  1. 1. Azelio’s Thermal Battery for Combined Heat and Power : A Thermo-economic and Market Research Study

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Martin Lantz; [2020]
    Nyckelord :Carnot battery systems; thermal energy storage; techno economic analysis; market review;

    Sammanfattning : The objective of this thesis was to assess the market opportunities for two novel Carnot battery system solutions, one supplying power and low temperature heat as well as a system supplying medium temperature heat exclusively. To fulfill the objective, a methodology was developed and implemented to investigate the market potential, further two techno-economic models were developed and utilized to investigate the performance of such Carnot battery solutions.

    Sammanfattning : Energy systems with a high portion of renewable energy from wind and solar power can suffer from fluctuations in production due to weak winds or cloudy weather, which may affect the electricity price. When producing heat and power in a combined heat and power plant, an additional heat storage tank can be used to store the heat surplus which is obtained when the power production is high, and the heat demand is low.

    Sammanfattning : Den stora användningen av fossil energi i världen är en av orsakerna till de höga utsläppen av koldioxid som förstärker växthuseffekten. För att minska människans klimatpåverkan bör därför mer förnyelsebar energi användas. EU har därför som mål att minska utsläppen av koldioxid med 40 % till år 2030. LÄS MER

  4. 4. Pilot Project Study for Industrial Surplus Heat Transportation

    Master-uppsats, KTH/Energiteknik

    Författare :Kristoffer Pettersson; [2016]
    Nyckelord :;

    Sammanfattning : Primary energy use in Sweden today can to a large extent be traced to manufacturing industries. In parallel, improved energy efficiency is a goal set out by Swedish authorities and the EU. One way to improve efficiency in the industry is to harvest the excess energy in form of heat that is currently going to waste in the various processes. LÄS MER

  5. 5. Konsekvenser av tredjepartstillträde för en lokal fjärrvärmemarknad

    Master-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Mattias Wesslau; Anders Palm; [2009]
    Nyckelord :Industriell restvärme; Naturligt monopol; Fjärrvärme; Industrial surplus heat; Natural monopoly; Third Party Access; Tredjepartstillträde; District heating; TPA; Management of enterprises; Företagsledning; management; Business and Economics;

    Sammanfattning : Problem: There are strong forces from for instance politicians, who want to allow third party access to the district heating market, as has already been done in the electricity and gas markets. But what would be the consequences of a third party access to the district heating market? Will it create a competitive market, and will it be able to put any pressure on the prices? What will be the consequences for the current monopoly holder? Purpose: The purpose is to investigate the impact of allowing third party access to a local district heating market Methods: The questions raised have been answered with a case study at the district heating system in Helsingborg.
