Meaningful Circular Metabolism

The main products of this graduation are a new pattern language to map difficult/technical interventions in spatial tiles, a GIS model for assessing urban metabolism potentials and restrictions and a new approach for applying urban metabolism measurements on neighbourhood level. A personal motivation for me is the relation between the urban...

Local Hydroelectric Energy Storage: A feasibility study about a small scale energy storage system combining hydropower, gravity power, spring power and air pressure

Renewable energy sources, like wind- and solar power, are expected to generate a greater part of the electricity production in the Netherlands each upcoming year. Besides all the advantages, the energy supply of these renewable energy sources fluctuates heavily as they mainly depend on the amount of wind and sun. Therefore, the electricity...

Prevention of pin tract infections in external fixation by an electric current

Pin tract infection is a prevalent complication in treatments with external fixation. This study focused on the external fixation utilized for the knee joint distraction treatment. In a previous study initiated by the UMC Utrecht 85% of the patients got at least one pin tract infection during this treatment. A pin tract infection is caused by...

A scenario analysis of the energy use in the U.S. steel industry: Possibilities for and limitations to energy transition

Much attention is directed towards how to rapidly decarbonise the energy system. Unlike the present energy system based on fossil fuels, an energy system based on renewable energy sources with hydrogen and electricity as energy carriers would be sustainable in terms of CO2 emissions. Whereas in certain sectors (e.g. transport) the opportunities...

Impact of Wind Generation on Electricity Prices in Day Ahead Market

This master thesis aims at understanding the impact of wind on day-ahead-market (DAM) electricity prices using an integrated engineering-economic model. A realistic case study has been implemented, which is Electric Reliability Council of Texas (ERCOT) in Texas, U.S. in the month of August, 2014. To address the main research question of wind ?s...

Creating a pricing mechanism for real-time balancing in sustainable electricity markets

This thesis considers the problem of designing a mechanism that efficiently regulates imbalances on the energy grid. Brokers aggregate supply and demand on the energy market by buying and selling power ahead of time. Mispredictions create discrepancies between supply and demand and need to be resolved. With the increasing usage of sustainable...

A User Friendly Biogas Socket for the BoP: A case study for TNO in Rwanda

This master thesis is carried out for independent research organisation TNO, who initiated the Biogas Socket project in 2008. The Biogas Socket project is part of TNO’s ‘Innovation for Development programme’, wherein high tech development and low-tech innovations contribute to stimulate economic growth and prosperity in BoP countries. This...

Making a living out of the wind: A practical approach for RIWIK to enter the rural MSE market in Kenya

In rural areas in Kenya, only 6% of the rural population has access to electricity. Hence there is a large market for electricity solutions such as solar and wind power. RIWIK is Dutch start-up that produces and sells Small Wind Turbines (SWTs) in Kenya. An SWT can produce enough electricity for one family or business. RIWIK’s business is based...

The Organization of a Cross Border CHP-Alliance: Managing the Cultural Differences

CHP-Belduco is a Combined Heat and Power plant, which was built on the site of Belchem, a chemical company in Flanders, Belgium. The purpose of the plant is to deliver steam and other utilities to the chemical plants on the site. In order to do that efficiently, the combination of heat and electricity is used. The plant is owned and managed by...

Stimulating behaviour change in electricity consumption patterns by using social awareness based incentives in an interface design

This study is performed as part of the project ‘Jouw Energie Moment’, which is initiated by Enexis to support the energy transition that is about the start. This project takes place in the ‘Muziekwijk’ in Zwolle, the Netherlands. If one looks at the future energy supply, the expectation is that both the amount of sustainable electricity and...

Congestion management in the Dutch power sector: A quantitative evaluation of policy options

Due to the introduction of a new grid connection policy, transmission system operator TenneT expects congestion to arise on the Dutch transmission grid in the near future. This new connection policy was introduced by the Ministry of Economic Affairs to abolish the discrimination between existing grid users and new entrants, and should improve...

Congestion management within and between the Dutch and German transmission networks

Electricity is an essential service that can be seen as a utility necessary for modern life. It is typically generated in large scale power plants, and must then be transported through a capital intensive infrastructure known as the transmission grid. It can not be easily stored for later use, which implies that supply and demand of it must be...

Bulk Electricity Sea Transport from Remotely Located Power Plants

Electricity is one of the most utilized energy carriers for energy transmission in the world. In recent years more electricity is generated from renewable energy sources. The main drawback of renewable energy sources is that renewable energy power plants are often connected to certain locations. Sometimes these renewable energy power plants are...
