2. 31. REACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA : Injection into and leakage from geological reservoirs

   Author : Nawaz Ahmad; Anders Wörman; Auli Niemi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 geological storage and safety; leakage of brine saturated with dissolved CO2; reactive transport; fracture; advection; dispersion and diffusion; sorption; carbonate minerals kinetic reactions; calcite; dolomite; siderite; porosity; permeability; heat transport; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : The geological sequestration of carbon dioxide (CO2) is one of the options of controlling the greenhouse gas emissions. However, leakage of CO2 from the storage reservoir is a risk associated with geological sequestration. Over longer times, large-scale groundwater motion may cause leakage of dissolved CO2 (CO2aq).

4. 32. Borehole heat store design optimization

   Author : Bo Nordell; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. READ MORE

5. 33. Brazilian land use policies and the development of ecosystem services

   Author : Flavio L. M. Freitas; Ulla Mörtberg; Gerd Sparovek; Martin Persson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; Land use policy; Forest protection; Ecosystem services; Biodiversity; Offsetting of legal reserves; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : Concerns related to global environmental changes due to land use changes have been driving international communities towards more sustainable land use systems. Brazil is a country of global strategic importance in this matter considering that it is the nation with the largest extension of preserved tropical native vegetation, recognised for its ecosystem services and high and unique biodiversity.

6. 34. Topographic Control of Groundwater Flow

   Author : Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

   Abstract : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. READ MORE

7. 35. Applying Industrial Ecology in Urban Planning for the local integration of data centers

   Author : Cristina Ramos Caceres; Adolfo Sotoca; Marcus Sandberg; Cornelia Redeker; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data centers; Industrial Ecology; Urban Planning; Spatial Planning; Energy Planning; Arkitektur; Architecture;

   Abstract : The data center industry’s rapid development raises questions about how to regulate data center locations and expansion, becoming a matter of high concern regarding Urban Planning. Data center facilities are commonly located and scaled (regarding power and size) responding to business profitability interests steered by the global market. READ MORE
