What does this even mean?

We don't need hydrogen. You might need it, to keep a decrepit industry afloat. Why would you use a fuel that vastly expensive to make, incredibly ineficient and difficult to store?

Oh just shut up. Just make electricity. There is no way to even come close to the efficiency of batteries. Why funnel money into this futureless shit?!

55:00:00 Again, I don't know how you can just be off by a factor of 1000. Maybe because you wouldn't be believed if you did the math correctly.

Some of the numbers for data centers look seriously specious. If each of the 1 PB modules uses 17 kW, and there are 135 million of these, that's about 2.3 TERAWATTS. To which I reply: TAKE A DEEP BREATH. First, I very much suspect that 17 kW is a power rating, not an average consumption. He's talking about using all, or nearly all, global electricity in just FOUR YEARS! Well, I don't think so. Also, there surely must be power management techniques to hibernate, or sleep, modules containing rarely used data. It could be brought up in seconds. A couple more things: You don't have to have a backup for everything online at all times. If you're really concerned about that, you can distribute storage over many sites, dispersed over a wide area. Again, all but a small percentage of that storage is going to be rarely accessed. You also need to remember that the equipment gets more efficient over time, fast enough that differences are noticeable even with the four years or so that he's got in mind. The land requirements are also less than he suggests. Why would you put everything in one layer? That's insane! But even with that, you're still talking about 100 square miles or so. (You really should use metric. Come on, this was 2021.) OTOH there is waste heat, which could theoretically more than double your power requirements in some comical worst case. So use heat pumps, maybe ground source, and/or locate in a really cold climate. I don't think anything is going to hinge on that. I'm also skeptical about how much hydrogen is going to help with any of this, but that's a whole new topic.

Thanks for sharing the hydrogen economy is essential part of energy transition.

Pink Hydrogen is just totally overlooked. I think you all have made an error. Nuclear energy is going to take over and make electrolysis amazingly cheap. Europe allowed nuclear in their taxonomy and soon we will have our Energy Bill past with nuclear in it too

Buy Energy Fuels UUUU. They will provide the nuclear fuel for the upcoming SMRs that will be placed at old power plant sites (coal, LNG etc). Then all these companies are worth investing in.

Amazing.

If we launch FCEV cars, how much is the life of fuel cell before needing to be replaced in L.V.?

