Researchers from Skoltech have developed a groundbreaking method to produce hydrogen from natural gas fields with 45% efficiency. By injecting steam, a catalyst, and oxygen into gas wells, hydrogen is extracted from the combustion of natural gas components like carbon monoxide. This process, supported by the Russian Science Foundation, aims to facilitate the transition from fossil fuels to clean hydrogen energy. Natural gas is known to emit carbon dioxide, making it an environmental concern, while hydrogen offers a cleaner alternative as it only produces water vapor when consumed. The team proposed a multi-step approach involving steam injection, catalyst-assisted combustion, and membrane extraction to separate hydrogen from other gases. Lab experiments using methane and different rock compositions demonstrated successful hydrogen production efficiencies of up to 55%. The study leader, Elena Mukhina, highlights the potential of this technique for real gas field applications, showcasing its ability to convert hydrocarbons into green fuels efficiently.
