1. 1. Non-geological hydrogen storage for fossil-free steelmaking

   Författare :Joakim Andersson; Stefan Grönkvist; Simon Harvey; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen storage; fossil-free; steelmaking; industrial decarbonization; hydrogen direct reduction; Chemical Engineering; Kemiteknik;

   Sammanfattning : In the last half-century, global steel use has increased more than threefold and further growth is expected, particularly in developing economies. However, steelmaking is currently responsible for 7% of the global net carbon dioxide (CO2) emissions, and any substantial further optimization of existing processes that utilize fossil fuels for iron ore reduction is infeasible.

3. 2. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

   Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

   Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

4. 3. 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

5. 4. Improving the performance of combined heat and power plants through integration with cellulosic ethanol production

   Författare :Fredrik Starfelt; Yan Jinyue; Eva Thorin; Simon Harvey; Mälardalens högskola; []
   Nyckelord :Combined heat and power; Polygeneration; biofuel; bioenergy; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Today’s biomass-fired combined heat and power (CHP) plants have surplus heat production capacity during warmer times of the year. In order to allow them to increase their electricity production, it is essential to find a use for the surplus heat. LÄS MER

7. 5. System studies of forest-based biomass gasification

   Författare :Elisabeth Wetterlund; Mats Söderström; Magnus Karlsson; Simon Harvey; Pål Börjesson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; second-generation biofuels; global CO2 emissions; energy system optimisation;

   Sammanfattning : Bioenergy will play an important role in reaching the EU targets for renewable energy. Sweden, with abundant forest resources and a well-established forest industry, has a key position regarding modern biomass use. LÄS MER
