« This phenomenon occurs because extremely thin layers of liquid brine exist within the solid ice, between individual ice grains. Bending the ice creates a pressure gradient, causing the brine to flow toward areas of lower pressure. Since the salty liquid contains positively charged particles called cations, the streaming fluid generates an electric current. »

So..maybe a self powered hand crank ice cream maker?? That would be cool. 😉
I’m pretty sure you could get more energy just by using the low temperature of salt-melted ice mixture as the cold side of a Stirling engine
Edit: correction – this is energy harvesting rather than storage the way my suggestion would be. It seems much more interesting as a natural phenomenon to study than a useful thing to build
do the ice shelves on the artic seas generate a bunch of electricity then?
Could we power a water desalination machine with frozen salt water?
