Calculation of the eroei coefficient for natural gas hydrates in laboratory conditions

Abstract

Abstract. In the 1960s, scientists discovered that methane hydrate existed in the gas field in Siberia. Gas hydrates are known to be stable under conditions of high pressure and low temperature that have been recognized in polar regions and in the uppermost part of deep-water sediments below the sea floor. The article deals with the determination of the EROEI coefficient to generate the natural gas hydrate in the device under specific temperature and pressure conditions. Energy returned on energy invested expresses ratio of the amount of usable energy delivered from a particular energy resource to the amount of exergy used to obtain that energy resource. Gas hydrates have been also discussed before decades like potential source mainly for regions with restricted access to conventional hydrocarbons also tactic interest in establishing alternative gas reserves.

Assessing Global Long-Term EROI of Gas: A Net-Energy Perspective on the Energy Transition

“…Moeller and Murphy [48] calculated the EROI of the Marcellus Shale using a hybrid lifecycle analysis approach. Siažik et al [49] computed the EROI for natural gas hydrates in laboratory conditions. de Luna et al [50] quantified the EROI of biogas produced from microalgae.…”

Gas Hydrates as a Means for Biogas and Biomethane Distribution

“…Gas hydrates is characterized by high storage capacity. Theoretically, a given volume of gas hydrates contains more than 150-fold the same volume of gas at standard temperature and atmospheric pressure, which shows that gas hydrates are promising for gas storage (Mori, 2003;Siažik et al, 2017). Compared to other biomethane storage and distribution methods (i.e., gas grid, gas liquification, gas compression) hydrate technology has the advantage of high safety and flexibility (Wu et al, 2019).…”
