  • HODCELL - Hydrogen (H2) bench test (near disaster)

    I guess I was tired last night..

    I did an experiment on the bench ... and forgot to turn OFF the 120V BURNER !!!

    The TEMP went up to 260 degrees !

    It belched out steam and the HODCELL BELCHED OUT the CC FOAM / WATER from the SS Canister into the bubbler !

    I quickly opened the VENT valve to let the pressure escape.

    I turned off the burner... and then backed away 20 feet ... awaiting an explosion ...

    Luckily .. nothing blew apart.

    I then slowly opened the nuts on top of the stainless steel canister ... and let the steam pressure ESCAPE OUT of the HODCELL.

    (Good news, is the HODCELL is AIR TIGHT and able to HOLD SOME STEAM PRESSURE).

    Then I was able to clean up the mess... and RESET the HODCELL on the bench for a 2nd experiment.

    Lesson learned: TURN OFF THE HEAT - at 150 Degrees F !!!

      Why are you making Hydrogen?

      As stated in science books and Wikipedia:

      Hydrogen is not an energy resource, except in the hypothetical context of commercial nuclear fusion power plants using deuterium or tritium, a technology presently far from development.

      The Sun's energy comes from nuclear fusion of hydrogen, but this process is difficult to achieve controllably on Earth. Elemental hydrogen from solar, biological, or electrical sources require more energy to make it than is obtained by burning it, so in these cases hydrogen functions as an energy carrier, like a battery. Hydrogen may be obtained from fossil sources (such as methane), but these sources are unsustainable.

      The energy density per unit volume of both liquid hydrogen and compressed hydrogen gas at any practicable pressure is significantly less than that of traditional fuel sources, although the energy density per unit fuel mass is higher. Nevertheless, elemental hydrogen has been widely discussed in the context of energy, as a possible future carrier of energy on an economy-wide scale. For example, CO2 sequestration followed by carbon capture and storage could be conducted at the point of H2 production from fossil fuels. Hydrogen used in transportation would burn relatively cleanly, with some NOx emissions, but without carbon emissions.

      However, the infrastructure costs associated with full conversion to a hydrogen economy would be substantial. Fuel cells can convert hydrogen and oxygen directly to electricity more efficiently than internal combustion engines.

      Hydrogen is a two-edge sword. It is abundant (usually attached to another element such as Water H2O or Aluminum AL). And, with a little chemistry, the H atoms can be freed where they quickly combine with each other producing Hydrogen Gas (H2).

      On the other hand, Hydrogen loves to BIND with almost anything. So, it is very difficult to contain and can make some metals brittle.

      Here on Earth with our standard pressure and temperature, H2 wants to remain a free-roaming gas. But, when we do harness the Hydrogen element, it can be consumed to yield power in the form of mechanical, chemical, heat, and electrical processes.

      So... Hydrogen costs energy to free-up the H2 from abundant carrier molecules. And, then costs more energy to store by compression pumps into tanks.

      One of the most efficient methods to release pure Hydrogen (H2) is to use powdered aluminum. The HODCELL follows Dr. Philips research in using powdered aluminum (30 microns) with a carbon catalyst (CC) in a bath of water (H2O). By heating the solution up to about 180 degrees F, a massive amount of Hydrogen (H2) will be released from the Aluminum.

      If the H2 is consumed on-demand (Hydrogen On Demand = HOD), then there is no need to store the gas. This opens an opportunity to easily produce Hydrogen and use it on-demand with a very small investment of Aluminum and Heat to start the exothermic chemical reaction. The reaction will continue as it generates its own heat until the Hydrogen has been released from the surface area of the Aluminum powder.
