Cheaper Natural Gas from Coal

n the second half of the 20th century, oil- and natural gas-burning furnaces drove coal out of the home-heating business across North America. But if Great Point Energy--a Boston-area startup with a low-cost process for converting coal into pipeline-grade natural gas--has its way, coal may start keeping us toasty again before long.

Great Point Energy of Cambridge, MA, says its process is cheaper and more reliable than drilling for new natural gas or importing liquefied natural gas from the same unstable regions. "We can take coal out of the ground and put it in a natural-gas pipeline for less than the cost of new natural-gas drilling and exploration activities," says CEO Andrew Perlman
