The sustainability of fuels and power generation with cleaner production of exhaust gases is considered one of the most important goals that the world seeks. The electrolysis process of water produces oxy-hydrogen gas (HHO) that can be used as an energy source to solve the shortage problem of fossil fuel and reduces the environmental pollution. The availability of water guarantees the sustainability. In this study, HHO dry cell generator was designed, fabricated and tested experimentally to investigate its performance. The hybrid internal combustion engines using HHO gas is considered one of the most important studied applications. The engine performance and gas emission are investigated for two different engines; 150CC with carburetor and 1300CC with Electronic Control Unit (ECU). The results recorded the consumption of the fuel was reduced by 14.8% for 150CC engine and 16.3% for 1300CC engine. HHO gas reduced the emitted gases (clean production) by 33% and 24.5% reduction in CO and 27.4% and 21% reduction in HC for 150CC and 1300CC engines respectively. A new application of HHO gas is to use it in water desalination. A hybrid solar still using oxy-hydrogen is investigated and its productivity of distilled water was examined. The proposed new system of water desalination can work throughout the day and it has a daily accumulative distilled water productivity 19.1 l/m2, i.e. 4.8 times higher than the conventional system, but its efficiency is lower than the conventional system. HHO gas has different domestic and industrial studied applications with high efficiency such as cooking, welding and cutting. So, HHO gas can work individually and hybrid as an efficient fuel.
