HANOVER, Germany — While the auto industry struggles to convince consumers that hydrogen fuel cell vehicles have a place in daily transportation, truckmakers see huge potential for the technology.
It’s a matter of chemistry, Andreas Gorbach, Daimler Trucks’ technical chief, said at IAA Transportation 2022. No battery chemistry will ever outperform how much energy engineers can store with hydrogen, he said.
“If you take the elements with the biggest difference in electrochemical that gives you the highest energy, the highest voltage and the highest potential energy density cell, you would never come even close to the hydrogen,” Gorbach said.
Even with a significant breakthrough, battery chemistry might only reach a 30th of the energy that hydrogen packs.
“There are not elements that can compete with hydrogen,” Gorbach said.
To be sure, there are still major obstacles to overcome before hydrogen fuel cell trucks can start to replace diesel tractors. There’s almost no fueling infrastructure. The existing hydrogen supply chain couldn’t support trucks by the hundred-thousands.
And hydrogen refining is dirty, defeating the purpose of a zero-tailpipe emissions vehicle. The industry must ramp up producing hydrogen with solar, wind and other renewable energy to fulfill its green promise.
Gorbach worries that the infrastructure bottleneck will leave trucking companies without the best option as governments ban diesel engines.
Even as it develops fuel cell trucks, Daimler continues to push into the battery electric truck market. It unveiled a European model with new battery chemistry at IAA Transportation last week. Daimler CEO Martin Daum told Automotive News that the powertrain and battery chemistry on that truck would make its way into Freightliners plying U.S. roads in several years.
The buzz at IAA centered on battery electric and hydrogen fuel cell models. Daimler, Volvo, BYD, Iveco and nearly every other Class 8 truckmaker placed electric tractors front and center at their IAA booths. They parked the diesel models in secondary positions or outside at the sprawling Frankfurt complex.
Daimler, a standalone truck builder after its December 2021 spinoff from the corporate parent of the Mercedes-Benz car business, touted its hydrogen fuel cell at multiple IAA locations.
Visitors to its primary booth embarked on quiet and smooth rides in Daimler’s GenH2 fuel cell concept big rig. Elsewhere, the German company displayed the latest generation fuel cell stack in development at Cellcentric, a 50-50 joint venture with Volvo Group.
In briefings and interviews, Daum discussed hydrogen technology with a sense of urgency, influenced by the corporation’s timetable for phasing out diesel transport.
“We are in a carbon economy, and carbon heats up the world. … That’s not a world we want to live in,” he said.
Fuel cell powertrains, which use hydrogen to generate electricity to run motors, are a logical substitute for diesel engines to haul goods and materials over the long routes of the U.S., he said.
The weight of the fuel and powertrain is less than that of the heavy batteries electric trucks need to cover similar distances.
Less weight allows motor carriers to haul more freight. And fuel cell trucks refill at about the same speed as combustion engine counterparts.
Volvo also expects fuel cell technology to work better for long ranges and extreme loads.
“We know that it will depend a lot on the infrastructure and the availability of green hydrogen and green electricity,” said Jessica Sandström, Volvo Trucks’ global product management chief.
Volvo is testing fuel cell electric trucks that can run about 600 miles between fueling.
It plans to have customers in Europe testing the trucks in 2025. That will extend to the U.S. and other markets in the following years.
Nikola Corp. is already testing a fuel cell semitrailer in the U.S. and unveiled a version for the European market at IAA Transportation. It plans to launch commercial production of the truck at its factory in Coolidge, Ariz., in the second half of next year and then in Europe the following year, Nikola President Michael Lohscheller told Automotive News.
It also is building fueling infrastructure, starting with one station at the Port of Long Beach and two others in Colton and Ontario near major Southern California distribution hubs.
“I could sell you a truck, but good luck finding hydrogen. … I have to make sure that I can offer you the hydrogen as well. We need to bring these things together,” Lohscheller said.
Others are also testing fuel cell trucks in real-world conditions. Toyota Motor Corp. worked with Kenworth to retrofit 10 diesel-powered Class 8 trucks into fuel cell vehicles for a pilot program in Southern California.
