Hydrogen Generator: Economic Feasibility

Hello, there are questions about the hydrogen generator. Namely, economic feasibility. The efficiency of this heating system in real conditions is interesting. how much electricity is needed to get 1kW of heat? And another question about the manufacture of this installation: how much money do you need for manufacturing? Well, the service life of the installation.

Expert Answer

Good afternoon, Cyril. According to reports, a correctly assembled and tuned hydrogen generator consumes a current of 9A from a 220 V network to produce 24 liters of a hydrogen-oxygen mixture (Brown gas) per minute. The actual power spent is about 2 kW. As for the calorific value of the gas composition, when burning 1 liter of Brown gas in terms of power, 2 W is generated.

By simple conversion we get 24 × 60 × 2 = 2.88 kW at a cost of 9 × 220 = 1.98 kW, that is, the calculated efficiency of the installation is 145%.

The cost of manufacturing a hydrogen generator completely depends on the size and number of cells, as well as on whether you can make the electrical part yourself. If you don’t have skills in soldering electronic circuits, then you can buy a pulse generator (its cost can be found on specialized sites). By the way, ready-made generators are sold on EBAY or Aliexpress - there you can see the price of the device of the power you are interested in.

The service life depends entirely on the quality of the stainless steel plates (it is recommended to use the brand indicated in article) and the purity of the electrolyte. It must be said that, subject to the technology, the generator's durability is thousands of hours. And the last: now using the device for heating is irrational, but for cooking or saving fuel in a car, such a device will be indispensable.
