2. 21. Decision Support for Energy Transition : Application of Multi-criteria Decision Making on Danish Residential Heating

   Author : Qianyun Wen; Yang Liu; Olof Hjelm; Xiufeng Liu; Pascale Zarate; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : With the increasing awareness of the impact of climate change, there has been more intention to reduce greenhouse gas emissions and achieve carbon neutrality targets. However, as one essential element for human well-being, residential heating remains a major contributor to global greenhouse gas emissions. READ MORE

4. 22. CFD Modelling of Hydrogen Rich Biomass Syngas Combustion

   Author : Nikolaos Papafilippou; Rikard Gebart; Kentaro Umeki; Muhammad Aqib Chishty; Christophe Duwig; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; RANS; LES; FGM; Turbulent Combustion; Numerical Combustion; Swirling Flows; Gas Turbines; Biomass Syngas; Hydrogen; Energiteknik; Energy Engineering;

   Abstract : The loss of biodiversity, due to pollution and global warming, is more important and relevant now than it has ever been. Man made climate warming has its roots in the huge amount of CH4 and CO2 emissions, which have increased by 47% and 156% respectively since 1750. READ MORE

5. 23. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions

   Author : Xin Liu; Förbränningsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Combustion; Gas Turbine; Laser diagnostic; Fuel flexibility; Plasma-assisted combustion; Ammonia flame; High pressure;

   Abstract : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. READ MORE

6. 24. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia

   Author : Johnny Villarroel-Schneider; Anders Malmquist; Andrew R. Martin; Monica Odlare; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bolivia; polygeneration; trigeneration; productive sector; dairy; biogas; electricity; refrigeration; multiservice; performance; techno-economic; Bolivia; poligeneración; trigeneración; sector productivo; lechería; biogás; electricidad; refrigeración; multiservicio; eficiencia; tecno-económico; Energiteknik; Energy Technology;

   Abstract : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.

7. 25. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts

   Author : Bo Wei; Reza Fakhrai; Torsten Fransson; Nader Jand; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conversion; solar; ceria; thermogravimetric test; exergy analysis; simulink; fluidized bed; gas-solid flow; simulation; Energiteknik; Energy Technology;

   Abstract : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. READ MORE
