This battery may solve renewables’ energy storage problem
Flow batteries are a type of liquid battery that has the potential for large-scale, long-term energy storage. Researchers have found a new material for flow batteries and it looks a lot like molasses.
Batteries of the future could be made from trees
To improve battery life and safety, while maintaining ionic conductivity, researchers aim to replace the liquids commonly used in batteries with a solid material made from trees.
How buildings can adapt to the seasons
Scientists have invented an all-season smart-roof covering that keeps homes warm in the winter and cool in the summer. It uses a phase-shifting material that doesn’t require additional electricity.
These supergrids are uniting the world’s clean energy supplies
Europe is creating a supergrid across regions, countries, and oceans to smooth out the fluctuations in energy suppliers — and hopefully build more resilient power systems.
There's a ton of wind power in the deep sea. Let's go get it.
The most powerful winds can be found over the deep, open ocean. Floating wind turbines could tap into this and 100x our wind energy.
NASA plans to put a nuclear reactor on the moon by 2031
NASA and the Department of Energy are asking U.S. companies for help putting a nuclear reactor on the moon by 2031.
Self-driving electric tractor startup to boost production eight-fold
California startup Monarch Tractor has raised $61 million to increase production of its self-driving electric tractor.
The science of climate change in 6 charts
Here's what the science says about climate change — and a few reasons to be optimistic.
Will battery recycling be ready when all these new EV batteries die?
The growing usage of lithium-ion batteries, particularly in vehicles, is outpacing the technology to recycle them. But researchers and innovators are scrambling to find an effective and eco-friendly battery recycling technique.
Metal-eating bacteria could clean up dirty mining sites
A unique metal-chomping microorganism ate through a nail in just three days. Now they might be tasked with an enormous mission: cleaning up mining waste.
