The capital costs of natural gas hydrate (NGH) and liquefied natural gas (LNG) are compared, for the transport of 400 MMscf/d (about 4 billion Sm{sup 3} per year) of natural gas for a distance of 5,500 km. The NGH chain was found to was found to cost at least one-quarter less than the LNG chain. Independent studies in Norway, Canada and Russia have shown that frozen hydrates at atmospheric pressure remain stable long enough to make long-distance transport of natural gas in the form of hydrate technically feasible.
