1. 16. Practical implementation of Bio-CCS in Uppsala : A techno-economic assessment

   University essay from KTH/Energiteknik

   Author : Robert Djurberg; [2020]
   Keywords : BECCS; Bio-CCS; CCS; techno-economic assessment; BECCS; Bio-CCS; CCS; teknoekonomisk analys;

   Abstract : To decrease global warming, bioenergy with carbon capture and storage (Bio-CCS) has been proposed as an effective and necessary tool. Combusting biomass and capturing carbon dioxide (CO2) from the same process results in net negative emissions, hence, reducing the concentration of CO2 in the atmosphere. READ MORE

3. 17. Monovalent selective electrodialysis in greenhouses - An analysis of brackish groundwater and greenhouse wastewater treatment

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Georg Schücking; [2020]
   Keywords : desalination; water treatment; greenhouses; ED; MSED; monovalent selective electrodialysis; groundwater; sodium; nitrate; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

   Abstract : Water use in greenhouse can be optimized by switching to alternative sources of irrigation water and building zero-liquid discharge systems that recirculate greenhouse effluent. The use of brackish groundwater (BGW) has become a popular option for greenhouses that have adopted reverse osmosis (RO) to reduce the salinity of their source water. READ MORE

4. 18. Energy savings and CO2 emissions related to measures on an old apartment building

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Johan Helin; [2020]
   Keywords : energy; savings; emission; CO2; apartment building; measures;

   Abstract : There is a clear focus on the environmental question in today’s society. The awareness of energy consumption and emission of greenhouse gases is growing which causes the urge to increase energy efficiency and decrease the emissions. This is applied in all sectors, housing being one of them. READ MORE

5. 19. Development of evaluation tools as an approach to pre-design district energy systems : Qualitative modeling and performance simulation using OpenModelica

   Abstract : Cities and districts contribute to a large fraction of the total energy consumption in Sweden. The residential- and service sector accounted for almost 40% of the total energy consumption in 2018. The increasing urbanization also puts more importance on the energy supply, distribution and consumption in these areas. READ MORE

6. 20. Tesla Valve for Hydrogen Decompression : Fluid Dynamic Analysis
