Has a school boy i did a project about farm machine,s and JCB sent more items and info than any other company and i have always remembered that with GREAT RESPECT and admiration for JCB.

Great to know we still have some amazing talent and brilliant industry still here in England .Thank you Lord Bamford

🇬🇧As an Englishman, I am so proud of all of you at JCB ! Well done everyone from a humble Yorkshire Electrician 👍

3:30 Very interesting comment there by Lord Bamford stating that owners would be able to work on repairing the engines just like shop mechanics can, I find that very positive in light of how companies like John Deer go all out to prevent owners from even touching the motor etc.

Thanks Harry, a really interesting video. Hats off to JCB for the progress they've made towards hydrogen powered heavy duty vehicles. Also, credit to the company for maintaining their factories in Britain as well as opening up abroad.

JCB is one of the few gems left in British industry.

No talking - doing! Its good to see. Thank you JCB and Harry! Please keep on going.

This should be mandatory to view by every politician in the world! Excellent thanks to you and JCB

Congratulations to JCB for grasping the nettle and developing a replacement engine, and thanks to yourself for producing this video. Excellent.

Dear Harry please investigate hydrogen production, transportation and storage at the filling stations of the hydrogen. That will be an eye opener!

Amazing, very impressive! Almost no limits for great engineering!

Brilliant presentation, very informative. Thank you Harry

I worked in the same design office as Ryan at Triumph Motorcycles 20+ years ago. I'm very impressed and humbled by how far he's come.

Well done JCB, and not just some CEO, but the boss himself, that to me says a great deal, he's delighted to show what his team have done, congratulations JCB. Harry as a farmer's son, and an estate manager, I wondered how we would get the grass cut, battery power is just to heavy, I like this system. Thank you for taking the time to show us our future

Richard Hammond has definitely changed the last time we saw him..Thanks Richard very much enjoyed your latest JCB Engine video

Excellent video, I’ve wanted to know about hydrogen fueling for years now, I’m also a farmer and could just not see how I could operate on battery powered tractors, excavators, pumps ect. I’m impressed and now have a more positive outlook for the future of agriculture and pastural businesses, especially here in Queensland , Australia where we have huge tracts of land that need to worked efficiently to produce food for the world market. Go JCB.

Thank you so much for showing us this. Great to see some companies going down this route, electricity & battery technology isn't the answer to everything. I hope JCB prosper developing this tech.

Great video Harry! I had the chance to spend a week at the JCB test site quarry last summer for work experience and got to try out the hydrogen machines. It's really amazing how much technology has progressed with these engines. I think 2023 is going to be a really exciting year for more developments!

Great video Harry - so good to see this great solution for these types of big heavy hardworking machines. Thank goodness JCB have poured money into this & developed it given the lack of interest & support from UK Gov.

Harry thank you this was fascinating and enlightening. Coming from the haulage background I have long had an inkling that flogging away at batteries for our needs just won't do it for a vast spread of road haulage operations. So I am surprised the major truck manufacturers have not started this push towards Internal Combustion Hydrogen. I think Hydrogen makes people think of fuel cells and thus it becomes very misunderstood. JCB make what they have gone for look easy! Interesting times ahead, keep up the great work on documenting this stuff

People used to joke 'hydrogen is the fuel of tomorrow... and it always will be.' It looks like tomorrow is finally arriving - well done Lord Bamford and JCB! Politicians can decide what they like but it will always be real world innovators who shape the future. Great video Harry, exciting times.

Once it gets to one dollar a kilo,the govt will tax it up to five.

JCB... a jewel in the crown of innovative British industry.

For Africa this is a game changer. JCB through their Raze H2 business (Jo Bamford's business) have a deal with an Aussie firm, Fortescue to establish a supply of friendly Hydrogen (as green as possible). With renewable energy costs falling daily means the costs of H2 production is falling rapidly.

The future lies in a mix of technologies. No one technology or solution fits all applications.... automotive, agriculture, mass transit, aviation etc. This solution would appear to suit the agriculture application well (unlike battery electric) but the main issue is that you don't just dig a hole in the ground and suck up hydrogen, it's massively energy intensive to produce. So the environmental credentials of each technology/solution is still a challenging problem, just like other technologies. Very interesting though.

Great innovation from JCB and definitely the right early adoption move for the company to thrive in the market.

