Workforce Development for the Future Grid – Energy Storage “Technicians”

The US Dept. of Labor projects that there will be an increase of about 14,000 jobs in employment of electrical power-line installers and repairers from 2014 to 2024. Growth will be largely due to the growing population and expansion of cities and upgrading the interstate power grid that will continue to grow in complexity to ensure reliability. Energy storage is not considered an occupational field by the DOL and the job description of Storage Battery Tester has not been updated since 2001. Global battery-making capacity is set to more than double by 2021, topping 278 GWh/year from the current 103 GWh/year. It has been reported that the creation of a 15 GWh/year plant could create 7,000 jobs during construction and require 300 full-time jobs after start up. The energy storage industry is growing rapidly, but the line workers and technicians of today do not possess the skill sets for these new jobs and as an aging workforce are unlikely to undertake the training required. In order to avoid a skilled labor shortage in the emerging energy storage field this workshop will define the skill sets needed for technicians, operators and maintenance personnel for the Future Grid and work on the curriculum needed to train them.

Control of Energy Storage Devices for Energy Management and Power Applications

With a quickly evolving electric power grid, new assets and algorithms will be crucial to maintain safe and reliable operation of the grid. Energy storage devices can be viewed as flexible, controllable assets capable of both enabling efficient energy management strategies as well as enhancing resiliency of electric power grid operation. In this tutorial session, we will provide an overview of classical control techniques and apply them to the control of energy storage devices, in particular, highlighting control approaches addressing both energy management and power applications. Several applications will be discussed including demand response and ancillary services, such as peak shaving, load shifting, and frequency regulation. Optimization plays a key role in effective and efficient use of energy storage devices, and we will introduce optimization-based approaches to the design of these automatic controls. Lastly, several key challenges and opportunities for advanced control of energy storage devices will be discussed.

Separator Materials for Electrochemical Energy Storage Systems

Electrochemical energy storage systems can be embodied in many forms, from Li-ion batteries to flow batteries, to alkaline batteries, or even molten sodium batteries. Despite their many varied forms, all of these systems contain an anode, a cathode, and a separator. As the name suggests, separators physically separate the anode and cathode from each other, preventing internal short circuiting, while enabling ionic transport. Depending on the energy storage system, the materials design requirements for the separator may drastically vary. For instance, Li-ion batteries typically use a porous separator to physically separate a solid anode and solid cathode, while for molten sodium batteries such a microporous separator would prove disastrous, leaking molten sodium. Understanding the advantages and limitations of various separator materials is important to successful design of electrochemical energy storage systems. This panel discussion will feature experts in different types of separator materials. Each panel member will provide a brief overview of one separator material and follow-on discussion will be centered around the advantages and disadvantages of each separator material, its target applications, and directions for future research.

Power Electronics in Energy Storage

Energy storage (ES) have been used for decades in electric transmission and distribution grid for energy management and power quality control. ES can be instrumental for emergency preparedness and provide multiple applications – energy management, backup power, load leveling, frequency regulation, voltage support, price arbitrage and grid stabilization. Power electronics (PE) plays a critical role in energy storage system design and integration by providing maximum energy transfer to and from the grid. PE enables the power source to connect to a specific load with a specific characteristic e.g. dc-ac (inverter), ac-dc (rectifier), dc-dc, ac-ac, change of voltage / current level, change of frequency etc. PE is naturally a cross-cutting technology that has a wide variety of applications. Significant advances have been made in semiconductor, magnetics, capacitors, controls, and packaging research and development (R&D) in the last several decades that provided new approaches to the conversion of energy. For example, wide band gap materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN) have made significant improvements over the last few decades. They offer the potential for higher switching frequencies, higher breakdown voltages, lower switching losses, and higher junction temperature compared to silicon-base semiconductors. The higher voltage and switching frequencies has a significant impact on PCS by allowing much smaller passive components like inductors and capacitors to be utilized for the same power requirement. Current energy storage systems utilize water cooled thermal management systems. By using higher junction temperature semiconductors, smaller cooling apparatus could be used resulting in significant increase in power density. Current energy storage systems are housed in shipping containers where high power density designs and more reliable PCS is critical. Advanced material that offer significant increases in power density, efficiency, controllability, and reliability is needed. The recent advances in advanced materials and packaging has improved the current PCS designs.

In this forum, each panel member will briefly discuss their technologies, applications and their perspectives on on-going R&D. The follow-on discussion will be centered around future power electronics R&D opportunities that will assist in making energy storage systems more viable technically and economically.
