Sustainable power generation by using fuels and energy conversion technologies that emit little to no pollution is one of the critical objectives of the modern world. Given their improved ability to mix with air, increased combustion efficiency, ease of transportation, and less pollutant generation, gaseous fuels are employed increasingly frequently in internal combustion (IC) engines in this setting. As alternative gaseous fuels for IC engines, liquefied petroleum gas, compressed natural gas (CNG), hydrogen, and biogas are seen as being widely accessible. However, the world is still looking for other alternative gaseous fuels. Many academics worldwide have been looking at the prospect of employing oxyhydrogen (HHO), commonly known as Brown’s gas, for heat and power applications in recent years. As a result, a thorough analysis of the production of HHO using various generators and its application in heating and electrical applications has been conducted. A comprehensive review of published results is also reported in this study to highlight the commercial application limitations. |
