Barriers and opportunities for the deployment of CO₂ electrolysis in net-zero emissions energy systems

As energy systems across the globe transition toward net-zero emissions, the decarbonization of hard-to-decarbonize sectors, e.g., industry and transportation, is becoming more crucial. Renewable power-driven carbon dioxide (CO₂) electrolysis has the potential to facilitate this transition by (1) substituting carbon-intensive...

Submodeling Method-Based Thermal Investigation of the Battery Energy Storage System Integrated in a 450 kW EV Charger

The electric vehicle (EV) market is expanding rapidly. However, the main barriers to EV adoption are high vehicle costs, range issues, and charging infrastructure. Meanwhile, energy storage systems (ESS) appear as a promising solution to preventing grid overload during charging and reducing infrastructure costs. In this paper, the integration of...

Opto-electronic feedback control of membrane potential for real-time control of action potentials

To unlock new research possibilities by acquiring control of action potential (AP) morphologies in excitable cells, we developed an opto-electronic feedback loop-based system integrating cellular electrophysiology, real-time computing, and optogenetic approaches and applied it to monolayers of heart muscle cells. This allowed accurate...

Preliminary sizing methodologies for regional aircraft with liquid hydrogen fuel and SOFC-GT-Battery hybrid-electric powertrains

Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...

Dynamic Modelling of A Rolling Piston Compressor Including A Packed-Bed Drying System

To produce an alternative fuel like Methanol from scratch, on a miniature scale- the reactants CO2 and H2O are sourced locally. Zero Emission Fuels B.V. (ZEF) does this by collecting carbon dioxide from the air, via carbon capture techniques and compressing it to high pressure of 55bars. As a consequence of humidity inside the captured CO2,...

The role of gas infrastructure for integrating offshore wind in the North Sea region: Analysing different energy visions in the North Sea region

This research explores the different envisioned roles of gas infrastructure for integrating offshore wind into the energy system of the North Sea Region (NSR). In this research, the NSR is defined as consisting of the Netherlands, Germany, Belgium, Norway, Denmark and the United Kingdom. The NSR is characterized by the increasing use of their...

The Impact of System Integration on System Costs of a Neighborhood Energy and Water System

The fossil-based energy system is transitioning towards a renewable energy system. One important aspect is the spatial and temporal mismatch between intermitted supply and continuous demand. To ensure a reliable and affordable energy system, we propose an integrated system approach that integrates electricity production, mobility, heating of...

From Silicon toward Silicon Carbide Smart Integrated Sensors

Comprehensive Business Modelling: Hydrogen and its Integration in the Dutch Energy System: Business modelling from the perspective of a public-private partnership for the case of ‘H-vision’, a project for the implementation of blue hydrogen in the Port of Rotterdam

The goal of this thesis is to determine the effects of integrating blue hydrogen into the Dutch energy system. A new framework is presented to assess several different designs for the business model, infrastructure, and market. This framework is applied to the case of the H-vision project. Three business models are tested against three energy...

Machine learning in Maritime Technology: Energy storage size reduction using load forecasting for pipelaying vessels

During dynamic positioning operations, vessels typically run with an extra generator (spinning reserve) for redundancy purposes such that no single fault will cause the vessel to lose its position or heading. As a result, all other engines on the grid share the load equally to ensure that if a failure were to occur, the remaining healthy...

A single-chip micro-opto-electro-mechanical system for optical coherence tomography imaging

How Renewable Energy is Reshaping Europe’s Electricity Market Design

We present a systematic review of the challenges to the regulation of electricity markets that are posed by the integration of variable renewable energy sources. System integration is the key to developing the required flexibility, because flexibility options exist at all system levels and within the competitive as well as in the regulated ...

Realizing Service Migration in Industry - Lessons Learned

In this paper, we present two descriptive case studies covering the re-engineering and further evolution of adopting service oriented architecture (SOA) in industry. The first case was carried out for a company in the transport sector with an application portfolio of over 700 systems. The second case study was conducted for an organization in...

Successful strategies for ESD: Sailing on the winds of change

In a series of eight experiments on ESD (education for sustainable development) between 1991 and 2010, a range of different strategies were applied, e.g. the development of a new study program dedicated to sustainable technology, the integration of SD (sustainable development) in existing programs, the development of an ESD assessment tool ...

The electrical, thermal and spatial integration of a converter in a power electronic module

This thesis is concerned with the design and implementation of a power electronic system (14/42V DC/DC converter) that is implemented in the automotive environment, specifically the engine compartment. The power electronic system must have a high power density while operating in a high temperature environment. Power electronic modules are...
