Can natural gas from shale save climate bill?

Some Senators see incentives for natural gas from shale as a way to win more support for a climate change bill in their chamber. Leading the way to add those incentives are Colorado Sens. Mark Udall and Michael Bennett, the latter a swing vote himself.

New discoveries of shale gas (not to be confused with dirty shale oil) reserves, plus the technology to drill for it, have made shale gas a cleaner replacement for coal to make electricity, as well as a potential backup for wind and solar. Natural gas has about half the carbon emissions of coal. And wind and solar will need a backup, at least at the start, because of their dependence on the weather. Natural gas generators can be fired up quickly to serve that purpose.

New discoveries have increased natural gas reserves in the past couple of years, from 1,300 trillion cubic feet in 2006 to 1,800 tcf in 2008, mostly in shale, according to a report by the Potential Gas Committee.

The political potential

Lo and behold, many of the gas reserves in shale are in the homes states of uncommitted Democratic senators: Blanche Lincoln and Mark Pryor of Arkansas, Robert Byrd and Jay Rockefeller from West Virginia, Carl Levin and Debbie Stabenow of Michigan, Mary Landrieu from Louisiana, and Arlen Specter of Pennsylvania – as well as Republican George Voinovich of Ohio.

When the House version – the American Clean Energy and Security Act – narrowly passed, the majority of reps from Ark. Ohio, La. and Penn. voted against it (as well as Texas. Okla. and Ky.) and the W. Va. delegation was evenly split.

Natural gas vs. coal
Incentives for natural gas would pit the gas industry against the coal business. Natural gas would benefit from the proposed cap on emissions because it will lead to a quicker changeover from coal. And the gas industry favors fewer offsets, which would allow coal-fired utilities to stall in making changes by contributing to forests and other projects.

The coal business, not surprisingly, is worried about losing out to natural gas under climate legislation and opposes incentives that could speed that transition. The American Mining Association is running ads pointing to the volatility of natural gas prices and warning of spiking electricity costs. They’re not going to give up without a fight, so it remains to be seen which is strongest in vying for these senators’ loyalty.

But natural gas from shale, though not clean enough in the long run, just might help us over two humps – the transition to totally renewable, clean energy and the passage of a climate bill by both houses of Congress this year.
