Is CO2 sequestration safe?
Documented facts from hundreds of well-researched geologic studies conclusively demonstrate that CO2 sequestration is safer than many other industrial processes. CCS projects proposed in California plan to sequester CO2 beneath non-porous cap rock where it is expected to remain for millions of years — as long cap rock has held oil and gas reservoirs in place. A CO2 pipeline is very similar in operation to other gas and liquid pipelines already in widespread use throughout the world. Since CO2 is not flammable, there is no danger of fire, but compressed gas is under pressure and could displace displace oxygen in small, enclosed spaces. These factors require safety technologies, including electronic monitoring devices placed throughout the entire length of the pipeline that can instantly pinpoint leaks and automatically isolate the area and shut off the pipeline. Once available, a CO2 pipeline infrastructure can also be used to transport and sequester CO2 that currently vents into the a
