Wanted: An engine technology that best adapts to natural gas
Although I have written back and forth with Hugo Tour (left in photo, with Oded, his son, on the right) on a number of occasions, I finally met him in person at the 2012 SAE World Congress in Detroit. I’m honored to say that he emailed me today and assured me that my support of the vision of the split cycle engine technology is still founded on practical design and concepts. For ref, read - Tour Engine Prototype 2 operational before SAE World Congress.
First things first, though. The Wall Street Journal (WSJ) article, "America, Start Your Natural-Gas Engines" struck a chord with Hugo Tour. It stated how the recent deluge of low-cost shale gas is already changing the way the country views this energy resource.
While electric utilities are turning to gas to power their turbines, truck carriers are investing in conversion for the big rigs, and many chemical companies that rely on the fuel are coming back to America after years of investing overseas.
In my own view, if America fails as a nation to take advantage of natural gas, those gas reserves will most likely be sold elsewhere. No wonder the old adage that America too often starves with two loaves of bread in its hands seems so true, especially when we apply it to energy resources.
According to the WSJ, “Every day, we consume 70% of our oil getting from place to place—and produce more than 30% of our greenhouse gases along the way. If we could run our vehicles on natural gas, it could kill two birds with one stone: Not only is natural gas a lot cheaper than oil right now, but its emissions are much cleaner than gasoline or diesel.”
Of course, there are infrastructure challenges, but not insurmountable as people think. The WSJ did state that public refueling stations are few and far between; and that is true. However, in my view, that is changing with the increasing number of stations along the interstates which will feed the fuel for the big rigs that convert.
In praise of the WSJ article, I like the idea that it didn’t hold back. Author, Tom Fowler, is to be commended for being bold enough to lay out all sides, a rare trait in a world where shades of green and the press contend with anything with fossil remains in it.
While natural-gas cars are indeed more expensive than gasoline models, sometimes to the tune of thousands of dollars, be apprised this is without government subsidies of the same magnitude as EVs. Trucks, on the other hand, have the advantage of writing off the expense as a business deduction; and they withdraw most from our oil supplies.
The WSJ stated the only natural-gas passenger car sold in the U.S., the Honda Civic GX, costs about $5,200 more than a comparable gasoline vehicle and $3,600 more than the gasoline/electric hybrid Civic. I have to ask: Why so much?
