   Författare :Davi Rodrigues Damasceno; Fredrik Johansson; Johan Spross; Rafael Jimenez; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lined rock cavern; reliability-based design; analytical modeling; finite element modeling; underground gas storage; Inklädda bergrum; tillförlitlighetsbaserad design; analytisk modellering; finita elementmodellering; underjordisk gaslagring; Soil and Rock Mechanics; Jord- och bergmekanik;

   Sammanfattning : The storage of large quantities of hydrogen gas in underground lined rock caverns (LRCs) could contribute to an efficient supply of fossil-free energy. The consequences of failure of such storage can be catastrophic, so representative predictive models and a small probability of failure are needed for the LRC design. LÄS MER

4. 3. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; climate change; optimisation; genetic algorithms; applied thermodynamics; Thermal engineering; AZEP; GTPOM; gas turbine; CO2 capture; thermoeconomy; termodynamik;

   Sammanfattning : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. LÄS MER

5. 4. Numerical modeling of coupled thermo-hydro-mechanical processes in geological porous media

   Författare :Fuguo Tong; Lanru Jing; Chin-Fu Tsang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-hydro-mechanical processes; Porous geologicalmedia; Numerical modeling; FEM; Multiphase flow; Effective thermal conductivity; Water retention curve; Radioactive waste repositories; Bentonite; ; Geoengineering; Geoteknik;

   Sammanfattning : Coupled Thermo-Hydro-Mechanical (THM) behavior in geological porous media has been a subject of great interest in many geoengineering disciplines. Many attempts have been made to develop numerical prediction capabilities associated with topics such as the movement of pollutant plumes, gas injection, energy storage, geothermal energy extraction, and safety assessment of repositories for radioactive waste and spent nuclear fuel.

7. 5. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

   Författare :Benoît Dessirier; Jerker Jarsjö; Andrew Frampton; Stefan Finsterle; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal; Physical Geography; naturgeografi;

   Sammanfattning : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. LÄS MER
