Researchers from the Tokyo University of Science have shown that the use of copper defects in sodium manganic oxide can eliminate battery types, which stimulates the lifespan of the battery cycle. July 17, 2025 Tristan Rayner Image: Shinichi Komaba, Tokyo University of Science By ESS News Researchers from the Tokyo University of Science have discovered that adding copper to a sodium ion battery cathodermaterial improves stability and therefore the lifespan. The study, published in Advanced materialsDemonstrates a method to overcome an important defect in β-natrium manganic oxide (β-namno2), a promising cheap alternative for lithium-based materials. The NAMN material exists in…

Slovenia has opened a call of € 29 million ($ 33.7 million) under the Modernization Fund of the European Union to support priority solar and wind projects, with applications for January 7, 2026. July 16, 2025 Patrick Jowett SloveniaThe Ministry of Environment, Climate and Energy has one investment call co-financing of solar and wind energy projects that have granted priority status. A total of € 29.5 million is available via the Modernization Fund of the European Union. Eligible projects can apply for a subsidy for a maximum of 45% of the project costs. If the Energy Storage Capacities project includes,…

China fights the export of curbs on some battery technologies China has tightened the export restrictions on certain technologies for battery materials on Tuesday, while Beijing extends in the emerging sector in spite of his trade war with the United States. The two economic super powers have traded this year due to export parties, whereby Washington in particular increases the threshold for selling high-end semiconductors to China. The government of US President Donald Trump has also accused Beijing of obstructing the export of rare earths in retribution against major rates that it has imposed on Chinese goods. The Ministry Van…

HR1 changes most solar-related tax credits of the inflation reduction law, but cuts on solar energy are the most abrupt. The Act terminates the 30% homeowner-collected investment tax credit (25d) for Solar + storage installations on the roof at the end of 2025. Residential solar -itc changes in HR1 Requires installations to be completed before December 31, 2025, to receive 30% ITC Will end the residential solar and independent storage ITC after 31 December without phase-down Projects do not necessarily have to be interconnected with the grid before December 31 to collect the credit Unused residential ITC credits can be…

ThyssenKrupp Nucera reports a decrease of more than 20% in the sale of the third quarter, with narrowing losses in green hydrogen and decreasing profit in the chlorine-alkali-segment. July 16, 2025 Sergio Matalucci ThyssenKrupp Nucera The sale of the electrolysis technologies fell by more than 20%in the third quarter of the tax year 2024-25. Alkalic water electrolysis (AWE) fell 23% to € 103 million ($ 119.6 million), while the chlorine-alkali (CA) segment fell by 21% to € 81 million. Based on provisional, non -GEAUDITED figures, the electrolysis specialist said It expects the consolidated income before interest and taxes (EBIT) of…

Developers who started the process report problems ranging from a bad user interface to being unable to upload evidence documents. Image: National Grid. From 2 p.m. (BST) Today (July 16) Neso has confirmed an extension of the deadline for five working days network connection applications. In a live webinar in which the window extension announced, Matt Magill, director of Engineering & customer solutions Transformation at Neso, said that there are currently more than 900 application depots in the system, with just over 200 entered submissions. His most important message, prior to tackling the emphasized problems, was “please do”. Neso is…

Flexible connections, better optimization and then for better cooperation between parties for grid connections were all hot topics in the German-oriented second session of the event. July 16, 2025 Marian Willuhn Image: Marian Willuhn, PV Magazine By ESS News Flexible connecting agreements are part of the process and should not be considered a nuisance by project developers. That sentiment summarized the German Deep-Dive session: “Flexible access, stable income-grid connection solutions for Bess”, on the Battery Business & Development Forum 2025 in Frankfurt am Main, Germany. Although many projects in Germany are confronted with years of delays due to bottlenecks, some…

Researchers in China have used electrochemical impedance spectroscopy to analyze the health status of sodium batteries. By extracting four characteristics from the measurements, they were able to make a machine learning model for a temperature-resistant status of health estimation method. July 16, 2025 Lior Kahana A research team of scientists from Chinese Chongqing University and the State Grid Corporation of China has experimentally investigated the aging mechanism of sodium batteries (SIBs). With the help of the results of this study, the group was able to develop an estimation method of the temperature -resistant condition (SOH) with an average average absolute…

Energie -Secretary Ed Miliband (depicted) states that the reforms “developers will provide certainty”. Image: Lauren Hurley / Desnz. The British government has a series of rule changes Greenlit for the upcoming allocation Round 7 (AR7) auction round for the Contracts for Difference (CFD) scheme. A consultation on proposed rule changes ran between February and March of this year. Feedback made the latest changes to the CFD scheme prior to the auction round, which will start later this year. CFD contracts of two decades will stimulate “the attractiveness of the attractive” for investors One of the most important changes is the…
