforts by regional market operators to implement the policy statement have been, so far, unsuccessful. In this presentation, we will discuss a recent Pacific Northwest National Laboratory report that identifies a participation framework for dual-use energy storage assets.

Two men shoulder to shoulder
Featuring: Witness martin and yangang liang, materials scientists

The ability of data-driven materials research to provide useful tools for scientific discovery and optimization has been demonstrated. However, the application of a data-driven research method to complex materials systems has specific hurdles, such as a lack of large-scale and high-quality data sets, appropriate algorithms, and the development of accurate/reliable prediction models. In this talk, we will highlight the development of high-throughput experimentation (HTE) capabilities under Pacific Northwest National Laboratory’s Energy Storage Materials Initiative to accelerate the data-driven energy materials approach. We will specifically discuss how we developed an HTE process for collecting large-scale and high-quality solubility data of redox active materials in redox-flow-battery-related media, as well as how we used our robotic platform to accelerate the discovery of non-flammable electrolyte recipes for lithium-ion battery electrochemical systems.

Featuring: Qian Huang, Materials scientist 

Battery degradation/reliability, which is directly related to its lifetime and safety performance, depends not only on chemistry, but also on complex physical-chemical processes under diverse operating conditions. Motivated by PNNL's reliability investigation on lithium-ion batteries (LIBs) for stationary application, this presentation will shed light on the mechanism of LIB degradation using a calorimetric approach. In particular, a methodology for in-situ heat measurement of commercial LIBs under grid services is being developed in order to disclose the relationship between thermal characteristics and the degradation/reliability of LIBs and to reinforce the development of the LIB state-of-health model.

This presentation provides a cost-benefit analysis of four grid services: 1) arbitrage, 2) demand-charge reduction, 3) spinning reserve, and 4) frequency regulation, when using fleet vehicle-to-grid (V2G) battery power. V2G technologies enable the bi-directional flow of energy between electric vehicles (EVs) and the grid. An aggregation of battery-stored electricity from EVs, such as those found in a fleet, could deliver a substantial amount of energy and act as a potential grid resource.
