Sodium-ion BESS startup Moonwatt expects the battery chemistry to reach price cost parity with lithium iron phosphate (LFP) in the next two or three years, according to its CCO, Valentin Rota.
Speaking to us at the Smarter E Europe trade show in Munich, Germany, this week, Rota said: “We think LFP will stay a great chemistry for high-density front-of-the-meter (FTM) systems, while we think for our solar hybridisation applications, sodium-ion is a great fit.”
“And when we look at what’s to come on the roadmap we see further cost decreases for sodium-ion. We think probably within the next two to three years we should have a cost parity reached, which also means that in absolute levelised cost of storage (LCOS) terms, sodium-ion will be significantly more competitive than LFP.”
That is because sodium-ion (Na-ion) has a higher cycle life than lithium-ion, lithium iron phosphate (LFP) battery cells, reducing the cost per cycle, which forms part of the LCOS calculation.

Moonwatt has developed a modular, 200kW BESS unit for DC and AC-coupling hybridisation with solar PV, designed to reduce installation and engineering, procurement and construction (EPC) costs to the bare minimum. Its first project is in the Netherlands, on which it announced completion this week during the trade show.
Rota discussed its technology and deployment plans, which we will cover in a full write-up and video interview article in the coming days.
Sodium-ion was a big talking point at the clean energy trade show and conference this week, following major announcements like lithium- ion OEM CATL and system integrator Hyperstrong’s 60GWh deal in April.
CATL launched its latest 30MWh+ Na-ion solution and talked about the tech in detail during a media Q&A, which Energy-Storage.news attended. We also sat down with system integrator HyperStrong’s head of technology to hear its perspective and deployment roadmap for sodium-ion. Keep your eyes peeled for the full write-ups of both of those too!
This article was updated after publication to change ‘LCOS’ to ‘cost’ in the headline.