Thanks Harry - these are some of the best videos you do. Mega hats off to JCB (British and family owned, remember!).

Fascinating insight into the world of hydrogen powered machines. Really enjoyed watching. Great to see Stanley is back!

Brilliant! JCB, British innovation at it's best. So exciting. Well done Lord Bamford & JCB expertise

Brilliant. Great British engineering with a confident commitment. Light at the end of the tunnel.

Harry, please make more videos about this, especially in terms of hydrogen production, transportation, storage, network of places to refill, etc. it feels like these aspects of hydrogen could use more light shined on them.

Great summary. With any energy ‘solution’ you have to consider the whole back story.

Great to see, I remember watching your previous visit to JCB and it is great to see how far they have progressed their development, at least one British manufacturer who gets on with it ! Obviously the fly in the ointment is the production of green hydrogen but I'm totally in agreement with you, the end result will be a 'mixed' solution rather than one size fits all. I have always thought that the emphasis on electric cars which costs ridiculous amounts of money is totally misplaced, we need to tackle the big pollouters who run 12+ hours a day like buses, artics and trains to name a few.

Great video Harry, Great to see a British company at the forefront of hydrogen power.

11:50 Whilst there is no carbon in the fuel, all internal combustion engines consume a little engine oil during operation. It’s just the way the engine functions. I hope the redesign for hydrogen has incorporated some secret design elements that reduce the oil consumption to virtually zero. JCB is truly a legacy company that the British can be proud of. I wish them all the success 👍

I have a 3.5 litre car. Wouldn't it be nice if I could retro-fit an hydrogen power plant? Brilliant work JCB and great video Harry.

Great video Harry, you asked all the technical questions many journalists in the construction industry haven’t asked in their visits. And thank you for putting the nox question to them. As an owner of construction plant I am following developments of JCB and hydrogen very closely. Battery tech as it stands just won’t cut it for us

Great video Harry. One of the best. Thank god we have people like Lord Bamford and his chaps. I have no doubt they are treading the right path. Great stuff. Keep us updated👍

Good job a British company has got its head screwed on and moving forward. Still using the internal combustion engine but now with hydrogen well done. Lord Bamford and the team of engineers great staff.

Fantastic video. I love how enthusiastic and excited the JCB engineers are about the project. At a cost of £15 per litre- at today’s prices hydrogen will cost £150 per day. At £20 per hour + overheads an excavator driver might cost £240. The hydrogen is not insignificant, but it is not going to dominate the cost of doing a job with an off-road vehicle. I can see this being adopted for work in ULEZ zones, and spreading out from there.

Thanks for doing these videos Harry. I'm really interested in what the future holds and I found the first video to be very informative. This one is a great follow-up.

Very smart process JCB for designing from the ground up an entirely new engine that performs exactly the same as the older Diesel one! I congratulate you on your efforts to make our future greener and thank you from the bottom of my heart! Also to have thought of creating the vehicule that transports the Hydrogen to the machineries in the field in just brilliant! As an Engineer, I am so glad to see beautiful projects such as these come to light! Bravo!!!

JCB is doing GREAT work.❤

excellent explanation of the tech, and JCB are brilliant (despite Lord B!)

What a fascinating video and congratulations to JCB. The Government needs to pull its finger out and get realistic about its Net Zero goals.

When I was a kid in the '70's, people talked about hydrogen power, but many of those talking said it wasn't feasible. Nevertheless, it was thought that hydrogen - were it ever to materialize - could possibly be an answer to our biggest energy problems. Now that it's here, however, it sounds like there are still some obstacles to overcome. It will be interesting to see how this develops in the future. Thanks for an educational video.

Imagine this, it's 11:00 pm on December 24th. You're 300 miles from home sitting in a Mall parking lot with nothing open for over a mile away. Only one spot at the charging station is working and it is SLOW, no fast charging available. It's going to get down to -20f tonight and your Heater is using 70% of the chargers output. You know the range of your vehicle is cut almost in half because of the temps and it will be morning before you get to 80% charge. You will need to charge two more times before you get home...hopefully before dark. Now, aren't you glad you're saving the planet and driving an electric vehicle! Thank You, Lord Bamford for giving us more options and Thank You, Harry for covering this technology.

