Then there are the compressor stations which keep the gas moving through the pipeline. The Coastal GasLink pipeline will ultimately have eight of them. These all burn gas; one study indicated that, on average, a reciprocating compressor burned “45 000 GJ of natural gas during the reporting year and the flare burned 2400 m3 of processed natural gas.” That’s 42 million cubic feet of gas per year, a fraction of the 2.1 billion cubic feet per day that the pipeline carries per day, but equivalent to the consumption of 684 average American houses. A small matter, but just pointing out that every step of the way, from start to finish, there are leaks, flares, boil-offs, pumps and compressors eating up the gas.
