DEC’s “Dongchu No. 1” prototype completed more than 100 charge-discharge cycles at 65 meters depth in a freshwater lake.

Rising silver prices are pushing PV manufacturers toward copper-based metallization, with DK Electronic Materials targeting 2026 for large-scale deployment of high-copper paste solutions, while Fraunhofer ISE warns efficiency trade-offs remain unacceptable.

Iola Hughes, Head of Research at Benchmark Mineral Intelligence, tells ESS News that 2026 is set to be another strong year for BESS, with forecast additions exceeding 450 GWh and no material supply constraints in sight. Meanwhile, the initial impact of rising lithium prices is already visible at the cell level, but the full effect has yet to ripple through to system pricing.

WFES 2026 in Abu Dhabi underscored growing momentum for solar, storage, and C&I renewables across MENA, with batteries emerging as a key enabler for grid stability, agriculture, and data centers. Industry leaders pointed to Iraq, Libya, Yemen, and Saudi Arabia as key growth markets, highlighting rising interest in AI-driven data centers, solar-plus-storage solutions, and a broadening regional supply chain.

Four agencies told 16 leading firms to rein in irrational competition as China tightens oversight of power and storage batteries.

China’s PV manufacturing sector is operating at full capacity ahead of an April 1 export tax change, contributing to module price increases of 20% to 30% in parts of the supply chain and raising risks for price-sensitive European commercial and utility-scale projects in early 2026.

With lithium prices reaching a two-year high in early 2026, sodium-ion batteries are once again in the spotlight, as innovators on both sides of the Atlantic announce major milestones.

SoftBank Group is piloting AI-controlled cellular base stations powered by solar panels and a 3 kW wind turbine to reduce energy use while maintaining service quality. The system stores excess power in batteries and can automatically switch to the grid when needed.

UNSW researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.

Axinar has launched SolBox, a direct PV water heating system that powers electric resistance accumulators without thermal collectors. It’s designed for homes and businesses, offering real-time monitoring, MPPT optimization, and automatic grid backup.