Its success convinced Toyota there is a market selling the zero-emission technology to truck manufacturers. It will build a dual fuel cell module assembly line for heavy-duty commercial at Toyota Motor Manufacturing Kentucky next year.
It plans to keep a couple prototype fuel cell trucks for its parts supply range in the Los Angeles region.
Other companies are exploring urban package delivery and trades.
A partnership between Hyundai Motor Co. and Iveco Group unveiled the eDAILY Fuel Cell Electric Vehicle at IAA. It mates Iveco’s large van to a fuel cell system that first appeared in Hyundai’s Nexo crossover.
The van shows how automakers are repurposing zero-emission tech developed for cars in larger commercial vehicles. The Toyota/Kenworth Class 8 trucks pair fuel cell stacks designed for Toyota’s Mirai sedan.
These advances demonstrate how transportation is leaving a world where internal combustion engines provide an answer for nearly every mobility use, Gorbach said.
Sandström agreed: “We need to be prepared for everything. There will not be a single silver bullet solution for everyone.”

Almost your complete physique, nonetheless, is active in a technique or
one other to stabilize you when pressing. Muscle fibers from this complete vary come collectively into one
single tendon that inserts on the entrance of your upper arm (humerus).
Let’s take a better take a glance at every of these muscle
teams and the method to train them.
Take seconds of relaxation between the sets of the
first grouping of exercises and seconds of rest between the units
of the second grouping of workout routines. There
are numerous completely different combos you presumably can create a
full-body exercise with and can make the most of totally different rules
inside the workout to add selection and hold progressing. One huge
pro of this program is once more that it might
be appropriate for a newbie, offered they use a lower complete set quantity for every exercise
and watch the volume. In addition to these lifts, you can also throw in a couple of isolated workouts if you want to hit the smaller muscles individually.
This is one other extraordinarily intense coaching program so you
should always monitor restoration between sessions. Doubtlessly the one con you could
see with this approach is, should you struggle with restoration,
you may not be succesful of work out as regularly as you’re accustomed after performing
this protocol.
Whereas many types of train offer well being benefits, the one reliable
approach to drive muscle development is to make use of
your muscle tissue against moderate to heavy resistance.
In addition, muscle progress is restricted to the muscles getting used.
This process of accelerating your muscle mass is called muscle hypertrophy, and it’s a main goal of resistance
training. Attempt to lift 5-10% heavier weight each week for three weeks, then deload within the fourth week and repeat this sample until you presumably can not enhance weight.
This progressively rising load will allow you to develop your power
and measurement in the long run.
Years from now, you’ll look again and thank “Past You” for starting energy training right now.
So if you’d prefer to construct muscle, however not
as much as a professional bodybuilder – don’t worry, it’s not something
that happens by accident. In addition, some ladies with larger amounts of
muscle mass choose to take steroids to help help them in gaining muscle,
because we merely don’t have the hormones naturally to get to that dimension. You simply need to verify you’re getting enough
energy and sufficient protein in your system to advertise muscle progress.
As Quickly As you reach a sure physique fat proportion you’re pleased with,
then you can improve your caloric intake to build more dimension.
Yes, a 5 day workout cut up is among the finest options out there and
is highly well-liked. It does require a major time dedication,
with training sessions scheduled for 5 days a week.
Compared to different workout splits like three or four days, it calls
for a better degree of dedication. Following a well-designed plan is essential for maximizing your energy training.
By doing so, you’ll find a way to preserve consistency and make clear progress.
Building muscle and power requires strategic planning, and your training break up
is a crucial aspect of this strategy.
The reason for that is that pure strength gains typically require you to carry in a decrease rep range,
whereas this program pushes it a bit additional.
For anyone looking to pack on some serious muscle mass, one of the high priorities shall be to determine
what one of the best bodybuilding workout to
comply with is. There are a extensive range of different exercises
out there, so selecting the one that can suit your wants finest is essential.
Workout Routines the place you prepare a number of muscular tissues on the identical time are called compound workouts.
They are time-effective and make an excellent basis in your training
routine.
