  2. 11. On the Performance of Long-Range Autonomous Underwater Vehicles : Enhancing the Endurance of AUVs

    Author : Clemens Deutsch; Jakob Kuttenkeuler; Roger Berg; Martin Ludvigsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous underwater vehicles; Underwater gliders; Propulsion; Fuel cell; Energy management strategies; Autonom undervattensfarkost; Undervattensglidning; Propulsion; Bränslecell; Energy Management Strategies; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. READ MORE

  4. 12. Materials Reliability in PEM Fuel Cells

    Author : Live Mølmen; Peter Leisner; Ulf Jansson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; PEMFC; Bipolar plate; Catalyst; Electrodeposition; Corrosion; Stainless steel; Accelerated stress tests; bränsleceller; PEM; bipolära plattor; katalysator; elektroplätering; korrosion; accelererad testning;

    Abstract : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. READ MORE

  5. 13. Electrochemical properties of alternative polymer electrolytes in fuel cells

    Author : Annika Carlson; Rakel Lindström; Göran Lindbergh; Carina Lagergren; Mohamed Mamlouk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cell; anion exchange membrane; proton exchange membrane; electrode morphology; hydrogen oxidation reaction; water transport; poly phenylene oxide ; cellulose; bränslecell; anjonledande membran; protonledande membran; elektrodstruktur; vätgasoxidation; vattentransport; poly fenylenoxid ; cellulosa; Chemical Engineering; Kemiteknik;

    Abstract : Fuel cells, using hydrogen as energy carrier, allow chemically‑stored energy to be utilized for many applications, including balancing the electrical grid and the propulsion of vehicles. To make the fuel cell technology more accessible and promote a sustainable energy society, this thesis focuses on alternative polymer electrolytes, as they can potentially lead to a lower cost and a more environmentally‑friendly fuel cell.

  6. 14. Cost and financing of the sustainability transition of the Swedish road freight transport sector

    Author : Elmira Parviziomran; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

    Abstract : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.
