Top 10 Sodium-Ion Battery Projects: 4.75 GWh Jupiter Power deal, 30 GWh BYD factory plan (2024-2025)
Sodium-ion (Na-ion) batteries are rapidly transitioning from research to commercial-scale deployment, primarily targeting the stationary energy storage sector as a credible and cost-effective alternative to lithium-ion. This shift is substantiated by multi-gigawatt-hour supply agreements, such as the landmark 4.75 GWh deal between Peak Energy and Jupiter Power, and massive manufacturing commitments including BYD’s planned 30 GWh factory. The dominant market theme for 2025 is the established bankability of Na-ion technology, proven by the first grid-scale deployments in the U.S. and Europe and the successful operation of 100+ MWh systems in China, which solidifies its role in diversifying global energy storage supply chains.

BESS Applications, Sodium-Ion’s 30-40% Cost Edge
The recent wave of deployments reveals a clear strategic focus: sodium-ion is being positioned as the workhorse for stationary energy storage, not as a direct competitor to high-performance lithium-ion in every segment. Its lower energy density is a manageable trade-off for a significant 30-40% production cost advantage over Lithium Iron Phosphate (LFP) chemistry. This economic benefit is paramount for applications like utility-scale BESS and long-duration energy storage (LDES), where capital expenditure is a primary driver. Projects like the 200 MWh China Southern Power Grid facility and Great Power’s 100 MWh LDES initiative demonstrate that developers are prioritizing Na-ion’s lower cost, enhanced safety, and supply chain stability for grid-scale applications where spatial footprint is a secondary concern.
LFP Li-ion Battery Cost Reduction Forecast
The section’s claim of a ’30-40% cost edge’ is best understood relative to its main competitor, LFP lithium-ion. This chart shows the cost trajectory of LFP, providing the necessary benchmark to validate and contextualize sodium-ion’s cost advantage in BESS applications.

China Leads with 30 GWh BYD Sodium-Ion Factory
Geographically, China is establishing a commanding lead in both the deployment and manufacturing of sodium-ion technology. The commissioning of the world’s largest Na-ion project by China Southern Power Grid and the commercial operation of EVE Energy’s system underscore the nation’s ability to rapidly scale and execute. Furthermore, the plan for a 30 GWh annual production base by BYD signals an intent to dominate the global supply chain. In contrast, the U.S. and Europe are making important but smaller-scale advances. The first U.S. grid-scale installation by Peak Energy in October 2025 is a critical commercial milestone, while Tiamat Energy’s planned 5 GWh factory in France represents a key effort to build a regional European manufacturing base. However, the high-profile shutdown of Natron Energy in the U.S. serves as a stark reminder of the immense capital and market challenges Western companies face in competing with state-supported Chinese giants.
Sodium-Ion Battery Market to Hit $2B by 2030
This near-term market forecast quantifies the commercial opportunity that China and BYD are aggressively targeting. The 30 GWh factory represents a major step toward capturing a significant share of this emerging multi-billion dollar market.

Sodium-Ion’s 10 MWh Projects Signal Commercial Readiness
The installation data from 2024-2025 confirms that sodium-ion technology has crossed the threshold from pilot to commercial-ready. The operation of systems at the 10 MWh scale, such as the initial phase of the Vulin project, provides the bankable, real-world performance data required by developers and financiers. The technology is now mature enough to secure multi-gigawatt-hour supply agreements, exemplified by the Peak Energy and Jupiter Power deal, which shifts the conversation from technical feasibility to supply chain execution. The emergence of hybrid BESS projects in China, pairing Na-ion for bulk energy with Li-ion for fast response, indicates a sophisticated understanding of how to leverage the technology’s strengths within a complex grid services market. This demonstrates a level of maturity where different battery chemistries are chosen for specific roles rather than a “one-size-fits-all” approach.
Sodium-Ion Battery Market to Reach $12B by 2035
This chart illustrates the long-term potential being unlocked by the initial commercial projects mentioned in the section. It shows that today’s 10 MWh-scale successes are paving the way for a market projected to be worth over $12 billion, signaling a major technological shift.

4.75 GWh Peak Energy Deal, A Sodium-Ion Supply Chain Test
For 2025 and beyond, the most critical development to watch is the execution of large-scale manufacturing and deployment outside of China, which will determine if sodium-ion can establish a resilient, geographically diverse supply chain.
- If the 4.75 GWh Peak Energy supply agreement with Jupiter Power proceeds on schedule, watch for similar multi-GWh offtake agreements from other U.S. and European independent power producers.
- This could mean that Western developers are gaining confidence in the technology’s bankability and performance, de-risking it for project financing.
- If Tiamat’s 5 GWh French factory and other European initiatives successfully ramp up, watch for a reduction in reliance on Chinese cell imports for regional projects.
- This could mean the start of a bifurcated market with regional pricing and supply dynamics, influenced by local policy incentives.
- Conversely, if there are further setbacks like the Natron Energy shutdown, watch for a consolidation of market power among major Chinese players like BYD and CATL.
- This could mean that despite the technology’s promise, the West may struggle to build a competitive manufacturing base, repeating the dependencies seen in the lithium-ion market.
Sodium Abundance and Research Surge Fuel Market
This chart explains the fundamental reason why a massive 4.75 GWh deal is even possible. The abundance of sodium as a raw material, unlike lithium, is what allows the supply chain to scale and meet such large-scale demand, making this deal a true test of its capabilities.
