1. 41. Investigation of nitrogen recovery from concentrated wastewater

   Författare :Aubrey Beckinghausen; Monica Odlare; Eva Thorin; Sebastian Schwede; Ershad Ullah Khan; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitrogen; ammonium; recovery; circular economy; wastewater; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Nitrogen recovery from wastewater treatment for fertilizers is a research topic that exists at the intersection of multiple topics important to the future of sustainable society. First, nitrogen recovery from wastewater implies a departure from the current methods of nitrogen mitigation, which involve nitrogen removal by conversion of various aqueous species to inert nitrogen gas.

3. 42. Evaluation of Modular Thermally Driven Heat Pump Systems

   Författare :Corey Blackman; Eva Thorin; Chris Bales; Christian Schweigler; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption heat pump; sorption module; thermochemical energy storage; artificial neural network; built environment; solar energy; gas-driven heat pump; solar cooling; heating and cooling; renewable energy; energy efficiency; experimental; simulation; analytical; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

   Sammanfattning : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.

4. 43. Building as active elements of energy systems

   Författare :Mehmet Börühan Bulut; Björn Karlsson; Fredrik Wallin; Peter Stigson; Jenny Palm; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart grid; smart home; cooperation; energy; buildings; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Buildings account for approximately 40% of the energy demand and 33% of the total greenhouse gas emissions in the European Union. Accordingly, there are several efforts that target energy efficiency in buildings both at the European and Swedish levels. The role of buildings in climate change mitigation, however, is not limited to energy savings. LÄS MER

5. 44. PV water pumping systems for agricultural applications

   Författare :Pietro Elia Campana; Jinyue Yan; Hailong Li; Lawrence Kazmerski; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Grassland and farmland degradation is considered as one of the worst environmental and economic threats for China. The degradation process negatively affects food and water security, economy, society and climate changes. LÄS MER

7. 45. Production Planning of CHP plants in transition towards energy systems with high share of renewables

   Författare :Mahsa Daraei; Eva Thorin; Pietro Elia Campana; Anders Avelin; Louise Ödlund; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The global energy system is undergoing a transformative change towards renewable energies. The share of Renewable Energy Sources (RES) and bioenergy in the world’s primary energy use has increased in the recent years. LÄS MER
