The paper presents methods for determining the heat of formation of clathrate hydrates. The methods for calculating the specific energy of hydrate formation are analyzed. An energy description of the hydrate formation process in the systems is presented: solid hydrate former solid phase of water (ice), hydrate former - solid phase of water (ice), hydrate former - liquid phase of water, hydrate former under critical conditions - liquid phase of water. A comparison is made of the values of the specific heat of formation (dissociation) of gas hydrates from liquid water, ice, hydrates of liquefied gases, as well as mixed systems of hydrate formers, obtained experimentally and by calculation. The discrepancies in the values are in the range from 0 to 4.98 % and average 2.14 %, which allows us to state that the mathematical description proposed in the article is sufficiently reliable Keywords: hydrate formation, hydrate former, clathrate hydrates, dissociation, specific heat.
