    Cummins New Hydrogen Combustion Engine Platform Takes On Diesels

    This was sent to us, and we would like to hear everyone's thoughts on this.

    ---



    With the onslaught of electrification and battery-electric vehicles (BEVs) in the works, many have predicted the end of internal combustion engines. But some manufacturers are taking a different approach to reducing the greenhouse gas effect by using hydrogen as an internal combustion engine fuel.

    Cummins announced two new hydrogen variants based on a new fully fuel-agnostic platform. Above the head gasket is where components change, depending on the fuel type. Below the head gasket will be a short-block common across the variants.

    In Japan, for example, a consortium of OEMs including Mazda, Yamaha, Toyota, and Kawasaki has banded together to develop hydrogen solutions for ICE. Meanwhile, some companies, including Cummins, have jumped into the hydrogen mix in North America. Cummins recently announced that it is testing two hydrogen-powered variants for medium- and heavy-duty markets.

    Cummins believes that the transportation industry should develop multiple solutions to meet the demands of on- and off-highway uses due to the wide variation in applications and operating environments. BEVs are thought to be impractical for many of these heavy-duty applications. This is where hydrogen may be the more practical choice for OEMs in the future.

    The transportation industry is adding the most carbon emissions to the atmosphere. Cummins believes it can scale up hydrogen combustion engines by decade's end.

    Zero Carbon

    Last July, Cummins announced that it was dipping a toe in the water and testing hydrogen internal combustion (ICE) technology. Since then, the company has achieved power and torque targets (over 810 lb-ft torque and 290 horsepower from the medium-duty engine with aims of 500 horsepower and more than 1,000 lb-ft of torque for newer prototypes). Remember that Cummins has a significant global manufacturing footprint, so the company can quickly scale production once the bugs are worked out.

    The engine platform will be a "zero-carbon fueled solution for multiple markets," according to Cummins. It intends to produce hydrogen internal combustion engines in both 15.0-liter and 6.7-liter displacements, believing that these engines are the market's sweet spot and will allow it to take action and reduce greenhouse gas emissions in this decade.

    Hydrogen-combustion engines can be implemented with a lower initial cost than a hydrogen fuel cell or BEV, with only minor modifications to today's vehicles. OEMs entering the hydrogen-combustion market may also benefit from the early adoption and scale of hydrogen-powered vehicles, as features such as extended vehicle range, fast fueling, powertrain commonality, and user familiarity attract customers.

    "Heavy-duty trucking is critical to the global economy and is one of the hard-to-abate sectors of the economy." — Daryl Wilson, Executive Director of the Hydrogen Council.

    "We are encouraged by progress at Cummins in the development of hydrogen-fueled internal combustion engines and look forward to continued advancements that can help us reach cost-effective decarbonization of economies worldwide," says Hydrogen Council's Executive Director Daryl Wilson

    Cummins is betting on hydrogen combustion in the short term because medium- and heavy-duty applications are much more likely to switch to this fuel when it is available. In the coming decade, buses and long-haul trucks running on hydrogen will become a common sight, according to Cummins. If hydrogen can grow in this market and be a fuel of choice for heavy-duty customers, Cummins believes it will be complementary to battery-electric buses and trucks that are economically and operationally viable for certain applications.

    Other applications such as construction equipment, agricultural machinery, and even ships may join the hydrogen engine mission soon. These are most likely applications that are hard to electrify due to their usage demands, and already have variants powered by various gaseous fuels.

    The black valve cover and "X15N" marking indicate this X15 engine is configured for natural gas operation.

    RAM Tough?

    A hydrogen internal combustion engine will both physically fit in today's trucks and work with current transmissions. They will also integrate seamlessly into the industry's existing service networks and practices. For fans of RAM trucks, the 6.7L Cummins hydrogen engine would fit neatly into one of their heavy-duty pickup models. And it appears that Stellantis is bullish on hydrogen, too, as it has alluded to running this fuel as soon as 2024.

    Cummins plans to use its new fuel-agnostic engine platform to help develop hydrogen combustion engines moving forward. The 6.7-liter and 15-liter will have optimized cylinder heads with flexible overhead cam systems that can be swapped, depending on the fuel used (i.e., natural gas, diesel, or hydrogen). The hydrogen-specific heads will offer improved cooling and reduced friction to achieve a more efficient and higher power density from the platform. The changes between fuels will, in theory, only change above the head gasket.

    According to Srikanth Padmanabhan, president of Engine Business for Cummins, there were too many limitations and other compromises associated with converting a diesel or natural gas engine over to hydrogen, so a new platform was necessary.

