Here in Canada, we dump electricity daily during low uses periods for hydro generators and when we power down our reactors. During these periods, we pay our U.S. neighbours to take our electricity surplus because the problem is that our system have no storage capacity. Compress liquid hydrogen and the fuel cell will solve that. Lithium batteries are expensive, bulky and degrade over short periods of time which is why industry such as hospitals that require a constant reliable source of electricity still use diesel generators as a backup. The amount of time hydrogen can be stored is limitless which is why no company has abandoned r&d. The question is not how to use it but rather when will it be implemented.

Germany has 91 Hydrogen stations, 16 in progress of being built and at least one regional train line with Hydrogen train in operation. And you've forgot to mention biggest interest group in Hydrogen - Metallurgy - who are looking at hydrogen as a material for zero carbon Steel production

A plane flying with hydrogen as a fuel would be a sight to see.

I've been seeing quite a few Nexo's here in S.Korea despite the lack of infrastructure. I live in the present, hence Kia Soul EV.

You have to change the FPS you’re filming at so you don’t get the light flicker in the blue backlight

These are the early signs that the oil companies and oil-rich countries will soon go out of business! ⚠️

The main problem for hydrogen is thermodynamics, don't see getting around that one any time soon. There will be a large hydrogen market but not for road transport BEV's are cheaper and easier and will remain so.

The most amazing part about hydrogen fuel cells is taking excess renewable energy and creating hydrogen which can be stored as a giant battery. That hydrogen can be used in a fuel cell to create electricity or be pumped directly into hydrogen vehicles. Bloom Energy will lead the way in hydrogen fuel cells.

Nice video, but you missed a revolutionary new H2 Invention from the Fraunhofer Institute in Dresden. They extract H2 into a grey paste wich is filled in small plastic cartridges (like silicone cartridge for the home usage). It could be storaged at room temperature and normal atmosheric pressure instead of 70000MPa. You could sell the cartridges at regular gas stations. You only need to fill in additional water for the Fuel cell process. Only disadvantage: you need additional Magnesium for the Paste, which production is also not fully green yet, but it solve the H2 storage, pressure and temperature issue.

In the canary islands there is a project to produce Green hydrogen with marine wind farms, I hope it's not a boondoggle and works

This was a bit underwhelming. There's more things you can do with hydrogen - you can for example mix it with natural gas and make your home heating more ecological until we have better solution and so on.

thanks, thats exactly saying everyone when having the electric vs. hydrogen conversation with someone

Herbert Diess, CEO of German automaker Volkswagen, has struck down any thought that his company will take the hydrogen fuel cell path, claiming in an interview with Financial Times that the technology will never work well enough to deliver on the promise of an alternative clean energy source to battery power.

Someone told me hydrogen would replace ICE cars 30 years ago. Still waiting....

The regional trainline in my area is switching form diesel to hydrogen (until 2022/23), produced form water with electricity form a hydroelectric dam.

It's a good alternative, I've been hearing about it's potential for 20 years.

Chile is currently going full Hydrogen since they discovered they are basically the gods of possible Green Hydrogen production, just like they did with Copper edit: And Solar, obviously, how could I forget, just to name Cerro Dominador

All forms of clean generation and storage should be on the table. What works best for each unique region will get sorted out. On Hawai'i they have a deep geothermal well that can produce unlimited clean H2. There will be no single solution. Throw it all at the wall and see what sticks.

I think we should go in the direction of smaller forms of transport be electric, larger forms of transport (Trains, ships, planes) be hydrogen, and hydrogen mainly be used for powering the grid.

Always liked Hydrogen Fuel cells. In practice, it seems like a more easily implemented concept with fewer tradeoffs. Hope we do get an affordable car with this design or more incentives to develope it further.

hydrogen has a few drawbacks, 1 being that it is expensive to generate, 2. that it has a energy/volume ratio, meaning that you need a lot of space to store it, you're effectively going to have to change the the design of Airplanes or limit their range. 3. It is difficult to manage, leaks easily and also goes boom. and 4. It is the primary greenhouse gas, so it contributes more to warming than C02 (often forgotten)..

Chilean goverment its going full hydrogen on energy policy

This has been the question for over 20 years

I am a little skeptical in seeing hydrogen used in personal cars, but I could see it being used in commercial shipping and air travel. I could also see many factories using it as a fuel for their electric needs. Unfortunately, green hydrogen production/storage will probably only have a limited availability to areas with very large bodies of water. Agriculture sectors would have some concerns using lakes and rivers to make hydrogen fuel much like many of their concerns about hydroelectric dams. There could be a market, but it will most likely be regional and niche.

