Methane Production via Sabatier Reaction Using Hydrogen from Rainwater Electrolysis and Captured Carbon Dioxide
Year: 2025
Type: preprint
Abstract: Rainwater accumulation during heavy rainfall and urban waterlogging presents both environmental challenges and resource opportunities. This study investigates the production of methane gas by utilizing hydrogen derived from rainwater electrolysis and carbon dioxide captured from human breath. Rainwater was purified by vaporization and condensation before electrolysis. Hydrogen gas was collected and subsequently reacted with carbon dioxide under heat (300–400 °C) in the presence of a nickel catalyst, following the Sabatier reaction. Methane gas was successfully produced, and water formed as a side product. The study demonstrates the potential of using rainwater as a renewable hydrogen source and readily available carbon dioxide for small-scale methane synthesis, providing a proof-of-concept for sustainable energy applications.
