The wind and sun are both free and almost infinite, and therefore each extra unit of energy generated is not only clean but also essentially free. With little downside to using more electricity when it is available, we?ll need to rethink energy efficiency.
A new EU regulation aims to shrink the environmental footprint of biofuels starting in 2021. But scientists think we should go one step further and take into account all compounds produced at biorefineries, not just biofuel.
Researchers report the results of experimental and computational investigations on the conversion of lignocellulosic biomass into a bio-based chemical called acrylonitrile, the key precursor to manufacturing carbon fiber.
Water could form the basis for future particularly inexpensive rechargeable batteries. Researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one step closer to using the technology commercially.
