Eddy Chiang is Co-founder and CEO of Moment Energy, a company building commercial-scale energy storage systems from repurposed electric vehicle batteries. By testing, certifying, and remanufacturing second-life battery modules, Moment Energy is creating lower-cost alternatives to new lithium-ion storage while extending battery lifespans by decades.

In this episode of Inevitable, Chiang explains how a growing wave of retired EV batteries is reshaping the energy storage market—making recycling alone economically unviable. The conversation covers the technical and regulatory challenges of certifying second-life systems, how Moment Energy became the first company to achieve full UL certification, and why safety, not cost, is the real barrier to adoption.

We also explore how distributed battery systems can replace traditional grid upgrades, why hyperscaler demand is accelerating deployment, and how Moment Energy is positioning storage not just as a product, but as long-term infrastructure designed to last 100 years.

MCJ is a three-time investor in Moment Energy. The company just closed a $40M Series B co-led by Evok Innovations and the Canadian Growth Fund — with the participation of Amazon, Liberty Mutual, Voyager and our fund.
