For those looking into hydrogen generators, you might be hearing the term “dry hho” being used. If there is a dry hho there must be a wet hho right? Sort of.
The hydrogen generator technology is basically the same but with two different concepts. “Wet” hho refers to the hho generators that submerge the conductive steel plates in a container full of solution. This is the most basic form of hydrogen generators… but not as “smart” as other designs.

The wet hho systems have many different designs but use more materials. Mainly the large container. Because of the design they also have to take up more space since the plates have to be surrounded by more solution. While wet hho systems work… they are not as efficient as dry hho generators.

Dry hho generators contain the solution between the plates, separated with rubber spacers. By thinking smart, the plates and spacers become the container. A perfect example is shown in the post here where high school students build an hho generator.

This is also what makes dry hho much more efficient. For one, all of the solution is concentrated between the plates requiring less space and energy. Second, electricity is also used efficiently since it only has to travel between plates and flowing through the concentrated solution rather than flowing throughout a container. This allows more hydrogen to be produced at a much faster rate.

The clean efficiency difference make the dry version much more sustainable and economical since it produces more hydrogen. Making a wet hho system bigger requires getting a whole new container, then adding more plates and putting it back together. With dry hho if you want to make the generator bigger… all you have to do is add more plates and bolt back together. Simple as hydrogen…no wait…pie.
