  1. 21. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

  3. 22. Engaged Employees in Energy Conservation : exploring how to get there

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Linnea Bedoire; Maria Nordling; [2023]
    Keywords : community-based social marketing; pharmaceutical industry; employee engagement; energy conservation; intervention; workplace; norms; pro-environmental behaviors;

    Abstract : Energy consumption is one of the major contributors to greenhouse gas emissions and to climate change. Renewable energy sources are one way of mitigating the problem, but behavioral change and reductions in consumption are also required. READ MORE

  4. 23. Techno-economic analysis and simulation of low temperature district heating networks

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ilia Iarkov; [2023]
    Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

  5. 24. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oskar Sundberg; [2023]
    Keywords : geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Abstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

  6. 25. The Swedish tax rules for electricity production in breach of EU tax law

    University essay from Lunds universitet/Institutionen för handelsrätt

    Author : Ingi Hilmar Sigurdsson; [2023]
    Keywords : EU Law; State aid; de minimis aid; de minimis Regulation; Article 107 TFEU; Article 108 TFEU; energy taxation; renewable energy.; Law and Political Science;

    Abstract : This thesis examines the way in which Sweden opted to set up its taxation on the supply of energy from renewable sources and whether they are in line with EU tax law. Windmills in Sweden are granted a lower-rate tax than other sources of renewable energy production, which is stated to be within the scope of the de minimis Regulation. READ MORE
