2. 1. Evaluating the utilisation of industrial excess heat from an energy systems perspective

   Author : Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

   Abstract : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. READ MORE

4. 2. Sustainable production of bio-energy products in the sawmill industry

   Author : Anna Vidlund; KTH; []
   Keywords : sawmill industry; energy efficiency; heat recovery; integration; biofuel; upgrading; district heating; fuel pellets; CHP; VOC; CO2;

   Abstract : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. READ MORE

5. 3. Mobilized Thermal Energy Storage for Heat Recovery for Distributed Heating

   Author : Weilong Wang; Jinyue Yan; Erik Dahlquist; Jenny Holgersson; Hongxing Yang; Björn Karlsson; Mats Westermark; Louise Trygg; Mälardalens högskola; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Conventional energy sources—oil and electricity—dominate the heat supply market. Due to their rising costs and their negative environmental effects on global climate change, it is necessary to develop an alternative heat supply system featuring low cost, high energy efficiency and environment friendliness.

6. 4. Heat driven cooling in district energy systems

   Author : Magnus Rydstrand; KTH; []
   Keywords : District heating; district cooling; thermal storage; humidified gas turbines; combined heat and power; cooling;

   Abstract : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. READ MORE

7. 5. Preparation and performance of energy storage materials and application for recovery of industrial waste heat

   Author : Weilong Wang; Jinyue Yan; Fredrik Setterwall; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase change materials; Polyethylene glycol; Silicon dioxide; Form-stable; Thermal conductivity; Expanded graphite; Industrial heat; M-TES; ; Chemical energy engineering; Kemisk energiteknik;

   Abstract : Due to the rapid increase of energy consumption and the environmental concerns on climate change caused by the fossil fuel combustion, it becomes a big issue on how to use alternative renewable energy resources to replace fossil fuel and to improve energy utilization efficiency. In Sweden, there are plenty of detached buildings without connection with district heating (DH) network, which use oil to supply the hot water for space heating and tap water. READ MORE
