Hydrogen Introduction

Save 20% On Fuel. Easy Make DIY Hydrogen Generator.

Easy to make DIY Hydrogen Generator

I made my first Hydrogen generator on the kitchen table without any special tools and it was so simple even I was amazed.

I then spent much of my time watching You-tube videos on the many different ways to construct Hydrogen Generators and after some time I filtered it all down to the simplest parts and build a small Oxygen-Hydrogen generator myself with only kitchen items and no special tools.

It was so simple and worked so well that I decided to make second version and attach it to my small town bike and amazingly the top speed increased and fuel economy improve by nearly 20%.

HHO generator

It’s a very simple setup and I hope that this article and the videos will help you to make one too.

If you are sceptical about this process and its possibilities you can see some of the technical research details in the link below…

‘HHO generator is an efficient approach that [is] used to increase the fuel efficiency in a combustion engine by increasing the energy produced per mole of fuel during the ignition process. As a result the amount of unburned fuel in a combustion engine was reduced’.  An Approach to Increase Fuel Efficiency in Spark-Ignition Engines  (PDF Download).

Why do we want Hydrogen?


Hydrogen is highly flammable and ignites very easily. It has the highest rating on the ‘flammability scale’ and will burn easily in very small amounts.

This means that it is much more flammable than petrol vapour and when added to the air intake of an engine it will increase the fuel burn efficiency and overall efficiency of the engine’s combustion process.

Hydrogen power

Even the addition of a small amount of 4% and above of Hydrogen will:

  • Increase power output;
  • Reduce fuel consumption;
  • Reduce carbon emissions.

Some of the other good news about Hydrogen is that it is colourless, odourless, tasteless, non-toxic, non-poisonous and non-corrosive. Also, the energy required to initiate combustion is much lower than that required for petrol vapour. Perfect!

But, take care because it is HIGHLY flammable!

What is Hydrogen and how do we get it?

Hydrogen is an integral part of water. It is the ‘H’ in H2O. Getting Hydrogen out of water is a remarkably simple process.

Hydrogen Anode CathodeYou can simply place two metal spoons into a glass of water. Attach one spoon to the negative of a battery and one spoon to the positive and bubbles will appear on the spoons. These bubbles are Hydrogen and Oxygen which is being released from the water by a process called electrolysis. You can see an actual spoon in operation HERE.

That is it, your first Oxy-Hydrogen generator.

It is that simple!

This is the first Clever Video showing the construction of a very easy to make Oxy-Hydrogen generator made on the kitchen table without the use of any special tools.


HydrogeWhy do I need to use Stainless Steel?

Stainless steel is less likely to corrode during the electrolysis process. Keeping the generator clean and free from impurities is an important part of maintaining its efficiency.

Many kitchen Items are made of stainless steel. For my generator, I used some cheap stainless steel rice bowls as they were easily available and fitted into the container I had.

What is the ‘Bubbler’ for?

Hydrogen bubblerThe ‘bubbler’ is simply a one-way valve and is literally a small bottle with some water in it. The gas produced in the generator passes out of the exit pipe and goes into base of the ‘bubbler’. The gas rises to the top of the container through the water as bubbles. Hence its name.

The gas rises to the surface and then continues on its way out of the top of the container into the engine. If the hydrogen is ignited by a back-fire in the engine the flame will travel back down the feed pipe but will not be able to pass back through the water and get into the main generator. It basically acts as a one-way valve.

There are plenty of simple one-way valves (check-valves) and purpose-built flash-back arrestors that are small and cheap and can be neatly fitted into the supply pipe between the engine and the generator but, like many builders, I like to see the bubbles so that I can gauge the rate of production of the generator. When I am confident of the output the ‘bubbler’ will be replaced with a small inline unit.

Additional Notes for Builders:

Why are Neutral Plates Used?

Hydrogen neutral platesIf you use only a negative and positive plate the output will be high but the current flow will also be very high. This will cause your battery load to be high and also cause heat build-up which will further increase current flow.

Ideally, the voltage should be below 2v (1.6 ideal) across the plates. This will keep the HO production constant with little heat increase and unnecessary battery drain.

To reduce the overall voltage in the system neutral plates are placed between the Positive and Negative plates. These plates are not connected and each plate reduces the overall voltage across the system by roughly 2v per neutral plate.

This means that for a 12v system 5 neutral plates will reduce the overall voltage to around 2v.

What is Baking Soda Used For?

Baking soda is added to the water to improve its conductivity. Other compounds can be used but I found this to be the easiest to buy (from the local supermarket) and safest to use in the kitchen.

The amount of baking soda added to the water in the generator will affect the ease at which the electrons can pass through the water. As more baking soda is added to the water the more conductive it becomes and the current flow between the plates increases.

As a rough guide, I used 2 dessert spoons of baking soda mixed with a litre of water.

It is a good idea to use an ammeter to see how much current the system is drawing to make sure that you do not overload the battery/charging system.

If you do not have an ammeter (which you should have as good practice anyway), you can fit a car fuse to the positive supply from the battery which will disconnect the circuit if the current flow is excessive. You can use a standard 10Amp, 15Amp, or 20Amp car fuse to protect your system. Having said that, small units should not normally cause any problems if neutral plates are used to reduce the overall voltage in the generator.

Watch the second video  where I fit an improved version of the generator built in part 1 to my bike and run it.
