Yorkshire Green Fuels Ltd: Hydrogen Generation by Electrolysis

The hydrogen generator kit from Yorkshire Green Fuels Ltd is a simple and safe way to generate hydrogen for use in your car engine. Its electrolytic operation using can be summarised as follows:

• The main part of the kit is an electrolytic chamber containing distilled water with bi-carbonate of soda dissolved in solution.
• Electric current from the car battery passes through the electrolytic chamber between the supplied metal electrodes.
• The electric current causes an electrochemical reaction which converts bicarbonate of soda into sodium carbonate (a harmless substance, in solution) and hydrogen gas.
• As this is a steady process, hydrogen is released at a constant rate and there will be no sudden pressure build up.
• The hydrogen passes along the exit hose and through the safety valve.
• This hose merges with the air intake system for the engine. We recommend that the junction is installed by a competent person (see installation instructions below).
• In the combustion cylinders of the engine, hydrogen takes the place of up to 25% of the fuel vapour normally present.
• Hydrogen is burnt alongside the traditional carbon fuel, its emission product is pure water in the form of steam.
• The combustion of hydrogen is environmentally neutral, so the overall effect is to reduce your engine emissions by a proportion up to 25%.
• The cost of generating the hydrogen is minimal.
• The kit is simpler and safer to operate when wired to the car battery through the ignition circuit. Hydrogen will then be generated only when the ignition switch is turned on.

Fitting Instructions for Electrolytic Hydrogen Generation

ONLY USE BICARBONATE OF SODA IN THIS MODE Set Generator securely in engine away from all heat sources. Before fitting lid fill container about 3/4 full with distilled water. Add one tablespoon of bicarbonate of soda and stir until dissolved. Fit lid to generator and attach wires, live to red terminal and earth to black terminal, the in line fuse is fitted in the live wire near the power source which needs to be via the ignition to ensure the generator is switched off when not in use. Attach hose to generator then connect to engine by drilling a small hole into the air intake system after the air filter and close to the engine but before any turbo charger, feed the hose in and seal with silicone. Form a loop in the hose below the generator cap and the input to the engine, into this loop pour a couple of inches of water to form a water trap in case of a flashback (There is also a check valve included in the kit) A maximum of three tablespoons of bicarbonate of soda can be used with this generator but care must be taken to avoid overheating so start with one tablespoon. Check the temperature of the generator by touching the outside casing which should be hot but not so hot that you can't hold your hand on it, if it is too hot reduce the amount of bi carbonate of soda and to increase the heat add bi carbonate of soda one half tablespoon at a time. The amount of hydrogen required is between 0.25 and 0.5 litres per litre of engine therefore a three litre car would use one litre of hydrogen per minute. Electrolysis using this kit can produce up to 2 litres of hydrogen per minute per minute. WARNING! The electrolyte produced by the Hydrogen Generator contains traces of Chromium 6 and according to Environmental Services the amount produced is so small that it would pose no threat to health or environment, however it would be prudent to dispose of the electrolyte responsibly and avoid contact with skin.
