A Possible Solution To The Energy Storage Problem?

"As we look to transition to our electric future, researchers are still stumped about how to store the electricity generated by inconsistent renewable power sources like solar and wind. Now, scientists report progress in storing energy by shifting the shapes of molecules, a solution that could be directly combined with photovoltaics. This idea makes a lot of sense — at least to me. Let’s take a look."

Gravity Batteries: Another Approach To Clean Energy?

"Could a cutting-edge technology that harnesses one of the universe's fundamental forces help solve our energy storage challenge?

There is a riddle at the heart of the renewable energy revolution. When the wind blows, the sun shines, and the waves roll, there is abundant green power to be generated. But when skies darken and conditions are calm, what do we do?

The answer, today, is to ramp up conventional power production, supplying the grid by burning fossil fuels. It is a 20th Century solution to a 21st Century problem – one that sits in sharp contrast with plans for carbon neutrality.

A cleaner future will mean focusing on ever-larger lithium-ion batteries, some energy experts say. Others argue that green hydrogen is the world's best hope. And then there are those placing their bets not on chemistry, but the limitless force that surrounds us all: gravity.

"Underpinned by Newton's immutable logic – what goes up, must come down – this new field of energy storage technology is, in principle, remarkably simple. When green energy is plentiful, use it to haul a colossal weight to a predetermined height. When renewables are limited, release the load, powering a generator with the downward gravitational pull."
