Wind farms experience significant efficiency losses due to the aerodynamic interaction between turbines. A possible control technique to reduce these losses to a minimum is yaw-based wake steering. This thesis investigates the feasibility of this technique by calibrating a surrogate model called the FLOw Redirection and Induction in Steady-state...

A method is developed to automatically analyze over 200000 images of a single mature tree. This method is assessed and applied to a tree located at Risø in Roskilde, Denmark, next to two meteorological masts. Image aspects such as the surface area and the center of area are extracted from the images and they are related to the wind statistics....

With the advent of the sustainable energy transition, the deployment of renewable energy sources is rapidly growing. One of the main problems for sustainable systems like wind and polar power is the fluctuating and intermittent behaviour of these sources. In order to make these systems more reliable energy storage is needed to compliment these...

Essential service systems, such as energy provision and wastewater treatment, are important elements within spatial planning as they cater the most fundamental needs of the built environment. The recent rise in decentralized or local systems compared to the common centralized approach have left spatial planners with a dilemma: on which scale...

The island of Bonaire is planning multiple sustainable transitions in the water,<br/>energy and food systems in response to numerous challenges, such as increas-<br/>ing population pressure, rising sea levels, environmental damage, high consumer<br/>prices and import dependency. The water-energy-food nexus is a relatively novel<br/>concept that...

Local emission of especially particulate matter (PM) and nitrogen oxide (NOx) are haz- ardous for people living in close proximity. The municipality of Rotterdam can not yet comply with national regulation regarding N Ox and the current levels of N Ox pose a health risk for society (Gemeente Rotterdam). The Port of Rotterdam and local government...

The fracture energy for hardwood was modeled using finite element modeling (FEM) software DIANA. The results of the model was compared to the fracture energy experimental research performed by Boerenveen (2019). The fracture energy results obtained by the model are similar to the results obtained from the experimental research. An model fracture...

This thesis investigates the potential of a semi-passive trailing-edge flap on a large conceptual wind turbine. The mechanism passively reacts to blade and tower accelerations by changing the airfoil camber, opposing the dynamic loads on the turbine. An active element is present, which influences the mean of the flap oscillation. First, a low...

The building sector uses 40% of the primary energy worldwide. Energy demand in a non-residential existing building is rising due to higher comfort conditions, population growth and the enhancement of the building services. On the other hand, renewable energy technologies are every time more accessible for the built environment, especially the...

The concept of Venturedam was developed to solve societal challenges in India by nurturing the strength of the innovations made in the Netherlands. For Dutch startups to expand to a new market like India that has a considerable difference in the context, it is first required to redefine the value proposition and the business model specific to...

Nitrogen (N) removal is one of the key tasks for every wastewater treatment plant under the growing pressure of environmental protection. Prevailing applied N treatment technologies are mostly energy-intensive. This dilemma triggers a rethinking of the way to approach N management. “N2kWh-From pollutant to power” is a project that aims at...

Sustainability is becoming more important in numerous industries, including healthcare. Action to achieve sustainability is undertaken by various means, such as the Green Deal Healthcare. Several tools exist that can assess the environmental impact of a certain industry or company, but no tools exist that aid in actively lowering this...

The increase in the share of renewable energy sources in the Dutch energy mix, requires an increase in flexibility from the power consumers and producers. A key issue in the availability of wind and solar power that it is independent of the power demand. Fortunately, the liberalised power market provides a financial incentive to increase both...

In today’s industry ammonia is produced on a large scale, and is used in the production of fertilisers, cleaning products and much more. Eventually the ammonia enters our wastewater, either directly or through urine. This is then removed with conventional nitrifying-denitrifying treatment or with Anammox. That process consumes energy and does...

In the search for new forms of renewable energy production, an interesting option is to make use of the energy stored in the ocean in tropical areas. The sun heats up the surface water in these areas to a point it is feasible to generate electricity, using the temperature difference between the hot surface water and the cold ocean water at...

Accurate Annual Energy Yield (AEY) predictions can mean important savings due to optimization of energy generation for both particular and utility scale PV systems. <br/>However, currently available commercial models fall short to faithfully reproduce complex designs, specially involving bifacial modules, where albedo gains are relevant. <br/...

Population growth, meat-focused diets and emerging industries are increasing stress on water, energy and food (hereafter: WEF) supply around the globe. As stress on the resources rises, the interdependencies between the sectors become more apparent and often lead to unforeseen chain reactions. An example of which is: a drought leads to...

In this research the role of thick flexible soles in energy-efficient humanoid walking is analyzed. It is<br/>hypothesized that, the addition of underactuated degrees of freedom under the foot gives the robot<br/>the potential to execute a pseudo-passive walking motion 1, which yields a decrease in ankle torque<br/>and energy expenditure....

Technologies used in the energy sector, and many other sectors, are too complex for innovation by a single actor. Many influences from different types of actors are required to advance the technology, creating a collective innovation process. However, without the right accountability structures between different types of actors, unfavourable...

Long before the existence of today’s computer, information and communication technologies, the design of current energy grids has been set. Nowadays, ‘conventional’ energy grids – including electricity, gas and thermal grids – are being transformed into smart grids, which consist of various technological components such as smart meters, energy...
