2.5 hours. Additional features of the models will include a 100kW ePTO motor, a 25kW / 150kW ePTO plug. For the OEM’ s vocational Model 567 truck, specs call for a range of 100 to 250 miles.

Fuel-cell electric vehicles in the Peterbilt product line will have a range up to 450 miles and energy storage systems that include a 200-kWh battery and a 160-kW fuel cell stack. Refueling time is projected at 15 to 20 minutes.“ One key advantage of hydrogen fuel cell systems is their fill time,” Naik said,“ which will closely match what we have with diesel today.”

Naik also related that Peterbilt has fuel agnostic platforms in development.“ PACCAR and Cummins are both working on next generation internal combustion engines that will be capable of using hydrogen as a fuel,” he explained further.“ This technology is a zero-carbon solution, and even though CARB is currently focused on NOx, they have agreed to work with the EPA to

consider accepting this as a zero emissions solution.

“ Hydrogen internal combustion technology has many merits.” Naik added.“ These include a lower upfront investment and a familiar day-to-day usability that matches diesel, but like other technologies will require an intense effort to build out a hydrogen fueling infrastructure.”

Flexible Approach

Caterpillar is evolving our product portfolio for the future, noted Beth Hinchee, director emissions global regulatory affairs.“ All technologies have a place in the market with choices dependent on power, sector, region and application,” she said.“ Adoption will be driven by global investment, legislation and sustainability goals. Overall, the scope is large, complex and has many interdependencies so we are adopting a flexible solutions-based approach.”

Among the technologies Caterpillar is focused on include diesel engines, low

carbon intensity fuels such as hydrogen gas, battery electric systems, hydrogen fuel cells, hybrids and electric drives and integrated powertrains.

For heavy-duty off-highway applications, Caterpillar has announced the Cat C13D, a new 13-liter diesel engine platform. The inline, six-cylinder will offer eight power ratings from 456 to 690 HP and will meet emissions standards including EU Stage V and U. S. EPA Tier 4 Final, among others.

The Cat C13D engine platform enables the use of renewable liquid fuels such as 100 % HVO, B100 distilled biodiesel, and even up to B100 standard biodiesel. Its core architecture is designed for the future development of natural gas and hydrogen fuel capabilities.

Available for early OEM pilots in 2025 and scheduled for production in 2026, the Cat C13D engine is targeted for a wide range of off-highway equipment, including material-handling applications.
