Startup begins producing 40%-efficient thermophotovoltaic cells
Antora Energy says its new 2 MW factory will make thermophotovoltaic cells for thermal storage applications. The cells are based on III-V semiconductors and reportedly have a heat-to-electricity conversion efficiency of more than 40%.
Startup unveils saltwater flow battery for large-scale storage
U.S.-based Salgenx has developed a scalable redox flow battery with two separate tanks of electrolytes, one of which is saltwater. Unlike other flow batteries, the new device is membrane-free, promising big gains at the levelized cost of storage level.
New method to measure energy yield of bifacial PV systems
Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.
Upswing in PJM interconnection costs amid energy transition, report says
Huge growth in interconnection requests along with lengthy reviews and high project withdrawal rates motivated PJM to create a “first-ready, first-served” approach in 2022, Berkeley Lab notes.
