Kohler Launches KDH Hydrogen Engine

November 30, 20232 days agoJo Borras

Standalone engine-builders Kohler recently unveiled a new direct injection, hydrogen-powered internal combustion engine based on its KDI 2504 TCR in a bid to reduce carbon emissions.

Like similar solutions from Toyota, Cummins, and other heavy-equipment power producers, the Kohler hydrogen engine isn’t a hydrogen fuel cell. Instead, it’s a conventional reciprocating piston engine – just one with an unconventional, low-emission fuel. Kohler says that “conventional architecture” makes the new KDH (think, “KD series – Hydrogen version”) is intended to be a drop-in replacement for the diesel KDI.
Kohler doesn’t make vehicles or gensets itself, of course – but the company’s OEM partners can expect high levels of compatibility with their existing platforms. Especially since the KDH uses the the same cooling circuit, power take-off and flywheel, engine mounting points, and intake line(s). That means no major changes will be required to fit the new H engine into existing compartments, making it easy for manufacturers to quickly offer lower emission versions of their existing diesel-powered products.

According to Kohler, the after treatment system (ATS) it’s applied to the KDH engine reduces particulate matter (PM), nitrogen oxide (NOx), and hydrocarbon (HC) emissions to “negligible levels” at the tail pipe, allowing the engine to be classified as “zero emission” per most agencies’ definitions.

The new hydrogen KDH engine and its first-ever hydrogen power system.
At the same time, the company announced that it would spin off its Energy division as an independent business with Platinum Equity as a majority investment Partner, accelerating long-term growth and decarbonization strategies for both organizations...

Hydrogen fuel news
There is a great deal of
misunderstanding circulating with
regards to the use of H2 as an
energy source
Many people think of disasters such as the
Hindenburg, mushroom clouds or even the
Challenger explosion when they talk about
hydrogen fuel. However, these are all based
on misunderstandings of the facts or
confusion between completely different
concepts.
To start, yes, the Hindenburg was a type of
airship filled with H2 and that dropped to the
ground in a massive fiery disaster in which
people were killed. However, it was not
caused by the H2. NASA and other experts
have shown that other factors caused the
fire. Indeed, it was worsened by the presence
of H2, but the Graf Zeppelin - a similarly
airship with a superior design quality - was
able to fly for almost ten years and across
over one million miles filled with hydroger
without incident.
When it comes to the other two issues, &
mushroom cloud is caused by the
detonation of a nuclear bomb, not from
hydrogen, and the Challenger shuttle
explosion was caused by a solid-oxide
rocket booster O-ring failure, again, not H2.
With historical misunderstandings
cleared up, is modern hydrogen fuel
actually safe to use?
According to the US Department of Energy.
(DoE), all fuels, by their very nature, are
associated with a certain amount of danger
Using fuels safely means preventing the
presence of a source of ignition, oxidant and
fuel at the same time. At the same time, the
DoE's official website also points specifically
to H2 as particularly safe to handle and use
when compared to some of the other types
of fuel currently in common use...
What makes H2 safer?
Among the factors identified that make H2 safer than conventional alternatives are:

It is non-toxic – Unlike conventional alternatives, H2 is not toxic to humans or the environment. The H2 itself, the emissions produced from its use (water vapor), and any unintentional spills are all free of toxins such as the carcinogens and other harmful substances in gasoline, diesel and the emissions from their use or spills.
H2 disperses rapidly – At 14 times lighter than air and a massive 57 times lighter than gasoline vapor, any H2 released or leaked (deliberately or not) will rapidly disperse, shrinking any risk of ground-level ignition.
Higher oxygen requirement for explosion – H2 can become explosive, but it needs an oxygen concentration between 18 percent and 59 percent. Conventional gasoline needs an oxygen concentration of only 1 percent to 3 percent to become explosive.
Lower radiant heat than gasoline – H2’s radiant heat is lower than that of conventional gasoline used in vehicles. This means that a flame from H2 doesn’t produce as much heat in the air around it as is the case when gasoline burns. Therefore, secondary fire risk associated with the use of H2 isn’t as high as it is with conventional alternatives.

GM and Autocar Industries have agreed to collaborate on the development of the vehicles.
General Motors and Autocar Industries have jointly announced that they will be working together on the development of H2 powered heavy vehicles equipped with GM’s Hydrotec hydrogen fuel cells.
The companies will be collaborating on the heavy vehicles powered by the Hydrotec units.
The hydrogen fuel cells will be installed in heavy vehicles such as dump trucks, garbage trucks, cement mixers, terminal tractors and road maintenance vehicles that would conventionally be powered by diesel engines. The first of those vehicles are expected to go into production in Autocar’s Birmingham, Alabama plant in 2026...

“We want to enable zero tailpipe emissions solutions for the largest, highest energy consuming
vehicles, and fuel cells are ideal for the most energy intensive applications,” said Charlie Freese, executive director of GM’s Hydrotec in a media statement.

Pilot hydrogen bus program
December 21, 2023 0 By TAMI HOOD
A trial period using H2-
powered buses has made it
possible to spot and fix
challenges with the
technology
A Canadian hydrogen bus pilot in Edmonton
and Strathcona County in the province of
Alberta has made it possible to identify and
resolve future challenges with the zero-
emission technology
The pilot was a collaboration between the
Edmonton Transit Service (ETS) and
Strathcona County Transit. The test involves
working together for 42 months with the
addition of one hydrogen bus to each of their
fleets. The fuel cell vehicles started fare
service on October 25 and the two transit
services are comparing notes, expert
consultations and solutions to the issues
they have already observed and expect to
observe through the length of the trial.
'We expected to find that this wasn't going
to go perfectly right from the get-go," said
ETS transit fleet maintenance director Derek
Hanson. ""Being in Edmonton and having that
cold snap in October was actually quite
beneficial to us because we did get some
learnings from that."...

