Sulphur hexafluoride (SF6) plays an important role as an insulating gas in electrical switchgear at various voltage levels when interrupting and diverting current flows. At the same time, it is one of the most effective greenhouse gases with a very long lifetime and, although the concentration of SF6 in the atmosphere is currently still very low, it accumulates steadily over the years. The Fraunhofer Institute for Energy Economics and Energy System Technology IEE in Kassel and the Grenoble Ecole de Management (GEM) are performing a research study to investigate the environmental and socio-economic impact of the usage of the gas sulfur hexafluoride (SF6) in power distribution grids.
The study will analyze the use of the potent greenhouse gas SF6 and of F-gas free alternatives in medium voltage grids. The study is intended to support the COP 21 Paris Agreement, and industry’s sustainability commitments towards the nature and the planet.
The study focuses on medium voltage (MV) switchgear of electricity grids in the European Union.
Power grid stakeholders who have strong interest in MV power equipment and sustainability are invited to join this research study. Initial members are Siemens and Schneider Electric.
Study participants might contribute with their specific knowledge and will have preferential access to the results. They can choose from three membership options with different rights and financial contributions:
Full Members, Participating Members and Study Supporters. Applications for membership are open until 31 May 2019.
The research started in March 2019. The definition phase will close mid-June. Results will be available early 2020. The final results will be presented in a publicly available white paper.

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.
Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...
An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...
