Navien unveils residential air-source heat pump
The South Korean heating specialist said its new heat pump can achieve a seasonal coefficient of performance of up to 4.87 and flow temperatures of up to 75 C.
U.S. researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation
A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
Photovoltaics for cold climate data centers
A Japanese-Finnish research group has assessed the levelized cost of energy of solar power plants supplying electricity to data centers in cold climates and has found that PV electricity could be considerably cheaper than grid electricity, even if used with battery storage.
World’s first anode-free sodium solid-state battery
Researchers in the U.S. have created a new sodium battery architecture with stable cycling for several hundred cycles, which could serve as a future direction to enable low-cost, high-energy-density and fast-charging batteries.
The Hydrogen Stream: Hydrogen power plants feasible but inefficient, says CATF
The Clean Air Task Force (CATF) says in a new report that dedicated clean hydrogen production and use is often a costly, inefficient decarbonization strategy for the power sector, while American Airlines says it has signed a deal with ZeroAvia for 100 hydrogen-electric engines.
GoodWe eyes potential of Europe’s C&I storage market
Ron Shen, vice president of power electronics manufacturer GoodWe, recently spoke to pv magazine at The smarter E Europe event in Munich, Germany, about the company’s position in the European market and its focus on the fast-growing commercial and industrial (C&I) storage segment.
