1. 1. Fuel Transition for Gas Turbines : In a Changing European Energy Landscape

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Lovisa Langerak; [2023]
   Nyckelord :energy technology; gas turbine; energy transition; Europe; green fuels; hydrogen; ammonia; biofuels; energiteknik; gasturbin; energiomställning; Europa; gröna bränslen; vätgas; ammoniak; biobränslen;

   Sammanfattning : The transition to renewable energy sources is vital to mitigate global warming and achieve the climate targets set by the EU. The availability of natural gas in Europe is challenged due to the Russian invasion of Ukraine, leading to a shift towards fossil-free alternatives. LÄS MER

3. 2. Financial viability of producing hydrogen in windfarms in the Nordic region

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Juan Munoz; [2023]
   Nyckelord :Hydrogen; Wind; Energy; Ammonia; Nordic;

   Sammanfattning : With the perspective of a growing hydrogen market that responds to the energy sector requirements for a carbon-free fuel and/or storage method, analyzing the financial viability of producing green hydrogen in the Nordic region is of great importance to understand the possibilities of local supply and the role that the strongly present wind industry can have in it.  Additionally, the possibility of the construction of a dedicated hydrogen pipeline connecting Sweden, Finland, Denmark, and possibly other countries in the Nordic area, changes the previously analyzed scenarios of only local demand, close to production; incorporating this infrastructure into the simulations will shed light upon the possibilities for a Nordic hydrogen market.

4. 3. Offshore Hydrogen Production and Storage for Wave Energy Application : A Techno-Economic Assessment for a Japanese Context

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

   Författare :Andrea Stafverfeldt; [2023]
   Nyckelord :Hydrogen; Green Hydrogen; Hydrogen Storage; Hydrogen Production; Wave Energy; Offshore Hydrogen; Levelized Cost of Hydrogen; Vätgas; Grön vätgas; Vätgaslager; Vätgasproduktion; Vågkraft; Havsbaserad vätgas iv;

   Sammanfattning : There is a well-established market for hydrogen, mainly for refining purposes, producing chemicals, and producing fertilizers. Today, almost all hydrogen is sourced from fossil fuels, with less than 1% of hydrogen sourced from renewable sources. LÄS MER

5. 4. Towards more sustainable dietary choices: Strategies for change in the context of Lucerne, Switzerland

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :André Wismer; [2023]
   Nyckelord :consumer behaviour; food system; dietary choices; meat intake; Earth and Environmental Sciences;

   Sammanfattning : Switzerland's current food system is unsustainable and responsible for 25% of the country's environmental footprint. Half of the greenhouse gas emissions from the Swiss food system are caused by meat and dairy consumption. LÄS MER

7. 5. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Andras Szanthoffer; [2022]
   Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

   Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER
