Applying Mixed-Integer Quadratically Constrained Programming to Reduce Fuel Cell Degradation Onboard a Hybrid Ship

New methods of ship propulsion are required to meet the targets for reducing global emissions of greenhouse gases. Hydrogen-powered fuel cells can be used to greatly reduce emissions, facilitating renewable shipping. Fuel cell durability is recognised as a large barrier to widespread fuel cell application. The goal of this graduation project is...

Making the Production of Green Hydrogen by Electrolyser Economically Viable

Green hydrogen plays an important role in the energy transition. It can function as a storage medium, as well as a replacement for fossil fuels in transport or high-temperature heat processes. However, the economic feasibility of electrolysers has proved to be a problem. Even though a lot of research has been done to the electrolysis technology,...

Multi-Horizon Prediction of Power Consumption during Dynamic Positioning Operations: Physical, Data-Driven and Hybrid Model Approaches

A significant decrease in greenhouse gas emissions can be achieved by including a prediction of future power consumption in the control of ships’ power plants during transits. Moreover, including a prediction of power consumption in the Energy Management System (EMS) during Dynamic Positioning (DP) operations can also contribute to a reduction...

A real-time energy management system for a grid-connected solar park using an electrolyser in the Netherlands: Optimizing to maximize the revenue

This paper describes a real-time energy management system developed for a solar park in the Netherlands using an alkaline electrolyser. The optimization problem is split into a two-step optimization, taking into account the specifications of the electrolyser and allowing the electrolyser to respond to changes in the imbalance market. The first...

To Store or Not to Store: A Q-Methodological Study into the Influence of Perceived Needs and Factors on the Implementation of Electrical Storage Applications in the Dutch Power Grid

Modern society is highly dependent on the reliable supply of affordable electricity. To ensure a sustainable future, this energy should be derived from renewable generation systems. The intermittent output of such systems makes it hard to maintain the so-called grid balance, which can lead to the malfunctioning of the current power grid. Adding...

Hierarchical MPC for Energy Management of Multi-Energy Systems: Case Study Based on a Power-to-X Concept

All over Europe, the expansion of renewable energy sources is quickly proceeding, fueled by environmental and political motives. The power generated by renewables is heavily subject to the intermittency of the source, e.g. the availability of wind or solar irradiance. Consequently, electrical grids that rely on renewable sources alternate...
