2. 1. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides

   Author : Akshay Krishna Ammothum Kandy; Peter Broqvist; Jolla Kullgren; Eddie Wadbro; Ben Hourahine; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Force fields; Electronic structure calculations; CCS; DFTB; CCS Q; repulsive fitting; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. READ MORE

4. 2. Opportunities and uncertainties in the early stages of development of CO2 capture and storage

   Author : Mårten Lind; Mats Westermark; Mohsen Assadi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptance; cement; CCS; CO2 capture and storage; early opportunities; enhanced oil recovery; expert opinions; hybrid power cycles; optimism; oxyfuel combustion; pressurised fluidised bed combustion; pilot plant; potassium carbonate; risk; Sargas; scenario studies; scientific uncertainty; stakeholder perceptions; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

   Abstract : The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. READ MORE

5. 3. CO2 transportation infrastructure and biomass supply systems for carbon capture and storage - A modeling study of Swedish industry

   Author : Sebastian Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; cost optimization; infrastructure; incentives; CCS; biomass supply; industry; CO2 transportation;

   Abstract : Rapid decarbonization of the industrial sector is crucial if the world is to manage to meet the target set in the Paris Agreement of limiting global warming to “well below 2°C”. The main technological pathways for achieving a low-carbon industry are the substitution of fossil feedstocks and energy supply with bio-based alternatives, electrification, and implementing carbon capture and storage (CCS).

6. 4. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation

   Author : Max Biermann; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon allocation; Partial CO2 capture; process industry; techno-economic assessment; CCS; heat recovery; amine absorption;

   Abstract : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.

7. 5. Integrating the Z notation and behavioural formalisms

   Author : Kenji Taguchi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Integrated Formal Methods; CCS; Z; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; datorteknik; Computer Systems;

   Abstract : The last several years have witnessed an increasing interest in integrating different formalisms in the formal methods research community. Particularly a number of notations have been proposed by different authors which integrate existing state-based formalisms such as Z, VDM and B and behavioural formalisms such as CCS, CSP and Statecharts.
