AC vs. DC in residential buildings equipped with solar-plus-storage
Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.
India confirms focus on green hydrogen, solar and battery manufacturing
India’s 2023-24 budget shows the government’s plans to support the domestic production of lithium battery cells.
Only5mins! – Monetizing energy storage
Storage Hub founder Oliver Schmidt speaks with pv magazine about his outlook for battery energy storage pricing and the cost trajectory of electrolyzers. Schmidt’s new book, “Monetizing Energy Storage – A toolkit to assess future cost and value,” will be published by Oxford University Press in June.
EV batteries alone could satisfy short-term grid storage demand
Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and US researchers.
Swiss manufacturer unveils mini batteries for balcony solar panels
Soleis AG has developed two storage systems with capacities of 1 KWh and 2 kWh.
New lithium iron phosphate batteries for rooftop solar
V-Tac’s new 10 kWh lithium iron phosphate, wall-mounting battery system purportedly runs for more than 5,000 cycles.
Deploying solar, storage, heat pumps in the Arctic
US researchers have conducted case studies on the successful deployment of distributed renewables in the state of Alaska. In one study, two cities installed 223.5 kW solar PV arrays coupled with 351 kWh batteries and 250 kW inverters, in addition to cold climate heat pumps.
Retired coal sites to host multi-day iron-air batteries
Form Energy will install two 10 MW / 1,000 MWh batteries on the sites of Xcel Energy’s former coal-fired plants.
Second-life batteries might beat new ones on solar LCOE in remote locations
UK scientists have discovered that second-life batteries could provide a lower levelized cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.
Puerto Rico could approach 40% renewables by 2025
Rapidly deploying 5.2 GW of planned solar and storage in Puerto Rico, a possibility raised in a report by six national laboratories, would require an improvement in the Puerto Rico utility’s practices. A mandated procurement process has suffered delays at many steps.
