Lithium Batteries: The Disposal Problem

"Currently, lithium (Li) ion batteries are those typically used in EVs and the mega batteries used to store energy from renewables, and Li batteries are hard to recycle.

"One reason is that the most widely used methods of recycling more traditional batteries, like lead-acid batteries, don't work well with Li batteries. The latter are typically larger, heavier, more complex, and even dangerous if taken apart incorrectly."

Lithium batteries’ big unanswered question

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."

Geothermal Energy: A Little-Talked-About Alternative To Fossil Fuels

"There is a lot of energy right under our feet, a relic from Earth's hot past as a ball of plasma. But how much can geothermal energy realistically do for us? What technologies are currently being pursued, what are the risks, and is it even carbon neutral? In this video, we have collected all the relevant facts and numbers for you."