We're seeing a growing focus on building green hydrogen factories where I live in Northern Norway nearly all our energy production is hydroelectric meanwhile we have about 40% energy surplus. Our diesel ferries are replaced with hydrogen ferries and there's talks about getting hydrogen trains as electrification is quite expensive

I have been writing to world environment ministers to adapt H². Thanks for the supporting true video

The problem for hydrogen is that cheaper energy doesn’t help it beat lecturing vehicles. The key is to improve storage technology and reduce the amount of power needed to produce. And you need to improve those faster than battery technology improves.

You guys can check the alcohol fuel cell being developed in Brazil 100% renewable

I live in the western USA, the land of big pickup trucks. A quick trip into town could rack up 200 miles. Out here the race is between battery pickups and potentially hydrogen pickup. If hydrogen is going to make it, then this is the place to try. But then again maybe biodiesel. What ever, it will have to be cowboy manly.

finally people are talking about what I talked about since before tesla was a thing

seems like your list of sources of hydrogen overlooked a rather important one: hydrogen produced from Nuclear Energy using SMRs, either by thermolysis or high-temperature electrolysis, likely to work out cheaper than 'green' hydrogen, and predicted by some to even become cheaper than 'grey' hydrogen at large scales

Putting all our eggs in one basket is not a great idea so both hydrogen and electric should be developed. To make sure we have enough energy to develop them we can’t abandon nuclear.

No! Where are you going to get the hydrogen? Where are you going to get the energy to extract hydrogen?

I am a chemist. I disagree. The main obstacle is fuel cells. Just like fusion reactor, the robust fuel cell will always be 10 years away. Until there is a major breakthrough in fuel cell technology, of course. We can produce and store hydrogen pretty well but not generate electricity from it. Battery wins and I do not see how it can lose in the next 30 years.

Hydrogen's biggest challenge is how much space it take to store. For land and air transportation, more volume means more drag and that kills efficiency. Even storing it as a liquid , the volumetric energy density for hydrogen is EXTREMELY low and storing it as a liquid is not easy to do. See all the problems the SLS has been having because it uses liquid hydrogen as a fuel - which is why SpaceX and other rocket manufacturers have moved to Methane. Liquid Hydrogen takes four times as much space as gasoline to store the same energy and then you have to consider all the challenges of how to store it as a liquid - which is literally rocket science. I think it would be way more practical to do like SpaceX is doing and use liquid Methane. Just like hydrogen, you can make methane from electricity using the Sabatier process and it is already widely used and stored (Methane is basically the same as LNG) and, when made using the Sabatier process, it is carbon neutral.

Put a hydrogen tank and fuel cell in the frunk and you have a perfect hybrid. Battery for work, hydrogen for travel.

Hydrogen is not a fuel, hydrogen is a storage medium

For big trucks and busses, the electric grid cannot feed them all at the same time. The weight of the bateries is also making hydrogen the best solution for larger vehicles. For motorcycles and small cars, bateries seems to be cheaper and more practical.

Hydrogen is NOT a source of energy, any more than a battery is. It is a storage medium. Currently, putting 1 kWh of electricity into a fuel cell yields around 0.3 kWh of usable energy in your car, while a battery gives you over 0.9 kWh. H2 will be used where batteries can't be used, for whatever reason. The cost of H2 will be 70% of the input energy wasted. The first battery powered electric aircraft are already in commercial use.

I think hydrogen makes sense for storing excess energy from renewables, or to fuel airplanes (because batteries are heavy for them). but it is not good to use for cars because energy is lost by using electricity to separate hydrogen from water and converting it back to electricity in fuel cells. also hydrogen would be good for ships that travel long distances.

The EU started a project called the hydrogen strategy to transform its industry towards this route. The political will is there, the money is going to be spend. I think hydrogen is a far more elegant technology than batteries or fossil fuels. Its use is much more diverse and it is safer than the alternatives.

Why don't we use natural gas instead of hydrogen for cars?

