Natural gas provides economic benefits over diesel - experts

HOUSTON (ICIS)--As natural gas takes a larger role in the global energy sector, environmental benefits are factors driving compressed natural gas (CNG) and liquefied natural gas (LNG) in diesel fuel displacement, industry experts said on Thursday.

CNG and LNG can lower emissions by 40% of carbon dioxide (CO2), nitrogen oxide (NOX) and particle mass, said Peter Evans, director of global strategy and analytics at General Electric.

“There’s some very significant drivers for that consideration; there’s a lot happening in terms of evaluating and investing today for natural gas fuelling in transportation,” said Robert LaCount, executive vice president at MJ Bradley and Associates.

The speakers made their comments during the NABE Industry Conference held by the National Association for Business Economics (NABE).

However, LaCount cautioned that while CNG and LNG have significant benefits over diesel, “diesel has come a long way in reductions and fuel economy”.

“There is some benefit going from new CNG instead of new diesel, but as you can see, there’s not a significant reduction. There’s certainly more in this case with existing diesel,” he said.

He added: “It’s not a significant case in reduction like you see in replacing coal with natural gas. It’s a much finer line than that.”

Still, today’s engines have the capability to handle natural gas as fuel, he said. The question is whether the US can get the natural gas fuel where it is needed.

LaCount said that the top six states with existing and proposed natural gas for fuel are California, Texas, Arizona, Utah, Alabama and Idaho.
