Could utilities’ costly battery storage plans provide backup electricity — and savings?

The Connecticut Post

The New York Power Authority is using batteries designed by Cadenza Innovation, which has offices in Wilton and Danbury and a test lab in Oxford. Cadenza CEO Christina Lampe-Onnerud co-chairs the World Economic Forum’s Global Future Council on Energy Technologies.

5 Lessons From the Battery Fire Investigations


It’s been over a year since the McMicken battery facility in Surprise, Arizona began to smoke and eventually exploded. We’ve learned a lot since then. I spent the last several weeks digging through a series of investigations, tracing what happened, why safety systems failed, how designs should change and what approaches can better protect firefighters. (You can read those analyses here, here and here.)

Result from UL testing ‘proves’ innovative battery platform can stop thermal runaway propagation

Energy Storage News

Cadenza, founded by Onnerud in 2012, has developed a battery architecture and manufacturing platform that aims to cost-effectively eliminate one of the biggest issues facing the grid storage industry today. As seen in fires at energy storage system (ESS) facilities in South Korea, China and in Arizona, one cell catching fire can cause enormous damage as fire propagation causes it to cascade from cell to cell. The company announced yesterday that its battery cells have been proven to stop propagation when thermal runaway is induced, having earned UL9540A certification. Under that testing, battery cells are “artificially” made to burn.

8 Steps Towards a Sustainable Economic Recovery

World Economic Forum

There has been much discussion over the past few years about the ‘energy transition’. The underlying premise is that the transition to lower and zero-carbon energy sources should be accelerated to mitigate the impact of global warming. The current pandemic is shining additional light on global inter-connectivity and the need to collaborate and share best practices.
