Update zur Wasserstoffpaste - Revolution in der Wasserstoffspeicherung

A little over a year ago I made a video on Fraunhofer Ivan's hydrogen paste and said that I think this is one of the most flagrant breakthroughs of our time and now it's time to

the research, there is currently an intensive search for new women in which hydrogen is stored Ammonia and boron nitrite, among other things, also play a role here, making up to 90% more energy efficient hydrogen bonding possible. what is the status of the hydrogen hope button? click subscribe now so you don't miss any more science videos and let's get started right now there is a lot of talk about hydrogen, even more than a few years ago and a lot has already been said about it for example now it has been decided that we will phase out hydrogen in the next few years.

You want to import Canada e However, the main problem in handling hydrogen remains transportation and storage. Hydrogen is usually stored in liquid form either at very high pressure or at very very low temperatures ie -250 degrees both are complex and expensive processes even in car tank hydrogen needs 700 atmospheric pressure times higher, so hydrogen tanks and cars are very big and heavy and the energy density advantages over lithium batteries are limited, for example in mobility and a big problem is the use of hydrogen paste , which could change transport or storage problems In the spring of 2021, the channel was about the so-called powerpaste It was developed by the Fraunhofer Institute and is considered a promising solution in terms of transporting hydrogen and to produce it, magnesium powder is hydrates in the first step, that is, the magnesium powder reacts with hydrogen for this, both substances are combined in a specified s by a pressure of about 6 bar, almost like a a large Thermomix which is under pressure and this creates magnesium hydride powder, the hydrogenated powder which is ground together with the carboxylic acid and the metal is placed in an agitator ball mill, resulting in a homogeneous mass with optimal conditions for transport and release of hydrogen The residue after the reaction is collected in an additional container and consists of magnesium hydroxide water and ester components and can be recycled It is mainly to recycle the magnesium hydroxide which constitutes the most Much of the paste can be processed and then used in other industries as recyclable material or simply turned back into magnesium.

What this magnesium could re-produce as a new paste is a cycle Mechanical energy is used to trigger chemical reactions, among other things, these ball mills are used for this and now I have said ball mill quite often, in the end it is a revolving drum in which small stainless steel balls are located and mechanical energy is released through rotation and vibration, which then reacts with chemical substances activates the method that is considered particularly sustainable and profitable because they are not used Solvents consume little energy and emit little CO2 in Australia there was also a mechanochemical breakthrough recently which was a big surprise but more about the optimal use of energy paste.

It is filled in air- and moisture-proof containers and can then be stored for several months or even a few years. The energy paste has a whopping energy density of 1.9 kilowatt hours per liter which is ten times the capacity of the erien lithium ion battery that means for the same mass the hydrogen paste stores ten times more energy to release the hydrogen from the paste simply has to be put in contact with water so that a truck with the paste does not have to go to a gas station but simply change the cartridge and add water. What is really evident is that half of the hydrogen generated is only created by the added water.

Of course, this is only roughly described now. If you'd like to take a closer look at the production and functions of the powerpaste, I'll link you to the video I made a year ago, I took a closer look at it in the video description, but why am I telling you all this again? At the end of 2021, a large powerpaste production plant was supposed to start and of course I followed it diligently and therefore also some of you wrote me messages on insta wan n the time has finally come, now I have asked the Fraunhofer Institute again and this is the result, so of course the research is not spared from all world events and due to the delays in deliveries due to the pandemic and the skyrocketing prices of raw materials, the production plant is unfortunately still not up to par, it is planned to be open until summer 2023, but then it should be ready, then in Braunschweig, where the plant is located, four tons of pasta will be produced energy per year then there will be a total of 6400 kilowatt hours of energy and the average electric car could drive around the world with it but and that's important today when I did the vi deo a year ago, powerpaste is not only particularly suitable for various small vehicles, but also for home use, for example and power paste then produce on a large scale at what price the energy paste will be available in the end, it is still not clear here, As almost everywhere, rising energy prices play an important role until the production plant opens, but other possible uses for powerpaste are also being worked on.

