Conceptual Design and Performance Analysis of an Expander for the Recovery of Potential Energy Stored in Compressed Hydrogen

In the scope of global decarbonisation, hydrogen has been identified as an essential energy carrier. Not only as an energy storage solution for further electrification in vehicles but also as a primary fuel source in processes that rely on chemical energy which cannot be easily electrified. However, at ambient conditions, hydrogen is also a very...

Validation and analysis of loading models for a multi-megawatt floating offshore two-bladed wind turbine

Offshore wind is a rapidly maturing renewable energy technology and is expected to play a central role in future energy systems. It has the potential to generate more than 420,000 TWh per year worldwide, an amount approximately equal to eighteen times the global electricity demand today. While many of the most abundantly resourceful sites are at...

Weight Estimation of Gas Turbine Engines: Development of a Component-Based Preliminary Engine Design Tool

The need for more efficient aircraft has spawned the conception of a variety of novel engine and aircraft architectures, such as the combined-cycle engine proposed by researchers at Delft University of Technology. To evaluate the potential benefits of these concepts comprehensively, in-depth performance simulations are required. Furthermore,...

Floating Offshore Wind Development Concept: A sustainable O&M approach

This research examines the difference between two major component replacement strategies for the novel floating offshore wind turbines (FOWT), in terms of support vessel CO2eq emission and cost together with FOWT downtime. The first strategy is utilising a crane vessel to replace a component in offshore, this is called the heavy lift maintenance...

A review of gas turbine engine with inter-stage turbine burner

Society is going through transformations at a rate that is unprecedented in human history. One such transformation is the energy transition, which will affect almost every facet of our society. Gas turbine engines are state of the art machines, a backbone of modern society, and used in various applications, right from power generation to...

The design of a sustainable and maintenance friendly wind turbine nacelle for DOT

Conventional offshore wind turbines tend to be difficult to maintain. Maintenance contributes to 25% of the total cost of energy and forms an important phase in the lifecycle of the turbine and has a significant impact on its sustainability. The design resulted from this master thesis is a nacelle for the DOT wind turbine. It creates a working...
