Energy Storage
When I first came across the click-bait garbage at left, I was reminded of an earlier post I wrote on the subject of the history of this form of energy storage. Various countries in Europe began using the potential energy …

Pumped Hydro Soon to Go Into Its Second Century
These people claim: An American startup just unlocked hydropower from dry land — with no rivers or dams. In a radical rethinking of water-based energy, an American startup has developed a closed-loop hydropower system that works without a natural river …

“Gravity Batteries”
Below is a claim about a type of energy storage that exists in great abundance today in the form of pumped hydro. We take off-peak electrical energy and use it to lift a mass against the force of gravity, converting …
Flywheels as Energy Storage
The subject of energy storage is like anything else in technology: lots of entrants of completely different types that, over time are winnowed down, and ultimately, the “winners win and the losers lose.” What happens next is that the losers …
