... disadvantages of UHS in Australia compared to alternative technologies such as underground gas storage (UGS). Under current expectations, both the storage of hydrogen-methane mixtures and pure hydrogen cannot make considerable economic profits without policy support in the near future. The commercialization...

... Abstract Methane adsorption in shale is result of gas-liquid-solid interaction rather than gas-solid interaction by considering the initial water saturation in actual condition. As an important constituent of inorganic matter, clay minerals can provide additional adsorption capacity due to high...

... that of the seam. Isotherms are known to vary markedly with temperature. The hotter the coal, the less gas it will hold for a given pressure. Salmachi and Haghighi (2012) report a 50 percent reduction in methane storage of coal between 35°C and 75°C. The measurement of isotherms for coal may be conducted...
