  2. 21. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping

    Author : Fayas Malik Kanchiralla; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impact; life cycle costing; battery electric; fuel cells; electro-fuel; technical feasibility; economic impact; hydrogen; life cycle assessment; carbon capture; marine fuel; engines; ammonia; carbon abatement cost; shipping; methanol;

    Abstract : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. READ MORE

  4. 22. Four carbon oxychemicals from renewable resources

    Author : Adam Marschall Jaros; Christian Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. READ MORE

  5. 23. Catalytic Combustion in Gas Turbines : Experimental Study on Gasified Biomass Utilization

    Author : Arturo Manrique Carrera; Torsten H. Fransson; Gianpiero Groppi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Abstract : Environmental and geopolitical concerns encourage societies towards the utilization of renewable energy sources (RES). Photovoltaic and wind power can produce electricity directly, although their intermittent characteristic negatively affects the security and safety of the energy supply chain; moreover, in order to be viable it is necessary to establish energy storage systems and to find mechanisms to adapt the power distribution grid to larger production variability.

  6. 24. Protoplast isolation from marine macroalgae and application to studies of inorganic carbon utilization

    Author : Mats Björk; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 25. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study

    Author : Chen Yang; Lundqvist Per; Carlos Infante Ferreria; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. READ MORE
