We analyse the kinetics of CO₂ and methane hydrate formation. The characteristic formation times are associated with different steps of the formation process. Conditions for minimising these rate times are identified while maintaining a regime where CO₂ hydrate is formed and methane remains predominantly gaseous. This involves a rapid pressurisation routine and accesses points well above the phase boundary in order to enable faster kinetics. Conditions for optimising rates and times, to obtain maximum CO₂ uptake with respect to CH₄, were identified as (1) stirring faster than 1,000 rpm, (2) rapid pressurisation to a partial pressure of around 50 bar for CO₂ and (3) re-use of contaminated as opposed to fresh water.
