1. 1. Mobilized Thermal Energy Storage for Heat Recovery for Distributed Heating

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

   Sammanfattning : 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.

3. 2. Economic and Environmental Benefits of CHP-based District Heating Systems in Sweden

   Författare :Shahnaz Amiri; Björn G. Karlsson; Louise Trygg; Mats Westermark; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO2) and other greenhouse gases and their impact on climate change.

4. 3. Retrofitting CHP Plant and Optimization of Regional Energy System

   Författare :Song Han; Jinyue Yan; Eva Thorin; Mats Westermark; Mälardalens högskola; []
   Nyckelord :annual performance; combined heat and power; drying; ethanol; integration; part-load.; årliga prestation; kraftvärme; torkning; etanol; integration; del-last.; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The use of biomass-based combined heat and power (CHP) plants is considered by the EU administration to be an effective way to increase the use of renewables in the energy system, to reduce greenhouse gas emissions and to alleviate the dependency on imported fossil fuels. At present in Sweden, most of the CHP plants are operated in part-load mode because of variations in heat demand. LÄS MER

5. 4. Power to gas : Bridging renewable electricity to the transport sector

   Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

   Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER

7. 5. Turbomachinery in Biofuel Production

   Författare :Martin Görling; Mats Westermark; Simon Harvey; Bengt Hylander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-Methanol; Biomass; Gasification; Humidification; Hybrid Cycle; SNG; Chemical energy engineering; Kemisk energiteknik;

   Sammanfattning : The aim for this study has been to evaluate the integration potential of turbo-machinery into the production processes of biofuels. The focus has been on bio-fuel produced via biomass gasification; mainly methanol and synthetic natural gas. The research has been divided into two parts; gas and steam turbine applications. LÄS MER
