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

   University essay from Lunds universitet/Kemiska institutionen

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

   Abstract : 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. READ MORE

3. 2. Mathematical modelling of Degussa Furnace

   Abstract : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. READ MORE

4. 3. Compressed air energy storage : Process review and case study of small scale compressed air energy storage aimed at residential buildings

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Evelina Steen; Malin Torestam; [2018]
   Keywords : compressed air energy storage CAES ; electrical energy storage EES ; artificial air storage; thermodynamic analysis; economic evaluation; tryckluftsenergilagring CAES ; elektrisk energilagring EES ; artificiell luftförvaring; termodynamisk analys; ekonomisk utvärdering;

   Abstract : The potential for electrical energy storage to both provide services to the electrical grid and help to better integrate renewable energies in the electrical system is promising. This report investigates one type of storage, compressed air energy storage (CAES), where energy is stored by compressing air during hours of low electricity demand and later expanding the air to generate electricity during high demand hours.

6. 5. Hybridization with CSP in a Cuban sugar mill

   University essay from KTH/Energiteknik

   Author : Iris Vesterberg; Sofia Westerlund; [2018]
   Keywords : Cuban sugar cane industry; bagasse; concentrating solar power; hybrid power plant; electricity generation;

   Abstract : Kuba har i dagsläget ett högt beroende av importerad olja, för att tillgodose sin växande efterfrågan på elektricitet. Importen sker främst från Venezuela. Detta beroende gör Kuba känsligt för ändringar i oljepriser samt det politiska klimatet. Den nuvarande krisen i Venezuela har haft en betydande inverkan på Kubas elproduktion. READ MORE
