Scientists in China have developed an optimized energy management strategy for a wind-PV hybrid heat pump system that uses both thermal and electric energy storage. Using different seasonal interaction management strategies, they simulated four operational cases.

Scientists in Ghana have developed a device that combines a conventional solar PV-powered steam cooker with sand-based thermal energy storage. The system can achieve a thermal efficiency of 38.9% and has a payback period of 4.5 years.

The Chinese company said its 2,016 Wh portable LiFePO₄ energy-storage system is expandable to 22,176 Wh with additional battery modules. It delivers 2,400 W output, offers 16 ports, app-based control, and includes built-in audio and lighting features for home, travel, and off-grid use.

Scientists in India have developed a novel method to optimize the placement of an EV charging station on the grid, along with the size of its PV generation and battery storage. They have also created a framework for an innovative slot offering.

The heating and cooling business of the Japanese giant has released a new range of heat pumps for commercial projects. The systems have capacities of 40 kW and 50 kW.

Scientists in the United Kingdom have compiled a new database of adiabatic compressed air energy storage projects. Using this data, they were able to determine the experience rate and identify the conditions under which the technology would be economically viable. According to their findings, costs have declined at a 15% learning rate since 2013.

U.S. researchers have developed a sodium-ion pouch cell that operates reliably at temperatures as low as –100 C. The battery was tested with simulated and real renewable energy sources, including wind and solar, and maintained stable performance in both laboratory and field conditions.

Researchers in Iran have investigated how twisted tape in water-cooled channels can enhance heat transfer in solar modules. They have used a computer simulation to analyze the new approach with different parameters and have found the panels’ ectrical efficiency increased by up to 11.84%.

The US mounting system provider said its new product is designed to fit both Cee and Zee purlin-framed structures. It features a bottom-oriented setscrew.

A team of researchers in Canada has developed the Jericho Open Resistive Data Logger—an open-access photovoltaic (PV) monitoring platform that integrates data acquisition and processing hardware, a software framework, and a comprehensive sensor array. Designed primarily for agrivoltaic applications, the system has a total estimated cost of around $2,000.
