Boone Pickens has been advocating for months. While I’m not convinced the natural gas vehicle market will ever take off outside of enterprise fleets, trucks and buses, natural gas vehicles could play a significant role in cutting carbon emissions. Here’s how the economics of natural gas vehicles works. [...]

In my country in the past 10 years THOUSANDS of cars have been successfully converted to Natural gas and LPG. It’s not difficult at all. The only problem is with older engines: natural gas it’s too cold (colder than LPG) and can break plastic or rubber parts, including pipes. In fact, it’s almost impossible to find a taxi or fleet vans working on gasoline! Even 4x4s. In march 2010 there will be a new public bus system for Lima and all the buses have been specially made to operate on natural gas. At first, this was problematic for the lack of suppliers, but now it’s OK. The design was made here and the manufacturing in China…(it was the only cheap alternative). Let’s see the outcome.

Vinod Khosla is wrong about most energy issues. India is a huge user of NGVs! What DOES he believe in? Cellulosic ethanol? Good luck hauling all that bulky feedstock to the multiple, expensive refineries needed.

New storage technologies for NG include charcoal briquette-like substrates that allow for good storage volumes at a few hundred psi. That’s a low enough pressure to allow for conformal tanks, which improves storage efficiency.
