Analytical Studies of the Influence of Regional Groundwater Flow by on the Performance of Borehole Heat Exchangers

This paper presents a new analytical solution for the influence of regional groundwater flow on the performance of borehole heat exchangers. The solution concerns a vertical borehole. The transient thermal response for the fundamental case of a step-change in heat injection rate is given. The solution is remarkably simple and the formulas quite handy considering the complexity of the convective-di

Greening the grid of Indonesia - Second life application for Lithium-Ion Electric Vehicle batteries in Indonesia’s Energy System

Som ett resultat av ökad efterfrågan på elektricitet från urban elektrifiering, den växande ekonomin och global uppvärmning står Indonesien inför stora utmaningar. För att lyckas med hållbar storskalig elektrifiering krävs stora mängder litiumjonbatterier som kan balansera elnätet. Den ökande efterfrågan på dessa har lett till brist på batterimineraler vilket försvårar situationen för landet. Sa

Arbitrage - How to monetize an intermittent market

This thesis tries to answer the question of how to properly trade on an intermittent market using a theoretical storage and estimates attainable profit of such a setup. This have been done through evaluating different storage alternatives, analyzing market trends, investigating associated costs for the operation and simulating possible outcomes. Trading with certain rules, an algorithm has been de

Systematisk sammanställning av större geoenergianläggningar i Sverige

En sammanställning av större geoenergianläggningar i Sverige har i samband med detta arbete gjorts. Arton anläggningar med bergvärme, borrhålslager, högtemperaturlager samt akfiverlager ingår i denna. Utifrån information om dessa anläggningars drift har rekommendationer för mätpunkter getts för att bättre säkra mätning och driftuppföljning. Geoenergi är Sveriges tredje största förnybara energikällShallow geothermal energy is the third biggest renewable source of energy in Sweden. Low-temperature energy stored in the ground and groundwater is collected by a ground heat exchanger with circulating brine and a ground source heat pump, GSHP. It is possible to extract both heating energy and cooling energy in these systems; in the winter the earth is utilised as a heat source, and in the summer

Is the fire performance of phase change materials a significant barrier to implementation in building applications?

This paper examines the reaction-to-fire behaviour of building materials containing phase change materials by predicting their fire classification according to the European reaction-to-fire classification system (Euroclasses). While various building materials containing PCMs exist today, their application in buildings has been somewhat limited due to the fire behaviour of these building materials.

Energy Storage for Voltage Control in LV Grids

Batterier möjliggör mer solel än elnätet tidigare klarat av En ökad andel solenergi i elnätet ställer nya tuffa krav på det befintliga nätet. I det här examensarbetet har möjligheten att undvika nätförstärkning genom att istället installera batterier på väl valda platser i nätet undersökts. Med hjälp av lösningen kan mer solel än nätet tidigare klarat av installeras. Historiskt sett har el produ

Energy flows and potential energy development strategies in RoRo ports: A study based on the Port of Trelleborg

The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. The current energy flows directly concerning the port are for the most part elect

Battery Energy Storage Systems as an alternative to gas turbines for the fast active disturbance reserve

Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. Balancing functions that stabilise the grid are referred to as \textit{ancillary services}, which in Sweden include th
