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...

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...

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...

Optimisation-based system designs for deep offshore wind farms including power to gas technologies

A large deployment of energy storage solutions will be required by the stochastic and non-controllable nature of most renewable energy sources when planning for higher penetration of renewable electricity into the energy mix. Various solutions have been suggested for dealing with medium- and long-term energy storage. Hydrogen and ammonia are...

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...

Sizing and Control of a Hybrid Ship Propulsion System Using Multi-Objective Double-Layer Optimization

Ship hybridization has received some interests recently in order to achieve the emission target by 2050. However, designing and optimizing a hybrid propulsion system is a complicated problem. Sizing components and optimizing energy management control are coupled with each other. This paper applies a nested double-layer optimization...

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...

Techno-economical Model based Optimal Sizing of PV-Battery Systems for Microgrids

Microgrid with integrated photo-voltaics (PV) and battery storage system (BSS) is a promising technology for future residential applications. Optimally sizing the PV system and BSS can maximise self-sufficiency, grid relief, and at the same time can be cost-effective by exploiting tariff incentives. To that end, this paper presents a...

Residential grid storage technology battles: a multi-criteria analysis using BWM

This article focuses on the battle for dominance between various battery technologies in the residential grid storage market (< 10 KWh) in the context of residential energy systems and the related home energy management systems. We focus on five major battery technologies that are available in the market (lithium-based batteries, lead...
