What about the Pickens Plan?

The good news about electricity as a transportation fuel for cars is finally breaking through to the mainstream. GM’s centennial celebration in mid-September saw the unveiling of the production version of the Chevrolet Volt, still scheduled for appearance in showrooms in November 2010. Hundreds of articles were published asking if the Volt can save GM. GM’s bad boy Bob Lutz even appeared on the Colbert Report, to mixed result. (Video embedded below post.) Other automakers are watching closely, with announcements heralding their own electric intentions.

Hydrogen and fuel cells remain decades from meaningful deployment, even their supporters concede. For the foreseeable future, ethanol remains dependent on corn. Meanwhile, in a back to the future moment, T. Boone Pickens is spending tens of millions of dollars promoting CNG (Compressed Natural Gas) as the bridge fuel to get the U.S. off petroleum in the short term. If it were 1976, he would be right.

The Arab oil embargo and price increases of the ‘70s pushed the U.S. away from using petroleum to generate electricity. Today, less than 2% of American electrons are produced with oil. Diverse, American sources of energy have made the electric grid essentially resilient and secure, immune to petroleum’s price volatility or politics.

For reasons political and economic, cars and trucks and busses remained tethered to petroleum. Before greenhouse gasses became a global concern, before we came to terms with the inevitable limits of fossil fuels, natural gas would have been a logical fuel alternative to petroleum. Had national and economic security trumped the power of oil and auto companies, a large percentage of cars would run today on cleaner, cheaper, domestic natural gas. A few billion dollars a week wouldn’t leave the country, and we would all understand the value of choice.

But we find ourselves in 2008. While less polluting than petroleum, burning natural gas emits significant carbon. Natural gas, like petroleum, is not forever. And today natural gas is a critical fuel for electricity generation. And making electricity is simply a more efficient use of this resource. As Joe Romm wrote at his Climate Progress blog:
We currently use natural gas to produce 22% of our electricity.” Most of that electricity comes from gas burned in combined cycle gas turbines at an overall efficiency of up to 60%. Why in the world would the federal government — or anyone else — spend billions and billion of dollars on natural gas fueling stations and natural gas vehicles in order to burn the gas with an efficiency of 15% to 20%? Natural gas is simply too useful and expensive to squander in such a fashion.
Pickens’ plan includes lots of wind-generated electricity, ostensibly to replace the natural gas he would divert to vehicles. One can’t, however, simply replace gas generation with wind. But we can use the electricity generated with each to power plug-in cars.

Pickens plan can be viewed as a logical criticism of Al Gore’s plan for 100% renewable electricity within ten years because it doesn’t do anything about our petroleum dependence. Gore’s group’s TV ads, (almost as ubiquitous as Pickens’,) have recently begun to mention petroleum addiction but still offer no solutions.

To the plethora of petroleum alternatives served up during the past few years – hydrogen, fuel cells, biodiesel, ethanol, electricity - Pickens’ plan resurrects the fuel discarded since 2000 by Ford, GM and Toyota. As if Americans weren’t confused enough already. The truth remains vehicles are electricity’s killer app.

You see the same hole in the Pickens plan that I do. All of that extra wind generated electricity is not going to put much of a dent in the electricity generated by natural gas. I don't see many of the existing fossil fueled power plants being shut down any time soon.

A much better use for the wind generated electricity is to directly power transportation. Electric cars are the better way to utilize the extra energy. The net result is the same, less oil will be used.

CNG cars still pollute and like others have said "it's easier to clean up 100 smoke stacks than 1 million tail pipes".

CNG is a great way to eliminate oil usage; any car or truck can be converted to CNG. CNG is a clean fuel (you get HOV stickers just like an EV) and it's plentiful and there's already a fueling infrastructure. It's proven and cheap.

EVs and rooftop solar power are better!

But for those who believe in Fuel Cells and the Hydrogen Hype, just ask yourself: why not CNG? It only takes 3600 psi, not 5000 or 10,000 psi; it's much cheaper than H2; it doesn't require a fuel cell stack that costs more than a car and only lasts 3 years; and so on.

While CNG isn't perfect, it's a LOT better than using imported oil.

Did you know that the tar sands of Canada use "free" natural gas to boil the heavy oil out of the shale? And that the amount of natural gas used would take a CNG car farther than the REST of the oil produced takes the average oil-fired car? Of course, the electric used would take an EV two or three times as far! So EVs are best, but CNG isn't a bad idea.

Solar rooftop power is best, because we don't need to desecrate teh wilderness to build solar plants; the rooftops of America, more than 10,000 square miles, have more than enough sunny acres to power ALL our electric needs, even if all cars are plug-ins.

And rooftops are already developed, no new destruction needed. And the solar panels cool and protect the roof, and the electric is generated where it's needed and when it's needed.

Where are electric cars used today? Is the project still in progress or what happened to it?
