Abstract
A method is provided for producing CO.sub.2 hydrates. In the subject method, CO.sub.2 is first dissolved in water to produce a CO.sub.2 hydrate precursor. The CO.sub.2 hydrate precursor is then mixed with CO.sub.2 gas, resulting in hydrate production. Between the first and second steps, the CO.sub.2 hydrate precursor may optionally be cooled to at least 0.degree. C. and/or CO.sub.2 hydrate nuclei may be introduced into the CO.sub.2 hydrate precursor. The method is carried out in a continuous hydrate production reactor. The subject method finds use in sequestering CO.sub.2 gas emissions in the form of hydrates, where the hydrates are deposited in high pressure, low temperature environments, such as in the ocean at depths greater than 1000 m or in subterranean fresh water aquifers.