What an excellent and very informative video, Harry. It's great for JCB to allow you to share this excellent technology. it looks like a better system to battery power.

As someone who works for a company that converts trucks, we are currently struggling to go battery electric, for our specific application. Battery technology just isn't good enough, at present. We do convert CNG powered trucks, but they also have issues with range/hours in use. I just wonder if Hydrogen is much better. Hydrogen at high pressure is a bit worrying, if things go wrong , a road crash for example. Another problem is making hydrogen, its energy intensive. We'll see if anyone else in the construction/agri world( John Deere, Caterpillar etc) goes down this route.

Congratulations to Lord Bamford, for the foresight into using hydrogen. And the engineers at JCB in making it work. Great program Harry

It would be a safe bet that within 1, possibly 2 generations, a fair amount of the world could go into hydrogen power. Unfortunately, I won't be around to witness that. Except for videos like this. Thank you for sharing.

I have a JCB backhoe 214 excellent Allis Chalmers had a hydrogen fuel cell farm tractor experiment in 1954. Excellent 👍 Cheers

Lord Bamford. A forward thinking man. Respect

Thanks Harry good video, good to get some answers on the high Nox question and nice solution they have gone for lower firing temperature. One thing to keep in mind though, especially for mainstream products (cars) using high volumes of hydrogen would become problematic as the complete cycle efficiency from green energy to hydrogen makes it non competitive vs battery. Green energy converted into kinetic energy through a motor (~95% efficiency) and battery losses take to you say 80% efficiency. However, converting green energy to hydrogen through electrolysis 75%, then combustion at 40% gets you to 30% cycle efficiency before you have taken into account compression losses to pump it to high pressures. Happy to educate you more if you are interested!

Really Really Great video that was a wealth of information but ill tell you one thing ill miss that Beautiful Diesel Rattle lol thank you mr Harry !!!

Sir Anthony Bamford. A true captain of industry.

Great progress from JCB, hopefully other manufacturers will take it up to, especially the truck industry. Fantastic video keep this kind of content coming

Great video, Harry, and a good follow up to your July 2021 video. It is so disappointing that the British Government seems to be totally focused on electric as the only solution to meeting zero emissions in spite of all its well recognised shortcomings. Maybe we should all be writing to our MPs to wake them up to alternatives such as this one you have highlighted here. Keep this stuff coming!

Great stuff…I’ve been calling for hydrogen for years now, glad to see some of the big lads getting it right.

Fantastic-This country does still matter and this work by JCB proves that-simply fantastic...

Great to see more of your content on alternative fuels, Harry. I'm still not sold on the infrastructure and production sides of H for fuel (tho it's promising), but, moving forward, we obviously need to move to a carbon neutral setup yet the industrial and commercial sides of that is immense and doesn't get much press coverage .... Good on you for continuing to do so.

Really interesting video Harry! Hydrogen seems an easier shift, than the use of batteries for our bigger kit 😊

Thanks Harry; congratulations to JCB, but without your presentation people like me would not know about it.

Hat off to JCB paving the way forward, much respect 🙏👌

Fantastic video Harry. This is fascinating and hats off to JCB for their work on this. Realistically, this seems like the future rather than batteries and EVs.

I love this, but no one talks about the loss of hydrogen while the equipment is unused, due to the pressure tank needing to relieve pressure as the tank warms up.

Lord Bamford is a inspiration a innovator. The UK 🇬🇧 should be very proud of this representative of forward thinking. JCB is a world 🌎 market leader 👏 🇬🇧🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧😊👌

Whoever designed the hydrogen bowser must have been brought up in the seventies watching Space 1999. :-)

This is an excellent video, as a diesel engineer im watching the hydrogen world with a keen eye. I do wonder what the crash protection of the storage tanks is like, 350bar is a huge amount of pressure to let go. The huge RPM of the turbocharger makes me wonder if that's a single point of failure.

It takes 50 kWh of electricity to produce 1kg of hydrogen from pure water.

Well done Harry excellent report on JCB s hydrogen engines really interesting & imformivitive 👌

Absolutely superb work from JCB Harry. And thank you for that insightful video.

That almost sounds like a diesel engine to me. Going to be interesting to see this develop.

