Hydrogen retro fit and semi retro fit diesel motors

[freds]

Hydrogen is coming but it is going to take a few more years ,all the diesel engine manufactures are on board CAT has been on board for past 10 years Reading the CAT magazine they expect to double the life of their engines using Hydrogen fuel to over 40,000 hours  before needing a rebuild they are about 20,000 hours now on diesel fuel

At least a decade or two assuming they can find white hydrogen from gas wells. They are very much looking and there's a couple of wells in Europe. But a better use would be steel making.

Then we have to wait for trickle down before it's affordable for us. Even if Greyhound went to Hydrogen tomorrow the used buses to convert wouldn't be available for a decade afterwards.

ULEMCo Secures Funding to Scale Zero-Emission Hydrogen Conversions for Heavy-Duty Fleets
ULEMCo Secures Funding to Scale Zero-Emission Hydrogen Conversions for Heavy-Duty Fleets
November 6, 2025 0 By Jake Martin

ULEMCo Ltd has revealed they've just locked in a fresh round of funding to kickstart their first purely zero-emission technology offerings for heavy-duty commercial vehicles. This Liverpool-based clean-energy pioneer—founded in 2014 to turn decades of know-how in hydrogen combustion and fuel cell technology into real-world solutions—is steered by Managing Director Amanda Lyne, a 20-year veteran of the hydrogen world, alongside Non-Executive Chairman Dr. Robert Joyce. Over the last year, they've been fine-tuning their dual-fuel conversion kits and pushing full-hydrogen systems forward, all aimed squarely at the toughest challenges in industrial decarbonization: heavy trucks, refuse vehicles, gritters and sweepers.


Transport makes up roughly 25% of the UK's carbon footprint, and when it comes to heavy-duty work—like long-haul regional routes or snow-clearing fleets—battery-electric solutions can really hit a wall under heavy torque demands and marathon driving distances. ULEMCo's clever dual-fuel approach and longer-term bet on pure hydrogen engines are designed to bridge that gap, slashing up to 70% of tailpipe CO₂ today and gearing up for 100% green hydrogen operation in just a few years.

If you're a fleet manager juggling refuse collection routes, winter maintenance or regional haulage, you know how painful downtime and complex refuelling schedules can be. What you need is something that slides right into your current depots and keeps trucks rolling—without a complete overhaul of your operation.
ULEMCo's retrofit kits bolt onto existing diesel engines, swapping in hydrogen for up to 70% of the fuel mix, while keeping the diesel backup ready for remote runs or service stops.
         ***
Key Takeaways
Funding unlocked: New cash injection fuels deployment of hydrogen dual-fuel and full-hydrogen conversion kits.
Immediate impact: Dual-fuel systems replace 30–70% of diesel with hydrogen, cutting CO₂, NOₓ and particulate pollution.
Future-proof tech: Full-hydrogen combustion engines and fuel cell technology modules aim for genuine zero-emission performance.
Infrastructure synergy: Partnerships with UK hydrogen hubs strengthen hydrogen infrastructure and streamline depot refuelling.
       ***
Net-zero alignment: Supports the UK's 2050 goals and accelerates the growth of the green hydrogen market.

How the Hydrogen Dual-Fuel System Operates
At the heart of ULEMCo's kit are high-pressure hydrogen cylinders, custom injectors and a revamped electronic control unit tucked neatly under the vehicle. The magic happens in the combustion chamber: diesel and hydrogen blend at a programmed ratio—anywhere from 30% up to 70% hydrogen—so you keep the torque you need while cutting CO₂ emissions in step. Best of all, the original diesel setup stays intact. If you're rolling through a corridor with limited hydrogen infrastructure, you can switch back to diesel-only mode at the flick of a switch.

Installation is surprisingly quick—around two to three days at a certified workshop or even on-site at your depot, depending on truck size. ULEMCo's team handles calibration, safety protocols and training for your in-house mechanics. Their modular design means you can scale or update kits as hydrogen supply grows and government incentives evolve...

Hydrogen Fuel Cells Drive Daimler Truck's Zero-Emission Strategy for Europe's 6 Million Trucks
November 28, 2025 0 By Tami Hood
For Karin Rådström, CEO of Daimler Truck AG, it's simple: Europe's highways should hum with zero-emission technology. Whether you're talking hydrogen fuel cells or battery-electric powertrains, her mission is to decarbonize around six million trucks plying the continent today. Under the "Stronger 2030" banner, Daimler Truck is doubling down on ambitious sustainability goals while keeping an eye on profitability—proving you don't have to sacrifice the bottom line to save the planet.

