1. 16. Design of a Polygeneration system in Filipinas ETCR, Colombia

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Germán Ropero Pérez; [2021]
   Keywords : ;

   Abstract : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

3. 17. A comparative Life Cycle Assessment (LCA) study of centralized and decentralized wastewater heat recovery in Stockholm, Sweden

   University essay from KTH/Energiteknik

   Author : Deniz Pektas; [2021]
   Keywords : ;

   Abstract : The cities bear a large role in the climate crisis. However, this also means that they have a big potential in the transition towards sustainable communities and a sustainable world. Up to 90 % of energy use within the urban water cycle is allocated to hot water heating for end users. READ MORE

4. 18. Improved prediction of biogas production at Uddebo wastewater treatment plant : Substrate modelling in SIMCA

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Isak Gullman; [2021]
   Keywords : Anaerobic digestion; Biogas; Industrial waste; Modelling; Sewage sludge;

   Abstract : Anaerobic digestion is a complex process, dependent on multiple factors, which can be made more stable and efficient with the help of process models. A more stable process could reduce biogas torching, which increases the amount of renewable energy available for heat- and electricity production and vehicle fuel. READ MORE

5. 19. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Virginia Tosi; [2021]
   Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

   Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

6. 20. Power-to-Gas and zero-emission buses in Uppsala : challenges and Opportunities from a techno-economic perspective

   University essay from SLU/Dept. of Energy and Technology

   Author : Mårten Rosell; [2021]
   Keywords : Power-to-gas; bränsleceller; medicinsk syrgas; modellering; lönsamhet;

   Abstract : This thesis has explored the use of power-to-gas technology as a means to produce hydrogen for fuel cell electric buses. The municipal council of Uppsala are looking at options to electrify the local city and regional bus fleet but have been faced with power capacity constraints on the local electrical grid. READ MORE
