Solar Philippines says it has broken ground on what it touted to be the world’s largest solar array – a 4 GW solar park spread across 3,500 hectares of land in the northern part of the country.

Third-party tests of GDI’s 100% silicon anodes show that they offer more than 30% energy density than graphite anodes, allowing for 15-minute rapid charging up to 80% state of charge (SOC) for hundreds of times back to back.

An international research group has developed a PV-driven liquid air energy storage (LAES) system for building applications. Simulations suggest that it could meet 89.72% of power demand, 51.96% of heating demand, and 11% of cooling demand in a PV-powered building.

Researchers in Japan have taken advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the performance of so-called “quantum batteries.” They believe these advances could help to bring the technology a little closer to reality.

Researchers from Australia have created a model to optimize the interaction between vehicle-to-home (V2H) systems and residential PV connected to battery storage. They claim V2H can help reduce the cost of energy by 16.7% for workplace charging and 25% for public charging.

Almost 2 GW of solar was tendered in the latest UK Department for Energy Security and Net Zero auction, while almost 500 MW was recently awarded in the latest auction round spearheaded by Irish power transmission operator EirGrid. But these gains come with five challenges, according to analysts from New Zealand-based consultancy firm PSC.

Brazilian conglomerate Intelbras says its new storage solution consists of one or more batteries that can be connected in parallel, with up to 10 units. It reportedly has a useful lifespan of more than eight years.

Three-month solar panel permit wait times, rooftop installations and projects under 50 kW not requiring environmental impact assessments, and a raft of other emergency measures aimed at accelerating the European Union’s (EU) renewable energy rollout have been extended until mid-2024 to combat the energy crisis.

Ark Energy’s 275 MW/2,200 MWh lithium-iron phosphate battery, to be built in the Australian state of New South Wales, has been announced as one of the successful projects in the third tender conducted under the state government’s Electricity Infrastructure Roadmap.

Saudi Arabia-based energy developer ACWA Power says it has signed a power purchase agreement (PPA) with state-owned utility Eskom for a 442 MW solar facility with 1200 MWh of battery storage in South Africa’s Northern Cape province.