HYDROGEN AS BATTERIES : New concept : HYDROGEN BATTERIES. Electric vehicles must switch to use hydrogen batteries instead of chemical batteries. People often think about hydrogen as fuel, but many forget that hydrogen is not only a fuel, but also very good battery, too. 1/ The fundamental science dictates essential truth of all chemical batteries : (CAREFULLY RESEARCHED STUDIES) if a chemical energy storing mechanism is charged as quickly as producing hydrogen, then this mechanism PRACTICALLY CANNOT HAVE BETTER ENERGY CONVERSION RATIO THAN ELECTROLYSIS PROCESS. Besides, it is possible to SETUP and adjust electrolysis reaction speed (for example slow down speed) to reach energy conversion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in AEROBIC earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries. 2/ New concept : hydrogen battery = (fuel cell + hydrogen storage object). The most simple hydrogen battery = 1 fuel cell + 1 compressed hydrogen balloon 300bar, can easily beat best lithium batteries by all features : more capacity, more power, less weight, forever lifespan, no degradation, charging in 5 minutes, same or better energy conversion ratio, but just noremarkable bigger volume sized than lithium batteries. 3/ So just equip electric vehicles with hydrogen batteries instead of chemical batteries. And equip hydrogen filling stations with mobile electrolysers to produce compressed hydrogen 300+ bar on site from electrical outlets. Electrolysing hydrogen filling stations (hydrogen battery charging stations) can run electrolysers from electrical outlets to produce liquid hydrogen on site, to avoid suddenly leap change requirements for big number of already existing current liquid hydrogen cars in the markets. But liquid hydrogen has low energy conversion ratio. For now and near future, compressed hydrogen (produced on site) is more versatile for various applications. (Additionally envisagedly, owners of ANY SMALL COMPRESSED HYDROGEN MOBILITY VEHICLES/ROBOTS/BIG DRONES/MOBILITY DEVICES can buy small mobile household electrolysers to recharge hydrogen batteries at home at night/any times). 4/ Example and comparison : hydrogen cars vs battery cars, hydrogen batteries vs chemical batteries : The old approach sets high H2 cost because : they pay for making H2, then they pay much for converting H2 to liquid H2, then they pay much for transporting liquid H2 by trucks (complex safety trucks, and very small weight of liquid H2 on every trucks), then they pay for keeping cryogen conditions to store liquid H2. But in new approach of ‘electrolysing hydrogen filling station” : you use electricity from electrical outlets at electrolysing hydrogen filling stations to run electrolysers to produce compressed hydrogen 300+bar on site. So you pay only for electricity and water of course. No other fees. No complex cryogen equipments. Compare : hydrogen batteries vs lithium batteries in the approach of “electrolysing hydrogen filling station” : 4.1/ Grid transmission loss : hydrogen battery charging and lithium battery charging onsite cause same grid transmission losses. Conclusion : Equal. 4.2/ Energy conversion ratio in charging : (electric energy -> chemical energy) Electrolysers in quick mode (very high electrolysis reaction speed) have energy conversion ratio about 70%. Lithium batteries quick charging has energy conversion ratio about 60-70%. Electrolysers in slow mode (small electrolysis reaction speed) have energy conversion ratio 90%. Lithium batteries slow charging has energy conversion ratio 90%. Conclusion : electrolysers win, because of the ability of flexible modes of scheduling and functioning to reach higher energy conversion ratio. 4.3/ Energy conversion ratio in performance : (chemical energy -> electric energy) Fuel cell has energy conversion ratio about 75+% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 70-% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat. Fuel cell has energy conversion ratio about 85+% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 95-% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat. Conclusion : Equal. 4.4/ Energy loss in energy packing compressing process : Hydrogen battery using compressed H2 300bar cause about 3-5% energy loss for compression. But hydrogen battery weight is very small. Lithium battery loses 0 energy in compression. But lithium battery weight IS INHERENTLY HIGH. That means you always need to transport noneccessary lithium battery heavy weights on your vehicles every seconds. -> The higher power category, the higher loss with lithium batteries. The longer range, the higher loss with lithium batteries. Conclusion : hydrogen batteries win with big advantages 4.5/ Spatial size : Simple hydrogen battery = 1 fuel cell + 1 hydrogen ballon 300+ bar. For small capacity category (for example, passenger cars capacity category) : simple hydrogen batteries have little bigger spatial sizes than lithium batteries. For nosmall capacity category : simple hydrogen batteries have little smaller spatial sizes than lithium batteries. Conclusion : lithium batteries win with nobig advantage. 4.6/ Lifespan and degradation : Hydrogen batteries have practically forever life span, and practically no degradation. Lithium batteries have lifespan about 3 years. Some good ones have 5 years. Other modern modified lithium batteries have more lifespan but smaller capacities. But all of them degrade every year. Conclusion : hydrogen batteries win. 4.7/ Influence of environment temperature : Hydrogen batteries never fear environment temperatures. Lithium batteries fear environment temperature. Even in some seasons you can not or you ineffectively use lithium batteries. Conclusion : hydrogen batteries win. 4.8/ Charging time : Hydrogen batteries : load compressed Hydrogen 300+bar or exchange compressed hydrogen canisters 300 bar in 3-5 minutes. But you must waste minimal 30 minutes for nofull charging lithium batteries, and often you must waste some money for paying some unnecessary things in fool waiting times too. -> waste time + waste money. Conclusion : hydrogen batteries win. 4.9/ Synchronize with grid supplying schedules : Electrolysing hydrogen filling stations can easily pick up flexible schedules to run electrolysers in tandem with grid supplying schedules. So Electrolysing hydrogen filling stations can pick up right hours of day for incentives electrical tarif. Nets of electrolysing hydrogen filling stations ideally use intermittent clean energy/renewable energy. But electric charging stations can not pick up times. High power electric charging stations terribly conflict with intermittent schedules of clean energy/renewable energy. The more higher power electric charging station in quick charging mode, the more terribly it conflicts with intermittent energy supply schedules of clean energy/renewable energy. Conclusion : hydrogen batteries win. FINAL NATURE TRUTH VERDICT : HYDROGEN CARS WIN MANYFOLD AGAINST BATTERY CARS. Just need to make right approach : model of distributed hydrogen productions onsite (nets of distributed ELECTROLYSING hydrogen filling stations) + electric cars with hydrogen batteries EXACTLY MAKES HYDROGEN CARS MORE ENERGY SAVING THAN BATTERY CARS, AND IDEALLY COOPERATES WITH INTERMITTENT CLEAN ENERGY/RENEWABLE ENERGY THROUGH ALREADY EXISTING ELECTRICAL GRIDS. All new electric vehicle manufactures, which make/begin making electric vehicles, need to choose hydrogen batteries and cooperate to build nets of hydrogen battery charging stations (nets of electrolysing hydrogen filling stations are easy), for getting advantages of initiating, for their profits, for environment for AEROBIC orienting breath air for world

