MIT Technology Review: Where Is the Global Shale Gas Revolution?

The United States is not alone in having massive shale gas resources: shale formations rich in gas can be found all over the world. But so far no other country has come close to replicating the U.S. boom that has led to relatively cheap natural gas and helped curb yearly carbon dioxide emissions.

According to recent numbers from the U.S. Energy Information Administration, only two other countries—Canada and China—are now producing commercial volumes of gas from shale formations, a process made feasible relatively recently thanks to the development of hydraulic fracturing and horizontal drilling technology (see “Natural Gas Changes the Energy Map”).

Those countries lag far behind the United States in production, however. Though China, the world’s largest annual emitter of carbon dioxide, has nearly as much technically recoverable shale gas as the U.S. according to recent EIA estimates, challenging geology has been a major obstacle, and the country has had to scale back its near-term goals dramatically (see “China’s Shale Gas Bust”).
