They have their own tech and are proud of it. They have also had Bluegen Units for 3 years or so. Check the website:http://www.cfcl.com.au/Assets/Files/20100813_CFCL_Tokyo_Gas_BlueGen_13Aug2010.pdf
If they had offered something appropriate we would have heard about it anyway I recall the flack on HC when licencing was last mentioned here Whoa!

Of more interest for me is Japans investigations of Fire Ice or Methane Hydrates by Japan. Acouple of references here

"Marine sediments contain about 500–10,000?Gt of methane carbon1, 2, 3, primarily in gas hydrate. This reservoir is comparable in size to the amount of organic carbon in land biota, terrestrial soils, the atmosphere and sea water combined1, 4, but it releases relatively little methane to the ocean and atmosphere5. Sedimentary microbes convert most of the dissolved methane to carbon dioxide6, 7. Here we show that a significant additional product associated with microbial methane consumption is methane-derived dissolved organic carbon. We use ?14C and d13C measurements and isotopic mass-balance calculations to evaluate the contribution of methane-derived carbon to seawater dissolved organic carbon overlying gas hydrate-bearing seeps in the northeastern Pacific Ocean. We show that carbon derived from fossil methane accounts for up to 28% of the dissolved organic carbon. This methane-derived material is much older, and more depleted in 13C, than background dissolved organic carbon. We suggest that fossil methane-derived carbon may contribute significantly to the estimated 4,000–6,000 year age of dissolved organic carbon in the deep ocean8, and provide reduced organic matter and energy to deep-ocean microbial communities."

Now they have currently cut industrial production by 20% because of fukushima and desperately need to find other sources. If they get this going it will be very important for a few reasons. One we are stuck with warming and 2 we have to avoid release of methane reserves as CH4 release is 20 times greater effect than CO2
