1. 16. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

   Författare :Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

   Sammanfattning : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

3. 17. Requirement and Availability of Scarce Metals for Fuel-Cell and Battery Electric Vehicles

   Författare :Ingrid Råde; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal requirement; sustainability; fuel cells; batteries; platinum; metal scarcity; resources; electric vehicles; metal availability; industrial ecology;

   Sammanfattning : Battery and fuel-cell electric vehicles (EVs) are considered as a means to meet some of the environmental and resource challenges of todays road vehicle system. EVs have the potential for zero tailpipe emissions as well as an energy efficiency higher than internal combustion engine vehicles and they can be flexible concerning primary energy source. LÄS MER

4. 18. The low-carbon steel industry - Interactions between the hydrogen direct reduction of steel and the electricity system

   Författare :Alla Toktarova; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy; Energy systems modelling; Hydrogen-direct reduction; Steel industry; Electrification;

   Sammanfattning : The European steel industry must achieve deep reductions in CO2 emissions to meet the targets set out in the Paris Agreement. Options for reducing CO2 emissions include electrification, carbon capture and storage (CCS) and the use of biomass. LÄS MER

5. 19. A multi-sector framework for accelerating renewable energy deployment in power, transport and industry

   Författare :Emanuele Taibi; Francesco Fuso-Nerini; Laurens de Vries; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Sammanfattning : Climate change is the defining issue of our time (United Nations, 2018). Renewable energy, combinedwith energy efficiency, can potentially be the most effective solution to address energy-relatedGreenhouse Gas (GHG) emissions. LÄS MER

7. 20. Integrated Motor Drives and Battery Chargers for Electric or Plug-in Hybrid Electric Vehicles

   Författare :Saeid Haghbin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum torque per Ampere strategy.; integrated motor drive and battery chargers; field-oriented control; battery charger; isolated and non-isolated integrated charges; Plug-in vehicles; split-phase PM motor;

   Sammanfattning : Plug-in vehicles, electric vehicles or plug-in hybrid electric vehicles, use grid power to charge the battery. The components in the traction circuit, like the electric motor and the inverter, are not used during the battery charging, so there is a possibility to use them in the charger circuit to reduce the size, weight and price of the on-board charger; that is called an integrated motor drive and battery charger or simply an integrated charger which can be galvanically isolated or non-isolated from the utility grid.
