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 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.

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.

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.

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%.

The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its facility in Munich. The system uses an AI-based energy management system that reportedly makes battery storage unnecessary.

 The U.S. based manufacturer has completed certification of its latest adhesive-free, fluorine-free backsheet.

An international team of researchers completed a preliminary techno-economic study on the global potential for offshore floating PV (OFPV). The results provide project cost benchmarking, country-specific economic assumptions, and a global assessement of offshore solar’s levelized cost of electricity (LCOE).

The two-terminal perovskite–silicon tandem solar cell was fabricated through a chemical polishing method that selectively removes residual lead(II)iodide from the perorvskite film in the top cell. This targeted interfacial engineering improved uniformity and stability, enabling a certified 31.71% efficiency and enhanced long-term performance.

Omniflow has developed a line of hybrid solar-wind streetlights. It offers optional solutions to integrate for security, phone recharging, and Internet of Things applications.
