Cummins Inc. is creating two hydrogen-fueled inner combustion engines which might be scheduled for manufacturing in 2027, however fleets and others are already signing up for them.
Cummins has developed engines for varied fuels — gasoline, pure fuel, propane, diesel — through the years, and its engines are utilized by all U.S. truck makers and others.
“That is simply the subsequent taste, hydrogen,” Jim Nebergall, basic supervisor of Cummins’ hydrogen engine enterprise, instructed Transport Subjects.
The 6.7-liter and 15-liter hydrogen engines goal a broad market: on-highway, development and agriculture; anyplace that has difficult obligation cycles, excessive gas consumption and high-capacity utilization, he stated.
“Hydrogen could have a dramatically decrease NOx stage than a diesel engine,” Nebergall stated, “however it is usually an enormous greenhouse fuel play.”
NOx (nitrogen oxide) is a generic time period for the nitrogen oxides which might be most related for air air pollution. These gases contribute to the formation of smog and acid rain, in addition to tropospheric ozone.
The phrase hydrogen is derived from Greek and means water maker. The byproduct a hydrogen ICE, or gas cell, produces is water vapor, in keeping with consultants. However what feedstocks are used to supply hydrogen gas decide its carbon depth.
That is very similar to with batteries and the supply of electrical energy to repower them — coal, pure fuel, wind, hydro. Consultants word the carbon and emission profiles of “clear” applied sciences can differ extensively.
With the hydrogen ICE, there’s a decrease buy value of the automobile in contrast with a gas cell-powered automobile or a battery-electric geared up for a 500-mile vary, Nebergall stated.
He famous virtually each main engine producer on the earth is taking a look at hydrogen for ICE.
“To me that’s only a signal of the seriousness of the expertise and the potential viability,” Nebergall stated.
Who’s On Board?
Corporations which have signlaed their readiness to undertake Cummins’ hydrogen inner combustion engines:
• Werner Enterprises Inc.
• Transport Enterprise Leasing
• Buhler Industries Inc.
Werner Enterprises just lately introduced it signed a letter of intent to buy 500 Cummins 15-liter hydrogen inner combustion engines once they change into obtainable.
Werner ranks No. 17 on the Transport Subjects High 100 checklist of the biggest for-hire carriers in North America. It has about 8,800 tractors. The corporate additionally plans to validate the Cummins 15-liter pure fuel engine together with the X15H,. Each are a part of Cummins’ new fuel-agnostic engine platform.
Omaha, Neb.-based Werner’s said purpose is to cut back GHG emissions 55% by 2035.
“Our prospects are displaying elevated curiosity in additional sustainable decisions within the market,” Chairman and CEO Derek Leathers stated in a launch. “We see important potential in using Cummins’ fuel-agnostic engine platform to proceed the momentum towards lowering our carbon footprint.”
TEL, a industrial truck and trailer tools lease and remarketing supplier, reported it can combine the X15H engines into its leased fleet of professional quality vehicles.
Tractor maker Buhler has used Cummins’ engines solely in all four-wheel drive tractors since 1967, and new low- and zero-carbon options are ideally suited to farming, the corporate famous.
Potential prospects know how you can work on an ICE engine, Nebergall stated, so the dialog rapidly turns to “the place the hydrogen gas is on the market, what does the gas infrastructure seem like.”

Federal cash is pouring into the area by the Inflation Discount Act to drive down the price of hydrogen gas and supply different incentives for constructing stations, creating hydrogen hubs and associated manufacturing. The engines and gas cells are being readied as is the technique of storing gaseous or liquid hydrogen on board vehicles.
Hydrogen could be bodily saved as both a fuel or a liquid. Storage as a fuel sometimes requires high-pressure tanks (5,000–10,000 kilos per sq. inch tank stress). Storage of hydrogen as a liquid requires cryogenic temperatures as a result of the boiling level of hydrogen at one ambiance stress is minus 252.8 levels Celsius (or minus 423.04 degreesFahrenheit), the Division of Power reported.
On this particular version of RoadSigns, hosts Seth Clevenger and Mike Freeze present an inside have a look at Transport Subjects’ 2022 High 100 Non-public Carriers checklist. Tune in above or by going to RoadSigns.ttnews.com.
The identical Kind 4 carbon fiber gas tanks used for pure fuel could be used for hydrogen, Nebergall stated. The one distinction is the storage stress, which implies there are thicker-walled tanks wanted for hydrogen.
“The entire security exams they need to undergo are frequent with pure fuel storage,” he stated.
With liquid hydrogen, a truck may prolong its vary.
“It’s one thing we’re watching very intently,” Nebergall stated. “I feel it will likely be very attention-grabbing to see which of these two applied sciences win and the place they apply.”
He stated fueling stations must ship each, and that’s a problem, too.
“However it is extremely a lot in play. I don’t suppose we’ve got a prediction on a winner,” Nebergall stated. “I feel [gaseous and liquid hydrogen] could have a spot. It’s actually concerning the onboard storage and what will likely be there on the time.”
In the meantime, Cummins is closely investing in hydrogen gas cells, he stated, as one other viable resolution for the industrial sector.
Cummins introduced in Might it can provide Class 8 market chief Freightliner, a model of Daimler Truck North America, with a Cummins hydrogen gas cell powertrain for Freightliner’s heavy-duty Cascadia mannequin. Items will likely be obtainable for choose prospects by 2024.
Cummins reported it spent $1.1 billion in 2021 on analysis and growth, practically doubling its earlier finances, and most was for its decarbonization technique.
