Supercapacitor technology is the golden key for making low energy density sources like wind/solar/tidal cost effective.
“low energy density” = low density energy
mea culpa
Not so fast.
Another needed key to wind/solar/tidal is approval to build high voltage power lines where they don't exist. Not likely soon.
Super capacitor’s power storage is measured in microwatt hours. Leveling the powergrid will require hundreds of megawatt hours. There is, however, some interesting research into liquid batteries where battery reactants can be pumped in and out of the cells in units measured by tons.
Pardon my pessimism, I have followed Eestor for years.
That being said, I would love to charge my phone in seconds.
That, and it’d be a way to make electric cars viable. For with a supercapacitor, the car can be ‘refueled’ in less time than it’d take to refill your gas tank.
Which would then allow for long-distance travel.
