  1. 1. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mathieu Minaud; [2024]
    Keywords : ;

    Abstract : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. READ MORE

  2. 2. Freight Transport in the Car-Free City : Towards a more sustainable urban freight sector

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Melisa Marta; [2023]
    Keywords : Car-free city; sustainable urban freight transport; urban consolidation center; cargo bicycles;

    Abstract : Freight transport of goods is an indispensable part of everyday life. Without it there would be no delivery of products such as food, water, construction material, technology, furniture, clothes and society, as we know it today, would collapse.  However, there are more and less sustainable ways of transporting goods.

    Author : Hao Liu; [2023]
    Keywords : Technology and Engineering;

    Abstract : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. READ MORE

  5. 5. Inclusion of more sources in a commercial brachytherapy Monte Carlo

    University essay from

    Author : Philip Wiman; Emil Forsberg; Robin Vestling; [2023]
    Keywords : ;

    Abstract : Brachytherapy is a cancer treatment method where a solid radioactive source is placed inside the body in order to target cancer cells with a high dose of radiation while minimizing damage to surrounding healthy tissue. The most common method for treatment planning in brachytherapy is the TG43 formalism where the whole patient geometry is treated as water. READ MORE
