Several decarbonised polygeneration systems exploiting carbon capture and storage (CCS) or CO2 reuse technologies for the conversion of primary resources into clean fuels, chemicals, electricity and heat are systematically analysed for techno-economic feasibility. A process simulation, energy integration and economic analysis based approach has been employed to arrive at a representative set of...

The forecasted shortage of fossil fuels and the ever-increasing effect of greenhouse gas (GHG) emissions on global warming and environmental stability are two international problems with major technical, economic and political implications in the 21st century. Therefore, it is urgent to restructure present energy production and utilization systems in order to ensure that fossil fuels are used w...

Polygeneration systems offer the possibility of efficient, low-carbon production of different product streams from a single facility. Such systems take advantage of opportunities for integrating processes to achieve effective recovery of waste energy and material streams. Mathematical programming methods have proven to be valuable for the optimal synthesis of such polygeneration systems. Howeve...

In this paper the first results of a new method for the configuration of district energy systems are presented. District energy systems are believed to help decreasing the CO2-emissions due to energy services (heating, cooling, electricity and hot water), by implementing polygeneration energy conversion technologies. However, because polygeneration technologies are complex, it is meaningful to ...

Polygeneration of hydrogen, heat, and power has been shown to improve overall plant efficiency by creating more products and introducing synergy which improve fuel cell performance (Figure 1). The integration of an absorption chiller with a high temperature fuel cell for polygeneration of combined cooling, heating, hydrogen, and power is studied. Steady-state and dynamic computer models are uti...

During the last years, special attention has been paid to renewable polygeneration technologies, able of simultaneously producing thermal, cooling, electrical energy and desalinated water from seawater. This paper focuses on an innovative polygeneration system driven by renewable energy sources, including the following technologies: hybrid photovoltaic/thermal collectors, concentrating paraboli...

In this study, cooperation between Stockholm’s transport and district heating sectors is analysed. The cooperation concerns the integration of biofuel polygeneration production. A MODEST optimisation model framework is used, assuming various energy market and transport sector scenarios for the year 2030. The scenarios with biofuel production and increased biofuel use in the region are compared ...

Polygeneration is the process of combining multiple utility outputs with one or more input(s) in a single integrated unit. The integration is towards a higher energy efficiency as well as environment friendliness. Fossil fuels, specifically coal, will continue as the prime source of energy for a considerable future. However Carbon-dioxide emissions from coal based plants has serious „climate ch...
