HyPower said that its H2 Reactor is an electrolyzer that uses electrolysis to create hydrogen and oxygen gases from water. It can be used on-board for injection into any internal combustion engine, according to the firm.

The firm said that interested parties range from fleet operators to single vehicle owners intent in saving on their fuel usage. The demand for the products is reportedly more than the supply, even with an increase of 10% in their retail prices.

Douglas Bender, president of HyPower Fuel, said: We have been unable to accommodate the calls of demand for our products. We are now in the process of establishing a listing of backordered units which, in all likelihood, will be approximately 1,000 units.
