I can not stop thinking about which is the best way to store electric power...
I need to store electric power for the refrigerator, freezer and radiocomunications. That can not be discused.
I do not worry about energy or power density, specific energy or specific power or self-discharge or even effiency but I would like to know which battery could last more time...
On the other hand, would a mechanical system that stores potential energy (i.e. water pumps) be able to compete with the life of the battery with the longest life cycle?
Thanks a lot.
and forgive my English.
It would help a lot to know where you are. Ambient temperture, and soil temperature can both play a role in an effiicient system.
First, be sure you have the most efficient refrigerator and freezer available. Common appliances are not that all efficient.
Everything I consider is a matter of re-engineering a given situation. We went to water cooling a refrigeration system rather than air- heat exchange and improved the efficiency by a factor of ten.
As to radio communications, reception can be accomplished with only a few watts, but transmitters can eat up the power. To improve a transmitting system, improve the antenna and get the same coverage with less power.
Storing power is a situational thing. storing water behind a dam or in a tower is an excellent way to store electricity- use it when you need it.
Hydro electric and wind driven generators need storage but at very different levels.
Battery storage is best achieved with Nickel-Iron batteries, but they are quite costly. Lead-acid batteries are plentiful and cheap, but they need constant care and more frequent replacement. Our lead-acid battery storage system lasted ten years- nickel-iron batteris can last 30 years, even longer, but they cost much more initially.
