Yet more substitutes: Natural Gas from Shale powered delivery vehicles

Continuing on the theme of viable substitutes:

Many in the doomer camp say "we're screwed because we can't possibly replace all of our current oil production before we peak".

First of all, we don't need to replace ALL of our current oil production.

We ONLY need to blunt the decline rate.

Given that we can do this by substituting away some of the demand for the likely 1-2% decline rate the challenge seems much less insurmountable and great strides have been made so that we no longer have a need to destroy demand by 1-2% a year as we may have needed to do if peak oil had come say, in 2000-2002 when many of the substitutes we now have were not technically available.

One such substitute that is effectively a snap-in is the huge reserves of shale gas which have been developed in the United States through the progressive development of increasingly sophisticated horizontal drilling methods combined with advanced fraccing technology. This has led to the lowest prices for natural gas in the US and Canada in more than a decade because there is frankly a glut of supply.

This couldn't have come at a better time. We now have an arbitrage opportunity (read money-making opporutinty) whereby natural gas joule per joule is cheaper than oil. All that's required is to shift some of the demand from oil to natural gas.

I've been saying for some time that some enterprising auto or truck manufacturers will likely start to shift production of their vehicles to natural gas which is a drop in to existing fueling infrastructure (many gas stations already have natural gas pumps).

Now one of the major automobile manufacturers has released a natural gas powered version of their delivery vans (Daimler-Chrysler with their newly released natural gas powered Sprinter).

I expect other van manufacturers to soon follow suit. What this means is that we now have a second leg of the logistics delivery infrastructure shored up both by natural gas and battery electric.

Like I said before, I'll be ordering pizza from dominoes delivered by unconventional fuel powered vehicles while the doomers cower in their MRE filled basements awaiting the zombie apolcalypse.

Peak Oil? Yawn.

Peak Oil Specific Wind Intermittency Game Changer

Some German researchers have come up with an additional and novel way to store excess power from wind turbines when more power is being produced than can be absorbed by the grid: they convert it into natural gas. At a 60% efficient conversion rate with electric power already being 4X as efficient as fossil fuel we are looking at something very very interesting.

The full story is found at Science Daily.
Following are some selected quotes

ScienceDaily (May 5, 2010) — Renewable electricity can be transformed into a substitute for natural gas. Until now, electricity was generated from gas. Now, a German-Austrian cooperation wants to go in the opposite direction. In the future, these researchers and entrepreneurs would like to store surplus electricity -- such as from wind power or solar energy -- as climate-neutral methane, and store it in existing gas storage facilities and the natural gas network.
One advantage of the technology:it can use the existing natural gas infrastructure. A demonstrationsystem built on behalf of Solar Fuel in Stuttgart is already operating successfully. By 2012, a substantially larger system -- in the double-digit megawatt range -- is planned to be launched.

For the first time, the process of natural gas production combines the technology for hydrogen-electrolysis with methanisation. "Our demonstration system in Stuttgart separates water from surplus renewable energy using electrolysis. The result is hydrogen and oxygen," explains Dr. Michael Specht of ZSW. "A chemical reaction of hydrogen with carbon dioxide generates methane -- and that is nothing other than natural gas, produced synthetically."


The storage reservoir of the natural gas network extending through Germany is vast: It equals more than 200 terawatt hours -- enough to satisfy consumption for several months.

"The new concept is a game changer and a new significant element for the integration of renewable energies into a sustainable energy system," adds Sterner. The efficiency of converting power to gas equals more than 60 percent. The predominant storage facility to date -- pumped hydro power plants -- can only be expanded to a limited extent in Germany.

Starting in 2012, they intend to launch a system with a capacity of approximately 10 megawatt.
