  2. 1. Production planning of CHP plants integrated with bioethanol production and local renewables

    Author : Mahsa Daraei; Eva Thorin; Anders Avelin; Erik Dotzauer; Natasa Nord; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CHP; Energy systems; Optimization; Polygeneration; Production planning; Renewable resources; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Production planning of an energy system is dependent on parameters such as energy demand and energy conversion technologies, which are influential in making decisions on operation strategy and optimal performance of the system. In accordance with the European Union energy policy, the share of renewable resources in the energy supply is growing. READ MORE

  4. 2. New Opportunities and System Consequences for Biomass Integrated Gasification Technology in CHP Applications

    Author : Åsa Marbe; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 emissions; biomass CHP; NGCC CHP; systems analysis; biomass gasification;

    Abstract : There are currently many driving forces for increasing electricity production in biomass CHP plants. This thesis presents techno-economic and CO2 emissions analyses for biomass integrated gasification technology in CHP applications. READ MORE

  5. 3. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation

    Author : Kristina Difs; G. Björn Karlsson; Louise Trygg; Thomas B. Johansson; Linköpings universitet; []
    Keywords : District heating; combined heat and power; carbon dioxide emissions; optimisation; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. READ MORE

  6. 4. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

    Author : Håkan Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

    Abstract : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. READ MORE

  7. 5. Rational bioenergy utilisation in energy systems and impacts on CO2emissions

    Author : Bertil Wahlund; KTH; []
    Keywords : CO2 reduction; energy system; biofuel; CHP; refining; fuel pellets; ethanol; methanol; DME; fuel substitution; sewage water; nitrification;

    Abstract : The increased concentration of greenhouse gases in theatmosphere, in particular CO2, is changing the Earth’s climate. Accordingto the Kyoto protocol, where the international community agreedon binding emission targets, developed countries are committedto reduce their greenhouse gas emissions. READ MORE
