Peripherals/Energy Storage

In an environment where grid power may only be available for a few hours a day, or where energy generation is available but either generation or usage isn't constant an energy storage system is required.
A desirable storage technology would allow easy top-up and extraction of electricity. The input to the storage system wouldn’t necessarily need to be electrical but it would be preferable not to require a distribution system to be implemented.
For example, zinc-air fuel cells offer some interesting advantages over standard batteries, but require a zinc distribution system to be setup in conjunction with the technology.
Below is a list of technologies which offer possible solutions;
- Car Batteries
- Deep Cycle Batteries
- Compressed Air
- Supercapacitors / Ultracapacitors
- Nanoengineered Battery
- Flywheel Storage
Advantages and Disadvantages
Storage Type | Advantages | Disadvantages |
---|---|---|
Car Batteries | Text | Inefficiencies in getting energy into and back out of the battery (You loose half the energy [1]) |
Deep Cycle Batteries | Text | Text |
Compressed Air | Text | Text |
Super/Ultracapacitors | Ability to release quick jolts of electricity and to absorb this energy just as fast | Less energy storage capacity per Kg compaired to Batteries (25 times less [2]) |