I had high hope for hydrogen about 30 years ago, but it became clear 20 years ago that battery technology would win. It takes about 3 times a much energy along the full supply chain to travel a mile on H2 vs. BEV. If you carbon capture fossil fuel derived H2 the cost goes up by 4 to 10 times. While every one keeps saying in the future H2 will be so much better, they are assuming batteries will remain unchanged. Long before H2 become viable and cost effective BEV will change in minutes and have nearly 1k mi range on a charge. Battery technology will also be working for trucks, boats and planes by then. There is only one area I think H2 might be useful, and that is in places that have sever shortages of water and the cost of water is very high. Put an off-shore wind farm with floating wave generators carrying solar panels and maybe some tidal generation under water. Us that energy to get H2 through electrolysis. Then use a fuel cell to get back to electricity. Use the waste heat for more electric generation. Send the electricity and clean water back to shore. The electricity will be too expensive, but the cost will be offset by the clean waste water of the process.

Fuel cell cars?-No, it will be batteries. Fuel cell Ships, planes? Yes. Wind and Solar often produce electricity that needs a storage option. Batteries are only short term storage- so, long term storage: Hydrogen. So, Platinum is a good investment today as it is needed in green Hydrogen production.

With respect ... I'm totally unconvinced. Storage is a major issue. Basically either: extremely high pressure in heavy tanks (useless for airplanes) or cryogenically at 20.28K (useless for cars/trucks etc.) Either way it is probably too inefficient for ships. In addition to safety issues, making storage impractical in populated areas. Transport, either by truck or pipeline, would be expensive and dangerous. Production is, and far into the future will be, from mainly dirty fossil fuel sources, because converting it to and from water is expensive and inefficient. In practice, it usually needs to be converted to electricity using fuel cells, which require extremely expensive catalysts, such as platinum. Also as you mentioned, it would require a massively expensive infrastructure, for something with very little appeal. Politically difficult? Just to rub it in, I should note that even Elon Musk has abandoned it ... as a rocket fuel! As tantalizing as hydrogen may seem, it's adoption as a fuel is probably mostly being pushed by a despicable fossil fuel industry, grasping for any sort of straw, to make themselves appear a bit 'greener' and more palatable to the skeptical general public. As usual though, this is at best, very misleading.

Hydrogen is really about long term energy storage not transportation. It fits into the scheme where we go 100% renewable and need something to deal with intermittency over long periods of time.

Oil has hydrogen and carbon. A series of carbon atoms are used to bind hydrogen atoms. Solid-state hydrogen storage can use fine iron powder to loosely bind hydrogen atoms.

Hydrogen made by electrolysis uses 3-4 times more electricity than using that electricity to charge electric vehicles for road transport.

you are wrong on the long haul electric bus, in Sydney Australia they are as we speak testing not 1 but 2 different electric buses. They originally expected to have to charge the buses every day or after 1 or 2 shifts. What they are finding is thanks to the regenerative braking the buses are lasting 2-3 days between charges. And the buses on trial are actually using older designed lithium batteries with newer and more efficient batteries expected in the final role out.

Only questions...no answers👍

It’s a difficult proposition. It comes down to energy density, and the problems of generating hydrogen. Electrolysis takes a lot of electricity and for every water molecule you break, you get one hydrogen atom. Deuterium is better in terms of energy density, but making deuterium in industrial quantities isn’t going to be cheap or easy.

Very interesting. You only forgot to mention one very important point, what does S.Korea and Japan have incommon? They are both technologically advanced, yes but most importantly they have got no natural resources whatsoever(oil or coal), so for them it is a very promising technology. I hope they succeed with it.

There are other technologies for producing green hydrogen besides using electrolyzers. Think about algae and bacteria. Another very promising technology is mimicking how plants work, called artificial photosynthesis. Maybe a great topic for a new VisualPolitik EN video.

As you mentioning it's use in metallurgy suggests, _green_ hydrogen could be great for green steel. I would have liked to hear more about that instead of the hydrogen car. Since, you see, the important "detail" missing in the video is that unfortunately hydrogen is not very energy efficient compared to batteries for passenger cars (roughly half, well-to-wheel at 30-40% vs. 60-80%). Paying the energy cost of using hydrogen only makes sense for long haul / heavy payload vehicles.

Hydrogen has a darker side too. Leaks (at the surface) of the gas would over time, reach and slowly accumulate in Earth’s upper atmosphere, where it could start to alter the very sensitive chemistries of these layers. People qualified to warn us of these issues have done so before. It’s troubling that very few people seem to care to know or talk about these things, and always talk about clean hydrogen. Yes, “Clean” also has a cost.

A sizeable portion of São Paulo city's bus fleet is hydrogen-based already, one of the first widespread uses of this type in the world

Imagine if someone ruptures the hydrogen tank on our car.

