"Heavy-duty Truck"

At the turn of the twentieth century, Theodore Roosevelt became the 26th president of the U.S. and a few years later Henry Ford debuted the Model T in Detroit, Michigan. Only few visionaries at that time may have imagined a future with an intricate highway system, carrying people and goods from one coast to another in a matter of days. Or trolleys and streetcars becoming massive urban busses, runn

When it comes to natural gas engines, there are a range of frequently asked questions about the cost, practicality, and feasibility of integrating natural gas into commercial fleets. There are certainly preparations that need to be considered, but the learning curve to implement natural gas engines is not as steep as people may think, especially in comparison to the benefits of natural gas in tran

From tractor trailers and transit buses to delivery trucks and terminal tractors, fleets have traditionally relied on diesel engines to provide the torque, reliability and durability needed by heavy-duty commercial applications. Natural gas engines, however, have emerged as a great alternative to diesel. Drivers, mechanics, and fleet managers appreciate natural gas engines for a variety of reasons

Commercial vehicle fleet managers face a dizzying array of options when it is time to replace or upgrade vehicles. One question that fleet managers often ask is whether there are any good fuel options available to their business besides diesel or gasoline. Alternative fuels, including natural gas, have grown in popularity in recent years due to their broad appeal. Considering a full or partial swi

The advent of the hydrogen economy infrastructure has been hyped for a long time. In 1997, Wired magazine was writing about the “Dawn of the Hydrogen Age”. Cars with solar panels on their roof would go 5,000 miles between fill ups—and you would be able to drink from their exhaust. By the early 2000’s, several car manufacturers in the world had a hydrogen car program, few with hydrogen engines; unf

Today, internal combustion engines have economies of scale due to their popularity across trucks, buses, construction, and agriculture equipment. As these engines start to use low to zero carbon fuels, they can reduce emissions while also taking advantage of their existing scale.   This combination of economies of scale and reduced emissions help original equipment manufacturers (OEMs) and

The transportation sector emits five million metric tons of CO2 a day in the U.S. This is about 36 pounds of carbon every day for each person in the U.S.  Passenger cars, motorcycles, heavy-duty trucks, trains, boats, and airplanes all contribute to this carbon emission, but at varying levels. When you look at the increased greenhouse gas (GHG) emissions among these transportation applicat

Regulations limiting greenhouse gas emissions (GHGs) from motor vehicles are tightening around the world. With this, both hydrogen engines and hydrogen fuel cells are receiving an increasing interest.  Given medium and heavy-duty trucks are a major source of CO2 emissions, the transportation sector’s journey to destination zero features both technologies. As more truck makers join the

For a long time, it looked like cars with hydrogen engines or fuel cells would one day take over the roads and the transportation sector. Hydrogen fuel cell cars release no harmful emissions of any kind, have a long range, and can be refueled in minutes. In theory they sound like a great way to decarbonize the transportation sector. In practice, hydrogen cars are facing stiff competition from plug

  How can hydrogen fuel power a vehicle? Using hydrogen to power an engine or motor is more straight forward than you might think. There are two ways to do this.  The first way involves a device known as a fuel cell. The fuel cell converts hydrogen to electricity, which then powers the vehicle’s electric motors, just like in any electric vehicle.  The other way is hydrog

Cummins Inc. (NYSE: CMI) today announced that it will bring to market a 15-liter natural gas engine for heavy-duty trucks. The 15-liter natural gas engine is an important part of Cummins strategy for its path to zero emissions to go further, faster to reduce the greenhouse gas and air quality impacts of its products in a way that is best for its customers and all stakeholders.  The strateg
