Natural Gas: Past, Present, and Future
Posted by David Foster on 14th May 2012 (All posts by David Foster)

The hot energy story of the last few years has been the vast expansion in the available supplies of natural gas, and the very significant economic implications thereof. I though it might be interesting to take a look at the past, present, and future of this commodity.
The first known use of natural gas was by the Chinese, circa 500 BC…they captured gas from places where it was seeping to the surface, transported it in bamboo pipelines, and burned it for a heat source to distill seawater and capture the resulting salt and fresh water. The modern gas era began circa 1800 with the use of gas for lighting–initially of streets and later of homes and other buildings. Since there was no network of gas wells and long-distance pipelines, the gas used for these applications was usually not true natural gas, but rather “town gas,” made by heating coal. (Gas stoves seem to have become popular circa 1880, and apparently had quite an impact….I’ve read that the term “gas-stove wife” was enviously applied to women who were so fortunate as to have one of these appliances and were thereby spared the labor of tending a wood or coal stove, and hence had some leisure time available.)
The transition from coal gas to true natural gas had to wait on the build-out of a long-haul pipeline network, which took place mainly from 1920 to 1960. Although electricity became the glamor “fuel” and displaced gas in many cases for cooking and heating, the generation of electricity itself has in recent years become a major source of gas demand. Natural gas is also important as a feedstock for the production of fertilizer and of various plastics. By the early 2000s, there were serious concerns that the US was running out of natural gas–see for example this 2003 TIME Magazine story. The article cites Alan Greenspan’s concerns that high nat gas prices would make us uncompetitive in many industries, as well as citing direct economic pain inflicted on consumers. The only solution seemed to be large-scale imports of natural gas via LNG (liquified natural gas) ships. (Gas is far more difficult to transport than oil, because it needs to be liquified in order to make the volumes manageable, which in turn requires refrigerating it to very low temperatures.) In late 2005, US natural gas prices hit an inflation-adjusted level of almost $16 per million BTUs.
The price is now about $2.50 per million BTUs. What happened?
