What Energy Storage Buyers Need to Know Heading Into 2027
Large loads like data centers are now contracting directly with construction firms to build storage systems, bypassing traditional developers. This shift creates significant risk for buyers who lack in-house expertise in quality assurance, sourcing, and financing standards.
Italy: Sodium-ion narrows the gap with lithium-ion, says Polytechnic University of Turin professor
Silvia Bodoardo from the Polytechnic University of Turin notes that state-of-the-art sodium-ion cells have reached 175 Wh/kg with high capacity retention at extreme temperatures. This technological convergence is significant for energy storage professionals as it positions sodium-ion as a viable alternative for utility-scale applications where cost and safety are prioritized over maximum energy density.
How Far Can BESS Continue to Contribute in Chile? Coordinator Warns of Potential Saturation
The National Electric Coordinator warns that Chile's battery storage system may reach saturation as 5,130 MW of new capacity comes online. This shift forces operators to diversify revenue streams beyond energy arbitrage to maintain grid stability and asset viability.
Sodium-ion batteries gain ground as a lithium alternative thanks to supply chain diversification and cold-weather performance
Wood Mackenzie reports that sodium-ion battery supply agreements have exceeded 70 GWh, signaling a shift toward commercial production. This development is critical for energy storage professionals as it highlights the technology's potential to diversify supply chains and offer cost-competitive alternatives to lithium-ion systems in specific markets.
