Episode 33 – Power Firming and Peak Shifting to Better Energy Delivery
September 30, 2011
In Episode 33 of The Wendel Forum(originally aired on Green 960 AM radio on September 24, 2011), show host Dick Lyons welcomes Peter Walters, COO of Zinc Air Inc. and an expert on the topic of how to deliver utility-scale energy (particularly from renewable sources) more efficiently. Peter provides explanations regarding the concepts of power firming and peak shifting, along with a number of other aspects related to safe and predictable energy delivery.
His company, which is based in Kalispell, Montana, is the developer of the Zinc Redox flow battery. According to the company’s website:
Zinc chemistry reduces cost through the use of abundant and locally available materials. Zinc Redox batteries have high energy density, low cost, safe operation, and are designed to be the greenest battery technology on the market. Using a flow battery technology, Zinc Redox focuses on grid storage applications including energy peak shifting and renewables (solar/wind) integration, designed to address the issues of matching demand with supply and variability.
Peter identifies several of the problems we face in the U.S. related to our delivery of energy to consumers. According to him, we waste about 60% of the energy we produce, we have an aging energy infrastructure, and demand continues to increase. Not only that, but new applications (such as electric vehicles) are placing new stresses on our energy delivery systems.
Current generation and transmission of energy throughout the grid fail to adequately address the issues of real time supply and demand. Historically, we have struggled to effectively store energy so that it can be harnessed and released to the grid when needed. The development of better battery storage technologies opens the possibility of load shifting and other tactics to deliver energy when supply is required, not just when we are able to produce it.
During his interview, Peter explains some of the limits of our current infrastructure and how battery storage may solve many of the problems. He and Dick also discuss some of the specific challenges as they relate to the production of energy from renewable sources, such as solar and wind.
Need more proof that this technology is heading in the right direction? The flow battery solutions being developed by Zinc Air start with safety. The chemicals used are non-toxic and not corrosive, a step forward from what we typically think of in batteries. The company spends a lot of time on the issue of safety in the product development and the installation of these systems, addressing concerns related to both man-made and natural disasters. And they know they have to do this all at the right price point.
This Saturday (October 1, 2011) tune in to The Wendel Forum at 11:30 a.m. on Green 960 AM radio for a conversation with Flory Wilson of B Labs, who will reveal the new Global Impact Investing Ratings System (GIIRS), which is a comprehensive and transparent system for assessing the social and environmental impact of companies and funds with a ratings and analytics approach analogous to Morningstar investment rankings and Capital IQ financial analytics.
