Sodium-ion battery technology firm Peak Energy has emerged from stealth, with US$10 million in funding and a management team comprising ex-Northvolt, Tesla, Enovix and SunPower executives.

The company announced its launch yesterday (4 October) following a US$10 million seed funding round led by venture capital (VC) firm Eclipse with participation from another VC firm, TDK Ventures.

Peak Energy will focus on the rapid scaling of sodium-ion battery manufacturing to address widespread demand for lithium-ion alternatives, it said.

Though US$10 million is not a significant amount for a manufacturing ramp-up, it is relatively large for a seed round. The median and average seed rounds in the US in Q1 2023 were US$2.3 million and US$3.7 million respectively, according to company intelligence provider Crunchbase.

“Sodium-ion is the key to unlocking the potential of renewable energy and will finally enable power providers to fully decarbonize the grid,” said Landon Mossburg, co-founder and CEO of Peak Energy.

“The timing could not be better to build a company in this space, and we already have momentum with key customers and partners like Doral Energy. There is a massive opportunity for the United States to emerge as the global leader in sodium-ion production and deployment, and Peak Energy is at the forefront of that effort.”

Sodium-ion technology is widely seen as the alternative battery storage technology to lithium-ion which is the furthest along the path to mass commercialisation. Commodity reporting price agency Fastmarkets recently wrote that it, along with solid state lithium-ion tech, are the two technologies offering the most potential to ease the pressure on conventional lithium-ion in a guest blog for Energy-Storage.news.

Electric vehicles (EVs) with sodium-ion batteries have been launched in China, but Peak Energy appears to be focusing primarily on the grid-scale stationary energy storage system (ESS) market.

It said the “high cost structure, supply chain insecurity, safety concerns and large carbon footprint make (lithium-ion) non-ideal for grid-level storage”.

The company has a target to lower energy storage costs by up to 50%.

Max Reid, research analyst in Wood Mackenzie’s Battery & Raw Materials Service segment, told Energy-Storage.news last year he estimated there would be around 1GWh of global annual sodium-ion battery production capacity in 2023 rising to 5-10GWh by 2025.
