Grid-scale battery storage is crucial to the success of the transition to renewable energy. Wind and solar are marvelous technologies, but their output tends to vary depending on wind speeds, cloud cover, and other factors. Until recently, grid-scale storage batteries have relied on lithium-ion batteries — NMC to begin with, but LFP more recently. Peak Energy believes it has the ability to manufacture sodium-ion batteries that outperform both at half the cost.
On its website, Peak Energy says it is “the first American venture to advance globally proven sodium-ion battery systems as the storage standard for the new era of renewable energy on a resilient grid.” This week, the company emerged from stealth mode to announce a $10 million funding round led by Eclipse, with significant…
