  1. 1. Dynamics of Energy Systems - Methods of analysing technology change

    Författare :Lena Neij; Internationella miljöinstitutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER

  3. 2. Molecular Solar Thermal Energy Storage System: Evaluation of Different Candidates

    Författare :Zhihang Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage and release; Vinylheptafulvene; Catalyst; Quadricyclane; Solar Energy; Thermal dynamics; Molecular switches; Azobenzene; Norbornadiene; Energy conversion; Dihydroazulene;

    Sammanfattning : The development of solar energy can potentially meet the growing requirements for a global energy system beyond fossil fuels, however necessitates new scalable technologies for solar energy storage. One approach is the development of energy storage systems based on molecular photoswitches, so-called molecular solar thermal energy storage (MOST). LÄS MER

  4. 3. Energy analysis for sustainable mega-cities

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

    Sammanfattning : As technology is increasingly used in mobile settings, energy and battery management is becoming a part of everyday life. Many have experienced how quickly a battery can be depleted in a smartphone, laptop or electric cars, sometimes causing much distress. LÄS MER

  7. 5. Hydrogen in the European energy system - The cost dynamics and the value of time-shifting electricity generation

    Författare :Simon Öberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost; energy systems modeling; Hydrogen; gas turbine; system dynamics; time-shifting;

    Sammanfattning : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.
