U.S. develops hydrogen tank

87
The US Army is developing new hydrogen-powered combat vehicles. In the future, the US armed forces will receive not only armored vehicles, but also BMP and Tanks.





United States Armed Forces are developing promising hydrogen fuel cell combat vehicles. The list includes infantry fighting vehicles and tanks, and the development is led by scientists from the US Army Combat Capability Management Center (GVSC) and the Ground Forces Research Laboratory.

According to new data from the Center for Land Vehicles, the US Army is engaged in an in-depth study and evaluation of fuel cell energy technology. Scientists expect that new developments will provide Washington with tactical advantages when using land vehicles.

Fuel cells generate electricity almost silently, efficiently and do not cause increased harm to the environment. Their energy efficiency is higher than that of internal combustion engines, and the hydrogen used as fuel can come from various sources: it can be produced from any water-based liquid, such as coffee, sports drinks or even urine. Moreover, existing fuels such as gasoline, propane and natural gas can also be used to extract hydrogen.

Hydrogen is the most common element on the planet. Potentially, many scientists see it as a future replacement for gasoline and diesel fuel.

The challenge is to reduce oil dependence


Although the latest hydrogen fuel cell technologies are expected to reduce environmental damage in the long run, they are primarily aimed at reducing oil dependence. In addition, the technology provides an important element of stealth: machines, on hydrogen, do not produce smoke, noticeable noise or smell, do not emit significant amounts of heat.

Scientists from commercial companies working for the army are currently developing unified hydrogen platforms to create the future tank and infantry fighting vehicle.

The new hydrogen power unit provides a number of advantages, including high torque, which should allow the future tank to overcome uneven terrain; quiet mobility; reduced acoustic and thermal characteristics; weight reduction of a combat vehicle; the possibility of obtaining fuel from several sources. But at the same time, a separate issue is related to security.

            The problem here is different - hydrogen engines have been worked on for a long time and as a result we have found out the most unpleasant thing - when hydrogen burns, suitable temperature conditions are created for the reaction of oxygen with ... nitrogen, with nitrogen !!!! At the same time, as for evil, such "cute" nitrogen oxides as NO2 (the same "fox's tail") and N2O (the same "laughing gas") are formed ... And the most piquant thing is that the reactions of oxygen with nitrogen do not begin It’s very difficult to compete with the reactions of oxygen and hydrogen, reducing the efficiency of a potential hydrogen engine very noticeably.
            So the pollution of the atmosphere from hydrogen energy will be worse than from "conventional" oil.

        Hydrogen engines have repeatedly tried to implement, there is technically nothing complicated. There are only three problems.
        Firstly, a source of hydrogen. It’s just that a cylinder with hydrogen loses to a gas tank - a gas tank of the same weight as a cylinder contains more energy, and takes up less space. And alkali metal hydrides will spend most of the energy received from the engine on the extraction of hydrogen.
        Secondly, explosiveness. The notorious catastrophes of the Zeppelin airship, the Kursk submarines, are due to hydrogen. But there were a lot of lesser known.
        Third, the price. Every kilowatt of energy received from a hydrogen engine is more expensive than gasoline.

        So most likely just another money laundering amid an increase in the army budget.

        Just a few questions! The first is that in the SGA diesel fuel (diesel) is over? Or did the states learn to produce hydrogen from nothing in the desert? Or did they learn to prevent the flow-outflow of hydrogen in technological processes? Or its conservation On board and bases? And such technogenic issues, not even the sea - OCEAN! For example, you all know how pure alcohol flows in the corners of the lips when you take it in its pure form, but pure hydrogen makes it ten times better through all the compounds that people invented, since its ATOM is less than EVERYTHING! So what they want is what they are developing! And we have hope for C-2-H-5-OH == (OUR)!

        Not really. They use the same natural gas and do not steam.
        There are two problems ... even three:
        1 - it is difficult to pump and store fuel,
        2 - energy storage density is very low,
        3 - superfluidity of hydrogen.

            For example, the Scourge effect. If you use it as a direct source of energy, the effect is one, but if as a current transducer is different. You can apply voltage of the same polarity to it, heat the gas, and there will be losses when the piston moves. And if the polarity is different, then the gas will cool. The piston will be
            also move, but at the same time generate heat all because of the same friction forces. This is not a perpetual motion machine. Just the efficiency will be higher, probably.

