As power systems evolve to accommodate rising levels of renewable energy, traditional grid-following converters (GFLs) are no longer sufficient to ensure grid stability. Researchers from Imperial College London and Tsinghua University, led by Dr. Fei Teng and Mr. Guoxuan Cui, conduct a comprehensive techno-economic analysis of how to determine the optimal penetration of grid-forming converters (GFMs) required for future power networks. Their findings highlight how coordinated planning and dynamic operational control strategies can enable cost-effective and stable operation of “new-type power systems”.
Karlsruhe Institute of Technology (KIT) and the Joint Research Centre (JRC) of the European Commission intend to work together even more closely in the areas of nuclear safety and security as well as nuclear safety monitoring. They want to make an effective contribution to understanding and solving scientific issues – both in fundamental research and in other nuclear applications such as medical research. To this end, the two institutions have signed a new cooperation agreement. The public will benefit from the results.
Chemists from the National University of Singapore (NUS) have synthesised a new class of carbon nanostructures: fully π-conjugated, pentagon-embedded non-alternant carbon nanobelts (CNBs). This achievement addresses a long-standing challenge in molecular design and opens avenues for next-generation organic semiconductors and quantum materials.
A research team at Japan’s National Institutes for Quantum Science and Technology (QST) has demonstrated that electron beam (EB) irradiation can decompose polytetrafluoroethylene (PTFE) — a highly durable plastic known as Teflon — into gaseous components. This method drastically improves the energy efficiency compared to conventional recycling processes, offering a promising path toward reducing the environmental impact from per- and polyfluoroalkyl substances (PFAS).
