Pilot-Scale Sustainable Oxyhydrogen Production: A Pathway to Clean Hydrogen and Green Energy Solutions

This study explores the development and performance evaluation of a pilot-scale sustainable oxyhydrogen production system, aiming to address the urgent need for clean and renewable energy solutions in the Philippines. The system utilizes microhydropower as a renewable source to drive electrolysis for hydrogen and oxygen generation. A 220-liter elevated tank supplies water to a Pelton turbine, which powers a permanent magnet generator connected to a charge controller and battery bank. The stored energy runs a 17-plate wet cell electrolyzer, producing consistent hydrogen output. The study assessed temperature, flow rate, gas output, and electrical parameters under various test conditions. Results show a stable 1 Liter per Minute (LPM) hydrogen production rate at 12V and 5A, with higher Potassium Hydroxide (KOH) concentrations enhancing output. This research validates the feasibility of oxyhydrogen systems powered by off-grid renewable sources, with implications for energy independence, environmental sustainability, and rural electrification. The findings support the national goals of integrating hydrogen into the energy mix, providing a clean and scalable solution suitable for communities with abundant water and renewable energy resources.