      Here's the thing.
      Americans are not going to carry liquefied hydrogen.
      This is both dangerous and not economically viable.
      They are going to use some kind of hydrogen compounds with either metals or non-metals.
      There are examples of such compounds - gaseous compounds with hydrogen form the majority of non-metals and some metals of the main subgroups:

      fluorine (HF), chlorine (HCl), bromine (HBr), iodine (HI), astatine (HAt), sulfur (H2S), selenium (H2Se), tellurium (H2Te), polonium (H2Po), nitrogen (NH3), phosphorus (PH3), arsenic (AsH3), antimony (SbH3), bismuth (BiH3, very unstable), carbon (CH4), silicon (SiH4), germanium (GeH4), tin (SnH4b, lead) B4H2).

      Unlike nitrogen, phosphorus and arsenic, but like antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes into elements even at room temperature. It is stable at temperatures below -60 ° C.
      Bismuthites are intermetallic compounds between bismuth and other metals.

      They will choose those that begin to decompose at high plus temperatures.
      And then the second stage.
      Hydrogen fuel cells.

      A hydrogen fuel cell generates electricity during an electrochemical reaction in which the atoms of the hydrogen supplied under pressure decompose into electrons and protons. Electrons enter the external circuit, an electric current is created. Then the protons pass through the membrane where oxygen and electrons combine with them. The only byproduct of this reaction is water vapor and heat.

      Unlike existing internal combustion engines, hydrogen fuel cell systems do not have moving parts, the loss of efficiency during operation is minimal.

      Here is such a horseradish with carrots.
      It is difficult and very expensive.
      Most likely - drank dough.

      Particularly encouraged by the Americans' concern for the environment.
      "Fuel cells generate electricity virtually silently, efficiently and are not environmentally friendly."

      Even weapons designed for completely non-humane purposes must take care of the rest of humanity.
      This is where the humanity of the US military has stepped.
      Our Shoigu and Gerasimov couldn’t even dream of such a break.

      About ten years ago, our "partners" filed a hydrogen storage program - they invented a composite cylinder with a pressure of> 600kg / cm ^ 2 ... I have a bad idea of ​​the results of damage to such a cylinder in TNT equivalent. wink

      Why on hydrogen, and not on shale gas? So at least it was a trend.

      Register a patent. There is a cylinder, there is a piston. And there is hydraulic fluid. There is no connecting rod and crankshaft, no gears and synchronizers. The piston of an internal combustion engine simply presses on the hydraulic fluid and it does the work where it is needed.

          Elementary. Spring. Cool scheme. But nowhere did I come across an info about works on such a scheme. But in fact, the efficiency should be higher. Yes, and do not need to be a monoblock. He scattered a dozen cylinders on the hull and the engine was ready. The main lines to connect.

      Well, you will not surprise anyone with a hydrogen engine, the question is rather in the price of hydrogen! While all these green technologies are much more expensive

        The article generally focuses on environmental friendliness and noiselessness. Figs with it - electric motors will really be quieter, but what will they do with the sounds of a shot? and the clang of caterpillars? And so on the seed, and why the tank silence ???
        And environmental friendliness - it’s better to launch hydrogen power plants, and the mass auto industry ... And then tanks, they will be built no more than a hundred ...

        War hurts people, but ecology doesn't care. There will be no man, there will be something else. And the Earth generally rubs its paws and says, "Yes, you finally kill each other. I still have so many unrealized plans."

      Trying to become a leader in oil production while building tanks that are independent of oil ... Logic. However. Another cut me like that. I remember that during World War II, gasoline for German tanks in many cases became a curse due to rapid ignition. And then hydrogen ...

        Who specifically is trying to become a leader in oil production ??? Russia was ahead of Saudi Arabia and became the second largest crude oil producer in the world. In the first place were the United States with an indicator of 11,658 million barrels of oil per day. In Russia, the average daily production was at the level of 10,738 million barrels, in Saudi Arabia - 10,643 million barrels.

      Hydrogen in the tank is an additional chance for the crew to fly into the air. It smacks of budget cuts. :-)

      The Germans created a seven on hydrogen at BMW. There was a direct mechanical symphony. Even small-scale production was attempted to be established or even adjusted. But they removed it from the assembly line and closed the project. Shaitanama explosive machine turned out.

      You can argue a lot. Just try your car on gas. Drive out into the field and then call a friend with a request to bring a canister with this gas, or else it’s over. And look at the reaction of this comrade.
