Thinking about Electricity Storage

Recommended Posts

Another option that is not electrical, and has the advantage that it uses material either that is already there, or is in plentiful supply.


Did you know you can store enough energy in a reasonable size cube (one that would fit under many gardens) to heat a house all winter.


So you can just collect solar energy through the summer (when you get most solar energy/day), store it in an insulated container, and retrieve the energy through the rest of the year.


A seasonal thermal store.


Obvious materials are: water, soil, sand.


It could be used for heating the house, heating water, and even cooking.


A heat to electricity converter could also add other output options.

Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) under pressure to form a previously unknown solid with unusual bonding chemistry. The experiments are the first time these elements have been combined to form a stable compound. The discovery debuts a new family of materials, which could boost new hydrogen technologies.

Beyond Battery Technologies


This topic has some interesting views and considerations, to which I want to add something about high density Amp Hour storage for long duration without chemical electrolytes. And hence this is another technology to invest in that has a great potential to grow beyond battery technologies for the numerous merits listed below.







Evans Capaterry Products


"Capattery style super capacitors are designed for longer duration power hold-up and memory back-up applications. Full operating temperature range of -55C to 85C." ~ Evans Capacitor


A salesman at Evans told me that the largest Capattery (a Super Capacitor) that they have made on special order was 300 Farads. Which is equal to 300 A hour at 1 volt. But these Capattery technologies can hold a much higher voltage than 1 volt. A 12 volt capacitor rated for 300 A hour is equal to a deep cycle marine battery.


The Super Capacitor is capable of charging faster than a chemical battery. And does not require maintanance. And does not have toxic chemical waste such as sulfuric acid, nor lead, not lithium to worry about. Hence is environmentally friendly. It can last for 20 years or more and can hold a charge that long too ~ with little loss.


According to a feature in the Federal Laboratory Consortium News Letter a fews years back. A new diamond deposit dielectric was invented that can make Super Capacitors of larger Farad values but smaller in size. And the diamond hard dielectric will hold up to larger voltages. Hence I am looking to see even more interesting Super Capacitor technologies.


Anyways this will solve the problem with batteries for use in hybird electric automobiles and home grid tie battery banks. Which have no chemical maintanance and which last longer, as well as will not create a enviornmental problem. The only reason the Evans and other Super Capacitor companies are not making larger stock sizes than 1 Farad. Is that at the moment no one has created a demand. But demand will bring such things to market. You can inquire of what Evans can do, and also check out other potentially new emerging companies that make Super Caps.


All you have to do is decide you want to invest into Super Capacitor technologies for green investments. And so, I would suggest that you keep an eye on this market and it's innovations and trends. And so, not always be looking at strictly battery technologies. I personally think these will make better batteries.

I would think a few times before hosting 100kwh of batteries in my basement, particularly of an untested technology. That aside, obvious this is a rather prospective area for research and batteries could be hosted more centrally as well.
