Brussels, 5th of March, 2025. The Biomethane Industrial Partnership publishes the report “Advances in CO₂ valorisation and integrated hydrogen-biomethane production.”
The report, prepared by Task Force 5.3, provides a comprehensive analysis of two key areas in the field of biomethane production: the enhancement of methanation technologies for the valorisation of biogenic CO2 and the development of technologies for the integrated production of hydrogen and biomethane.
The report’s dual scope allows for an exploration of these areas. Firstly, it assesses improved methanation technologies that enable the recycling and valorisation of biogenic CO2. This includes the examination of catalyst development, process optimisation, and integration with renewable energy sources, all aimed at maximising the conversion of CO2 into methane.
The report then analyses technologies that enable the integrated production of hydrogen and biomethane. It delves into the potential of the solid fraction of produced digestate for hydrogen production and the catalytic/thermochemical conversion of methane to hydrogen once biomethane has been produced.
The report highlights the ongoing research in developing more active, stable and cost-effective catalysts and optimising reaction conditions. While the potential for creating a water system that does not increase freshwater demand is recognised, particularly in regions with scarce water resources, this aspect should be assessed in future reports.
In conclusion, this report presents an examination of the current landscape of methanation and integrated hydrogen-biomethane production technologies.
