Off-grid lessons help drive new battery tech
Battery manufacturer Vaulta is using lessons learned from Australia’s growing off-grid energy sector to spearhead the development of its next-generation battery energy storage technology.
Sun-tracking photovoltaics for stadiums
Researchers in Italy have developed a sun-tracking PV system design for stadium covers. The proposed approach is said to offer both strong structural response and high energy yield compared to systems based on fixed structures.
Power Roll developing 12.8%-efficient back-contact perovskite solar devices
Researchers from the U.K.’s University of Sheffield and Power Roll, a perovskite solar PV technology company, have achieved 12.8% power conversion efficiency in indium-free devices based on novel back-contact process. A slot-die coating process was demonstrated, compatible with roll-to-roll manufacturing.
Hamworthy presents new air-source heat pump series

UbiQD developing novel encapsulant technology for solar modules
The U.S.-based quantum dot (QD) materials company is developing polymer encapsulation materials that reportedly have the potential to provide a relative power boost of 16% when integrated into crystalline silicon PV devices.
Utrecht wastewater plant launches largest heat pump in Netherlands
Innomotics, Eneco, and Johnson Controls have energized a large-scale heat pump at a municipal wastewater treatment plant in Utrecht, the Netherlands. The system has four heat exchangers, each equipped with two compressors.
The impact of wind load effects on offshore floating photovoltaics
Researchers have investigated the aerodynamic performance of a single floating PV setup of 16 panels, as well as an array that combined 15 such setups. They found that drag coefficient distributions and wind pressure effects on PV systems vary by inlet angle. They have also identified cost-saving opportunities through material optimization.
