In a new Perspective article, researchers are aiming to tackle a fundamental debate in key reactions behind fuel cells and hydrogen production, which, if solved, could significantly bolster clean energy technologies.
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.
