  1. 1. Cost-effective fuel and technology choices in the transportation sector in a future carbon constrained world: Results from the Global Energy Transition (GET) model

    Author : Maria Grahn; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy prices; CSP; CO2 emissions; hydrogen; CCS; carbon tax; biomass; carbon leakage; liquid biofuels; global energy systems modeling; transportation; passenger vehicles;

    Abstract : This thesis analyzes future fuel and technology choices focusing on transport in a carbon constrained world. The analysis tool used in all five appended papers is the cost-minimizing Global Energy Transition (GET) model. READ MORE

  2. 2. Benefits of Integrated Upgrading of Biofuels in Biorefineries - Systems Analysis

    Author : Eva Ingeborg Elisabeth Andersson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; systems analysis; biorefinery; process integration; CO2 emissions; biofuels;

    Abstract : As a result of increasing concerns about climate change, there is considerable current interest in increasing use of CO2-neutral biofuel in the energy system. Increased use of biomass fuel requires that it be upgraded in order to facilitate transportation and distribution to end-users. READ MORE

  3. 3. Conditions for resource-efficient production of biofuels for transport in Sweden

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Carolina Ersson; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. READ MORE

  4. 4. Cost-effective fuel choices in the transportation sector under stringent CO2-emission reduction targets - Global energy systems modelling

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Maria Grahn; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global energy systems; carbon dioxide emissions; biomass; liquid biofuels; primary energy price; transportation sector; hydrogen; carbon tax; energy scenarios;

    Abstract : This thesis analyzes the worlds future energy supply in general, and cost-effective fuel choices in the transportation sector in particular, under stringent CO2 constraints. The analysis is carried out with the help of a global energy systems model (GET), developed and modified specifically for each project. READ MORE

  5. 5. Cost-Effective Pathways for Gasification-Based Production of Biofuels

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Johan Ahlström; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; power-to-gas; Biorefinery; SNG; heat integration; bark; Gasification; sawmill; hydrogen;

    Abstract : A considerable number of studies indicate that biomethane produced through gasification of lignocellulosic biomass could contribute significantly to greenhouse gas emissions reduction in the transport sector. However, the production costs are high compared to fossil-based alternatives, which has limited deployment of the technology. READ MORE
