A complex for land adsorptive storage of natural gas, methane comprising:

• a gas treatment unit,
• a gas compression unit, and
• a gas storage unit having constant pressure,
• wherein the gas treatment unit, the gas compression unit, and the gas storage unit are successively arranged, the gas storage unit comprising one or several land gas adsorptive storage modules each of which is a high-pressure tank the bearing wall of which is made of cast-in-situ reinforced concrete reinforced with pre-stressed rods, or has a combined design of a series of layers made of metal and cast-in-situ reinforced concrete reinforced with pre-stressed rods;
• wherein the inner surface of the tank is lined using a gas-barrier material, the tank is filled with a microporous adsorbent to the extent not exceeding 97% of its internal volume, and said adsorbent accumulates at least 155 nm3 of natural gas per 1 m3 of adsorbent.
