The biomethane map - Research coordination for a low-cost biomethane production at small and medium scale applications

• The European Horizon 2020 project “Research Coordination for a Low-Cost Biomethane Production at Small and Medium Scale Applications”, short Record Biomap, aims to build up a knowledge transfer platform to foster the use of research outcomes which are often insufficiently exploited after the end of a research project. In the focus are technology solutions for a cost efficient biomethane production at small to medium scale, which is not yet economically competitive compared to large scale applications. Technology developments along the biomethane supply chain, from substrate pre-treatment, digestion systems up to gas upgrading processes, especially for those technologies which are yet in the first phases of their development are monitored and supported during the project duration. The present paper will give an overview of the project´s focus. The current status of collected technology profiles is presented. The promising innovative technologies “ultra-sound and hydrodynamic cavitation” for substrate pre-treatment, the “high organic loading plug-flow digestion system” and the “in-situ methane enrichment in combination with a wood ash filter” to upgrade the biogas to biomethane are explained in detail. Furthermore, the first findings on R&D needs and framework conditions are highlighted. © 2017, ETA-Florence Renewable Energies. All rights reserved.
