A completely renewable baseload electricity generation system is proposed by combining wind energy, compressed air energy storage, and biomass gasification. This system can eliminate problems associated with wind intermittency and provide a source of electrical energy functionally equivalent to a large fossil or nuclear power plant. Compressed air energy storage (CAES) can be economically deplo...

The injection of carbon dioxide (CO2) in deep, unmineable coalbeds is a very attractive option for geologic CO2 storage: the CO2 is stored and at the same time the recovery of coalbed methane (CBM) is enhanced. The revenue of methane (CH4) production can offset the expenditures of the storage operation. Coalbeds form complex gas reservoirs characterized by their dual porosity: they contain both...

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...

The use of Horizontal wells is a common method underground natural gas storage (UGS), but there still need to discuss whether they are more suitable for slotted liner or perforation completions. To address this issue, numerical model developed predict the injection rate horizontal while considering skin factor. Here, novel uncoupled iteration employed determine factor deriving from turbulence i...

Compressed Air Energy Storage (CAES) is a process for storing and delivering energy as electricity. A CAES facility consists of an electric generation system and an energy storage system. Only earth based geological structures can currently store adequate potential energy in the form of a pressurized air mass required by commercial electric turbines. Earth based structures suitable for service ...
