A new fleet opportunity?

Natural Gas trucks are not new, but recent improvements in the technology and increases in diesel fuel costs have created renewed interest in these trucks. In addition to the potential cost savings, natural gas trucks can decrease GHG emissions which have become a goal for many fleets seeking to lower their environmental footprint. This webpage provides a basic introduction to natural gas, NG truck, fuelling, safety concerns, and the FortisBC NGT Incentive Program as offered in the Province of British Columbia.

What is it?

Natural gas or methane (CH4) has been used in homes for heating and cooking due to it being a safe and clean fuel. It makes for a similarly good motor fuel, albeit with one challenge: it has less energy per unit volume than conventional diesel.  In the table below the physical properties and application of compressed and a super-cooled liquefied NG formats are compared to diesel.
