The best HHO Electrolyte (catalyst) for my HHO Gas Generator?

Use an electrolyte that suits the best to you HHO Gas generator design. The distance between the electrode plates does really matter.

A - For electrodes with little distance between the plates you could use: tap water or distilled- rain- or demy water with a very little of any of the catalysts mentioned below.

B - For electrodes with more space between the plates tap water won't work. So use distilled- rain- or demy water with a little of the catalysts mentioned below.

C - For electrodes with a lot of space between the plates tap water won’t work. Use distilled- rain- or demy water with a one of the catalysts mentioned below.

1 - Tap Water - H2O (containing minerals, salts etc.)


  • Available everywhere
  • Cheap
  • Safe


  • Water might turn brown with smudge on the electrodes
  • Water that contains chlorine should not be used

The best water for a HHO generator we found to be: Bottled Mineral Water

Distilled water is not recommended (any longer...)

2 - White Vinegar - acetic acid - H3C-COOH


  • Stainless electrodes stay clean
  • Available everywhere
  • Cheap
  • Safe


  • Smells
  • water will become dark

Available at your local grocery store.

A good mix for medium distance electrodes: 100% vinegar with (only if necessary) some baking soda. (If do so be carefull, because the reaction will produce co2 and some other gasses!)

2 - Baking Soda ( Natriumbicarbonate ) NaHCO3


  • Available everywhere
  • Cheap


  • Electrodes and water might turn brown
  • Produces Co2 (30%) and Co (4%).
  • For this reason not recommended

Pure Baking Soda might leave a brown tinted residu.

3 - Sodium Hydroxide also called Lye = NaOH


  • Electrodes stay clean
  • Cheap
  • 95 - 100% pure HHO (oxygen hydrogen) Gas production with right generator design
  • Available in the Grocery store


  • Limited dangerous to work with
  • Too much heat causes corrosion

Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution. It is deliquescent and readily absorbs carbon dioxide from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. Use with distilled water.

Not recommended

4 - KOH

Also called pottassium hydroxide.


  • Electrodes stay clean
  • 95 - 100% pure HHO gas production along with the right generator design
  • strong and pure electrolyte


  • Not available everywhere
  • dangerous to work with

Recommended as very good electrolyte (recommended by Honda in 2001)

5 - K2CO3

Pottassium Carbonate.


  • Non aggressive
  • Reasonable / good HHO gas production depending on HHO cell design
  • Cheap
  • Safe to work with


  • It is possible (sometimes necessary) to mix it with a little Koh to draw more amps.

Winter Electrolyte:

Developed by mr. M. Moldoveanu

Water+Ethyl Glycol+KOH will provide the benefit the technical of low freezing point but high boiling point at the same time.

General information to get the best results:

Use destilled water or bottled mineral water only.

For most cars between 10 - 30 amps should give good results. Prevent to add too much watervapour into Diesel engines. Too much watervapour could delay the ignition of the fuel mixture which might cause using more fuel.

Do not try to get too much HHO gas volume out of your generator by using a lot of amps etc. It will certainly become overheated and your electrodes could be damaged. Or you will generate steam. It is better to a larger number of (small) generators to get the gas volume you need. Or use a HHO generator with a pump system. Advantages: The generators will stay cool / warm, uses less power, is safer and will last longer(!)

Your optimum draw should be several amps less when cold so keep adding little by little. until you get to your optimum amp draw. (sometimes it will double)

A few Golden Basic HHO rules in a nut shelf:

  • Distance between plates > 3mm
  • Electrodes should be made of 316 L stainless steel
  • Use distilled water and KOH for electrolyte
  • Don't exceed 1,8 volts between the plates
  • Keep the HHO Cell temperature under 50 Celsius always
  • take care of safety!

Fuel Savings Tips

Millions of dollars worth of gasoline is wasted every day by motorists, because simple and inexpensive vehicle maintenance is neglected.

Fuel Savings Maintenance Tips

  • Check vehicle gas caps - About 17 percent of the vehicles on the roads have gas caps that are either damaged, loose or are missing altogether, causing 147 million gallons of gas to vaporize every year.
  • Make sure tires are properly inflated(do not over pressure the recommended pressure use the recommended pressure as in car manual - When tires aren't inflated properly, it's like driving with the parking brake on and can cost a mile or two per gallon.
  • Replace spark plugs regularly (Recommended every 5000km~8000km as max)- A vehicle can have either four, six or eight spark plugs, which fire as many as 3 million times every 1,000 miles. That results in a lot of heat and electrical and chemical erosion. A dirty spark plug plus causes misfiring, which wastes fuel. Spark plugs need to be replaced regularly.
  • Replace dirty air filters - An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a "rich" mixture - too much gas being burned for the amount of air, which wastes gas and causes the engine to lose power. Replacing a clogged air filter can improve gas mileage by as much as 10 percent.

Fuel Saving Driving Tips

  • Don't be an aggressive driver - Aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets.
  • Avoid excessive idling - Sitting idle gets zero miles per gallon. Letting the vehicle warm up for one to two minutes is sufficient.
  • Observe the speed limit - Gas mileage decreases rapidly at speeds above 60 mph. Each mile driven over 60 will result in an additional 10 to 20 percents oil loss per gallon. To maintain a constant speed on the highway, cruise control is recommended.
