Shale Natural Gas vs. Renewable Energy — Continued — Guest Blogger Anil

Here’s more about shale natural gas:

Pundits in the US natural gas industry have revised supply estimates in last few years. In effect, some companies claim to be able to increase sustainable production over the long term.

Exxon is a big player in energy by any standards and the company’s halo effect is likely to bring about the positive change for the market participants including natural gas explorers, producers and transporters. The deal has overnight changed the sentiments for shale natural gas. In a recent deal, Carrizo Oil & Gas sold some of its stake in a Texas shale project to Sumitomo Corporation for US$15.7 million.
Onshore produced shale gas with lower transportation costs is likely to be used in electricity generating plants (replacing coal), heating and cooling our homes and power automobiles. However, it would be wrong to conclude that natural gas is the sure shot remedy to all our energy issues. ExxonMobil has some synergies to justify a 25 percent premium on XTO Energy. Besides being an oil giant, ExxonMobil has a chemical business and thus can use the feedstock in any of its chemical facilities.

In the US, shale gas resources are very large and relatively evenly distributed over several states unlike oil. Some analysts claim that the shale gas could contribute up to half of the US total gas production by 2020. Such a scenario would be highly satisfying for US with reduced dependence on not just foreign oil, but also from greener sources which are highly dependent on specific countries for key components (Read rare earth metals in China and lithium supplies in Bolivia).

A recent run-up in the stock prices of shale gas companies warrants for a caution. Like other times, it appears that Wall Street has underestimated the real cost of shale gas, and overestimated how fast its production can be expanded. Some studies point towards the overestimation of shale gas supplies by some companies. Also, there are some concerns regarding the long term viability of shale gas extraction in a lucrative manner.

Empirical data tells us that the production in shale formations drops off rapidly after two to three years of high production. However, it will be too early to write off this option only on the basis of high price, that also when a lot of other energy sources are getting federal grants for relatively expensive technologies. The competitive landscape is expected to become clear in next two to five years after the production of shale gas starts on a mass scale. In due course of time, we’ll come to know if all this hype is real or just fizz.
