Jeez - I had never read that piece and was unaware of the heat content issue:

Technical issues surround physical characteristics of an LNG cargo from a specific liquefaction facility to a specific regasification terminal. The heat content of LNG can range between 1,000 and 1,162 Btu per cubic foot (Figure 7). High heat content is incompatible with many U.S. appliances and industrial processes. Thus major interstate pipelines have a heat content specification of 1,035 Btu per cubic foot, with a range of plus or minus 50 Btu.

It seems a good deal of the natural gas from overseas is higher than that range (anything above the yellow band). How hard is that infrastructure to change?

OK, Amazing.

It's rare to hear about too *much* energy here :-)

I always assumed that the warmed LNG had added nitrogen or CO2 or something inert added to it.

OK -- stabilization

Stabilization is the addition of a gas to the gas normally supplied for the purpose of adjusting the heat content to a specified value. Air is often used for the purpose of reducing heat content and LP gases are used for the purpose of enriching or raising the heat content.
