Much like carbonated drinks are water infused with carbon dioxide, gas hydrates are ice mostly infused with methane, a natural gas used as fuel. Gas hydrates are ice-like substances that usually only form beneath the seafloor, where the pressure is high and the temperature is just below the water’s freezing point of 0°C.
