“…The HHO gas, also known as Brown's Gas, is a gas that results from water electrolysis. Water electrolysis is the process of breaking down water molecules (H2O) into hydrogen (H2) and oxygen (O2) using energy from an electric current passing through the water [26][27][28]. Direct production of HHO gas is straightforward using the existing power in the vehicle (i.e., battery) [29].…”

The excessive use of fossil fuels and the resultant dramatic increase in pollution levels have highlighted the need for a new sustainable and environmentally friendly fuel. Hence, it is necessary to research alternatives to reduce the use of fossil fuels and the emission of greenhouse gases. Utilising oxyhydrogen (HHO) gas has been proven to achieve high engine power output and efficiency with low emissions for spark-ignited internal combustion engines. HHO gas is generated from the electrolysis of water. This paper reviews the recent research findings related to the influencing factors on the production of HHO gas using alkaline water electrolysis involving electrolyte properties, electrolyte concentration, the distance between electrolytes, and the effects of HHO gas on the engine performance and gas emissions. Using an HHO gas blend in a diesel/gasoline engine could be a viable option for lowering GHG emissions and increasing engine efficiency.

“…Calculated theoretical specific energies and specific energies in real systems have reached 1,090 Wh/kg and 200 Wh/kg, respectively, which both are far less than the value for pure aluminum. By using a mixing system and a complex electrolyte supply, such batteries are utilized in the marine sector [106]. Because the Al electrode inherently generates hydrogen, it is required to design batteries with a different design in which metallic Al is not used [107].…”

Summary In this research, a novel integrated system for renewable hydrogen production, power, and hot water from solar thermal energy has been developed and precisely evaluated in terms of thermodynamics. The developed structure is comprised of a four‐step Cu‐Cl thermochemical cycle, and an organic Rankine cycle to generate electricity. The required heat is supplied by a concentrated solar power plant and thermal energy storage based on latent heat. Also, a high‐temperature heat pump is employed to improve the thermal grade of working fluid and provide each unit with sufficient heat. System dynamics simulation has been performed using weather and irradiation input data of Tehran, Iran. The integrated structure has the capability to produce 21.75 kg/h of hydrogen, 563.6 kW of electricity, and 393.3 m3/h of hot water at 70°C. The energy efficiency of the system reaches more than 80% based on higher heating value and the solar‐to‐fuel efficiency has a value of 25.8%. Moreover, an exergy analysis has been executed to determine the fundamental operating parameters of each component and the whole structure. The total exergy efficiency of the integrated structure is 34.23%, and the prime cost of the product is found to be 5.795 USD/kg H2.
