Enhancing Greenhouse Gas Emission Performance of Offshore Installation Vessels through Swappable Energy Containers

This master’s thesis explores an alternative approach to enhance the emission performance and energy efficiency of offshore installation vessels without expensive retrofits. The concept involves employing swappable energy containers, currently used for inland cargo and tug vessels, for offshore installation vessels. These containers are filled...

A Health-Aware Control Strategy for Enhanced Performance and Extended Hybrid Powertrain Lifecycle: A benchmark of different cost functions

The urgent need for marine transportation to reduce CO2 emissions has led to considering alternative energy and storage sources. The resulting increase in the complexity of powerplant architectures led to the development of advanced control strategies to achieve energy savings. At the same time, the health status of components has been often...

Experimentally observing discharge characteristics of Si-air batteries: Using KOH and BMPyr[NTf2] as electrolytes

An increasing penetration of renewable energy sources in the global energy market necessitates an increasing amount of energy storage. Batteries are an excellent source of short term storage, used in vehicles, home storage and mobile applications. However modern technologies such as Li-ion batteries face resource scarcity and hence introduce...

Development of a roadmap to a net-zero fleet: A technical and financial evaluation

The maritime sector plays an important role in energy transition because offshore vessels are used for building offshore renewables but also have high emissions. The European Union (EU) has determined that from 2025 the maritime sector must pay per ton of CO2 emission. Heerema Marine Contractors (HMC) is an essential player in the maritime...

Load Cycle Assessment for Maritime Batteries: with Diverse Operational Profile

Increasing emissions have led to the search for alternate power systems to provide energy for maritime applications. The recent drop in battery prices (over 200 % in the last ten years) has made battery energy storage one of the practical alternatives for fossil fuels to curb emissions and reduce the carbon footprint of the maritime sector. The...

Technical and economical feasibility of zero-emission walk to work vessels

Urgent action is needed to decrease maritime emissions. The renewable wind energy sector must also decrease its life cycle greenhouse gas (GHG) emissions. Total GHG emissions from offshore wind turbines are approximately 120% more compared to onshore wind turbines. Moreover, it is estimated that Walk to Work (W2W) vessels are responsible for 3.3...

Ion-Conduction in Solid-State Electrolytes: Investigating the fundamental conduction mechanism in Na3PnS4 (Pn = P, As, Sb) through computation and experiment

Recent studies on various solid-state electrolytes showed that while improvements to the ionic conductivity are progressing swiftly, the understanding of the fundamental conduction mechanism is still lagging behind. We attempt to improve this understanding by providing a more complete overview of how different static (structural) and dynamic ...

Feasibility study of novel seasonal energy storage technologies for residential systems

The growing global energy demand and correlated rise in carbon emissions is forcing us to increase the use of renewable sources. The residential sector represents a large part of the total energy consumption, and European governments are investing in distributed PV to increase the renewable share in this sector. However, on top of the solar...

Choosing a sustainable, economical energy supply system, considering all operational variables of an autonomous submarine dredger: A study as part of the development of the ALERD, which will serve as sustainable coastal maintenance in the service of The Netherlands

The Autonomous Low Energy Replenishment Dredger (ALERD) strives to revolutionize the dredging world. The ALERD operates autonomously underwater, which saves energy during the dredging process and transit. Autonomous underwater operation drives the need of alternative energy facilities. However, due to the energy savings of dredging, alternative...

Batteries and energy arbitrage: A techno-economic analysis of electricity arbitrage opportunities for utility-scale battery energy storage in the Netherlands

As the variable renewable energy share keep on increasing throughout the energy transition, power systems require more and different flexibility measures. Battery energy storage can provide these essential services that enable the energy system to carbonise and transform on short time scales. Energy arbitrage, the trading of electricity on the...

Linking Energy and Logistics: Modelling a Network of Decentralised Batteries: The case study of an Electric Waterbus in Rotterdam

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 Hybrid Power Plant: Optimal design and operation of battery energy storage as an addition to onshore wind farms in the Netherlands

In the Netherlands, wind power has the highest potential for future development compared to alternatives such as solar PV and biomass. The intermittent nature of the wind power resource calls for novel approaches to supply and demand management, as well as power quality assurance. Energy storage technologies allow for the separation between...
