I can think of some real benefits.
The biggest problem with coal is that it is difficult modulate power as needed. In general power companies will run coal for baseline load 24 hours a day and cycle on and off more expensive NG turbines as the load changes. If there were a less expensive way to store electricity, the entire load could be generated with cheaper coal.
It would be a pretty good way to back up power in an industrial or commercial setting.
It may even be a good way to power a car too, who knows.
Seems like something with potential for standby/reserve power aps. Right now utilities with significant numbers of NUGs, (non-utility generators) have to keep a lot of capacity, (at considerable expense)on “spinning reserve” ready to meet demand surges and keep the grid stable. “Peaking” plants using gas turbines and NG fuel exist to quickly take up load surges. Some of these conditions might well offer practical application for this “goo”. I’m for anything that decentralizes and localizes our power sources. >PS
So far as yet gasoline seems to be the best fuel for an internal combustion, piston engine such as that in a car. It’s also lubricates the engine and other moving parts(people always concentrate on the rear of the car, never under the hood) Gasoline comes from oil and oil comes from the ground. And we’ve got lots of it. Oil is a demoracys most precious natural resource. It’s the black blood that makes possible all we produce and build and drive and fly to be the super power we are, to enjoy the standard of living we have— and to be free. It’s the reason the liberals and the ‘’greens( reds, really) are pushing this ‘’green revolution; green technology’’ bs. They hate American exceptionalism , they hate freedom.
