Solar energy to drive Indonesia’s transition away from coal, biofuels
The role of solar PV in Indonesia will extend beyond replacing coal-based electricity generation; it will also include the production of e-fuels for hard-to-abate segments, offering an alternative to land-intensive biofuel production. A recent study explores, through various scenarios, the cost-competitiveness of solar PV-based electrification in supporting Indonesia’s renewable energy transition.
Wireless EV charging based on PV, three-port DC–DC converter
Scientists have developed a wireless charging system for electric vehicles, with a three-port DC–DC converter at its core. They have simulated the system and tested a prototype in their lab and have found it achieved an improved efficiency of 88%.
What’s behind the aging mechanism of sodium-ion batteries
Researchers in China have used electrochemical impedance spectroscopy to analyze the state of health of sodium-ion batteries. Extracting four features from the measurements, they were able to create a machine learning model for a temperature-resistant state of health estimation method.
Worldwide battery storage installations up 54% in first half of 2025, June sets monthly record
New data from Rho Motion shows that over half of June’s installations were concentrated in China, maintaining the country’s dominance in the global energy storage market.
Photovoltaics for cargo ships
Wattlab has installed a PV system capable of delivering up to 35 kW to a cargo ship’s high-voltage propulsion system, allowing it to temporarily replace one of four diesel generators under optimal conditions.
Upcycling solar glass waste to use in solid-state lithium batteries
Nanyang Technological University researchers have milled solar panel glass waste for use in cathodes used in solid state lithium metal batteries. When used as a functional filler in solid polymer electrolyte (SPE) material, the resulting battery performance was maintained over 80 charge cycles with an 8.3 % improvement over the reference device.
