  1. 1. Travelling Business Models : On adapting business models to new contexts

    Författare :Kajsa Ahlgren Ode; Innovationsteknik; []
    Nyckelord :affärsmodell; innovation; översättning; hållbarhet; process; solenergi; business model; innovation; translation; sustainability; process; solar energy;

    Sammanfattning : How business models are configured can provide one solution to bringing forward sustainable innovations and transforming businesses and industries so that they become more sustainable. Creating a shift in the energy sector’s use of renewable sources is of particular importance since the energy sector is the source of one-fourth of all global greenhouse gas emissions. LÄS MER

    Sammanfattning : Nearly all the 1.3 billion people in the world with no electricity access live in developing countries. On the one hand, electricity is a basic need. On the other hand, the environment should not be further damaged. LÄS MER

  7. 5. Development of a Novel Gas Turbine Simulator for Hybrid Solar-Brayton Systems

    Författare :Tianyao Pan; Björn Laumert; Wujun Wang; Konstantinos Kyprianidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine simulator; concentrating solar power; hybrid solar-Brayton system; pressure controller; choked nozzle; Programmable logic controller; proportional solenoid valve.; Gasturbinsimulator; koncentrerad solenergi; hybrid solenergi-Brayton-system; tryckregulator; strypt munstycke; programmerbar logikkontroller; proportionell magnetventil.; Energiteknik; Energy Technology;

    Sammanfattning : Hybrid solar-Brayton systems utilize both solar thermal energy and supplementary renewable fuels to provide controllable and dispatchable power output, which renders them a promising way to meet the growing energy demand and reduce the carbon footprints. However, existing testing facilities for key components in such hybrid systems often fail to accomplish the testing requirements, hence impeding the improvement of the renewable energy share and the overall efficiency.
