More attention paid to all the natural gas we’re wasting

Energy experts are starting to pay more attention to an important byproduct to U.S. oil extraction: the incredible amount of natural gas that gets burned off into the atmosphere, or “flared,” because it’s not profitable enough to capture at the well head.

Forbes contributor Michael Kanellos is the latest to examine the absurd practice, writing:

… the sheer volume of gas that gets flared or emitted into the atmosphere t remains truly astounding. A potential source of profits and jobs is literally transformed in bulk into an environmental hazard and potential liability around the clock.

It’s an environmental hazard because natural gas is made primarily of methane, a greenhouse gas that’s many times worse for the environment than carbon dioxide. Some methane leaks from wells and pipelines, but even when the gas is burned off, it creates some GHG emissions.

Methane has tremendous potential as a commodity, however, because it can be turned into alcohol fuels — ethanol and methanol — to run our cars and trucks. Both fuels burn much cleaner in engines, and can be cheaper for the consumer.

When the price of oil was $115 a barrel, there was little incentives for oil drillers — who put bits in the ground mainly for oil, after all — to capture and store the natural gas, because gas remains stuck in the cellar in terms of pricing. Now that oil has dropped by 60 percent over the past seven months, maybe U.S. drillers will be incentivized to keep more of the gas that comes up in the wells.

(Our blogger William Tucker has written about the flaring issue before. It’s also discussed, along with many oil-related issues, in the documentary PUMP, which is available for download on iTunes now.)

Landfills also emit methane, and much of that is flared as well. If we captured more methane and turned it into fuel, there would be more of a market for it, and the infrastructure for converting it to fuel and distributing it would grow. A whole new generation of jobs could be created in the sector, jobs that by their nature would stay in America.

Kanellos has compiled many fascinating statistics about how much natural gas is wasted by flaring, including these nuggets:

  • Since the beginning of 2010, more than 31% of the natural gas in the Bakken region has been burned off or flared. It was worth an estimated $1.4 billion.
  • Over 150 billion cubic meters, or 5.3 trillion cubic feet, get flared annually worldwide, or around $16 billion lost.
  • Flaring in Texas and North Dakota emit the equivalent amount of greenhouse gases as 500,000 cars.
