van Hagen, L.J.A. (author), Petrick, Kristian (author), Wilhelm, Stefan (author), Schmehl, R. (author)A key motivation for airborne wind energy is its potential to reduce the amount of material required for the generation of renewable energy. On the other hand, the materials used for airborne systems’ components are generally linked to higher environmental impacts. This study presents comparative life-cycle analyses for future multi-megawatt...journal article 2023

Joshi, R. (author), Kruijff, Michiel (author), Schmehl, R. (author)In the current auction-based electricity market, the design of utility-scale renewable energy systems has traditionally been driven by the levelised cost of energy (LCoE). However, the market is gradually moving towards a subsidy-free era, which will expose the power plant owners to the fluctuating prices of electricity. This paper presents a...journal article 2023

Reuchlin, S.P.A. (author), Joshi, R. (author), Schmehl, R. (author)The majority of remote locations not connected to the main electricity grid rely on diesel generators to provide electrical power. High fuel transportation costs and significant carbon emissions have motivated the development and installation of hybrid power systems using renewable energy such these locations. Because wind and solar energy is...journal article 2023

Li, M. (author), Jiang, X. (author), Carroll, James (author), Negenborn, R.R. (author)The determination of maintenance strategies is subject to complexity and uncertainty arising from variable offshore wind farm states and inaccuracies in model parameters. The most common method in the existing studies is to adopt an open-loop approach to optimize a maintenance strategy. However, this approach lacks the ability to capture...journal article 2023

Poland, J.A.W. (author), Schmehl, R. (author)Airborne wind energy systems using flexible membrane wings have the advantages of a low weight, small packing volume, high mobility and rapid deployability. This paper investigates the aero-structural deformation of a leading edge inflatable kite for airborne wind energy harvesting. In the first step, a triangular two-plate representation of the...journal article 2023

Vergassola, M. (author), Cabboi, A. (author), van der Male, P. (author), Colomés, Oriol (author)This work aims to develop a low-fidelity model for a lattice support structure for offshore wind applications. The proposed low-fidelity model consists of a sequence of regular Timoshenko beams, each of them characterized by homogenized mechanical and mass properties representative of the single bays of the reference space-frame structure....journal article 2023

Frontera Pericas, Pere (author)Floating offshore wind turbines (FOWTs) have the potential to harness wind resources in deepwater, which is so far prohibitive for conventional approaches. This, however, comes at a cost: the platform’s extra degrees of freedom (DoFs) introduce complex aerodynamic and hydrodynamic behaviours. Therefore, FOWTs must be accurately modeled to reduce...master thesis 2022

Castellino, Francesco (author)One of the main cost drivers of an offshore wind power plant are the support structures of the wind turbines, it is therefore of primary importance to optimize their design. Among the support structures available, the concept most widely adopted is the monopile-based support structure, whose design is often fatigue-driven. Offshore structures...master thesis 2022

Porta i Ko, Agustí (author)Airborne wind energy (AWE) systems benefit from a high lift airfoil to increase the power output, to that end, multi-element airfoils are investigated for AWE applications. This thesis aims to optimize a multi-element airfoil for a rigid AWE kite that operates in a pumping cycle. Since the kite has distinct operational phases, i.e., reel-out and...master thesis 2022

Steggink, Maarten (author)To accommodate the growing demand for renewable energy, installation of new offshore wind energy capacity is increasing in many countries. New projects will be proposed for waters in which floating (sea) ice is a common occurrence in winter. Currently, projects remain limited to regions with mild ice conditions, such as the Southern Baltic Sea,...master thesis 2022

Franz, Kelsey (author)Wind farm interactions with the surrounding airflow leads to a reduction in velocity greater than the linear sum of single turbine inductions and is known as global or upstream blockage. The mechanisms and magnitude of global blockage effect are not yet fully understood. Models to simulate upstream blockage to improve efficiency estimates and...master thesis 2022

Saccone, Cecilia (author)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that using floating turbines allows them to move to deeper waters, reducing visual and environmental impact and allowing footprint...master thesis 2022

van der Spek, Joep (author)Reducing the levelised cost of energy is crucial to accelerating the energy transition. To develop offshore wind solutions in greater water depths, a floating solution is required. The time-domain simulations of these Floating Offshore Wind Turbines (FOWTs) under wind-wave misalignment used in research and industry projects are computationally...master thesis 2022

REPPAS, APOSTOLOS (author)Renewable forms of energy, and especially wind energy, have become an integral part of the energy infrastructure around the globe. However, the constant increase of installed wind capacity has put a strain on the selection of potential onshore locations for wind turbine installation. As a result, the wind industry is focusing on offshore...master thesis 2022

Klop, Casper (author)Offshore wind energy is expected to play a major role in the upcoming energy transition. For long distances to shore, it is preferable to connect the wind farms to land by means of High-Voltage DC (HVDC) cables to reduce losses and costs.
