2. 1. The impact of a widened energy system boundary on cost effectiveness

   Author : Alemayehu Gebremedhin; Olof Björkqvist; Linköpings universitet; []
   Keywords : ;

   Abstract : This study describes the impact of widened system boundaries in the choice of heat generating plants, the total cost of the defined energy system and the use of combined heat and power (CHP) production plants. The economic and environmental benefits of co­ operation between public utilities and industries and the importance of enlarged system boundaries are shown in the different case-studies. READ MORE

4. 2. Assessment of existing and potential developments of district-heating systems

   Author : Elsa Fahlén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuel; external costs; combined heat and power; socio-economic cost-effectiveness; district heating; ExternE; social costs; MARTES; bio transport fuel; biomass gasification;

   Abstract : District heating (DH) may play an important role for achieving the EU goal of a secure, competitive and sustainable energy supply. DH benefits from the possibilities of utilising local resources such as municipal solid waste and other low-quality fuels, as well as low-cost waste heat from industries and from combined heat and power plants (CHP).

5. 3. Biobased Combined Heat and Power Production in Sweden – Opportunities for and Challenges to Sustainability from the Plant Operator Perspective

   Author : Malin Pettersson; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Biobased economy; Decarbonisation; Combined heat and power plant; Sustainability;

   Abstract : Although combined heat and power (CHP) production in Sweden is already largely decarbonised, this technology has further potential to alleviate pressing environmental concerns. Today, biobased CHP plants connected to district heating (DH) grids dominate the Swedish residential heating sector. READ MORE

6. 4. Integrating Biomass in Existing Natural Gas-Fired Power Plants

   Author : Erik Pihl; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

   Abstract : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

7. 5. Effect of fuel composition and combustion conditions on phosphorus behavior during combustion of biomass

   Author : Joel Falk; Marcus Öhman; Anita Petterson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Abstract : Due to concerns for climate change and future supply of phosphorus fertilizer within agriculture, there has been an increased interest in the combustion of phosphorus containing waste residues and opportunity biomass fuels. Previous research has shown that during combustion, phosphorus has large impact on ash transformation reactions and may decrease or increase ash-related problems such as slag formation and bed agglomeration.
