    Författare :Maria Grahn; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Maria Grahn; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Towards sustainable personal mobility with electric cars and buses

    Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Ödlund; Maria Grahn; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA; Mobility;

    Sammanfattning : The aim of this thesis was to explore if, and then how, electric cars and buses can contribute to sustainable personal mobility. Electric vehicles have increasingly been seen as a potential sustainable solution for the transport sector due to their high energy efficiency, close to zero emissions in the use phase, and the possibility to be powered by electricity from renewable resources.

  7. 5. Power to gas : Bridging renewable electricity to the transport sector

    Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

    Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER
