Researchers have developed a one-step method for recharging the hydrogen storage compound ammonia borane. The breakthrough further promotes the use of hydrogen as the fuel of the future for driving vehicles and other transportation systems.

 

In an article recently published in the prestigious journal Science, researchers from the Los Alamos National Laboratory and the University of Alabama, in collaboration with the US Department of Energy, describe significant progress in the research of hydrogen storage materials.

Hydrogen, in many respects, is the ideal fuel. It has a high energy content per unit mass, compared to oil, and it is also able to be used to operate a fuel cell which in turn can be used to fuel engines in a very clean way. On the other hand, hydrogen has a low energy content per unit volume, compared to oil (it is extremely light-weight and bulky). The challenge in the issue of hydrogen as a fuel is the ability to get a sufficient amount of the clean gas to enable engine operation for reasonable distances.

The research in this field has progressed towards the development of chemical hydrides whose purpose is to store hydrogen, especially for a specific substance - ammonia borane - as a major achievement in the field. Ammonia borane is an interesting substance because its hydrogen storage capacity reaches up to 20 percent by weight - a capacity that would be enough to propel hydrogen-fueled vehicles for a distance of about 480 km in a single tank of fuel, a value presented as a goal by the US Department of Energy .

The release of hydrogen from ammonia borane catalysts has already been demonstrated before, but its main drawback is that there are no energy efficient methods to return hydrogen to the fuel catalysts after its combustion. In other words, after the hydrogen is released from it, the ammonia borane cannot be activated in a sufficiently efficient manner.

The paper describes a simple method for regenerating ammonia borane from its dehydrogenated form using chemical reactions that occur in a single tank. This method of reactions "in a single vessel" is a significant step forward towards the practical use of hydrogen as fuel for vehicles by reducing the cost and complexity of the re-creation phase.

The re-creation of ammonia borane takes place in a sealed pressure vessel following a reaction between hydrazine and liquid ammonia at 40 degrees Celsius which is carried out, of course, outside the vehicle. The researchers envision vehicles with removable hydrogen storage tanks that contain ammonia borane that is consumed and then these tanks are sent back to the factory to be recharged.

  1. To the one pretending to be Quasimordo in Laumilch (Gildenstrasse):
    of your shoes (on second thought - no - no - please no)
    For your information, Mr. Blaomelech continued his research in the basements of the closed institution
    Another thirty years and then he was kidnapped by Alpha Centauri following an innocent mistake he made while sending a text message to 'Yapa and Hanafetz'. 24 hours later the same institution was swallowed up in a double-humped black hole.

  2. "Kazimir engine" is the most efficient engine in the world.
    It produces clean energy from vacuum only, utilizing quantum effects.

    Read about the Casimir effect.

    The first to claim to have invented such an engine was one, Casimir Blumielch. But the development failed because he had just started digging the canal named after him, then he was arrested and returned to the closed institution he escaped from - which prevented further development.

  3. A. There are constant innovations also in the solar field and in the field of batteries, there is research to increase the weightless capacity and there is also progress with bio-fuel-producing bacteria and with the distillation of bio-fuel from agricultural waste, so it is still difficult to know who will turn out to be the solution to the transportation problem - bio-fuel, hydrogen or electricity.

    B. Where did you get the antimatter from now? Creating and storing antimatter is extremely difficult if not impossible with current technology. And hot fusion is also at least another 30 years ahead according to those involved in his research.
    I haven't heard any news from Cold Fusion recently. In fact, it is not at all certain that the phenomenon exists. Regarding Andre Rossi's invention "the energy catalyst" we will wait and see..

  4. Cold fusion in combination with advanced thermoelectric materials will allow the creation of small, non-dangerous reactors, therefore this is the ultimate solution!

  5. In my opinion, hydrogen will really serve as an excellent substitute, we are so addicted to fossil fuel, in any case I still haven't understood something, if we found the most efficient substance in the universe many times more than the nuclear fission of an atomic bomb, why don't we use it? The substance I'm talking about is antimatter, one gram of which is equal to the power of an atomic bomb, so in my opinion it should be a high priority since it was one of the most efficient fuels to use in spaceships, of course there is a huge risk, but it is possible to invent new tools.

  6. Using hydrazine on a large scale carries considerable dangers, the addition of ammonia to the party only adds more dangers.

  7. There is no doubt that hydrogen is the next fuel. The fuel breakthrough described in the article is another step in the progress towards hydrogen powered machines.

    Electric machines are a solution among them and the electric machines suffer from a very low driving range and a long charging time (replacing the battery every hundred or so kilometers is not the solution).
    Reliance on electricity is also problematic. See the current shortage of electricity in Japan which forced them to shut down electric trains and pull old trains with regular fuel from storage.
    In Israel, the problem of the monopoly of managed electricity has been added where everyone will charge from home or hire companies with designated charging posts according to their free choice.
