CAES (Compressed Air Energy Storage)

What is Compressed Air Energy Storage

CAES refers to the compression of air to be used later as energy source.It can be stored during periods of low energy demand (off-peak),inorder to meet periods of higher demand (peak-load).
The first CAES systems were
constructed by Victor Popp in 19-th
centuary That was in 1870.


PARTS

1)Turbo-compressors
2)Turbo-expanders
3)Under ground vessels
4)Turbine & generator

A biogas reactor is an airtight chamber that facilitates the anaerobic degradation of blackwater, sludge, and/or biodegradable waste (e.g. animal manure, kitchen and garden wastes). It also facilitates the collection of the biogas, a mixture of methane (CH4) and carbon dioxide (CO2) produced in the fermentation processes in the reactor. The gas forms in the slurry and collects at the top of the chamber, mixing the slurry as it rises.The pressure exerted by the rising gas can be used to transport the gas to the collection vessel or directly to w ....etc

1. Abstract
Biogas is a clean environment friendly fuel. Raw biogas contains about 55 65% methane (CH4), 30 45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapors. Presently, it can be used only at the place where it is produced. There is a great need to make biogas transportable. This can be done by compressing the gas in cylinders which is possible only after removing its CO2, H2S and water vapor components. Pilot level trials to compress the biogas have been carried out ....etc

Pumped hydroelectric and compressed air energy storage (CAES) are currently economic for utilities when relying on natural geologic formations and the cheapest, most abundant substances (i.e. elevated water and compressed air). In these situations the cost of energy storage capacity can be very low (<$5/kWh1) Unfortunately the scale and location-specific nature of energy storage in natural formations is likely to render it of limited benefit to small scale distributed renewables. Available pumped hydro and CAES capacities could prove small in r ....etc

Abstract
Biogas technology, besides supplying
energy and manure, provides an excellent opportunity
for mitigation of greenhouse gas (GHG)
emission and reducing global warming through
substituting firewood for cooking, kerosene for
lighting and cooking and chemical fertilizers. A
study was undertaken to calculate (1) global
warming mitigation potential (GMP) and thereby
earning carbon credit of a family size biogas plant
in India, (2) GMP of the existing and target biogas
plants in the country and (3) atmos ....etc

The idea of compressed-air energy storage isn t new, but cheap and plentiful energy has precluded much research. The low-tech explanation goes like this: excess energy from a power plant is used to run air compressors, which pump air into an underground cave, where it is stored under pressure. When released, the air powers a turbine, creating electricity. The initial energy used to force the air underground can come from wind, solar, nuclear or any source.

The technology could also help utilities meet their peak demand by collecting energy ....etc

structure and function of biogas plant wikipedia

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. It is a renewable energy source and in many cases exerts a very small carbon footprint.

Biogas can be produced by Anaerobic digestion with Anaerobic ORGANISM, which digest material inside a closed system, or fermentation of bio ....etc