You Will reap the reward and satisfaction of figuring out you gave it your all, in addition to how you
feel and look. If you’ll be able to only get three units of 5 reps at 62.5 kg, you
can stick with that weight for the following few coaching periods and try to get all sets as much as six reps earlier than you enhance the load again. If you probably did three units of six reps at
60 kg (~130 lb) within the bench press final workout,
you could attempt to do three units of six reps
at 62.5 kg (~135 lb) in the next workout. They might try to increase the number of
reps for a couple of workouts before they increase the load, and then concentrate on increasing the reps for
few exercises once more. This means that
doing this push workout routine as soon as per week
is not dangerous; you’ll most likely achieve properly from that.
But you could in all probability develop somewhat sooner should you repeated this
exercise slightly sooner. Make it a aim to try for
more reps on each set of every exercise.
Like many of the different shoulder exercises, the important thing to proper kind
on this train is to begin with a really light weight
and concentrate on the muscular tissues working.
Whether you’re a beginner or superior lifter, these workouts will help you pack on muscle
and improve your shoulder strength quickly. Aim to complete the following workouts alternating between them over the course of
two to a few days per week with at least in the future off in between for rest.
The few isolation workout routines are added toward
the top of the exercise to help additional convey out muscle definition and
increase the muscle pump you experience. Take between 60
and 120 seconds of relaxation on the workouts apart from the
train where you would possibly be to carry out seven units.
Here the rest period needs to be shorter and saved round 30 seconds for max muscle pump.
You want to eat 300–500 energy per day above your
baseline wants for sustainable muscle gain with out extra fat acquire.
The primary goal of eating to achieve muscle throughout a bulking
phase is supplying your physique with enough vitamins to grow but not so many
calories that you just placed on more fats than muscle. Additionally, current analysis means that different people may respond higher to lower or greater repetition ranges in terms of constructing
muscle.
Let’s begin with the 5 day break up that most individuals consider in phrases
of a 5 day workout plan – the Standard 5-Day Cut Up.
Whereas at some point you prepare decrease pulling and one other
you train lower pushing, you’ll be able to’t isolate your quadriceps,
hamstrings, and glutes when performing compound movements.
You can target all muscular tissues in per week with comparatively shorter, targeted periods, making it simpler to
take care of consistency and keep away from fatigue. Plus, the routine
allows for prime frequency without overtraining any muscle group.
For instance, after a “push” workout, your chest and triceps have time to recuperate while you focus on your again and biceps on the “pull” day,
and your legs get a break on the “legs” day. Balancing your training
helps prevent muscular imbalances, which in the end reduces the
chance of harm and optimizes overall power and muscle growth.
The superior push pull legs routine takes you on a six-week muscle-building journey, whereas the intermediate one is seven weeks lengthy.
Sooner or later, you’ll have completed the PPL program of your selection.
For most people, resting for 2–3 minutes between sets
is ideal.
A PPL routine may be adapted to swimsuit numerous coaching types
and frequencies. You can use the same basic framework for
coaching three, four, 5, and even 6 days per week.
Agonist-antagonist coaching is mainly training opposing muscle tissue in the same workout.
However a exercise log removes much of the
guesswork and simplifies the complete process. Your workout log is principally your private fitness diary.
By tracking your workouts, you can play detective and spot patterns.
With Out tracing your exercises, you might miss these clues
to your progress. As A End Result Of every person is completely different, there’s no
precise ‘marker’ on how a lot quantity is enough.
You have to attempt to tread the stability between doing
enough for muscle mass, but not too much in order that you’re
feeling tired, beat up and weak. After a while you noticed that
your progress started to slow down. [newline]The leap in weights you had been utilizing for squats, presses and pulls wasn’t as fast and now if you
look within the mirror you wrestle to see any variations in your physique from last month.
Run for 10 seconds, then stand on the rails for 30
seconds, then run again. You’ll essentially keep doing this
till you’re gassed out. He holds a journalism degree from the University of
North Texas, the place he competed in powerlifting. His final competition was
the Texas State Open in December of 1982, however has continued to review and
practice muscle power and hypertrophy. He is a four-decade veteran of the
medical device trade. Finally, arguments for the “big lifts” track again to
ego and the underlying want to look badass within the fitness center.
