Researchers from Tokyo University of Science have shown that sodium ion batteries with hard carbon anodes can charge faster than lithium ion batteries by using a dilute electrode method that reveals that sodium insertion is intrinsically faster than lithium. December 19, 2025 Ev Foley Researchers from Tokyo University of Science (TUS) have found that sodium-ion batteries (SIB) using hard carbon anodes (HC) can charge faster than lithium-ion batteries (LIB), challenging long-held assumptions in battery research. The team sought to address the problem of conventional battery testing where the actual HC charging rate is often underestimated due to concentration overvoltage issues…
A new report A ReImagine Appalachia study released today shows that 67% of the region’s 92,282 projected clean energy jobs (more than 61,000 jobs) are now at risk due to dramatic policy changes under the Trump administration. “Tracking the Appalachian Impacts: What’s on the Line as Federal Funding Flatlines” documents how clean energy investments in Pennsylvania, Ohio, West Virginia and Kentucky have leveled off after historic growth. Carhartt x SunRun The analysis tracks quarterly data from 2018 through the third quarter of 2025, examining both federal and private investments in three categories: energy and industrial deployment, clean energy production, and…
The company deploys the first commercial tracking system with a 13-ft. free space hardened against wind and beef. December 19, 2025 Michael Puttré By pv magazine USA Oregon-based Rute SunTracker has commissioned its first commercial solar photovoltaic project designed for cattle ranches. The 120 kW solar panel is deployed on an Angus ranch in Jackson County Oregon and is connected to the Pacific Power grid. The project is another example of how agrivoltaic energy benefits both farmers and the solar energy sector. Agrivoltaics, the practice of integrating PV arrays with pollination, agriculture and pasture, is becoming a popular method for…
Renewable energy project developer EDF power solutions UK and Ireland has appointed METLEN Energy & Metals, headquartered in Greece, to complete the engineering, procurement and construction (EPC) works for its 400MW Longfield solar PV farm in Britain.METLEN will be required to carry out site surveys, purchase and supply of materials and all testing and commissioning work, with the exception of grid connection work. The company will begin construction in early 2027 and plans to complete work in 2030.With this award, METLEN has more than 95 projects in its portfolio of completed and under-construction solar and battery energy storage systems (BESS)…
Researchers in Slovakia have demonstrated a machine learning framework that predicts PV inverter output and detects anomalies using only electrical and temporal data, achieving 100% accuracy in classifying inverter output states under static operating conditions at a solar installation. December 19, 2025 Lior Kahana A research team led by scientists from Slovakia’s Constantine the Philosopher University in Nitra has developed a new predictive and anomaly detection model for PV inverters in commercial installations. The new machine learning-based framework uses only temporal and electrical data, without relying on environmental sensors. “The chosen algorithms, Random Forests for prediction and Z-score analysis for…
The House of Representatives has done that legislation passed that could revise permitting and environmental assessments for new energy projects. The Standardized Permitting and Expediting Economic Development (SPEED) Act was created to amend the National Environmental Policy Act of 1969, which established the practice of required environmental assessments for major projects. The legislation was approved in the House of Representatives and will go to the Senate for further consideration. The SPEED Act proposes to increase the number of project-related actions that do not require environmental review, set limits on the duration of reviews, and set review deadlines. The house reportedly…
Ahead of next year’s Solar Finance & Investment Europe event, hosted in London by Solar energy portal publisher Solar Media, speaker Guy Lavarack, chief investment officer at Luminous Energy Group, tells us about how the maturity of the UK solar and storage market has influenced the risk assessment for investors in the sector.“The UK market has matured, the technologies have matured and one of the biggest risks right now is around execution and just the capacity in the market to build,” says Lavarack.His comments come as part of a broader discussion on risk assessment and mitigation in the European solar…
