1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Jonathan Envall; [2023]
   Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

   Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

4. 3. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Kaj Törngren Sato; [2023]
   Keywords : Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

   Abstract : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. READ MORE

5. 4. EV charging approaches in remote regions – Analysis of capacity, cost and logistics

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Farhaan Ahamed; Juan Ordonez Marin; [2023]
   Keywords : Technology and Engineering;

   Abstract : With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. READ MORE

6. 5. A Techno-Economic Case Study of the Implementation of Hydrogen Technology in Connection to a CHP Plant

   University essay from Lunds universitet/Institutionen för energivetenskaper
