Stanford Energy is brought to you by the Precourt Institute for Energy
By Mark Golden
Stanford University’s Precourt Institute for Energy, StorageX Initiative and Bits & Watts Initiative selected 17 new energy research projects on campus to fund.
Competitive selection was based on new, potentially transformative ideas for building a sustainable, affordable, secure energy future for the world. The $1.8 million will enable Stanford faculty, as well as five collaborators at other research institutions, to prove their concepts for high-risk, high-reward ideas through initial experiments and study. The research seeks to advance fundamental energy science, technologies, policies and business models.
The Precourt Institute has made such awards annually since 2010. Bits & Watts has done so since 2017. This is the first year of seed grants for the new StorageX Initiative, which is supporting eight teams. Precourt Institute and Bits & Watts funding starts Oct. 1, while StorageX funding began in May.
Preparing for rapid demand changes: Learning from COVID-19 and California wildfires
This team will ascertain how the current pandemic and wildfires have affected electricity use and the electric grid. They will assess different energy services and the overall level of electricity demand by residential, commercial and industrial consumers and estimate the consequences on emissions. The goal is to identify investment, operational changes, and the relevant policy required to prepare future grids for extreme events.

The researchers will study the mechanism by which these catalysts convert CO2 to enable the further design of these materials.
Organometallic electrochemistry: Energy-dense, low-cost, long-duration energy storage
The researchers plan to develop a new class of grid-scale flow batteries. The work is based on organometallic electrochemistry and has the potential to dramatically lower costs and increase energy density compared to current chemistries. These batteries use ultra-low cost active materials, have high energy density, can operate at ambient temperatures, and have a chemistry that can be tailored for safety.
Defining and managing oxygen-limitations of soils for negative CO2 emissions
This new team will investigate the effects of microsites, depleted of oxygen, on soil organic carbon. The researchers will employ and advance a process-based model that incorporates the contribution of these microsites to soil carbon storage and greenhouse gas evolution, inclusive of N2O, CH4, and CO2 emissions. The ultimate goal of this work is to define soil management recommendations to maximize negative CO2 emissions potential.
Environmental and economic impacts of China’s new CO2 emissions trading system
This project will develop a tool for quantifying the likely environmental and economic impacts of China’s new emissions trading system on the power sector. Environmental impacts will include changes in emissions of CO2 and local air pollutants. Economic impacts will cover changes in production levels, costs, net revenues, and consumer real income. These impacts will be assessed both for the nation as a whole and for individual provinces.
The potential for a U.S. transition to electrified medium and heavy-duty vehicles
Researchers will estimate monetized damages due to greenhouse gas emissions and criteria air pollutant emissions for medium- and heavy-duty vehicles over their life cycle under different degrees of electrification in the United States. Different types of policy mechanisms, incentives, and infrastructure investments needed to deploy electrified medium- and heavy-duty vehicles will be assessed. These analyses will be done in the context of current and future grid scenarios.

PI: Kenneth Goodson, Mechanical Engineering
This project will design and develop a passive heat pipe for aggressive thermal management of fast-charging cables and batteries for electric vehicles.

The proposed technology aims to reduce the weight of the cable and the energy overhead and the cost and design complexity of the charging station while improving overall reliability.
Second-life EV batteries: Predicting health using physics-informed machine learning methods
PI: Simona Onori, Energy Resources Engineering
This project seeks a new technology to assess the health of retired EV batteries, in terms of capacity, energy and impedance for re-use. Researchers will combine the strengths of electrothermal/aging models along with data driven methods to assess, without any historical data information from the device, the remaining life of the battery and optimize its deployment for secondary life.
Networked Battery Systems Lab: At the intersection of battery systems, IOT and the grid
This new lab will seek to improve collections of batteries in cars and buildings interconnected by the power grid and by communication networks. Closed and proprietary battery management, and simplistic operation models can hamper the ability to provide high value grid services and coordination. The lab will enable experimentation and exploration of new systems, management and testing in EV charging and grid storage applications.
Climate and health impacts from air pollution from battery production
This project uses an integrated assessment framework to study the monetized health, environmental and climate change effects of battery manufacturing and transport to the end use application for electricity and transportation applications globally. Researchers will include dependency on supply-chain, location of manufacturing and production, and local electricity grid characteristics in their assessment.
Design and analysis of a flexible solid-state electrolyte
PI: Christian Linder, Civil & Environmental Engineering
Current solid-state electrolytes cannot undergo large deformation due to their brittle nature. An intrinsically flexible solid-state electrolyte with high electrochemical performance is needed. The researchers will develop machine learning algorithms for the discovery of solid-state electrolyte materials with flexibility and high electrochemical performance. They will also study the performance and safety of the electrolyte under mechanical deformation.
Battery pack management system
PI: Simona Onori, Energy Resources Engineering
Efficient use of battery packs requires estimation and control algorithms that can account for the heterogeneities among cells, as well as the large thermal and aging dissimilarities that can be exacerbated, for example, under fast charging conditions. This research aims to model the complex explicit and implicit interactions between cells in a large battery pack through the use of electrochemistry, machine learning and experiments.

The electrode materials are designed to function in safe electrolytes to establish an easy, safe and cost-efficient recycling process.
Designing a circular lithium economy: Materials and processes for recovery from batteries
PI: William Tarpeh, Chemical Engineering
While lithium demand for batteries is rapidly increasing, surplus lithium discharges from battery production, storage, and disposal can pollute the environment. Because less than 1% of lithium is currently recycled from batteries, we reimagine lithium as a resource by designing novel membrane materials and electrochemical devices that selectively recover lithium from batteries.
