Natural gas is often seen as an ideal option to optimize China's unsustainable energy mix. Gas could improve the country's environment because of its lower air pollution and carbon emissions. Abundant domestic gas supplies could also make the country less dependent on energy imports, a longstanding goal of Beijing. Demand for gas is planned to grow to 260 billion cubic meters by 2015, up from 108 in 2010, an astonishing annual growth rate of almost 20%.

But since gas production increased by only 14% a year between 2006 and 2010, China needs to either quickly ramp up its domestic gas supply or increase its gas imports. That domestic supply is greater than is generally believed, given common story lines about how China lacks energy resources. According to the U.S. Energy Information Administration, China has more technologically recoverable shale gas than any other country in the world, enough to fuel the entire Chinese power sector—the largest in the world—for 30 years.

This is inspiring Beijing to dream of a U.S.-style shale gas revolution for China. Shale gas supplied less than 2% of U.S. gas output in 2000, but 10 years later it reached 23% and is projected to account for 49% by 2035. America's dependence on imported oil as a percentage of national consumption has rapidly diminished from 60% in 2005 to slightly over 40% today.

To gain access to state-of-the-art shale gas technology, both China National Offshore Oil Corporation and Sinopec have recently made strategic investments in North American shale gas assets. At home, after a rather disappointing round of bidding for shale gas drilling rights in June 2011, when only six state-owned companies were invited to participate, the Ministry of Land and Resources announced last month the second round of bidding. Realizing that America's shale revolution has been powered by small- and medium-sized enterprises instead of Big Oil, Beijing also is allowing Chinese private enterprises and Sino-foreign joint ventures (as long as they're controlled by Chinese parties) to bid.

But China is hardly on track to replicate America's success. Several factors still threaten to trip up Beijing's efforts to bring the shale revolution to the Middle Kingdom.

"Technologically recoverable" is not the same as "economically recoverable." Shale gas deposits in China are generally located in mountainous areas and remote deserts, and are buried deep underground. While the technology exists to extract gas in those conditions, it's not cheap. Drilling costs in China have run as high as $16 million per well, compared to only several million dollars in the United States.

This need for capital is related to the weakest link of China's shale gas industry: the country's inability to attract the right types of developers and incentivize private enterprises to spur much-needed innovations. Major international players, while interested in investing, are well positioned to resist transferring critical technological know-how to their Chinese counterparts—which effectively leads to a prolonged learning curve.

Despite some signs of openness, China has struggled to attract investment from smaller foreign players. Beijing already faced an uphill slog since many smaller American drillers face financial troubles due to low gas prices in their home market. Making matters worse, the legal vacuum for shale gas development (including licensing, exploration and production); a lack of intellectual property rights protection for technology; low gas prices in China; and a dearth of easily recoverable fields for new entrants all are deterring investment.

Beijing also has a hard time attracting the right kind of domestic developers. China lacks strong protections for private property rights, especially in the energy industry. Shale gas investors will have noticed the most recent consolidation of the Shanxi coal industry starting from 2009, in which the government forced mergers among ostensibly private mines and mostly benefited state-owned companies. Not surprisingly, private investors in China are more likely to be interested in short-term speculation instead of long-term investment in research and development that is key to a Chinese shale gas revolution.

Nor will China necessarily reap environmental rewards from shale gas. Hydraulic fracturing—which uses pressurized fluid to break up the shale deposits that contain the gas—is water-intensive and many shale gas fields in China face serious water shortages, making it difficult to scale up output. Even in regions where water availability is less of a concern, inexperienced or irresponsible drilling practices risk fresh water contamination.

Though China currently has only 62 shale gas wells in trial development zones, Beijing has recognized the importance of water management in China's Shale Gas Development Plan for 2011-2015. Even so, China's problematic environmental enforcement records and the country's highly fragmented water governance mechanism certainly do not necessarily hold the promise of moving the water management agenda toward the right direction.

Shale gas can improve China's environment and energy security. But there are too many barriers that will prevent China from duplicating America's success. The shale revolution can certainly spread across the Pacific one day. But for that to happen, Beijing will need a major revamp of basic policies such as protection of property rights.
