  1. 1. Kolets återkomst : Koldioxidavskiljning och lagring i vetenskap och politik

    Författare :Anders Hansson; Jonas Anshelm; Mats Westermark; Alf Hornborg; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Carbon capture; carbon storage; coal power; CCS; energy politics; climate politics; scenario; ecological modernization; Koldioxidavskiljning; koldioxidlagring; kolkraft; CCS; ekologisk modernisering; energipolitik; klimatpolitik; scenario; Technology and social change; Teknik och social förändring;

    Sammanfattning : I denna avhandling studeras en ny teknik för att hantera växthuseffekten. Den nya tekniken heter koldioxidavskiljning och lagring (CCS) och granskades av FN:s klimatpanel 2005 och tillskrevs då möjligheterna att stå för 15-55% av alla CO2-reducering fram till 2100 och detta till en 30% lägre kostnad än vad som annars vore möjligt.

  3. 2. Mesoporous Materials for Fast Charging Electrochemical Energy Storage

    Författare :Giulio Calcagno; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; electrochemical energy storage; redox-active electrolytes; mesoporous carbon; hybrid supercapacitors; fast charging storage; ordered mesoporous materials; mesoporous titanium dioxide; lithium-ion battery;

    Sammanfattning : High performing electrochemical energy storage (EES) devices are needed to cope with the increasing energy requirements of modern society. Electrode materials must store lots of energy, charge/discharge fast and be environmentally friendly. LÄS MER

  4. 3. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER

    Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER

  7. 5. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach

    Författare :Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Mani Sudhagar; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid biofuels; densified biomass; heat generation; off-gas emissions; carbon monoxide; carbon dioxide; methane; fatty and resin acids; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. LÄS MER
