Metal Fuels – One of the Most Promising Fuels for the Future?

  1. A major use of fossil fuels (FF) is to power vehicles. Liquid FF have the advantage of high energy density, easy storage, and easy transport to the engine. There are reasons that we don’t use coal dust in cars and trucks. The reasons are the same for powdered metals. Powders are not as easy to transport, store, and move to the engine. However, there is a much more important consideration. What to do with the iron oxide (rust) that results from the ‘combustion?’ You can’t just dump it on the highways. We’d be plowing our way through orange ‘snow.’ It you capture it and keep it onboard, it increases the weight of the vehicle and reduces the efficiency of the fuel. What do you do with it when you get home? You can’t dump it in your yard. In fact, it you live in a humid climate, it may almost be impossible to get it out of the storage compartment. Even if you do, then what do you do with it? It becomes yet another waste product to handle. If there is a loss of the iron fuel or iron oxide waste-product to the environment, it could become a serious hazard to breathing, and even to plants, depending on the particle size. Burning iron may find niche applications, but I don’t see it replacing conventional liquid fuels.

  2. I assume they are considering this for use in static applications rather than for transport where the weight would be prohibitive for the performance and competing with electric vehicles almost impossible.

    If this can be accomplished efficiently at scale then it could be a useful means of energy storage for electricity generation, but right now that seems very far off.

    During temperature changes, water condenses in my car’s gas tank. I wonder what real world conditions will do for this fuel.

  4. “which requires a solid understanding of their combustion physics” 😉

    • Someone who apparently has never witnessed magnesium burning in a basic chemistry class shouldn’t try to read journals…