For certain, a sissy squat will not draw a crowd and will elicit no “beast mode” compliments…other than from the few who’ve tried them for themselves.
Sticking with the dumbbell bench press example,
you’d warm up after which perform eight to 12 reps pushing the set to failure.
Following your top set, you’ll cut back the burden by about 10 to 15 p.c and do two more units of eight to 12 reps.
Samuel says true beginners (people with less than six months of consistent health club experience)
should carry out eight to 12 reps for all workout routines.
This will let you build muscle and master the movement
in a typically safer rep range. You have to eat extra
protein than your physique is using in order to continue to construct muscle.
Protein is present in a wide selection of sources that embody animal-,
dairy- and plant-based meals. Basic dietary tips recommend consuming between zero.8 and 1 gram of protein for each kilogram of physique weight every day.
The push press is a good addition to any push-day exercise whenever
you need to incorporate a bit more power and athleticism.
If you must solely do one shoulder train, the overhead press is a great choice, which is why it is included in a lot of
our shoulder workouts. That’s why we’ve compiled a list of the ten finest shoulder workouts for muscle and strength.
Not solely do well-developed shoulders improve your physique, however in addition they play a vital
function in higher body power and total athletic efficiency.
Whereas the squat is a good lower physique train, it doesn’t hit the hamstrings very exhausting, which is
the place the leg curl comes in. Although the seated leg curl has been proven to work higher than the lying leg
curl for building hamstring size, both are nonetheless very efficient, so just use whatever
machine is out there. Creatine is a substance that’s naturally found
in muscle cells.
Sure, however it’s really helpful to begin out with conservative weights and focus
on learning correct type to keep away from injury and
really get probably the most out of each of your workouts.
Whether you’re a seasoned lifter trying to break by way of those
dreaded plateaus or an intermediate lifter looking for fast positive aspects, this program is your guide
to attaining large results in much less time. You take the time to evaluate key markers of body composition and performance.
We’ve already calculated that a 200-pound male with
10% physique fats has a BMR of two,332 cals. If he has a very
lively way of life, he’d multiply this determine by 1.725 to reach a TDEE of four,
022 cal. This is his energy balance—eat extra and he positive aspects weight; eat
much less and he loses weight. To begin, you need to have body fats of 14%
or much less, have no much less than 18 months’ coaching expertise, and be willing to commit to five hours’ training a week.
If we could all add 10lbs to every exercise each workout, we’d
all be lifting 1000’s of kilos by now. This is nice and means progressive overload has
occurred. However, in this example you did not get all three units within the 6-8 rep vary.
In this 3 day version, each muscle group will get skilled as soon as each 4th or fifth day.
While it’s simply slightly less frequent than the 4
day model, it’s nonetheless perfectly inside the ideal frequency range for constructing muscle mass on the optimum fee.
The truth is that real bodybuilding workouts haven’t changed that much over the a long time.
It automates your programming, adapts to your progress,
and optimizes your workouts, so that you don’t have to overthink
it. However, while full physique splits can preserve your
muscle mass, they may not be optimum for long-term growth.
The lack of specialization can result in insufficient volume for particular muscle
teams. If your objective is to build muscle, think about this method a stopgap quite than a permanent
solution. For occasion, many bodybuilders advocate for splits that enable for muscle
recovery whereas maximizing pressure. They usually argue that coaching a muscle group two
to a few instances every week can enhance progress.
Put merely, calories are simply models of vitality, and your body’s ability to burn energy is identified as your basal metabolic fee.
By boosting your body’s metabolism, you’re truly growing your inner temperature,
(also generally recognized as the thermal effect). This thermal effect, burns more items of vitality
(calories), thus resulting in lipolysis or the breakdown of fats cells.
I do suggest that you simply do some type of cardio 3-4 times every week.
Of course, how a lot, what sort, and the way lengthy each duration is
dependent upon where you’re currently, and what your goals are.
Trainer Cory Gregory, a 45-year-old father of three, designed this
plan to transform your physique. Protein powders are sometimes used to supplement large quantities of protein between meals.
Conversely, if weight isn’t rising, you might have to eat extra.
You can monitor calories, weight, and measurements all in one place.
We’re going to start out this efficient exercise with a warmup