.hydrogen cars can really ECONOMISE MORE FUEL COST THAN ELECTRIC CARS IF WE MODIFY OUR CURRENT HYDROGEN DISTRIBUTION APPROACH ! The biggest cause of hydrogen cost is that WE TRANSPORT HYDROGEN BY TRUCKS, IT IS EXPENSIVE. Just try to avoid to transport hydrogen by trucks, then hydrogen will be very cheap. It means that NEED TO PRODUCE HYDROGEN ON SITES (WHERE FILLING HYDROGEN), OR TRANSPORT HYDROGEN BY PIPE LINES. So we need to make 1 or 4modifications : 1/ Distributed hydrogen production on sites : hydrogen filling stations should be equipped with electrolysers, so hydrogen filling stations can produce hydrogen on sites from electricity outlets, instead of just receiving hydrogen from other places. Thus avoid problem cost of transfer hydrogen by trucks. Besides, nets of electrolysing hydrogen filling stations are ideal solution/market for intermittent renewable energy. It is new worldwide coming hydrogen distribution approach, so it opens markets of mobile small sized electrolysers. Electrolysers are not so expensive for hydrogen filling stations. 2/ Use compressed gas hydrogen batteries with mini household electrolysers/mini mobile electrolysers : small mobility vehicles/mobility machines/mobility robots/mobility drones …, will use hydrogen gas batteries (hydrogen gas battery =hydrogen fuel cell + compressed hydrogen gas ballon 200-300 bar). And each of these mobility machines can be sale with mini home electrolysers, so that owners can produce to fill hydrogen at homes (charge hydrogen batteries at home). Hydrogen ballon 300bar is enough, so that hydrogen battery 300bar(fuel cell +hydrogen ballon 300bar) can guarantee more energy capacity than best lithium batteries, and it guarantees that the size of hydrogen battery 300bar is not remarkable bigger than lithium battery of equivalent energy capacity. Of course 700bar allows more hydrogen storages, liquid hydrogen allows more hydrogen storage. But for hydrogen batteries, gas hydrogen ballons 300 bar are enough for balance of performance-capacity-size-energy convertion ratio-ballon material-simplicity. Hydrogen batteries 300bar + mini mobile electrolysers are ideal for two-wheel vehicles/small cars/small robots/drones and for trend of hydrogen mobility devices anywhere (easy to operate anywhere and easy to charge anywhere with electricity). 3/ hydrogen batteries for big station energy storage : Independent hydrogen batteries (hydrogen fuel cell + compressed hydrogen ballons > 300bar) + independent electrolyser is best variant. when excess energy, then run independent electrolyser. When need electricity, then run independent fuel cell. And intrigued working mechanism between independent fuel cell and independent electrolyser. That is all ! No complex automatic control system. 4/ hydrogen filling stations need to prefer using hydrogen pipe line than transporting hydrogen by trucks. 5/ The fundamental science dictates essential truth advantages of hydrogen. Science : if a chemical energy storage mechanism is charged as quick as producing hydrogen, then this mechanism PRACTICALLY CANNOT HAVE ENERGY CONVERTION RATIO BETTER THAN ELECTROLYSIS PROCESS. Besides, it is possible to adjust electrolysis reaction speed to get energy convertion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries

Hydrogen makes zero sense for light duty vehicles. Heavy duty vehicles > 350 miles, it probably makes sense. Why does Toyota push this nonsense.

This is wonderful, thank you! Will be following up on this conversation as I interview Jackie Birdsall on my Seeking Sustainability LIVE talkshow this morning - exciting future tech!

Hydrogen produced by electrolysis is the perfect companion for the cheap totally safe waste (plutonium) consuming nuclear power plants of the next generation of nuclear power plants. The important feature of these power plants is that the pressurised water method of cooling the reaction is eschewed. Molten salt reactors may be the ultimate goal here. But MOLTEX has a "stable salt reactor" ready for deployment.

I agree that out in the open, any hydrogen which escapes from confinement is going to go straight up in the air, and ultimately escape from the earth's pull. But in enclosed spaces, such as underground parking areas or in tunnels, an accumulation of hydrogen which cannot escape upwards is definitely going to spoil somebody's day.

Fcel the best guys,by the time will past plug,,fcel real future🤫🤫🤫

will invest in Plug Power.

Can't know how I stopmed onto this. Anyway Awesome content ❤️. I also have been watching those rather similar from mStarTutorials and kinda wonder how you guys create these vids. MStar Tutorials also had cool info about similiar make money online things on his channel.

PLUG POWER! #1

Post from Canada: Could someone answer the following please? * the comparative energy densities between Fuel cell Hydrogen and Electric Vehicles (Gravimetric to be specific) ? * the maintenance involved in Fuel Cell Vehicles especially the Fuel Cell and how expensive is it? * the cost benefits of transporting H2 as Ammonia Vs compressed H2? What would be the energy density we would be compromising with the cost. * What is stopping us right now from using compressed H2/Fuel Cell in Airplanes? I know there are already long range inspection drones operational.

You need clean point of use hydrogen generation from methane. In the home , at the gas station. Embrace NG , its pipes are this countries vascular system.

The cogen boiler from veissmann is bad ass . Unfortunately I can't even try to sell one in the US.

Like all these green new deal plans this is not feasible economically, nor is it technologically plausible...of course it all sounds good, but so does Willy Wonka's chocolate factory...To create enough hydrogen to replace oil would take over 4 times the energy now produced in the world, a truly staggering figure, and the cost is well over 50 trillion dollars, perhaps even as much as twice that...that would be if we had the materials that would actually work in a reliable way, which we don't, hydrogen embrittlement and the tendency of hydrogen to leak can not be ignored...this is pie in the sky fantasy...

Excellent !!!
