  1. 1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Merhawi Belai; [2024]
    Keywords : nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Abstract : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. READ MORE

  3. 2. 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