    "[We] have designed an advanced optimized combustion chamber for fuel mixing, charge motion, and turbulence generation that we believe is critical for fast hydrogen combustion to maximize power density and efficiency," Padmanabhan explains. "It's also important to note that this combustion system will synergize with our next-generation high power density, high-efficiency natural gas engines."

    CNG Experience

    With decades of experience with natural gas-powered engines, Padmanabhan adds that Cummins is primed for the challenge of hydrogen ICE as the industry shifts to zero-carbon.

    Cummins is currently testing prototype hydrogen engines with the goal of 500 horsepower and 1,000 lb-ft of torque for the heavy-duty segment.

    "Launching the hydrogen engine also benefits other paths to reach a zero-carbon future, such as hydrogen fuel cells," he says. "By creating a viable use case and demand for hydrogen in the near term, we can accelerate hydrogen infrastructure build-out and increase scale production of vehicle storage tanks. Both advances are necessary for the widespread adoption of fuel-cell powertrains."

    Jim Nebergall, General Manager, Hydrogen Engines at Cummins, says their customers have positively responded to this new initiative because the hydrogen ICE platform is based on familiar componentry. "These engines look like engines, sound like engines, and fit where engines normally fit."

    In May, the company debuted its 15-liter hydrogen engine at ACT Expo in Long Beach, California. It will be built on its fuel-agnostic platform, where the engines use similar components below the head gasket. Above the head gasket, each has different features for the different fuel types. The 15-liter version is expected to be in full production in 2027. The 6.7-Liter engine could be in production as early as 2023-'24.

    Interesting.

    I guess we will have to see how things work out and what the costs will be to own one.

    Re: Cummins New Hydrogen Combustion Engine Platform Takes On Diesels

    Every time hydrogen was introduced as a possible fuel alternative; the Hindenburg disaster was brought up as a reason not to invest further in it.

    Cummins has been advertising advancements in hydrogen for a while now.

    I’m glad to see it actually get some traction.

    Hydrogen is around three times as expensive as gas per energy content unit.

    Reports I’ve read say by 2025, it should be cheaper option than gas.

    I’m not sure I believe that.

    Hydrogen embrittles certain metals I wonder what life span and cost of engines will be or if that is not a issue at all in the engine.

    I’m not against alternatives to diesel or gas at all.

    I bought my wife a Tesla, and I freaking love it.

    I drive it more than she does.

    I firmly believe any one who drives one would love it as well.

    Even those who say, “I have to hear the sound”

    One thing I would like to see advance is nuclear.

    Both in transportation and grid electricity.

    You really can’t say you are for green energy and rule out nuclear.

    While unlikely in cars/trucks due to the containment requirements, a tiny cell reactor size is way too big to fit in a car.

    Could you imagine going years without refueling?

    I’ll take one and be the first person to throw a big turbo, stack out of the bed, and figure out the failure levels of things like the head gasket, how much RPM it wants to turn, etc.

    Like it or not, the future is now.

    This is the next thing.

    In 30 years, we’ll be recalling the moment when the first hydrogen ram 3500 came out, and our current trucks will be more of a “back in my day, these things blew black smoke” kinda ordeal to our great grandkids.

    My thought is: that the gov. will force a complete nontamper lockdown on the electronics, etc., to keep us from toying with vehicles.

    It is rarely about the environment anymore, so it is about control.

    Re: Cummins New Hydrogen Combustion Engine Platform Takes On Diesels

    I embrace technology and progress as long as it makes sense and is an improvement.

    This has alot of bugs to be worked out, but I don't see the improvement in many ways.

    Reliability and longevity need to be proven for me to embrace it.

    The biggest problem is the fuel itself.

    While transferring hydrogen from tank to tank, the flow can cause a spark if not done correctly, which is why it failed in California many years ago.

    Companies won't be able to train the average driver to fuel up one of these trucks.

    Thus another expense and employees just to fuel trucks.

    With the labor market the way it is now, good luck with that.

    I will tell you from the behind-the-wheel perspective that these engines will be gutless compared to what we have now.

    Torque is a significant number for big rigs; they are talking about an X15 putting out 500 hp and 1000 lb-ft of torque.

    The current X15 is 1600-2000 lb-ft of torque, depending on the configuration.

    The reality of a truck with this type of power being out in real-world traffic will be a nightmare.

    Yeah, the fuel transfer for hydrogen is an issue.

    Another issue currently is supplied.

    You need to be able to buy it.

    The biggest hurdle with using hydrogen to power trucks is the same as using natural gas.

    You’d need a huge tank to store hydrogen in the gaseous form if you want to go any distance. It can be liquified, but you must keep it cold at -423F.
