“…One of the main purposes of developing MGHs is to maximize the economic benefit by using suitable technology in a safe environment. The two important parameters involved in the economic evaluation are the energy efficiency ratio (EER, ratio of combustion heat to decomposition heat in unit) and the energy return on energy invested (EROI, ratio of energy output to energy input during production) [70]. On the one hand, EER is affected by the production method, with the depressurization having the maximum energy efficiency; on the other hand, the reservoir type (Section 3.1.1) is also an important factor.…”

“…The method of substitution of methane in hydrate for hydrogen sulphide was considered in [6]. Economic analysis of the application of gas hydrate technologies in comparison with traditional methods of gas supply was carried out in [7]. However, it should be noted that the approximating functions in which the hydrate formation processes are described are not given in the known papers.…”

“…However, there are still some challenges on kinetics of methane production from CO 2 injection and CO 2 formation, and the deep understanding of the replacement process [22]. Chen et al [23] proposed that the volume of energy return on energy invested (EROI) can be regarded as an indicator of natural gas hydrate exploitation efficiency; improved technologies can help to increase the exploitation efficiency. Janicki et al [24] concluded from the German research project that reservoir permeability and available heat have important effects on hydrates decomposition.…”
