Declining viability of biogas production followed by a stagnation of dissemination of biogas plants calls for new repowering measures as increased amounts of storable energy sources from biomass are required for providing a smooth integration of fluctuating renewable energy sources in the electricity market in future.The implementation of biogas microgrid concepts as a repowering measure allows for a combination of organizational and technological efficiency increase as a result of decoupling of biogas production from utilization.The first objective of the present work is the development of a tool for techno-economic assessment of biogas microgrid configurations .The second objective of the work is the application of the tool for assessing the concepts’ potential for efficiency increase based on its unique features: gas storage and gas transport. These features were assessed for the two most promising biogas utilization pathways being bio-methane production and flexible electricity generation from biogas.The tool is an Excel© based model where biogas microgrid relevant processes such as drying, desulphurization, compression but also the upward and downward processes of biogas production such as biomass transport and electricity generation/methanization are described with mathematical-physical equations. Based on the latter, calculations related to energetic performance and storage capacity are preformed. The economic assessment is based on the annuity method .The fixed costs of the biogas microgrid components are expressed as functions of scale (capacity).The techno-economic calculations are preformed in three modules. The modularity of the tool allows for flexible adjustment of selected biogas microgrid configurations to various local conditions. Consequently the configuration can vary in following parameters: (a) length, (b) substrate type, (c) number and (d) capacity of connected biogas plants, (e) grid structure and (f) biogas utilization pathway.

The importance of renewable fuel production has become significant in terms of supplying energy carriers for the transportation sector and storing electricity over ows from intermittent sources. The purpose of this book is to address, model and assess economics of methanol production schemes from a biogas origin. It is envisioned that the establishment of this biomass-to-liquid process will enhance biogas production. The enhancement is based on creating an alternative utilization method of biogas than combustion for CHP. The benefits from the establishment are projected to be a reduction in GHG-emissions from livestock waste and a biofuel contributor to renewable liquid energy carriers. A farm and a central large scale scenario are investigated. The production scheme assessed is based on biogas from degassed bio-waste and a biogas reforming technology. A Solid Oxide Electrolysis Cell is adapted to the process schemes, partly to improve composition of reactants for methanol synthesis and to act as a peak shaving mechanism for the electricity overflows. A heat integration and economic assessment is established and subjected to a cost-optimization estimating methanol production prices.

Today's bioenergy systems are frequently characterised by limited conversion efficiency and dependencies on few species of energy crops leading to low biodiversityin plant production. With the aim to improve the ecological performance of biomass production and processing and to convert a wider spectrum of biomass resources, the integrated generation of solid fuel and biogas from biomass (IFBB) was developed. Its core element is the mechanical separation of the wet conserved biomass into a solid fuel for combustion and a liquid for anaerobic digestion with subsequent production of heat and electricity from the biogas. This study investigated biological and chemical parameters of the IFBB process. Furthermore, life cycle assessment was conducted to evaluate the overall energy efficiency as well as saving potentials of fossil primary energy and emissions of greenhouse gases of the IFBB process along the entire process chain.

This book derives an explicit analytical pattern (or framework) that permits the examination and optimization of biogas production systems. It provides a concise overview of the current status of biogas and biogas coupled agricultural systems in China, and introduces evaluation methods for energy efficiency, environmental emissions, economic performance and sustainability assessment approaches. Based on empirical studies, it also explores future options for the system development by focusing on emissions mitigation, biogas energy efficiency and system sustainability. Systematic methods of life cycle assessment and thermodynamic analysis may provide new angles for biogas system evaluation. The system discussed is not only a biogas producer, but also a biogas-linked ecological agricultural system, which has the potential to broaden the applicable scopes of renewable energy and eco-agricultural management. The comprehensive, in-depth knowledge and experience presented provide new analytical approaches for researchers in relevant fields and shed light on the construction and operation of emerging anaerobic digestion and biogas industries. This book is a valuable resource for researchers focusing on biogas system modeling, project managers and policymakers.