Together with the Grünland company, the Fraunhofer Institute has developed an emergency power generator for power outages in which a fuel cell generates power from hydrogen, which comes from the paste in the cartridges and is then fed to the cells. The reaction between energy paste and water can be easily turned on or off at the push of a button. In addition to paste, there are other research approaches to storing hydrogen. huge amounts of pollutants are rushing into the air that's what I was recently told about global traffic emitting 833 million tons of CO2 in 2021 that's more CO2 than all road traffic in Europe emits 784 million and that's why the research is working full steam ahead on emission-free fuel alternatives Ship FC has set itself the goal of storing hydrogen in the form of ammonia.
update zur wasserstoffpaste   revolution in der wasserstoffspeicherung
Ammonia is mainly composed of two substances, i.e. nitrogen and hydrogen, but in contrast to pure hydrogen, which must be stored and transported at -253 degrees or 700 bar, a temperature of -33 degrees or more is sufficient for ammonia. a pressure of 9 bar at +20 °C Ammonia is a super power reserve for real fuel hydrogen To obtain it, ammonia is first split into hydrogen and nitrogen on board and then fed into a fuel cell, then produced electricity, hydrogen is sold needs and remains pure water and nitrogen a catalyst prevents the formation of toxic gases and hydrogen and ammonia residues entering the environment with this technology, long voyages with large ships should also be reliably possible the first results should be next year when the Viking the energy put into the sea with the new propulsion is a second possibility is to obtain hydrogen from dust sodium boron hydride that's what the h2ships project is all about and the Neo Orbis with the 20 meter long ferry that is currently being built in Amsterdam and will be the first ship next year to drive a solid hydrogen compound for the drive, sodium boron hydride is first mixed with high level water and a stabilizer, then the mixture is passed through a catalyst and the hydrogen is released Possibility would be for example caustic soda with caustic soda as chemical agent and sodium borohydride as fuel.
Daimler Chrysler already operated a prototype car in the early 2000s. The stabilizer is consumed in the reaction and sodium metaborate remains, which can then be enriched again with hydrogen. After the reaction, the residue is recycled into new fuel. Another promising transportation option for hydrogen was found in Australia, almost by accident, because the researchers were actually looking for an alternative to petroleum distillation, but instead found the latest process to efficiently produce hydrogen. Drill nitrite dust is placed in a ball mill and hydrogen is fed into the mill as a gas. When the drum starts to spin, the balls collide with the dust and the wall of the drum. begins the chemical process by which the Pu This works particularly well because the born nitrite absorbs the gas and the proportion has a relatively large surface area, making this ball mill 90% more energy efficient than conventional methods. usual separation.
The process does not use harsh chemicals and the boron nitrite itself is a complicated top chemical it is so safe you can easily store it at home in general the powder can be transported easily and safely to release hydrogen it only needs to be heated in a vacuum another benefit of the powder being that it can be reused multiple times so there is no waste product. Also, the process is not only possible with hydrogen but with all kinds of gases. Of course, these new methods have their drawbacks as well, and that brings us to the big worldwide. made a breakthrough so far, but there's still a little bit of room for improvement here, because in the developed fuel cell not all of the hydrogen has been converted to energy and the fuel cell gap reactor, which fails to splitting all the ammonia, you are left behind, say, 100 millionths of the ammonia used, which of course is only a very small amount, but a full 12% of the hydrogen produced is not converted to electricity and therefore the efficiency of the fuel cell. it also goes down with pure hydrogen as fuel, they're about 60% efficient with ammonia so it's 51.5 to 57% if things go well and at this point of course very important here production and transportation and so The hydrogen part is not included in the calculation, this makes everything significantly lower again and also sodium boron hydride as fuel, since with the fair prototype the new Orbis would probably nte not the best.
The best solution because besides the question of how smart it is to use a water soluble fuel in a boat, there are other problems with sodium borohydride. In the first place, sodium hydride is a toxic substance that should not come into contact with the skin or organic tissues in order to be used as fuel, but large quantities of it would also have to be produced. On the other hand, sodium borohydride has a price market value of about €15 per kilogram, which actually rules out its large-scale use from the outset; However, oxygen paste and born nitrite definitely have the advantage of not requiring toxic chemicals.
However, the Australian-born nitrite powder is still in its infancy. It must first be seen how efficient everything is on an industrial scale. being able to control and release hydrogen mobile it will certainly take a while before this is implemented if you compare these new methods to current standard processes in pressure tanks or hydrogen cooling there is still a lot of energy to store and use today Transport partnerships and therefore less energy to use hydrogen with new methods store and transport low energy consumption and more energy is required to release the hydrogen and use it, so all methods have their advantages and disadvantages and the Fraunhofer Institute also says that current and future methods will coexist in hydrogen technology, so I personally remain totally enthusiastic about this technology and believe that it could still be a game changer, especially since hydrogen is experiencing a renaissance, at least when it comes to being more independent so they're going to store energy, and I think hydrogen paste p It could be really interesting depending on how everything plays out in the world.
Let's conclude that the

is being diligently researched and the first bigger system will be built soon which means there is quite a bit of movement behind it and I am very excited to see it all on the site, what do you personally think? So which of the methods do you think is better and has the Fraunhofer Institute already decided that we can visit you? What questions do you have? What can I take with me? I should and should ask people there and speaking of questions check out my new shorts channel where I now answer a short question from the community three times a week a video of which I already linked to here so It also goes to the channel.
If you like passing by, I'd be glad, take care.
