Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.

SunWiz market data ranks the manufacturer as the top energy storage supplier in Australia, Ireland, and South Africa.

Researchers have studied the potential of combining photovoltaic systems with compressed air energy storage (CAES) to power a commercial building in South Africa. They found that a co-optimized system could lower total capital costs by 15–20% compared to traditional sequential sizing approaches.

Jackery continues to expand its product range beyond storage with a new 2 kW solar gazebo designed for creating outdoor space, starting with US availability in 2026.

Space-based solar could power AI more efficiently than on Earth, with full-scale deployment possible in two to three years, Elon Musk said last week in Davos, Switzerland. SpaceX’s Starship launch vehicle and its reusable rockets aim to sharply reduce space access costs, enabling solar-powered AI satellites and potentially large-scale extraterrestrial energy infrastructure.

The U.S. Department of Energy moved to de-obligate or revise billions in financing for clean energy projects while prioritizing natural gas and nuclear power.

This week Women in Solar+ Europe gives voice to Melodie de l’Epine, Senior Project Manager/ Head of Research & Innovation at France’s Becquerel Institute. She says that ncouraging men to shift from strict hierarchy to informal exchanges fosters more equitable rapport. Women can benefit from noticing how men address each other and consciously joining in, since subtle forms of address strongly shape power perceptions.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.

Austrian engineering group Andritz has signed a deal to supply the pump turbine units for a 500 MW pumped storage plant in South Korea, the country’s first new pumped storage project in over a decade.
