Please leave the feedback on this challenge
Is the problem still unsolved?
Is it concisely described?
Bounty for the best solution
Provide a bounty for the best solution
Bounties attract serious brainpower to the challenge.
- in batteries (most common solution for commercial use)
- in supercapacitors (storing large amounts of electrical energy in the form of electrostatic charges)
- by pumping the water up in the reservoir (hydroelectric)
- by compressing air and later decompression
- by flywheels and kinetic energy
- by thermal energy storage (chilling ice and later using it as a cooler, or by melting salt)
- by producing pure hydrogen from hydrocarbons
- by rail energy storage (heavily loaded trains are sent uphill and generate electricity via regenerative breaking systems when they go down)
Storing energy as multi-purpose ice glaciers
- for irrigation and drinking
- for cooling the electric systems and engines during extreme heat periods (ice storage air conditioning)
- for energy generation via hydroelectric systems (melting of the glaciers during warmer periods; the method described in the session text)
- for energy generation via Darko Savic's idea described here
- alternatively, they could be made in different shapes (like described here) and become a cool tourist attractions
