1. 21. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

   Författare :Gabriel Auziane; Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

   Sammanfattning : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. LÄS MER

3. 22. Industrial energy efficiency improvement – the role of policy and evaluation

   Författare :Christian Stenqvist; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement.; Pulp and paper; Decarbonisation; EU ETS; Energy management; Voluntary Agreement; Evaluation; Policy; Industrial energy efficiency;

   Sammanfattning : At EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. LÄS MER

4. 23. 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.

5. 24. Partial carbon capture – an opportunity to decarbonize primary steelmaking

   Författare :Max Biermann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; amine absorption; partial CO2 capture; process industry; cost estimation; CCS; steel making;

   Sammanfattning : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. LÄS MER

7. 25. Simulation model of a ship’s energy performance and transportation costs

   Författare :Fabian Tillig; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed optimization; energy efficiency; wind-assisted propulsion.; performance prediction; energy systems model; ship design;

   Sammanfattning : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.
