Inhibition of methane and natural gas hydrate formation by altering the structure of water with amino acids. [PDF]

Sci Rep, 2016
Natural gas hydrates are solid hydrogen-bonded water crystals containing small molecular gases. The amount of natural gas stored as hydrates in permafrost and ocean sediments is twice that of all other fossil fuels combined.
