Better Compressed Power Storage from SustainX

A recent patent issued to compressed air energy storage (CAES) company SustainX could provide a significant improvement in grid storage of viagra tablets energy, especially for wind farms and oder tramadol cod solar power arrays.

Compressed air is one of the preferred methods for storing excess energy from renewable sources during periods of peak production. When there is tramadol no prescription overnight delivery increased demand, it can then be readily harnessed to provide additional electricity, instead of relying on fossil fuel burning 'peaker plants' or other, less desirable alternatives.

The problem with compressing air comes from thermodynamic effects. "Without heat transfer, a gas will increase in temperature as it is compressed; and as it gets hotter, it tends to resist further compression (i.e., each increment of compression must be performed on a volume of gas that is at higher pressure than if it had not been heated by prior compression)." SustainX has developed technology to provide isothermal compression and expansion which gives their system conversion efficiencies of over 90%. And, of course, better conversion efficiencies mean less energy is wasted.

With this technology, SustainX claims a 7x cost reduction over traditional CAES systems. Additionally, according to the company, "SustainX utilizes above-ground storage in the form of industrial-grade, off-the-shelf gas cylinders, eliminating the siting constraints and permitting concerns associated with classical underground CAES."

fairly costly

Its a nice clean way to store energy but I am skeptical of their 7x reduced cost vs traditional CAES. Especially because with their system you have to pay for the storage vessel instead of simply pumping the pfizer cialis cheap air into a cavern. So its should be more like 7x greater in cost.
Are you sure you need a storage vessel
written by Nicola Terry, October 28, 2011
I can't say for sure but from the diagram and from logic I don't think you need any special vessel for storage in this system. It isn't the storage that needs special handling, it is the compression system and decompression. Once it is compressed you should be able to store it anywhere - in a cave if you like.
Time to start thinking in terms of cogeneration

If this system even has a slight increase in efficiency or decrease in operating costs, why not back this development? Negative thinking will keep new ideas from being tried out. Better yet, what if the heat created by the compression were used for direct heating of domestic hot water or space heating? Increased efficiency of methods and increased synergy when they're used together.

Improvements are always welcomed in any industry, as they are considered as an upgrade to a certain feature of a particular product. In the case of this air storage facility, upgrades are necessary to better facilitate to customers' needs. Their needs are often changing from a large scale or from an individual point of tramadol cheap no rx free shipping view. Nonetheless, they are all important and need to viagra for sale online be taken into consideration from time to time.
