Peterbilt previews PACCAR’s hydrogen internal combustion engine powertrain

The decarbonization potential of hydrogen-fueled powertrains in the heavy-duty trucking Industry.

“Not a one-size fits all solution.” That’s a mantra of the heavy-duty trucking industry where equipment has been and will be built to spec. Application drives equipment decisions. Yet somehow that idea gets lost when we’re talking about zero-emissions vehicles.

Maybe it’s because today’s battery electric trucks are “simpler” in terms of hard-part components that we paint future powertrains with a broad brush. Or maybe it’s that OEMs, suppliers and fleets are taking zero-emission equipment possibilities seriously and finding out that the tried-and-true, purpose-built ethos of trucking equipment will continue in the zero-emissions age.

Enter hydrogen internal combustion engines: a technology with growing potential as a decarbonization option. Peterbilt showed off a hydrogen-fueled PACCAR engine outfitted in a DAF truck in its booth at ATA’s MCE, and we caught up with Jacob White, product marketing manager, to talk details.

“This hydrogen internal combustion engine uses hydrogen as a fuel, not unlike a natural gas-powered unit today, and it produces zero carbon,” he said. “This is a zero-carbon emission solution and a simple aftertreatment system. It should be a relatively similar experience to running a truck that our fleets are used to today.”

While it boasts zero carbon emissions, there are some caveats to the technology, as well as more potential benefits. For the full details, watch the video above.

If you’ve been on the internet in the past year - and I’m going to go ahead and assume that you have - you’ve probably heard entirely too much about AI. Artificial intelligence has been a concept in computing for decades and decades, but use of the term really multiplied with the release of generative AI programs like Chat GPT. It’s got everybody talking about AI, and everybody wanting to release products that heavily feature AI.
