Electrical conductivity of pure CO2 hydrate and CH4 hydrate: Role of the guest molecule

To conclude a series of DOE-sponsored laboratory experiments in which our team measured
electrical conductivity of methane hydrate-bearing samples, we investigated electrical conductivity of CO2 hydrate for direct comparison with methane hydrate. Their surprisingly distinct signatures could aid in the monitoring of CO2 in certain deep marine environments. To the best of our knowledge these are the first reported conductivity measurements on pure, polycrystalline CO2 hydrate.
