Satellite navigation company TomTom reported that 387 cities across the world experienced a decrease in congestion. Similarly, a decrease in public transport usage was seen as governments across...

New financial analysis tool for long-duration energy storage in deeply decarbonized grids

New financial analysis tool for long-duration energy storage in deeply decarbonized grids

Graphical abstract. Credit: DOI: 10.1016/j.joule.2021.06.018 Renewable energy generation technologies such as solar, wind, and hydro continue to gain popularity worldwide. As more and more renewable generation enters the grid, the success of these clean technologies will increasingly rely on the development of long-duration energy storage solutions that support variability in...

3D optical memory devices using fluorescent materials would significantly cut global electricity consumption

3D optical memory devices using fluorescent materials would significantly cut global electricity consumption

Credit: Pixabay/CC0 Public Domain There's always room for another bright idea when it comes to safely storing the colossal amounts of electronic information we produce every day. Researchers at Te Herenga Waka—Victoria University of Wellington are investigating whether fluorescence can be used to store three-dimensional (3D) data.Initial findings show 3D...
