Tidal Wave Energy Converter


M. Kloet

Feasibility study of a device that harvests electricity from the vertical motion of pontoons in tidal waves. The study includes an overall look into tidal prediction through laser satellite altimetry and converts the ocean based data of these models into near shore approximations.

Analysis of external influences on an OTEC cycle


V. Gudjónsdóttir

This thesis project is about the effects of ocean temperature variations for a fixed design of the OTEC thermodynamic cycle. These effects are analysed for three different working fluids, pure ammonia, ammonia - water mixture and R32 - R134a mixture. An off design model is implemented in MATLAB to analyse the effects. Experiments were performed with pure ammonia in an OTEC experimental set up to validate the model.

System sensitivity and cold water pipe analysis of a 10MW offshore OTEC plant

B.J. Kleute

The first part of this study is a system sensitivity analysis of a 10MW offshore OTEC plant. The impact of nine design variables on the system performance is identified by applying a thermodynamic and hydraulic model. The results show the system is mainly sensitive to fluctuations in seawater temperature difference, turbine and generator efficiency, seawater pump efficiency and seawater pressure drop. Based on these results, a number of preliminary boundary conditions for the offshore equipment are defined.

The second part of this study is a design analysis focused on the cold water pipe connected to a 10MW offshore OTEC plant. Four different pipe configurations are studied in extreme conditions, based on a potential project site near Curacao.

Techno-economic optimization of Organic Rankine Cycles using working fluid mixtures for 10 to 25 MW OTEC power plants

J.A. Kirkenier

Driving down the cost of OTEC electricity generation is seen as one of the major challenges of this technology. By creating a techno-economic power cycle optimization tool capable of using working fluid mixtures, their potential in OTEC power plants is investigated. The optimization results show that using mixtures can significantly improve the power cycle performance and reduce the cost of electricity production by more than 40%, making it an economically attractive alternative to fossil fuel based power in tropical regions.

This thesis projects analyses a desalination method applying a direct contact condensation process. It makes use of the relative high humidity air in the tropics and condenses it against a cooled fresh water loop in a packed bed column. The cold seawater is used in an external heat exchanger to cool the fresh water loop. Out comes fresh water and cold dry air without the need of energy intensive equipment.

Tidal energy resources assessment in Indonesia: a case study in Alas Strait

N.S. Aziz


This study assesses tidal energy resources in Indonesia. A case study in Alas Strait is selected among many prospective sites considering its relative shallow depth, high current velocity, and location which far from major shipping line. Princeton Ocean Model (POM) is used to model the flow pattern in the site. It uses the bathymetric map to represent the depth and applies tidal elevation in open boundary condition as generating force. The result from POM is then used to quantify the extractable energy resources using farm method.

Feasibility of a power plant: blue energy in the Dutch Delta

R.W. Quak


In this study the main focus lies on the hydraulic aspects of Blue energy. The study showed that in the Dutch Delta five locations exist where Blue energy might be feasible. The Botlek area of the Port of Rotterdam, has been chosen to deepen out. For this location the fresh water availability has been determined with a statistical analysis. Aspects like the changing river regime due to climate changes and salt intrusion into the Delta area have been taken into account. A number of hydraulic simulations (Delft3D, Maasvlakte II Model) have been done in order to determine the maximum salt water flow, and the occurring salinities.

Linear generator systems for wave energy conversion

H. Polinder, et al.


The objective of this paper is to review linear generator systems for wave energy conversion and the research issues related to this. The paper starts with a short review of wave energy conversion, indicating that the different wave energy conversion systems that have been presented in literature have very different generator systems. Next, a few state-of-the-art linear generator systems are discussed, such as the linear generator of the Archimedes Wave Swing (AWS) and the linear generator developed in Uppsala. Subsequently, some remaining problems and possible solutions that need further research are listed. The paper concludes with some sensible directions for further research, such as investigating an increase of the speed of the linear motion of the wave energy converter, investigating other generator types with higher force densities and possibly better efficiencies (for example, transverse flux permanent magnet machines) and investigating generator constructions that result in cheaper generators
