Potato starch as methane hydrate promoter

► Potato starch as methane gas hydrate promoter. ► It increases the methane hydrate formation rate effectively. ► At 500 ppm, it has maximum acceleration effect comparable to SDS equivalent solution. ► Maximum hydrate storage capacity of 163 is achieved using 300 ppm starch solution. ► The best condition for storage is the pressure of 10 bar and temperature of 268.2 K.