I'm definitely rooting for the hydrogen revolution. Thanks for the vid

Lots of buses in Tokyo run with hydrogen already. However the Mirai is not selling well. Need more infrastructure.

In the 60's they were looking at storing Hydrogen in vehicles in Hydriyd form.

I am not sure about consumer vehicles but commercial vehicles of all kinds like Buses, Trucks, Ships, Planes etc are going to use Hydrogen in future. Another green way of commercially producing hydrogen would be BioFuels, BioFuels like Biodiesel can be used in Biodiesel generators and then we can use carbon capture technology to stop harmful emissions generated from biodiesel generators, the power and electricity generated from Biodiesel generators can be used for electrolysis of water to produce hydrogen which can be used in most commercial/consumer vehicles and other industrial applications. BioDiesel is more environmental friendly alternative to fossil fuels.

While In Denmark, electricity is produced from renewables, most of the world will take many years to decarbonize electricity production. In countries such as Poland, China, or apparently Germany (in cloudy day with little wind, Germany has to compensate drop in renewable energy, by using coal/gas), these electric cars run on electricity produced from coal. Hydrogene is much more ecological solution for such countries

Tesla has already successfully implemented a way of storing excess electricity through the use of lithium ion batteries in South Australia. Using a battery seems more practical as a source of reserve electricity, since you physically have to transport hydrogen after it is manufactured to where reserve power is needed - or to a hydrogen powerplant. A large battery could store that energy easier and kick in and supply the needed reserve energy easier.

I'm no expert on the subject, so I don't have enough argument to vote in favor of hydrogen or Electric power, but it was indeed an interesting video and it made me want to research more on these topics, so I will come back to leave an opinion in a couple of days. Thanks for the video!!

For urban households electric cars is a no brainer as they can be "refilled" at home without dependency on expensive infrastructures(fueling station)

My problem with battery cars is that it requires a lot of lithium Lithium is rare. It will breed new wars, where one country invades another for lithium, just like oil

Your definition of Blue H2 is slightly wrong. Only by producing H2 from Natural Gas, it doesn't become Blue H2

If there is no infrastructure then having a hydrogen car will be expensive

The problem seems to be the amount of energy needed to produce hydrogen. But there is a technology that uses very low amps and produces 44,000 btu's . It produces hydrogen at a very low cost. It would make hydrogen economical enough to be better choice .

For Gods sake, please fix these annoying volume spikes!

1:16 Fusion. Using black holes to form kugelblitz batteries. Fusing neutron stars into strange matter stars (strange matter has negative mass")

Electricity is, not hydrogen. It only is viable in VERY remote areas where you can't get an electrical outlet, but you can put a big gas tank for refueling.

Re cost : not mrntioned was that sometimes renewable energy is thrown away when production is more than demand. So that cost is nearer zero.

Nice sales pitch, but what about Electrolysis ? Consider EPOCH HHO on this channel.

There were hydrogen aircraft in the 1930s. One of them was called The Hindenburg.

2:56 Why the music from Powertrain is coming?

Other than the potential of unscrupulous dealers using H2 to greenwash their fossil fuels that you toughed on, one of the other major problems with H2 is its total efficiency. For example, electrolysis of water loses 20-30% of electrical energy pulled from the source compared to about 10-15 for charging a battery

Our currant rate of energy consumption makes it nearly impossible for renewable energy sources to sustainably meet demand. The future energy market might be more diverse though🤔

On paper this sounds reasonable. But what about all the safety concerns. Hindenburg burned nice and bright.

As the seas rise we may find it necessary to process hydrogen from sea water

And not a word on efficiency. 50-60% of electricity is dispersed as heat on electrolysis and fuel cell cycle. Hydrogen is peddled by mineral extraction companies as another application of gas and coal. Can not refuel hydrogen car at home like an electric one. Corporations keep dictating prices just like they do now with gasoline. What a wonderful technology... for them.

current petrol stations can be converted to hydrogen stations, meaning unlike electric infrastructure, conversion of current infrastructure already in use is surely quicker and easier than building new infrastructure, so it is a matter of car manufacturers building and offering hydrogen options

I put forth the idea of putting wind-turbines on un-used platforms in the Gulf of Mexico, convert Ocean water by Electrolysis to hydrogen, store it in a floating LPG (type) tanker. When full, swap it out with another tanker. THAT WAS IN 2002!

