Oscal releases 2 kWh battery for home, off-grid, on-grid use
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.
How to balance power losses, cost effectiveness in PV-BESS-driven EV charging stations
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.
Panasonic launches new air-cooled heat pumps
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.
Paraguay set to host autonomous solar-powered data center
Sollar Machine plans to build a $9 million off-grid data center in Paraguay powered entirely by solar and batteries to deliver high-performance computing services for international clients, with a focus on AI.
Cash flow analysis shows adiabatic compressed air storage is viable for 10–100 h applications
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.
Hydro approves largest pumped hydro project in more than 20 years in Norway
Norsk Hydro will invest about $110 million after tax to build the Illvatn pumped hydro plant in western Norway.
Sodium-ion battery storage for ultra-low temperatures
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.
A late but decisive move to ESS: LONGi takes majority control of PotisEdge
China’s largest solar manufacturer seeks to escape shrinking margins by securing 62% voting control of a fast-rising storage integrator.
Reducing PV module temperature with twisted tape
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%.
In Puerto Rico, residential solar and storage growth outpaces utility-scale developments
Puerto Rico has reached 1.3 GW of residential solar and 185,000 residential batteries, with Wood Mackenzie expecting three more GWh of residential storage by 2029. Utility-scale solar and storage projects are gearing up, as described by an attorney with McConnell Valdés.
