World’s first high-power aluminum-ion battery system for energy storage
For the first time, a complete aluminum-graphite-dual-ion battery system has been built and tested, showing that lithium-free, high-power batteries can deliver stability, fast response, and recyclability for next-generation grid applications.
Brazil adopts legal framework for battery storage
Brazil published Law 15.296 on November 25, establishing a series of changes to laws in its electricity sector including guidelines for the regulation of storage systems, tax exemptions and the reduction of import tax rates on battery energy storage systems and its components to zero.
Keeping the smart grid cyber secure
As smart grid tech is rolled out around the world to modernize legacy assets and integrate renewable energy generation, it is also making the electricity network more prone to cyber attacks. IEC Standards provide protection but they also are challenged to keep up with the latest threats.
Global ESS shipments hit 286 GWh as Tesla and Chinese heavyweights out front

M-Tec launches modular propane heat pump for residential, commercial use
The new residential heat pump system can be configured modularly and requires less than 150 grams of refrigerant, which allows it to be installed indoors. The system integrates with M-Tec’s energy management platform and supports multiple heat sources, photovoltaics, and battery storage.
Cooling PV modules with seawater
A research team in India developed a passive solar-panel cooling method using a thin, still layer of seawater placed over the module surface. Tests showed that while a thick water layer sharply reduced energy output, a thin 5 mm layer lowered module temperatures and increased daily energy generation by up to 8.86%.
