Abstract:

Methane-producing Bioelectrochemical systems (BESs) is a promising technology converting renewable electricity into the form of storable methane. The objective of this thesis is to achieve efficient methane production in methane-producing BESs and investigate its applicability in full-scale powerto- gas projects. We focus on improving the biocathode performance by exploring suitable cathode materials and operational conditions, e.g. decreasing biocathode start-up time by using heat-treated stainless steel felt (Chapter 2), achieving high-rate methane production by using a granular activated carbon (Chapter 3). We also investigated the effect of intermittent electricity supply on performance of carbon-based biocathodes in methane-producing BESs (Chapter 4). We showed that integrating methane-producing BES into anaerobic digestion could be an attractive strategy to enhance the performance of anaerobic digestion in cold area (Chapter 5). Based on the results of this thesis, we evaluated the possible main issues by performing a techno-economic analysis of a full-scale methane-producing BESs (Chapter 6).
