MyGrid’s new 1.5 kWh lithium iron phosphate battery system purportedly runs for more than 6,000 cycles. It uses a bidirectional charger to receive and send electricity to the grid via a wall socket.

Madagascar-based Filatex has invested €10 million in French flywheel storage system manufacturer Energiestro. The two companies are planning to deploy Energiestro’s flywheel storage solutions across Madagascar and Mauritius

Researchers in Italy are combining PV with latent heat thermal storage (LHTM) and other renewable energy sources to maximize clean energy consumption in buildings. The 47kW PV array and LHTM system work independently, but the scientists said that a heat pump could be used to link them.

At Intersolar North America in California, Canada-based Discover Battery has launched the Helios energy storage system, an LFP battery designed to operate in remote conditions.

The campus of the Delft University of Technology (TU Delft) in the Netherlands is currently hosting a retrofitted existing building provided with heating by an H₂ heating boiler in the attic. The boiler is linked to an underground hydrogen system.

The device was designed by scientists in Portugal to optimize light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm² photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

Panasonic said the system is available in the U.S. with storage capacities of 17.1 kWh and 25.65 kWh. The product comes with a floor-standing battery cabinet and a hybrid smart inverter with 4 MPPTs.

The Chinese manufacturer says the battery has a depth of discharge of 95%. It will be available for sale starting from Q1 2022.

The US battery manufacturer entered the stationary storage business with a new product for residential customers. The lithium iron phosphate (LFP) battery is compatible with new or existing PV systems.
