Build the GTL refineries on floating platforms out at sea, where the methane is being recovered, either from deep-water natural gas wells, or from Methane Hydrate mined from the ocean floor, where it exists as an amorphous solid at depths of 1,000 to 3,000 feet, and the water temperature never rises above about 38 degrees Fahrenheit.
It is estimated that there is perhaps a thousand times more energy captured in these accumulations of Methane Hydrate on the ocean bottom, than all the other known and estimated reserves of all other fossil fuels combined. And it is constantly renewing, as more anaerobic decomposition of organic materials goes on all the time.
Where did you think whale feces went?
Well not to bust any enviroweenies bubble, but evidence is that stardard crude is also a slowly self renewing resource as well...not made up of decayed dinosaurs.... But hey, don't tell the greenies that... it'll blow their minds.
Brilliant! We turn a threat, methane hydrate, into clean burning fuel. We could then fertilize the oceans to encourage plankton growth which recycles carbon dioxide into the deep ocean. Oh yeah, there would be more fish to supply protein to the world's poor people. BTW, the primary fertilizer needed is iron which some oceans are deficient in.
