  2. 1. Operational stability of lean premixed combustion in gas turbines : an experimental study on gaseous alternative fuels

    Author : Parisa Sayad; Kraftverksteknik; []
    Keywords : Premixed Combustion; Syngas; Swirl Stabilized; Chemical Kinetics; Flashback; Lean Blowout; Autoignition; OH*-chemiluminescence;

    Abstract : World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. READ MORE

  4. 2. Mobility Management and Climate Change Policies

    Author : Markus Robèrt; Folke Snickars; Tom Rye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development SSD ; Backcasting; Greenhouse gas emissions; Traffic planning; Company travel planning; Mobility Management; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : Globally, the transport system faces a paradigmatic shift where, in addition to increased local traffic problems, climate change and depletion of fossil oil reserves will foster a successive transition to renewable fuels and a need for more resource-efficient mobility management and communication alternatives. Foresighted countries, cities or companies taking the lead in adapting to these tougher conditions might well not only solve those problems, but also turn the problems into business advantages.

  5. 3. Large scale renewable energy deployment - Insights offered by long-term energy models from selected case studies

    Author : Constantinos Taliotis; Mark I. Howells; Theodoros Zachariadis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable energy integration; long-term energy models; gas reserves; policy insights; cost optimization; electricity trade; Energiteknik; Energy Technology;

    Abstract : The United Nations’ Sustainable Development Goal 7 (SDG7) of Agenda 2030 calls for an increase in the use of renewable energy sources, among other targets. The percentage of fossil fuel-fired thermal generation for electricity is increasingly being reduced as renewable energy technologies (RET) advance in cost-competitiveness, and as greenhouse gas and industrial air pollutant emission limits become more stringent.

  6. 4. Adsorption of water, carbon dioxide and methane in zeolite ZSM-5 studied using in-situ ATR-FTIR spectroscopy

    Author : Lindsay Ohlin; Zoltán Bacsik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : Global warming is believed to be caused by the extensive emission of greenhouse gases, such as carbon dioxide, into the atmosphere by combustion of fossil fuels, such as coal, oil and natural gas.To reduce the emission of carbon dioxide and hence avoid global warming, alternative fuels derived from renewable resources are desired.

  7. 5. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

    Author : Sudhanshu Pawar; Avdelningen för kemiteknik; []
    Keywords : Caldicellulosiruptor owensensis; Caldicellulosiruptor saccharolyticus; hydrogen; volumetric hydrogen productivity; biofilm; osmotolerance; wheat straw hydrolysate; evolutionary engineering; CSTR; UA reactor and uracil auxotrophy;

    Abstract : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. READ MORE
