A Compressed, Natural Alternative at the Gas Pump

A Compressed, Natural Alternative at the Gas Pump

On America's roads, we're seeing a lot more big vehicles, like buses and trucks, that run on Compressed Natural Gas (CNG).  So why don't we see any passenger cars run on the same fuel? Because natural gas needs to be extremely compressed in order for us to use it, we need HUGE gas tanks, and they are too big to fit into most cars.  In other words, the tank needs to be shrunk. One company is working on doing just that.  Instead of compressing gas, they discovered that more gas can be stored if there are more surfaces for the methane molecules to attach to.  The researchers are working on developing a cyrstal-like material, called NuMat, that can be placed inside small tanks.  They say that just a gram of the material has the same surface area as a football field! The company is still young, but they feel they are well on their way in their mission to move the Planet Forward.  In fact, the U.S. Department of Energy agrees -- they awarded NuMat a $1.5 million grant!
