1. Operational stability of lean premixed combustion in gas turbines : an experimental study on gaseous alternative fuels
Sammanfattning : 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. LÄS MER
2. Mobility Management and Climate Change Policies
Sammanfattning : 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.

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

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

5. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?
Sammanfattning : 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. LÄS MER