I worry about the storage of Hydrogen as it is kept around 350 > 700 Bar. I foresee nasty tank explosions in the early days of this gas being deployed on sites and farms. You're a brave man standing that close to the tanks. I agree charging battery-based building site or farm machines in remote areas is not going to work in many cases. But we must not forget that once you produce this gas, compress it, transport it, and burn it in an engine, you only get around 28% of the energy you put in at the start. So everything we can electrify we should for sure before reaching for Hydrogen. I agree for some long lorry/truck trips that have to be over 400 miles or long-distance shipping, then Hydrogen is one of the only options. But there are plenty of lorry routes under 400 miles where an electric truck will work fine. The Regen braking on a battery lorry will re-capture up to 20% of the energy on a typical run and do over 90% of the stopping work, whereas a Hydrogen lorry would need to apply the old style brakes, which need replacing just like diesel trucks, thus still generating brake dust. I am sad, Harry, that you dismissed the work of Tesla, and the Tesla Semi, a large full truck capable of up to 425 miles at full load (37 tons). This could replace many routes in the UK and is 90% more efficient than any Hydrogen truck can ever be. Also, engines that burn fuel or gas still need oil changes and new parts as you found out, producing parts has a carbon impact at every service interval. Electric motors do not, and the battery can be recycled at the end of its life. As you say, it needs to be a multi-pronged approach. Thanks for the video and for getting us debating.

JCB, Toyota, Cummins keep on moving further 👍

I have visited JCB what an amazing company and Lord Bamford is an amazing man.

Very exciting. Im delighted to see such a big company is pushing for this technology. it wont be today or tomorrow that we will see it perfect but you have got to start somewhere. Just like the first ICE engines they weren't perfect and took awhile to get to where they re today. please bring more videos like this. Loved watching this.

On a tour of the Cummings factory 20 years ago they said that they believed if an engineer could come up with a commercially viable method for storing gas in a similar volume as diesel in a compact size they would be billionaires. It is certainly an interesting direction along with the CNH methane engines it will be interesting to see the true viability in the sector as a lot is certainly going to depend on infrastructure especially given how a lot of locals view planning applications for such things .

Brilliant video Harry. So interesting. I've said for a long time hydrogen is the future. Good for Farmers and environmental.

This is a super interesting video and congratulations to JCB for their hard work. I am in Australia and would like to see you develop in Australia as well. Well done Harry

Great video, and great efforts by JCB. Could be interesting to learn more about the efficiency comparisons with Fuel Cells. Historically FuelCells have been more efficient. As a side note it is interesting to see that the drive to hydrogen in Construction Industry is driven by Historic Racing entusiast Lord Bamford. Our company Applied Hydrogen doing similar work but with Fuel Cells are also run by Historic Motorsport enthusiasts. We bring the world forward with our passion.

I really enjoyed this. This sounds really promising and I hope this can find its way into all sorts of vehicles. EV, hydrogen and alternative fuels is a well rounded approach to sorting the issue.

Brilliant Britain 🇬🇧... This is how you do it...let's have more positive...👍

I can't help feeling this could all go very wrong and bankrupt JCB. It's a high risk strategy and I hope it works out.

A superb post there Harry. It strikes me again having watched the previous video two years ago that Lord Bamford is an amazing chap. I really hope all JCB’s R&D efforts can win the day commercially. I do have my concerns about Hydrogen production but hopefully they know something that we don’t. Fingers crossed that if there’s a Part 3 to this story that the final outcome is a good one

Thank you for a well presented and informative video! 🎉😊

Loved the video. Thank you Harry JCB and the pooch.

How are they avoiding the steel suffering hydrogen embrittlement?

You have to remember that Green Hydrogen is not a source of energy, unlike the grey Hydrogen that is currently used by JCB. Green Hydrogen is just a means of storing energy just like a battery. You start with electrical energy, throw away 25% of it to convert water to Hydrogren, then throw away 10% to compress it, throw more away transporting it on a tanker to a filling station. Throw more of it away to compress it in to the to the vehicles tanks. Finally if using an internal combustion engine throw 50% of it away as waste heat. Probably the energy losses could be justified for some applications (like aviation) but the infrastructure to distribute it is more of a problem. We can't put more than 10% hydrogen in to our current gas network because it will embrittle the plastic pipes. I can't see the country being able to afford to double up our gas network with a hydrogen network even if we just connect filling stations. This is because Hydrogen is really difficult to pipe because it leaks out through conventional gas joints and you can't use conventional plastic pipes which would make a hydrogen pipe network more than double the cost of an CNG network. As a result it is always going to have to be transported by tanker. However Hydrogen compressed to very high 700bar takes up 6 times the amount of volume for the same energy as petrol and liquifying it which takes a lot of energy only reduces this to 4 times the volume. Consequently you are going to need 6x the number of fuel tankers to transport it. Although I would love Hydrogen to be a competitor to battery technology I just can't see it happening on a wide scale.

