“Optimal Energy Storage Siting and Sizing: A WECC Case Study”

The large-scale integration of grid-scale energy storage and the increasing penetration of renewable resources motivate the development of techniques for determining the optimal ratings and locations of storage devices. Electrical engineering professor Daniel Kirschen and students propose a method for identifying the sites where energy storage systems should be located to perform spatio-temporal energy arbitrage most effectively and the optimal size of these systems.

“‘Smart’ Engineered Fluids for Ultra-Low-Cost Manufactured Electronic Devices & Solar Cells”

When an Intel computer chip or conventional silicon solar cell is manufactured, materials with different functions are placed next to each other in carefully controlled, and often repeating, patterns at the nano- and micro-scale. But, achieving this nano-to-micro-scale manufacturing requires complicated and expensive machines. Getting nature to put different (heterogeneous) materials together spontaneously into repeating patterns, a process called self-assembly, could help. Professor Lilo Pozzo (chemical engineering) has laid out a process called "heteroassembly" to do just that. Starting with an "ink," a fluid containing nanomaterials with engineered interfaces, Pozzo, CEI Graduate Fellow Ryan Kastilani, and Ryan Wong (Bellevue Community College; now University of Minnesota) show that they can get a mixture of two types of nano-particles, each about 1/1000th the diameter of a hair, to pair and then spontaneously grow in a specific patterned way to form linear heteroassemblies. The key is how Kastilani engineered the particle interfaces to efficiently stick to, or be repelled from, the other kind of particle in the mixture. This is an important step in turning an ink from a "dumb" fluid we use to color a piece of paper, to a "smart" engineered fluid that becomes the foundation for ultra-low-cost manufactured electronic devices and solar cells.

“Optimal operation of a battery energy storage system: Trade-off between grid economics and storage health”

The utilization of grid-scale energy storage is growing exponentially due its decreasing costs and added flexibility to providing numerous services. Among the currently available storage systems, batteries based on lithium-ion chemistries are poised to provide a significant share of such flexibility due to their high power and energy density, and relatively low cost per unit energy. However, research on such systems has been segregated into focus on its chemical properties, and focus on the grid integration separately. This paper from Schwartz (chemical engineering), affiliate assistant professor Miguel Ortega-Vazquez (electrical engineering), CEI Graduate Fellow Matt Murbach (chemical engineering), and Mushfiqur R. Sarker (Argonne National Laboratory), proposes a data-driven framework to characterize battery energy storage systems embedded into a decision-making optimization model.
K-12 Outreach
9th Graders Use Blackberries to Activate Solar Cells
In August, CEI hosted ninth graders from Chief Sealth International High School completing a Seattle MESA summer program. Education Director Shaun Taylor and Clean Energy Ambassadors helped students build dye-sensitized solar cells activated by wild blackberries. Students also toured the Molecular Analysis Facility and learned how CEI researchers use the Atomic Force Microscope to understand how to improve devices like the ones the students made.

CEI Helps Teachers Introduce Engineering Design
In July, Taylor showed K-12 teachers from Pierce, Snohomish, and King counties how to introduce engineering design to students using aluminum air batteries at the Puget Sound Renewable Educator Leadership Institute sponsored by the Bonneville Environmental Foundation and the Boeing Foundation. The teachers are developing lesson plans based on what they learned at the Institute and will post them on the Solar 4R Schools site.
Government Relations

WA Lt. Governor, UW Vice Provost for Research, & CEI Solidify Partnership with Tsinghua University in Sichuan Province
Earlier this month, Washington Lt. Governor Cyrus Habib, UW Vice Provost for Research Mary Lidstrom, CEI Director Dan Schwartz, CEI member faculty, and UW spinouts Battery Informatics and Membrion traveled to Chengdu, the capitol of Sichuan Province, China to meet with officials from Tsinghua University’s Energy Internet Research Institute (EIRI) and provincial leaders. CEI and EIRI signed a collaboration agreement and EIRI pledged two seed fund projects, one on low emission transportation led by civil and environmental engineering professor Yinhai Wang, and the other for research led by professors Jim Pfaendtner (chemical engineering) and professor Daniel Kirschen (electrical engineering) on multi-scale engineering of clean energy systems. This work is part of the “2+2 MOU” that Washington, Sichuan Province, UW, and Tsinghua University signed in 2015 to support collaborative research on clean energy and sustainable cities.
