Ozone storage capacity in clathrate hydrates formed from gas mixtures of O3 + O2 + N2 + CO2 was studied. It was found that in such system the amount of ozone included in the hydrate phase can be at least several times higher than for the experimentally described O3 + O2 + CO2 gas hydrates. The most promising thermobaric conditions and gas phase compositions for the formation of ozone containing hydrates from gas mixtures which include nitrogen are suggested on the basis of the obtained results.
