   Nyckelord :Bio-Carbon Capture and Storage Bio-CCS ; Carbon Capture and Storage CCS ; Carbon Capture and Utilisation CCU ; Carbon Dioxide CO2 ; Climate Change; Climate Policy; Costs regarding Carbon Capture and Storage; Direct Air Capture DAC ; Geological Storage; Greenhouse Gas es GHG ; Policy regarding Carbon Capture and Storage; Bio-Carbon Capture and Storage Bio-CCS ; Carbon Capture and Storage CCS ; Carbon Capture and Utilisation CCU ; Koldioxid CO2 ; Klimatförändring; Klimatpolitik; Kostnad för Carbon Capture and Storage; Direct Air Capture DAC ; Geologisk lagring; Växthusgas er ; Reglering för Carbon Capture and Storage;

   Sammanfattning : The Paris Agreement aims to limit global warming to 1.5 degrees Celsius, and Sweden has set a goal toreach net-zero emissions by 2045. Carbon Capture and Storage (CCS) is one method that can reducecarbon dioxide emissions. LÄS MER

4. 3. Speciell relativitetsteori i gymnasieskolan

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikundervisningens didaktik

   Författare :Vendla Niklasson; [2022]
   Nyckelord :speciell relativitetsteori; fysikdidaktik; einsteins tåg; gymnasieskolan; tvillingparadoxen;

   Sammanfattning : Special relativity is a subject that attracts interest among students, but there are many things that make students experience it as difficult. As a physics teacher, it is important to both have a solid base of knowledge in physics as well as educational knowledge within the subject. LÄS MER

5. 4. Strategies for regional deployment of hydrogen infrastructure : The case of North Rhine-Westphalia, Germany

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

   Författare :Roberto Di Molfetta; [2022]
   Nyckelord :Hydrogen; Infrastructure rollout; Supply chain pathways; Mobility; Hydrogen buses.;

   Sammanfattning : In response to the growing urge towards decarbonisation, more and more initiatives have been set to reduce and/or compensate the level of CO2 (carbon dioxide) emitted by human activities, which is one of the main responsible of the incumbent threats of “global warming” and “climate change”. “Climate neutrality by 2050” has become a decisive topic for political agendas worldwide and, against that background, the hydrogen economy can play a significant role.

7. 5. Simulation of air quality in underground train stations

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Benjamin Söderberg; [2020]
   Nyckelord :PM10; aerosols; air pollution; particulate matter; emission factors; underground train station; PM10; luftkvalité; tåg; emissionsfaktorer; underjordiska tågstationer;

   Sammanfattning : Particulate matter (PM) is a widespread air pollutant of microscopic particles that are suspended in the atmosphere. There is high concentration of PM in underground train stations and tunnels. The concentration of particulate matter (PM10) measured in Stockholm’s metro varies significantly between day and nighttime traffic of trains. LÄS MER
