New Material Can Store Vast Amounts of Energy 253

ElectricSteve writes "Using super-high pressures similar to those found deep in the Earth or on a giant planet, researchers from Washington State University (WSU) have created a compact, never-before-seen material capable of storing vast amounts of energy. Described by one of the researchers as 'the most condensed form of energy storage outside of nuclear energy,' the material holds potential for creating a new class of energetic materials or fuels, an energy storage device, super-oxidizing materials for destroying chemical and biological agents, and high temperature superconductors."

          I wonder, it takes pressures to make diamonds, but the resulting material is not under pressure. I think the correct term is under stress?

          So the material might be made by using pressure, but the resulting product is not under pressure stress?

            Sorry, I'm too lazy to log in. PhD in materials science, etc.

            It's called a metastable state. It is stable because local perturbations to the structure raise the energy. If you heated diamonds up enough, they would turn to graphite because they are not the most stable state of carbon at room temperature and pressure. So, diamonds are "metastable" because they aren't truly "stable" but they also won't change on timescales that we work with due to kinetic limitations. Theoretically the diamonds will eventually become graphite, but the probability is extremely low because the thermal energy isn't high enough to let it move.

            Also, where else but the internet do random people with PhDs in materials science happen by these sorts of questions? I am very happy that I can answer your question, because thermodynamics is some of the coolest math I have ever seen.

      I suspect it is completely useless to batteries, unfortunately. To 'charge' the material you need a diamond anvil cell capable of generating a million atmospheres.

      It's not clear to me if they've even got a way of releasing the energy (is the compressed form stable?). If they have, then you're going to have to generate electricity from the mechanical expansion of a solid. The most obvious way we achieve that currently is a coiled spring, which probably won't work in this case.

      As the article says, this is basic science.

      Why do people always consider the mobile devices first??? Think big first:
      - Energy storage for renewable to allow baseline operation
      - Car fuel that only needs to be refilled monthly
      - Backup generators that don't require huge fuel tanks
      ...and finally after all other things bigger have been made to run on this you start creating the smaller versions.

      You never want to start small with new technology. Remember the problem with exploding Nokia's? I would not let a higher energy density version near my head until it's been tested in practice for years, no need to nuke my own head off...

    I used to study batteries and capacitors and the like in relation to energy storage, and one interesting comment I heard once was that storage utilising only chemical or electromagnetic methods cannot store more energy in a given lump of matter than the energy contained in its chemical bonds, otherwise the stored energy exceeds the "binding strength" of the substance, and it's liable to either leak the energy, not accept any more, or even explode.

    This is true of even things like Ultracapacitors or flywheel storage, both of which have similar issues with breakdown largely caused by limited bond strength, despite neither using chemical energy storage.

    This kind of "high pressure storage" seems to break this rule if you consider only the compressed material itself as the storage medium. If you factor in the anvil generating those pressures, then you'll find that the total system is probably quite bad at energy storage per kg of matter. There's no escaping this.

    The pressure they were using is over 100GPa (1 million atmospheres), which is notably higher than the highest tensile strength of carbon nanotubes ever measured! There's no chance in hell that a practical container could be made to contain a material at those pressures. First of all, it would have to be atomically perfect, and second, it would violently explode if it received the slightest damage!

    What the article was saying is that some of the energy imparted by the compression was stored as chemical energy. This is all fine and good, but I guarantee that if the pressure is lowered, that energy is released, and none of it can be stored at normal pressures.

      Not necessarily

      The mechanical stresses from great pressures will not cause much movement when decompressed, and so will not create an explosion, if the substance is very stiff (which is a reason liquids rather than gases are often preferred fluids for high pressure testing of piping systems)

    The substance is not stable when the pressure is released - it immediately decomposes. Carrying around the whole set-up where the typical payload (i.e. the compressed substance) is maybe 0.1% of the total weight of the apparatus is of course impractical. Also, this kind of high-pressure research is not exactly new. There are many published similar experiments where compounds undergo interesting crystal structure changes at ultra-high pressures. Nevertheless, bond strenghts limit what extra energy you can store in crystal structure variants. Xe-F bonds are definitely not among the strongest.

    -thus young Daniel Shipstone saw at once that the problem was not a shortage of energy but lay in the transporting of energy. Energy is everywhere-in sunlight, in wind, in mountain streams, in temperature gradients of all sorts wherever found, in coal, in fossil oil, in radioactive ores, in green growing things. Especially in ocean depths and in outer space energy is free for the taking in amounts lavish beyond all human comprehension.
    Those who spoke of "energy scarcity" and of "conserving energy" simply did not understand the situation. The sky was "raining soup"; what was needed was a bucket in which to carry it.
    With the encouragement of his devoted wife Muriel (nee Greentree), who went back to work to keep food on the table, young Shipstone resigned from General Atomics and became the most American of myth-heroes, the basement inventor. Seven frustrating and weary years later he had fabricated the first Shipstone by hand. He had found-What he had found was a way to pack more kilowatt-hours into a smaller space and a smaller mass than any other engineer had ever dreamed of. To call it an "improved storage battery" (as some early accounts did) is like calling an H-bomb an "improved firecracker." What he had achieved was the utter destruction of the biggest industry (aside from organized religion) of the western world.

    For what happened next I must draw from the muckraking history and from other independent sources as I just don't believe the sweetness and light of the company version. Fictionalized speech attributed to Muriel Shipstone:

    "Danny Boy, you are not going to patent the gadget. What would it get you? Seventeen years at the most. . . and no years at all in threefourths of the world. If you did patent or try to, Edison, and P. G. and E., and Standard would tie you up with injunctions and law suits and claimed infringements and I don't know what all. But you said yourself that you could put one of your gadgets in a room with the best research team G.A. has to offer and the best they could do would be to melt it down and the worst would be that they would blow themselves up. You said that. Did you mean it?"
    "Certainly. If they don't know how I insert the-"
    "Hush! I don't want to know. And walls have ears. We don't make any fancy announcements; we simply start manufacturing. Wherever power is cheapest today. Where is that?"

    The Shipstone complex is mammoth, all right, because they supply cheap power to billions of people who want cheap power and want more of it every year. But it is not a monopoly because they don't own any power; they just package it and ship it around to wherever people want it. Those billions of customers could bankrupt the Shipstone complex almost overnight by going back to their old ways-burn coal, burn wood, burn oil, burn uranium, distribute power through continent-wide stretches of copper and aluminum wires and/or long trains of coal cars and tank cars.
    But no one, so far as my terminal could dig out, wants to go back to the bad old days when the landscape was disfigured in endless ways and the very air was loaded with stinks and carcinogens and soot, and the ignorant were scared silly by nuclear power, and all power was scarce and expensive. No, nobody wants the bad old ways-even the most radical of the complainers want cheap and convenient power. . . they just want the Shipstone companies to go away and get lost.
    "The people's right to know"-the people's right to know what? Daniel Shipstone, having first armed himself with great knowledge of higher mathematics and physics, went down into his basement and patiently suffered seven lean and weary years and thereby learned an applied aspect of natural law that let him construct a Shipstone.
    Any and all of "the people" are free to do as he did-he did not even take out a patent. Natural laws are freely available to everyone equally, including flea-bitten Neanderthals crouching against the cold.
    In this case, the trouble with "the people's right to know" is that it strongly resembles the "right" of someone to be a concert pianist-but who does not want to practice.
    But I am prejudiced, not being human and never having had any rights.
