A report by the International Energy Agency (IEA) recommends three strategies to accelerate the deployment of distributed solar and battery energy storage systems (BESS) in Ukraine as the country works to increase its energy security.

Kanazawa University has begun long-term outdoor testing of tandem perovskite solar cells in collaboration with Toshiba. The research project aligns with Japan’s broader push to scale perovskite PV technologies toward large deployment by 2040.

Researchers in Italy have simulated an agrivoltaic-powered anaerobic digestion plant for biomethane production and optimized it across eight scenarios, using vertically mounted panels in some cases with one-axis tracker and with two-axis trackers in others.

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.

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.

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.