Heavy-duty transport eats up a big chunk of Europe's transport emissions. With around six million trucks on EU roads, the diesel era can't hang on much longer. Europe's regulatory push—from tighter emission rules to subsidies for clean vehicles and backing new hydrogen infrastructure—coupled with a broader drive toward sustainable energy and industrial decarbonization, lays the groundwork. Yet, trucking needs vary: the range, payload and duty cycle of a long-haul hauler aren't the same as those of a city distribution rig.

Karin Rådström makes a clear case for mixing and matching technology: battery-electric trucks where you've got charging stations and shorter hops, and hydrogen fuel cell vehicles when you need longer range, heftier loads and lightning-fast refuels. That technology-neutral playbook lets fleet operators pick the right tool for each job, smoothing the way for a broader move to zero-emission technology.

The case for a dual-track approach
The beauty of running two paths in parallel is flexibility. Battery-electric powertrains excel in regional haul, urban delivery and return-to-base operations—where high-capacity charging is already sprouting up. Meanwhile, hydrogen fuel cells, like those in the Mercedes-Benz GenH2 prototypes, deliver 600+ kilometers ( 374 miles ) of range, handle heavy payloads and refill in minutes. By backing both camps, Daimler Truck protects customers from bumps in the infrastructure rollout and keeps fleets moving.

Fuel cells vs. batteries: picking your haul
Think of battery-electric trucks as the go-to for routes with RELIABLE overnight charging or fast-charging corridors. They're super-efficient, emit zero tailpipe pollution and ride on a grid that's steadily greening. On the flip side, hydrogen fuel cell rigs thrive when you can't afford long charging stops and need to cover vast distances. The only emission? Water vapor—making them a poster child for industrial decarbonization in demanding long-haul work.

...What is Clean Truck Check?
Clean Truck Check is an initiative from the California Air Resource Board (CARB) that requires heavy-duty vehicles that travel in the state of California to regularly submit electronic emissions inspections. This includes both in-state and out-of-state vehicles that operate on California public roads.

More formally called Heavy Duty Inspection and Maintenance (HD I/M) — Clean Truck Check is an emissions-reduction program for diesel and alternative fuel heavy-duty vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds. HD I/M applies to the trucks, buses, and motorhomes that create a majority of the emissions on the road.
Clean Truck Check Exemptions
Although most heavy-duty vehicles must abide by the CARB Clean Truck Check, some are exempt from the program.

The following vehicles do NOT need to meet these emissions requirements:

Zero-emissions vehicles

Authorized emergency vehicles

Military tactical vehicles

Motorhomes registered outside of California

Historical vehicles

Vehicles operating under an experimental permit

New vehicles with engines certified to the most stringent NOx standard (less than or equal to 0.01 g/bhp-hr)

Gasoline vehicles

Toyota Powers Up California's Hydrogen Infrastructure with FirstElement Fuel Investment
December 15, 2025 0 By Tami Hood

Wondering how to break the chicken-and-egg cycle of hydrogen adoption for heavy-duty fleets? Toyota Motor North America has stepped up with a big move, announcing a strategic investment in FirstElement Fuel Inc. The goal? Beefing up California's sprawling network—92 fueling spots across 38 locations—and supercharging the hydrogen infrastructure that keeps fuel cell electric vehicles on the road.

Scaling Up the Station Network
FirstElement Fuel has been in the driver's seat since 2013, rolling out stations from Irvine and Santa Ana down south to Livermore and Oakland up north. Backed by grants from the California Energy Commission, CARB, South Coast AQMD and Bay Area AQMD, FEF pulls in cash from automakers like Toyota Motor Corporation and Honda Motor Co., plus investors such as Mitsui & Co., MUFG, JBIC and Air Liquide. But it's not just about raw station count: nailing high-flow dispensing and a rock-solid supply chain is essential to beat range anxiety and scale up adoption.

Why Heavy-Duty Trucks Need Hydrogen

Let's face it: battery electrics still sweat when it comes to hauling heavy loads over long distances with quick turnarounds and full payloads. Hydrogen fuel cells recharge in 5–10 minutes, deliver diesel-like uptime and only produce water vapor. That's a game-changer along freight corridors like the I-710, linking the ports of LA/Long Beach to Ontario and beyond—and a major win for industrial decarbonization in one of the nation's busiest trade regions.

Partners Along the Value Chain
Toyota and FEF aren't flying solo. Air Liquide and Iwatani are teaming up to build SAE J2601/5-ready stations that handle liquid hydrogen at cryogenic temps, while Mitsui & Co. brings in Norwegian tank tech for on-truck storage. Honda has been in since day one, and Nikola Corporation locked in a 10-year deal to set up HYLA-branded heavy-duty sites in Oakland and beyond. It's a classic network effect: more trucks spurs more stations, and vice versa...

