  2. 11. Life Cycle Assessment of Present and Future Marine Fuels

    Author : Selma Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

    Abstract : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

  4. 12. Methanation of biosyngas in a fluidized bed reactor

    Author : Martin Seemann; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE

  5. 13. Exploiting cross-level linkages to steer the bioenergy transition

    Author : Francis X Johnson; Semida Silveira; Geert Verbong; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy transition; modern bioenergy; traditional biomass; cross-level linkages; institutional design; regional development; alternative fuels; Energy Technology; Energiteknik;

    Abstract : This thesis develops the notion of the bioenergy transition as the long-term transformation of biomass from a local resource into a global commodity. An historical assessment is combined with interdisciplinary analysis that focuses especially on liquid biofuels and highlights the environmentally innovative case of bioethanol. READ MORE

  6. 14. Utilization of local bioresources for transport fuels - System analysis for decision support

    Author : Muhammad Arfan; Ola Eriksson; Jonas Ammenberg; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; local bioresources; transportation fuels; LCA; LCC; geography of transitions; Systemanalys; Lokala resurser; drivmedel; LCA; LCC; geografi och om-ställning;

    Abstract : This thesis presents a comprehensive system analysis of the utilization of biowaste and forest industry residues to produce transportation fuels. It explores various aspects such as the constraints to the production system’s value chain development, the utilization of the geographical proximity of biofuel technology innovation system components, environmental impacts, and economic costs.

  7. 15. Advanced fuels for thermal spectrum reactors

    Author : Jitka Zakova; Janne Wallenius; Jan-Leen Kloosterman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR; transmutation; thorium; Pu; MA; Am; Cm; AHTR; thermal; reactor; neutron;

    Abstract : The advanced fuels investigated in this thesis comprise fuels non− conventional in their design/form (TRISO), their composition (high content of plutonium and minor actinides) or their use in a reactor type, in which they have not been used before (e.g. nitride fuel in BWR). READ MORE
