The device developed by researchers at the TU Bergakademie Freiberg uses aluminum as an anode, graphite as a cathode and a polymer-based solid electrolyte. It is validated and further developed for industrial production. The goal is a storage capacity of 10 kWh. September 12, 2024 Petra Hannen The first prototype will consist of a 10-cell ‘stack’ and will be able to store approximately 1 Wh of electricityImage: Image: TU Bergakademie Freiberg/A. Hieke By ESS newsTU Bergakademie Freiberg University of Technology has reported significant progress in developing an aluminum battery, which is based on materials that are both readily available and…
Most Chinese PV manufacturers’ half-yearly margin reports are in the red, with losses of 30%-50%. Image: Jinko Solar. Finlay Colville, head of research at Solar Power Portal’s sister website PV Tech, has predicted that the current PV production downturn affecting the sector will continue into 2026. The pressing question for 2025, Colville writes in a blog post on PV Tech, will be when we see the first signs that the downturn is ending. Colville says the worst is yet to come before the improvements begin. As such, 2025 will be “humbling” for the sector, he said, with the current downturn…
The ratification of the Wormald Green BESS (photo) makes the HEIT portfolio 100% operational. Image: HEIT. Harmony Energy Income Trust (HEIT) today (September 12) announced that it has powered two major UK battery energy storage systems (BESS). Investment company BESS has successfully powered its Hawthorn Pit and Wormald Green projects, with both expected to become fully operational in the coming weeks. The 49.9MW/99.8MWh Hawthorn Pit project is located in County Durham, while the 33MW/66MWh Wormald Green project is in Yorkshire. Both projects use two-hour liquid-cooled energy storage systems supplied by Envision Energy, with this endorsement marking Envision Energy’s first working…
Italy’s Ministry of Environment and Energy Security (MASE) says it has received 643 bids for a total of 1.7 GW in its first agrivoltaic tender. About 56% of proposals come from the sunny southern regions of the country. September 12, 2024 Massimiliano Tripodo By pv magazine ItalyItalian MASE has announced the results of its first agrivoltaic tender. The ministry received subsidy applications for 643 projects, totaling 1.7 GW.Subsidizing these projects would require a total investment of approximately €920 million ($1.01 billion). MASE said most proposals came from Italy’s sunny southern regions.The auction is open to projects of any size from…
The system is the first Eku Energy project to go live in the UK. Image: Eku Energy. Energy storage specialist Eku Energy has announced the successful commissioning of its Maldon battery energy storage system (BESS), the first UK project to become commercially operational. The Maldon BESS project, located in Essex, just outside London, has a capacity of 40 MW/40 MWh. The project was built by Trina Storage, which will service and maintain the project throughout its operational life. In addition, the project has successfully secured a long-term capacity market contract traded by EDF. “The Maldon battery energy storage system is…
The Belgian transmission and distribution system operator says it plans to connect solar panels and batteries to the grid for households with a plug and socket from May 2025. September 12, 2024 Patrick JowettSynergrid, the federation of Belgian transmission and distribution system operators for electricity and gas, will soon allow solar panels and household batteries with a plug and socket to be used on the country’s electricity distribution networks. The measure applies to mobile plug-and-play solar panels and batteries that function as standard household appliances and can be purchased from well-known retailers.Synergrid is adapting C10/11, a legally binding rule in…
Norwegian developer Scatec ASA has signed a 25-year power purchase agreement (PPA) for a 1 GW solar array and 100 MW/200 MWh battery storage project in Egypt. CEO Terje Pilskog says this is the first hybrid solar-plus-battery project in Egypt. September 12, 2024 Patrick Jowett Norway’s Scatec has signed a 25-year PPA with Egyptian Electricity Transmission Co. (EETC) for a hybrid project of 1 GW solar energy and 100 MW/200 MWh battery storage in Egypt.“This will be the first hybrid solar and battery project in Egypt,” said Terje Pilskog, CEO of Scatec. “We will now finalize the leasehold agreements, grid…
CAB Solar has released a new above-ground cable management system, ModulAir. The free-air solution meets NEC requirements for utility-scale solar projects and has been tested to certify that the cables can be run to their designed current limit without exceeding temperature ratings. CAB Solar’s ModulAir Hanger system uses a layered cable separation system, optimizing airflow around cables to improve eBOS performance and eliminate the need for cable reduction. The suspension system can be combined with the company’s patented overhead cable management system with integrated grounding. “With ModulAir, CAB Solar customers will enjoy the benefits of maximizing the capacity potential of…
In a paper published in Nature, the Chinese module maker explained that the 33.9% efficient tandem device it unveiled in December 2023 is based on a double-layer, interleaved passivation strategy that combines efficient electron extraction with further suppression of non-radiative recombination. It also revealed that its two-terminal tandem prototypes achieved an efficiency of 34.6%. September 12, 2024 Vincent Shaw and Emiliano BelliniChinese solar module manufacturer Longi has revealed that it has achieved an energy conversion efficiency of 34.6% in prototype dual-terminal tandem perovskite solar cells.“Currently, the two-terminal tandem prototypes developed by Longi’s tandem team have been authoritatively certified with a…