Hydrogen news,by Julie Campbell 10 July 25
...The same analyst predicted that a much larger proportion of zero-emission trucks will be H2 powered.
In fact, while the analyst predicted that hydrogen fuel cell cars would be a “very small portion” of the car market, it also forecasted that about one fifth of zero-emission trucks would run on hydrogen. This was published in a paper titled Fuel Cell Electric Vehicles 2024-2044: Markets, Technologies, and Forecasts.

The analysis also pointed to a spectrum of other smaller markets that would be using hydrogen to power vehicles, including buses and light commercial vehicles such as delivery vans.

...Hyundai has also announced that it will be using H2 in vehicles it produces, including passenger cars, buses, trucks, special equipment, aquatic vessels, trams, power generators, and advanced air mobility.

The automaker will be using its fuel cell system brand HTWO to spearhead the transition to using H2 in the vehicles it manufactures. The brand was first launched in 2020 and through it, the automaker expects to require 3 million annual tons of hydrogen by 2035 for steel production, logistics, and power generation...

...Appel did the test driving on a clear day in a residential area on the edge of the city. It faced little traffic and didn’t travel in any areas where there was construction underway. With these ideal driving conditions, Appel was able to demonstrate the handling, including both braking and accelerating, all of which – including tight turns – were smooth to the individual in the passenger seat.

“This truck has very good maneuverability, a very good performance and, I mentioned the range, one of the longest ranges for any zero-emission truck out there right now,” said Appel. “It always depends on the application, what range you can really achieve. But I always like to give a couple of real-world references. So, for example, I drove one of the trucks from Coolidge [Ariz.], our headquarters, up to Flagstaff, Ariz., which is all the way up the hill.”

Hauling a full load
hydrogen fuel cell truck was hauling a load
of about 81,000 pounds and driving uphill, it
was still able to achieve a 450-mile range
That said, under easier circumstances, some
tests run with customers have shown that
the vehicle can run for closer to 550 miles.

Cummins has announced it will display its next generation B6.7H hydrogen engine to the construction industry for the first time at this April’s Intermat show in Paris.

The new B6.7 engine design enables a consistent mounting and space claim for clean diesel, biodiesel, natural gas, and hydrogen fuels. The main engine block remains the same with the head and the fuel system being the key changes.

They can be installed in the same equipment as today’s diesel while also using the same transmission, cooling systems, and hydraulic systems, reducing complexity for equipment manufacturers and their customers. Maintenance practices and costs are also comparable to diesel engines.

“Continued investment in the development of our internal combustion engines remains a key part of the company’s strategy towards Destination Zero.  We are targeting further improvements in performance and efficiency alongside compatibility with cleaner fuels. This must be achieved without impacting operations, weight, or uptime,” said Antonio Leitao, VP of Cummins’ off-highway engine business.

Visitors to Intermat will be able to see Cummins’ B6.7H hydrogen engine aimed at a wide range of off-highway machinery, with a top rating of 290 hp (216 kW) and an impressive peak torque of 1200 Nm targeted for Stage VI/Tier 5.

Coyote Container completes historic trip in fuel cell truck
The port cartage and drayage specialists at Coyote Container successfully completed a 400-mile delivery in a Nikola Tre semi truck powered by a hydrogen fuel cell.

William Hall, Managing Member and Founder of Coyote Container, drove the hydrogen Nikola over the hilly, 400-mile route that took the truck and its 17.7 ton trailer through California’s Altamont Pass and Grapevine Canyon on the I-5 interstate between the Port of Oakland and the Port of Los Angeles in Long Beach. One part of the trip, Tejon Pass, features an elevation that’s some 4160 feet above sea level.

“The truck is a dream to drive and I arrived at Pier C with about 140 miles of remaining range,” explains Hall. “I drove conservatively and did the steep climbs at 40 mph, much as I would in a diesel with that load profile, though I could have easily gone 55 (mph).”

Coyote Container’s Nikola Tre HFCEV semi was one of 35 hydrogen-powered trucks delivered to customers by Nikola late last year, and is reported to be the first such truck to complete a trip like this in customers’ hands.

The truck was able to “top off” in SoCal for its trip home thanks to a late 2023 deal Nikola formalized with FirstElement Fuel (FEF), which gives Nikola customers to access hydrogen fueling services at the new FEF multi-use heavy-duty truck station situated near the port in Oakland, California.

Toyota CEO Went Public With ALL NEW Water
Engine That Destroys The Entire EV Industry!
Have you ever dreamed of a future where filling up
your car with gasoline is a thing of the past? Well,
that future is closer than you think. A leading car
manufacturer has just introduced a remarkable
advancement- cars powered by water. Experts
are calling this technology a potential
game-changer that could redefine the entire
automotive landscape.

-engines would have water tanks that separate the water into hydrogen and oxygen, then feed the hydrogen to the engine as a hydrogen combustion engine-

Getting perilously close to Snake Oil territory with that one. The fundamental problem is in finding a way to break down water into it's component gases that takes less energy than is released when they recombine. This is in fact the very definition of a Perpetual Motion Machine. I do think Toyota is smart enough not to claim they have created such a thing but that won't prevent marketing folks from going over the side with enthusiasm at any hint of an excuse. When you see all science as magic it's hard to distinguish between what is and is not possible. For this to work there has to be another source of energy to tap into, so what'll it be then? Zero Point energy? Dilithium crystals? Mojo? One works just as well as another from their perspective.
