Capital costs of natural gas hydrate (NGH) and liquefied natural gas (LNG) are compared, for the transport of 400 MMscf/d (about 4 billion Sm3 per year) of natural gas for a distance of 5500 km. The NGH chain was found to cost about twenty-five percent less than the LNG chain. Studies in Norway have shown that frozen hydrates at atmospheric pressure remain stable long enough to make large-scale and long-distance transport of natural gas in the form of hydrate feasible.