Hydrogen Fuel Cell Trucks: Alberta Pilot Drives Zero-Emission Future
December 16, 2025 0 By Angela Linders

It's December 9, 2025, and Trimac
Transportation has just teamed up with the Alberta Motor Transport Association (AMTA) on a pilot destined to shake up zero-emission transportation...

...Alberta Takes the Wheel on Hydrogen
Alberta, home to roughly 4.7 million people and renowned as Canada's resource heartland, is now steering toward Hydrogen transport Alberta. Backed by fields of natural gas and a growing roster of blue and green hydrogen projects, the province's putting the Hyundai XCIENT Hydrogen Fuel Cell Truck through its paces under real, heavy-duty hauls. Through early 2026, this long-haul warrior will cycle among participating fleets, logging range, refill stops, payload impacts, and overall cost, giving us a crystal-clear view of what hydrogen fuel cell trucks can really do.

A Pioneering Collaboration
No single company could've pulled off this experiment alone. Calgary-based Trimac Transportation—a bulk-haul titan with 140 branches since 1945—teams up with Hyundai, the pioneer of commercial heavy-duty fuel cell trucks; the AMTA, which handles driver and mechanic training; and AZETEC, fine-tuning a prototype that promises more than 430 miles on one fill. Since 2022, Trimac has been experimenting with hydrogen retrofits alongside Innovative Fuel Systems and Hydra Energy, ironing out early kinks and setting the stage for today's breakthrough.

H2ICE Demonstrator Truck: Bosch's Hydrogen Heavy-Duty
H2ICE Demonstrator Truck: Bosch's Hydrogen Heavy-Duty
January 22, 2026 0 By Bret Williams
Hydrogen Fuel News
Ever wondered what the next leap in zero-emission mobility looks like? Strap in. Bosch just rolled out its H2ICE demonstrator truck, and it's rewriting the playbook on heavy-duty transport. Imagine a hydrogen-powered heavy-duty vehicle that belches zero CO₂, plugs into your operations like any other rig, and feels completely familiar. No sci-fi jargon—just rollout-ready reality.

From Problem to Possibility
Let's face it: diesel rigs keep our global supply chains humming, but they're also a major source of greenhouse-gas headaches. Sure, battery electrics work for smaller trucks, but when you're hauling tons across hundreds of kilometers, charging downtime and grid strain become deal-breakers. What we needed was a bridge between diesel's stamina and renewables' clean creds.

Enter Bosch's H2ICE (Hydrogen Internal Combustion Engine). Instead of reinventing the wheel, they tweaked proven engine tech to sip green hydrogen—delivering true zero-emission mobility with familiar performance and fueling routines.

Seeing Is Believing
This month, Chancellor Friedrich Merz swung by the Bosch Bengaluru campus to watch the H2ICE demonstrator truck roar around the test track. With its integrated powertrain humming and telematics dashboard lighting up in real time, the prototype hauled massive loads like it was no big deal. The message was clear: hydrogen can shoulder the heavy stuff, right where you need it.

The Magic Ingredient?
Green Hydrogen Fuel: Made by renewable-powered electrolysis, it burns clean and only releases water vapor.
Hydrogen-Adapted Engine: Bosch's engineers modified internal-combustion hardware so it guzzles H₂ instead of diesel—keeping the same torque, range and lightning-fast refuel.
Integrated Telematics: A 4G/5G-connected diagnostics suite that tracks everything from location to predictive maintenance—no surprises down the road.
Bottom line: fill 'er up, hit the highway, monitor performance—and forget about tailpipe CO₂.

Why It Matters
This isn't just a shiny concept—it ticks every box fleets care about:

Zero tailpipe emissions—no hidden carbon footprints.
Diesel-like refuel times of just a few minutes.
Several hundred kilometers of range—perfect for regional hauls.
Plug-and-play fit with your existing logistics network.
Picture fleets cruising into low-emission zones without a second thought, then blasting down highways without charging stops. That's a real game-changer for shippers, regulators and the planet alike...

I was speaking with a guy at Stewart and Stevenson Friday about a another problem, he was telling me two large South Korean construction equipment manufactures Hunyadi and Devlon are introducing Hydrogen for off road equipment. The owner of Stewart and Stevenson Kirby which is a large barge transportation co on the Mississippi other rivers and costal water ways are developing tugboats using Hydrogen for power, I can see Kirby just adding another barge for fuel since they transport Hydrogen already with their barges, Hydrogen is coming Cat train engines have been using it for years, I see those at the BNSF yard in Needles Ca
