When faced with the obstacles of added costs and lack of infrastructure to accommodate concentrated natural gas (CNG) vehicles, John Sheehy, CEO of Sheehy Mail Contractors, decided to make such a conversion in favor of going green and reducing fleet emissions for their 100 trucks.


Serving the U.S. Postal Service for years as an expert in efficiency, Sheehy realized that to make CNG viable, it would require innovative ideas such as those of Todd Fowler, Founder and CEO of Commercial Hydrogen, Inc. Now, over 90 vehicles of 100 in their fleet have converted to CNG that now outperform their initial diesel counterparts. Though it is notable, diesel trucks weren’t outperformed for long since discovering the same retrofit of introducing hydrogen to the system. The introduction of hydrogen to the diesel trucks has reacted in the same way that CNG vehicles had.


John Sheehy goes on to say, “We are a leader in clean transportation and have converted over 90 trucks of 100 in our fleet to clean-running CNG fuel. One of the issues with CNG is it typically gets 11% lower mileage than its diesel counterparts (which average 7.2 mpg). Commercial Hydrogen has helped solve that problem with the additional mileage that the Hydrogen system gives our trucks. The system is compact and highly customizable for our operation.”


Until now, this was among few faults in CNG systems, considering the greatly lowered emissions and cleaner-burning properties of natural gas. This also means lowering the impact on the environment, the impact to an owner/operator and enterprises alike could be a lot greater—not just in fuel savings, but also in maintenance costs. Considering maintenance on large vehicles gets rather pricey. Any way to lower those costs and keep the vehicles on the road in working order for as long as possible is essential to operations and overhead of any owner/operator or company.


Though CNG is to be a clean-burning alternative fuel, the addition of hydrogen, which burns up to 15% greater in comparison, allows the engine to run longer and more efficiently overall, without the residue and buildup of other fuels that burn much more inefficiently. The result is an engine that can run for a longer time without regular maintenance as often, and thus, as costly.


Commercial Hydrogen Board Member, Troy Bohlke, says, “We firmly believe that the trucks that need fuel savings the very most are those trucks in daily use today. Since Commercial Hydrogen is a retrofit technology that can be installed today on virtually any semi-truck on the road, it is positioned to make the biggest impact on the economy of the U.S. trucking industry.”
