US startup unveils plug-and-play solid-state battery for residential applications
Zendure has developed a residential storage system using a semi-solid state battery with 6.438 kWh capacity. Each unit is scalable with up to four batteries, bring the capacity of one unit to 32 kWh and of two units to 64 kWh. The system can be used with solar panels.
Hydrogen bromide flow battery for large-scale renewables storage
Dutch startup Elestor has secured funds to bring its hydrogen bromide (HBr) flow battery technology closer to commercial production. It said the system could achieve a levelized cost of storage below $0.05/kW.
Solar-driven multigeneration system for hydrogen, electricity, heat
An Iranian research group has developed a system that combines photovoltaic-thermal modules with organic Rankine cycle, a proton exchange membrane electrolyzer, and liquefied natural gas. The ideal system has an exergy efficiency of 16.24%, a cost rate of $4.48 per hour, and 33.32 kW of net electrical power.
Yingli unveils n-type TOPCon solar panel with 22.0% efficiency

The Hydrogen Stream: Globeleq to build solar-powered 3.6 GW green hydrogen plant in Egypt
Egypt’s hydrogen strategy is taking shape ahead of COP27 through agreements with Globeleq, Actis, and Alfanar. Elsewhere in the world, the US authorities are investing in blue hydrogen, and the city of Hamburg, Germany, has signed three agreements with Chile, Uruguay and Buenos Aires.
Micro hydropower system for building applications, usable with solar
Japanese startup Yumes Frontier has developed a 2.7 kW micro-hydropower system that can be used in some buildings. It can also be combined with solar to provide power for lights and surveillance cameras.
Lab-made perovskite solar panel loses 25% of efficiency over 9-month period
Researchers have studied a perovskite solar panel array with little generation loss due to high temperatures, and better performance than expected.
Solar on US canals moves closer to reality
Project Nexus expects to break ground on a canal-top solar project in the fall, with completion targeted by the end of 2023.
Aluminum-sulfur battery for small-scale storage at $8.99/kWh
Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.
