Abstract

This thesis presents the development of energy system for simulation, techno-economic optimization and design of a quad-generation energy system based on biomass gasification.

An efficient way of reducing CO2 emission from the environment is by increasing the use of biomass in the energy sector. Different biomass resources are used to generate heat and electricity, to produce gas fuel like bio-SNG (synthesis natural gas) and also to produce liquid fuels, such as ethanol, and biodiesel. Due to the fact that the trend of establishing new and modern plants for handling and processing biomass, it possible to lay a foundation for future gasification based power sector to produce flexible output such as electricity, heat, chemicals or bio-fuels by improving energy system of existing DHP(district heating plant) integrating gasification technology.

The present study investigate energy system alternative by upgrading existing district heating plant. It provides a generic modeling framework to design flexible energy system in near future. These frameworks address the three main issues arising in the planning and designing of energy system: a) socio impact at both planning and proses design level; b) technical impact to select different technologies and types of equipment from available options; and c) economic concern to validate new technology with existing one. To achieve the above issues a life cycle assessment (LCA) analysis and techno-economic analysis of quad-generation system have also included in this study.

The overall aim of this work is to provide a complete assessment of the technical potential of biomass gasification for local heat and power supply in Denmark and replace of natural gas for the production. This study also finds and defines the future areas of research in the gasification technology in Denmark within the development of green syngas for different sector including transportation sector. Computational models of whole system component for steady-state operation were developed and also system concept and key performance parameters were identified.

The main contribution of this project to ascertain new and flexible technologies that could contribute for local heat demand and supply, national gas grid connection, and short term power marketing perspective in an economic evaluation.
