Distributed Storage

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.

Aalborg CSP will connect a 2.5 MW ammonia heat pump to a district heating system operated by E.ON Denmark. The facility will be located at a local wastewater treatment plant.

Toshiba has developed a smart synchronous inverter that stabilizes power fluctuations in microgrids. The Japanese company said it has tested the device in combination with PV and battery storage.

US utility Xcel Energy will test the use of Ambri’s energy storage technology at the Solar Technology Acceleration Center.

Sharp is developing a zinc-air battery tech for renewables storage. The device will be reportedly safer than their lithium-ion counterparts, with high energy densities.

The company now offers a 25-year warranty for its panels and 10 years for its energy storage system.

Dutch manufacturer MG Energy Systems is offering a new storage system in two versions, with capacities of 5.8 kWh and 7.2 kWh and nominal capacities of 230 Ah and 280 Ah.

Australian researchers have developed a way to use rooftop PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

Italy added 303 MW/632 MWh of distributed energy storage capacity in the first half of 2022. The segment continues to grow in the country, with the regions of Lombardy and Veneto being the two largest contributors.
