How important is gas to China's energy mix?  

The Climate Spectator has a pair of article on EIA research into China's appetite for natural gas. The first looks at where China currently gets its gas from - How important is gas to China's energy mix?.

China more than tripled natural gas production since 2003, producing 3.8 trillion cubic feet in 2012, and the government is targeting production to reach about 5.5 Tcf of natural gas per year by the end of 2015. Most of the anticipated production growth is from large onshore fields in the western and north central regions of China as well as from the offshore deepwater regions in the South China Sea. China's natural gas consumption has outstripped domestic supply since 2007, triggering rising imports of both liquefied natural gas and pipeline gas. China's natural gas consumption rose at an average annual rate of 17 per cent from 2003 through 2013, reaching nearly 5.7 Tcf in 2013.

In 2013, China imported nearly 1.8 Tcf of LNG and pipeline gas to fill the growing gap between supply and demand. Imported natural gas met 32 per cent of China's demand in 2013, up from 2 per cent in 2006. China is swiftly developing its LNG import capacity in the urban coastal areas and currently has 10 major regasification terminals with 1.7 Tcf/y of capacity. In 2012, China rose to become the third-largest LNG importer in the world, after Japan and South Korea, and in 2013, the country imported 870 billion cubic feet of LNG. Estimates for the first half of 2014 show LNG imports growing at faster levels than in previous years.

The second article looks at the supply situation from Russia - China's gas equation, post-Gazprom.

Russia's largest natural gas company, Gazprom, finalised a deal with the Chinese National Petroleum Corporation in May. New natural gas production in Russia will mainly come from fields in eastern Siberia, which currently lack export infrastructure. The planned Power of Siberia pipeline will export gas south to China and east to a liquefied natural gas plant on Russia's east coast.

This contract is Gazprom's largest to date. Gazprom has a monopoly on pipeline natural gas export contracts made by Russia. The situation differs from that in LNG markets, where other companies such as Rosneft and Novatek may participate.

China's northern and eastern provinces have growing natural gas demand that cannot be met by existing pipelines or LNG, and the new Russian natural gas will mostly go to meet demand in these regions. China has also committed to purchasing 38 bcm (1.3 Tcf) per year of natural gas from Turkmenistan by 2016, increasing to 65 bcm (2.2Tcf) per year by 2020.

As a footnote, Technology Review has an article on China's problems trying to develop shale gas - China’s Shale Gas Bust.

In 2013 China became the third biggest user of natural gas behind the United States and Russia, consuming 166 billion cubic meters (bcm). By 2019, the International Energy Agency expects China’s annual natural gas consumption to grow 90 percent, to 315 bcm. Half of that increase is expected to be supplied by domestic gas production, which would come from multiple sources, including shale reserves.

That IEA estimate for gas consumption is much lower than the production target China had set for itself: 420 bcm of natural gas annually by 2020, with hydrofracturing, or fracking, being used to get 60 to 80 bcm from shale.

China is estimated to hold the largest technically recoverable reserves of shale gas in the world—nearly twice as much as the U.S. But the shale industry in China has struggled to get off the ground. Most projects are still in the exploration phase. In many cases the formations that hold gas are deeper than in North America and more expensive to reach. Further, Chinese shale tends to have more clay in it, which is an obstacle to extraction (see “China Has Plenty of Shale Gas, But It Will Be Hard to Mine”). These challenges led the government last week to reduce the 2020 shale-gas target to 30 bcm.

Even that would represent a huge increase. Of the 117 bcm of natural gas that China produced in 2013, only 0.2 bcm came from shale.
