  1. 1. Integrating Heat Pumps into Smart Grids

    Author : David Fischer; Björn Palm; Georges Laurent; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Abstract : Transforming our energy system towards 100% renewable energy sources requires radical changes across all energy sectors. Heat pumps as efficient heat generation technology link the electricity and heat sector. From 2010 to 2015 between 750,000 and 800,000 heat pumps have been sold every year across Europe. READ MORE

  2. 2. Aerodynamic Design and Aeromechanical Analysis of Mixed and Radial Flow Turbines : A study on meanline method, stator tilting endwall design and forced response analysis

    Author : Yang Gao; Andrew R. Martin; Jens Fridh; Damian Vogt; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbomachinery; CFD; aerodynamics; aeromechanics; mixed flow turbine; Energiteknik; Energy Technology;

    Abstract : In this energy transition era, turbocharging is still an important technology for the automotive industry to reduce fuel consumption and lower emissions in its vehicles. This importance can be seen from both conventional fossil-fuel powertrains, and emerging applications, such as increased utilization of biofuels along with hydrogen fuel cells. READ MORE

  3. 3. Application of Rare-Earth Doped Ceria and Natural Minerals for Solid Oxide Fuel Cells

    Author : Yanyan Liu; Andrew R. Martin; Wujun Wang; Shanwen Tao; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-temperature solid oxide fuel cells; Doped ceria; Material characterizations; Electrochemical performances; Natural minerals; Lågtemperatur fastoxidbränsleceller; Dopade ceriumoxid; Materialkarakteriseringar; Elektrokemiska prestanda; Naturliga mineraler.; Energiteknik; Energy Technology; Materials Science and Engineering; Teknisk materialvetenskap; Chemical Engineering; Kemiteknik;

    Abstract : Although solid oxide fuel cell (SOFC) technology exhibits considerable advantages as compared to other energy conversion devices, e.g. high efficiency, low emission and fuel flexibility, its high operating temperature leads to rapid component degradation and has thus hampered commercialization.
