Jamaica seeks proposals for 100 MW of renewables
The Jamaican government is seeking 100 MW of renewables to diversify its energy grid, with independent power producers to generate this capacity through wind, solar, and hydro projects recommended under power purchase agreements (PPAs), according to tender documents.
Cyprus starts first nanogrid project
The University of Cyprus and energy developer Ecotricity Holdings have jointly installed a nanogrid system for a single building in Cyprus. The aim is to minimize the site’s energy consumption costs and eliminate the power system’s carbon footprint.
How long do residential solar batteries last?
Multiple factors affect the lifespan of residential battery energy storage systems. We look at the lifespans of batteries in the third part of this series.
Single-reagent tech to reuse silicon from end-of-life PV panels achieves recovery rate of 98.9%
Scientists in Singapore developed a single-reagent approach to recover silicon in recycled PV panels that reportedly offers high recovery rates compared to double-reagent methods. The recycled silicon was then effectively reused in anodes intended for applications in lithium-ion batteries.
Three steps to reduce battery storage fire risk
Lithium-ion batteries are generally safe and unlikely to fail, but they can catch fire if damaged, stored, or operated incorrectly. With calls mounting for development of engineering good practice, US-based Firetrace International suggests three steps that battery manufacturers, developers and operators should take into account.
Stryten Energy vanadium redox flow battery on path to commercialization
Stryten Energy is planning to begin commercializing its vanadium redox flow batteries in January 2025. Meanwhile it has deployed a 20 kW/120 kWh pilot-sized version of the storage system at a facility operated by Snapping Shoals EMC, an electricity cooperative in Georgia, United States.
Italy adds 1,468 MW/2,058 MWh of distributed storage capacity in H1
Italy hit 3,045 MW/4,893 MWh of distributed storage capacity in the six months to the end of June. The segment continues to grow, led by the regions of Lombardy and Veneto.
Tesla launches Powerwall 3 battery
Tesla has launched the Powerwall 3 battery with an energy capacity of 13.5 kWh and continuous on-grid power of 11.5 kW, featuring dimensions of 110 cm x 61 cm x 19.3 cm and a weight of 130 kg.
Shell looking to sell Sonnen
Shell, which acquired Sonnen four years ago, is now actively seeking a majority shareholder for the Germany storage system specialist.
EnerVenue launches new metal-hydrogen battery variant
EnerVenue has developed a new metal-hydrogen battery. The US startup says the battery’s efficiency ranges from 80% to 90%, depending on the cycle rate, and claims that its energy density per square foot is equal to or even better than lithium-ion batteries.