,, The Smith family members will love driving these around the Huge Bamford Family Estate ,,

Absolutely brilliant video Harry, thanks for that.

Really love the video Harry, and the eagerness to learn about modern tech, and show it to us!. Going to get a lot of hate for this one, but I really want to be convinced hydrogen is better than BEV, especially for these applications, but unfortunately the physics of hydrogen really isn't working in my brain. I'm not blinded by the electric/diesel/hydrogen side of the fence, but you really can't beat the numbers, and ultimately consumers will buy what's cheapest to run, and what is the best experience. Off the napkin maths from their H2 numbers seems to suggest that the first tractor shown only uses about 250kWh a day worth of Hydrogen? In that size of machinery, 250kWh worth of battery capacity is child's play... and that's on current chemistry not future. Of course that may not be possible to charge overnight in all locations, and whilst most locations could, the same 'diesel bowser' approach applies, where a MWh scale battery can be located to site in exactly the same way, at a MUCH lower unit cost. We already use high-power feeds for sites in most examples anyway, so the work is almost already done for us. For every 1 tanker of diesel delivered now, you'd need 6 of them for hydrogen because of its energy density - that sounds like a lot of disruption to me for no cost benefit. The reason BEVs have won over H2 in cars are because they provide a superior user experience, not because they're green. Whether that's the experience of the drivetrain or the cost of operation. To me, JCB bragging that this will be indistinguishable from a diesel experience is their biggest problem, there's absolutely no incentive for the user to move other than the flamboyant choice of paint colour. The fundamental vehicle architecture needs to change to take full advantage of each fuel type (like where ground-up BEVs are much, much better than ICE conversions, so same goes here - they should look completely different to conventional designs), and since the user experience with H2 isn't better, and for it to be sustainable all H2 must come from renewable energy anyway, physics is screaming for us to cut out the useless middleman. The promise of green H2 really does feel like the gateway to blue/grey H2 which is just burning gas - bringing us back to square 1 (I fear this is the idea all along anyway). I understand that JCB want to reuse as much of their sunk capital in diesel development as possible, which makes sense for their business, but in terms of the technology it's just all wrong. I think the bottom line is that for every 1 wind turbine or solar panel needed to power BEV machinery, there needs to be 2 or 3 for H2, that means at least double the land use, double the capital investment, and double the unit cost for the same output. That seems to be the fundamental floor that H2 can never overcome. Whilst we need to explore every new technology to reduce our impact, like this one, it needs to be better and cheaper for the user, and if it's not it's time to move to the next. The numbers don't lie, and the market will weed out the worst technologies either way...

Hello Again, Well Harry this really just shows what a company (JCB) can do when the owner wants to make changes, brilliant, very impressive and well explained. Regards, RichardA.

Truly educational. Comprehensive breakdown of the how's . TY

Frigging amazing. Awesome. The future is exciting for ICE vehicles.

Very interesting! Kudos to JCB for making the investment and sharing it with you. Perhaps a fuel for the bigger family cars as well in the future?

Very interesting video Harry! Fantastic to see how fast their progress has been going. But I think batteries biggest advantage over hydrogen is still the price. it's just so much cheaper and most of the problems with long charging can be done with battery swap or fast charging. Anyway its great either way which will be used :)

This is a Real Big Feather in the Cap of ""British Engineering"" !!!!!!!!!!!!!!! Gives a Feeling of Pride !!!!!! Good On Ya JCB and Sir Bamford and All the Team. Though i believe CAT has a Hydro engine for many years

This is the best vid you have done so far Harry. Well done to you and even more so to JCB.

Working on the edge of the development of bio-hydrogen technologies, it's great to see the other end of the hydrogen fuel system so well developed - this will push others in the sector significantly I hope. Really good video, thank you.
