A new report from Germany’s environmental agency Umwelt Bundesamt addresses the question of whether residual and waste materials from biomass represent the most promising source of biogenic CO₂ for synthetic fuel production.

The outcome of a research project entitled “Criteria for the Sustainable Provision and Climate-Friendly Integration of Electricity-Based Energy Sources,” the report presents current data on global waste potential from literature sources before examining the CO₂ requirements of technical processes for the production of hydrogen derivatives. Thereafter, a qualitative sustainability assessment of the considered CO₂ point sources is provided along with a comparative analysis of global potential and demand.

The report is available only in the German language. A brief summary of the contents of the report is available here (with thanks and credit to Clean Energy Wire).
