    Sammanfattning : Considering the growing importance of the electricity sector in the worldwide decarbonisation efforts, as well as large volumes of energy consumed by the commercial and industrial (C&I) sector, corporate power procurement is found to be a significant contributor to building a net zero economy. Within this topic, hourly matching of carbon-free electricity supply with demand, or 24/7 Carbon-free Energy (24/7 CFE), is identified as a next-generation power procurement framework, with growing interest from a wide range of stakeholders in the energy sector and benefits backed by robust research evidence.

    Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER

  4. 4. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arjun Monga; [2023]
    Nyckelord :coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER

  5. 5. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

    Master-uppsats, KTH/Materialvetenskap
