What is the cheapest way to store electricity ie as ammonia etc

[Rmaxd]

I was thinking of storing around 1-10 kilowatts, maybe transfer it to something like liquid hydrogen, or use it to create ammonia

It's basically to replace electric generators & tractors

I dont need anything long range, as theyre all close by

Im not concerned about the cost, as long as it doesnt contain expensive materials & chemicals

So basically a cheap medium to store around 1-10 kilowatts, or more, im not concerned about the inefficiency of the process or the inefficiency of the material

A list of methods or materials to convert 1-10 kilowatts of electricity

thnx

Cheapest...Well I dunno, but safest and less side effects;

Non-Chemical;

(1) Electric Grid Intertie /with appropriate agreements/

(2) Compressed Air

Chemical with Carbon Free;

(3) Hydrogen Gas 2H - Compressed Gas or in metal matrix - Water Feedstock

(4) Hydrogen Peroxide  H-O=O-H - liquid - Water Feedstock

(5) Ammonia H3N - liquid - water and air Feedstock

Organic Chemical

(6) Carbon Monoxide Gas - CO

(7) "Bingo" Gas Hydrocarbon

(.8.) Methane Gas Hydrocarbon - CH4

(9) Acetylene Gas Hydrocarbon - H-C=C-H

(10) Methyl Alcohol - Methanol - CH3-OH

(11) Ethyl Alcohol - Ethanol - C2H5-OH

Each need to be evaluated as to safety and how it is going to be used
I see the Carbon containing chemicals compounds as being recycleable.
These are all simple compounds because I surmise that the simpler the
compound equation the less QA quality assurance is necessary to be
sure what you are getting from the process is the real deal.

Many of these things are combustable in engines, some would require
specially designed engines, most are combustable in fuel cells though
perhaps specialised fuel cells would be required.

Some of these things a explosive, some are flamable in air, some
are flamable if air/oxygen gets injected into their storage, some are
noxious.

I happen to like compressed-air (except for the noise) because you can get energy gain
via storage if you for example, compress the air at night and then play it back during the
day you will get a form of solar energy conversion. Note that finned heat sinks are less
susceptable to damage then are solar panels.

Hydrogen Storage is probably the most refined if one is willing to put engineering into it.
One should indeed check out those hydrogen catalytic metals here because they
promise a closed hydrogen/water cycle with small energy waste.

I also like ethanol because it is non-toxic liquid with a fairly high ignition temperature
and would dilute out with water but I suspect the chemical loop reprocessing would
be somewhat more complex. You can denature it with some small amount of methanol.

Hydrogen peroxide is somewhat explosive in it's high concentration form and is
suceptible to LENR cavitation excitation. Carbon monoxide sounds crazy but if you
can keep people away from it it actually gets used as a fuel gas in steel furnaces etc.

You could also melt salt with it, and use the melted salt as a heat(energy) storage.


Solar plants are using this as well.

Thanks for the great list mscoffman, much appreciated

Could you put a rough energy conversion efficiency ratio for each, as itd help me narrow it down alot quicker

Im leaning towards liquid hydrogen atm, as cooling, gas leaks, etc, the solutions are all electrical ie tecs

Btw are capacitators high enough to store kilowatts yet?


Thnx

well, If you are looking to go on tha cheap and off tha shelf..... why not capacitors? 10800 micro farads equal a AA battery- 2.8 amphours of energy. 10 AA batteries are equal to 1 capacitor rated at .1 farad (if discharged at the same level) @ equivalent voltages.  that's around 15 volts at 2.8 amps per hour. in the size of an aspirin bottle..... I'm thinking farms ........
