Chinese Academy of Sciences developing thermoacoustic heat pump for industrial applications
The researchers developed a heat-driven thermoacoustic heat pump that can purportedly achieve a temperature lift of 125 C. It uses a thermoacoustic heat pump to stably release the heat from the engine unit. The system also includes a thermoacoustic engine unit and acoustic resonators.
Enphase introduces 97.5%-efficient microinverter based on gallium nitride tech
The inverter is designed for three-phase grid configurations without using external transformers. It contains gallium nitride technology, a first for Enphase’s microinverters.
California now hosting canal top solar-plus-storage plant
California has completed the 1.6 MW Nexus canal-top solar pilot, adding a 75 kW iron-flow battery system as part of a $20 million state-funded project to test water and energy benefits.
Midea launches air-to-air heat pump for high latitudes
Conceived for Nordic conditions, the Raynor heat pump features a seasonal coefficient of performance of 5.1 and a cooling seasonal energy efficiency rating of 9.2.
Colombia to replace subsidies with solar for 1 million low-income households
Colombia will equip more than 1 million low-income households with solar systems to replace subsidies, cut bills and add capacity to the grid.
Dow releases new silicone gel for high voltage PV
The company said that its Dowsil EG-4175 Silicone Gel resists temperatures of up to 180 C in next-generation IGBT modules used in inverters.
Hydrogen can mitigate curtailment in floating PV-pumped hydro energy storage systems
Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.
France’s Sunology introduces modular residential battery
The system plugs into either a standard power outlet or the main electrical panel and automatically captures surplus solar energy – whether generated by rooftop panels or a portable plug‑and‑play kit. Up to four modules, each with a capacity of 2,200 Wh and 500 W of output, can be combined, and the system comes with a 7,500-cycle warranty for long-term reliability.
S&P Global unveils 2025 Tier 1 module, inverter, battery supplier list
S&P Global’s first 2025 Tier 1 Cleantech Companies list ranks 63 solar, wind, inverter, and battery suppliers by technology, financial health, and sustainability to guide investors and developers.
Marstek Energy throws down a price gauntlet with new balcony battery
