  1. 1. Environmental Assessment and Strategic Technology Choice: The Case of Renewable Transport Fuels

    Author : Karl Hillman; Ken Green; Björn Sandén; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental assessment; renewable fuels; life cycle assessment LCA ; strategic technology choice; socio-technical change;

    Abstract : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

  2. 2. Global energy transitions : Renewable energy technology and non-renewable resources

    Author : Simon Davidsson; Mikael Höök; Kjell Aleklett; Björn Sandén; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. READ MORE

  3. 3. Power to gas : Bridging renewable electricity to the transport sector

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

    Abstract : 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. READ MORE

  4. 4. Energy systems studied of biogas : Generation aspects of renewable vehicle fuels in the transport system

    Author : Mimmi Magnusson; Per Alvfors; Umberto Desideri; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Anaerobic digestion; biogas; biomass; energy system; first-generation biofuels; renewable vehicle fuels; second-generation biofuels; supply- and demand-side measures; third-generation biofuels; transport system;

    Abstract : The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. READ MORE

  5. 5. Renewable and Scalable Energy Storage Materials Derived from Quinones in Biomass

    Author : Lianlian Liu; Olle Inganäs; Niclas Solin; Daniel Brandell; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; renewable; scalable; quinones; energy storage;

    Abstract : Currently there is an urgent need to reduce the use of fossil fuels, and efficient sustainable energy harvesters from sun and wind have been developed and are widely used for electricity generation. Storage of electrical energy is accordingly necessary to accommodate the time varying supply of wind and solar electricity. READ MORE
