Special Issue Information
Dear Colleagues,
This Special Issue aims to cover the latest advances within research and technological development of Power to X (PtX) technologies using biogas as the carbon source. PtX covers a group of emerging technologies that are foreseen to be vital for a flexible and robust renewable energy system as the ultimate goal of IRENA’s Renewable Energy Roadmaps. PtX enables large-scale energy storage and chemical fuel production from renewable electricity and CO2. H2 production from electrolysis is the first step in any PtX solution. However, the lack of H2 infrastructure has encouraged further development of PtX toward Power-to-Methane and Power-to-Liquid solutions, where H2 enters as a reactant along with a carbon source to produce drop-in fuels. The recent focuses on carbon capture and utilization have directed a lot of research and development within PtX technologies towards the biogas industry. Biogas consists of 40–50% CO2 and 50–60% CH4, and as a renewable fuel, it has the disadvantage of low heating value compared to natural gas. Therefore, biogas upgrading is an essential step for the development of the biomethane market in EU. Conventional biogas upgrading technologies separates CH4 from CO2 by physicochemical means and emits the CO2 into the atmosphere. PtX processes can be used as a biogas upgrading technology that to CH4 by using and valorizing the CO2 content to produce C1 or C2 products. Alternatively, the biogas can be used to generate syngas, which enables the production of higher value products, such as methanol, diesel, gasoline, etc. Yet, the development and demonstration of highly efficient PtX systems are needed to realize the potential of PtX in a global context.
Hereby, we invite you to contribute to this Special Issue with submissions of original research and critical reviews covering the development and application of both chemical and biological PtX technologies within the biogas sector.
