Online Monitoring of Geological CO2 Storage and Leakage Based on Wireless Sensor Networks

ABSTRACT:

           Atmospheric concentrations of the key greenhouse gas (GHG) carbon dioxide (CO2) well above pre-industrial levels constitute the main cause for the predicted rise at average surface temperature on Earth and the corresponding change of the global climate system. CO2 Capture and Storage (CCS) is on the one hand an effective way to realize effective greenhouse gas storage, and on the other to improve oil and gas production. Many countries such as the United States, Japan, and Canada are in search of effective approaches for CO2 storage in either geological formations or ocean. However, once CO2 leaks from the storage reservoir, all the efforts human beings have made to fight global warming would be go down the drain. Therefore, what is in needed after the geological CO2 storage is long-term terrain monitoring of the greenhouse gas leakage, which is absolutely crucial to help ensure that geologic sequestration of CO2 is safe. For this reason, the development of remote online monitors system is of great significance to geological CO2 storage and leakage warning In exiting system, they only collecting the environment parameters and analyses there is no system to share the data to the data center server. In the proposed system we use the PIC microcontroller in monitoring section. Array sensors sense the environment parameter like Co2, Humidity and temperature. Sensors sends sensed analog value to microcontroller for analog to digital conversion. The location and timing of the collecting area can be finding with help of GPS. Here the ZIGBEE module continuously wirelessly transmits the collected information to the data center. Received data will be displayed in LCD