Elon musk said hydrogen fuel is “mind boggingly stupid” , when asked about hydrogen as alternative fuel for EV.

Necessity is the mother of invention There is a catch for electric car India does not have lithium unless someone develops a battery with common sources there is lot of new research is ongoing in india And for hydrogen it looks good if india can make it successful bcz we also do not have oil and we consume a lot means we need change in hydrogen india also doing research if we get reasonable outcome hydrogen is more acceptable by indian consumers

10:40 The cost is only getting lower, because there are not enough storage systems.

At 7:50 its pronounced as met•hane gas not "me•think" gas.

always is and can be used in ice cars via conversions

Bus hump is usually air conditioning... 12:24

Germany allocated about 9 billion € to develop the hydrogen industry, and France committed 7 billion € as part of their stimulus packages. This video makes "green hydrogen" look like a research project, while it's already in the early process of industrialization and will take off in the coming years

Hydrogen electrolysis has just reached 90% circa Dec 2020 - Green Hydrogen Systems (Denmark). Also consider Volcanic Geothermal and Tidal generation joining Wind and Solar, both are around 2 cent/kWh. Remember Li-Ion battery is at $120/kWh now.. March 2021. And Hydrogen has about 100X more Energy Density than current Li-Ion batteries even after the inefficiency of the PEM Fuel Cell (circa 60%).

it's going to end up used almost only for ships, planes, and long haul trucking. grid storage to some extent, but there is also things like compressed air that work with roughly the same efficiency and would be cheaper up front to construct for practically the same gains. so who knows. though it will (I would bet) see wide spread military adoption in place of petroleum fuels. probably wouldn't even be a hard sell to the military. "if you can secure a water source and an energy source, you can make your own fuel on base. and if not, still bring it in, the same way you always have"

I had heard roughly 30 years ago that's someone had devised a method of producing hydrogen by taking a spool of aluminum wire, passing it through water in a tank, and generating an current down the wire. The electricity makes the hydrogen and oxygen in the water split and the oxygen binds to the aluminum forming aluminum dioxide keeping it from rebonding to the hydrogen. The hydrogen then rises to the top in yhe tank to be used as fuel. Supposedly the petroleum companies bought out the patent in the 1970s and suppressed the technology.

Although fuel cells are twice as fuel efficient as combustion engines and gas turbines, it would be wise to use "normal" cars at first. It is very easy to adapt combustion engine technology for hydrogen use, it is even possible to convert existing cars to fighter burn hydrogen or gasoline. Use existing combustion engine technology, while fuel cell costs are coming dow. During that time you have to massively invest into hydrogen refueling stations and people can immediately use their combustion engine cars after a short and cheap refit. By the time you have the infrastructure to produce and distribute hydrogen in massive and cheap amounts it is time to switch to very efficient fuel cells, instead of combustion engines. Such an approach is best undertaken in a densely populated city with high incomes, like NYC, Dubai or similar cities. Once the practical feasibility is prove, hydrogen is ready for widespread use.

All of this gets thrown out the window when a company figures out a highly efficient filter that can use gasoline but produce minimal pollutants. Strangely enough much of this hydrogen tech will only be affordable to rich countries. The countries that are doing the most pollution are considerably poorer and wouldn't be able to afford these devices. On top of this, it would significantly drive down the price of traditional vehicles which those poorer people would then purchase. I'm not against the technology, but people need to understand the practical and pragmatic impacts this change will have. Sadly, when this is brought up it's dismissed despite being a serious issue of concern.

The cost of renewable energy has gone down remarkably in ten years, the issue is now intermittency. Green hydrogen storage is an absolute must if we are to avert ecological catastrophe.

Have you actually stood near hydrogen being ignited. It blew me off my feet. I don't think people know how dangerous hydrogen is. I can tell you, I would never travel in a hydrogen vehicle or be near one, knowing how explosive or how easily it ignites. Also producing hydrogen is very inefficient, these losses must be added into the total efficiency of hydrogen. I'm just waiting for the first hydrogen vehicle to be in an accident that ruptures and ignites a storage tank... a huge explosion that will take out 3 city blocks from one car. It is something, I and others would not like to experience.

then is their any way for the hydrogen to be reconstituted into the water cycle or does it remain as waste product after use?

I must complement you on your presentation content, skills, and the video and audio material. My humble opinion is that cars will be battery powered in the medium term, and that larger vehicles and aircraft will be hydrogen powered in the shorter term.
