  • NIckel Iron Back in the News Again

    This technology just will not go away.

    The issue I see is that storing hydrogen usually requires compressing it. Many of the electrolyzers and membrane units can make low pressure hydrogen but their efficiency drops as the pressure increases.

    I haven't looked at how they are classified in the new 2020 NEC.

      Everything old is new again ! Interesting. The main issue is constructing the cells to have individual vents for H and O2, and if you let fluid levels drop enough that they start to mix - you go boom

        Admittedly, I've been doing some investigation (youtube) into hydrogen harvesting/storage and decided against it.

        Hydrogen needs to be pure and at 100 PSI is a relatively dangerous activity to do from home.
        Any air mixed with the hydrogen during compression and you could trigger an exothermic reaction, aka boom.

        And besides, I don't want to be poisoning the electrolyte anyway from needing to replenish it with water, my closed loop recombiner vent plugs are sufficient.
