Russian Team Develops 45% Efficient Hydrogen Production in Gas Reservoirs
Russian researchers have proposed a novel method to produce hydrogen directly in natural gas storage reservoirs. The process, which uses well-established technologies, could provide a cleaner alternative to fossil fuels. The team aims to test this method in real gas fields in the future.
The process involves injecting steam and a catalyst into a well, then adding oxygen to ignite the natural gas. The combustion produces a mixture of carbon monoxide and hydrogen, from which hydrogen can be easily extracted. The carbon dioxide formed remains in the reservoir and does not contribute to the greenhouse effect. The team has tested this method in lab reactors simulating real gas reservoir environments and achieved a hydrogen yield of up to 45%. The hydrogen yield depends on factors such as temperature and the composition of the rock in the reservoir.
Currently, approximately 80% of energy comes from fossil fuels, which release carbon dioxide when burned, contributing to climate change. Hydrogen, which emits only water vapor, could be a healthier alternative. However, its widespread use is hampered by production difficulties. The Russian team's method aims to address these challenges by using well-established technologies adapted for hydrogen production from real gas reservoirs.
Skoltech researchers have developed a method to produce hydrogen from natural gas with 45% efficiency directly in gas fields. The team plans to test their method in real gas fields in the future, potentially providing a cleaner energy source and reducing carbon dioxide emissions.
