Postdoc: Validating a Digital Twin for Evaluating Emission Reduction Strategies for Inland Shipping

Job description

The postdoctoral research is part of the NWO project “PAving THe way towards Zero-Emission and RObust inland shipping (PATH2ZERO)”, which aims to develop breakthrough action perspectives and sustainable business models for all parties in the inland shipping chain, contributing to the transition to emission-free inland shipping. The main objective of the project is the evaluation of zero-emission strategies, the effectiveness of policies and technologies, and the assessment of the consequences of their implementation on the inland shipping system.

One aim of the PATH2ZERO project is to translate research outcomes into practice, so that end users can make better-informed decisions. For this purpose, PATH2ZERO aims to develop a digital twin. The main goal of this data-driven virtual representation of the inland waterway transport system is to assess the efficiency of proposed solutions for emissions reduction in inland waterway transport. Three main aspects are regarded as vital components of the digital twin: the individual vessels, fleet and its operations, and the infrastructure.

As these components require a detailed representation within a large-scale transport system, a meso-scale agent-based approach has been selected as a suitable basis for the digital twin. This enables the assessment of potential interventions, ranging from the application of new technologies to individual vessels to policy measures that are implemented for an entire shipping corridor, or various bunker infrastructure strategies in the network. In addition, the impact of the feasible interventions can be evaluated, ranging from the individual ship level and its emissions to the network level and the aggregated emissions in an entire area, or the impact on the logistics chain.

For validating the digital twin, real-world data sources (AIS data, hydrodynamic data, infrastructure data, etc.) will be used in combination with already existing tools for maritime traffic simulation (e.g., OpenTNSim, which is being developed at TU Delft), energy consumption estimates, and emission algorithms. The relevant processes at the individual vessel level can be modelled in detail, and their performance can be tracked in time and space. Corridor scale effects will be simulated by aggregating the results of multiple vessels that together represent the corridor's traffic.

Three regions will be modelled as areas of interest: the Rotterdam – Basel corridor (an open waterway, that is vulnerable to high and low discharge events), the Rotterdam – Antwerp / Gent corridor (a closed waterway that includes various locks and short-sea shipping), and the larger Port of Rotterdam region (a region that includes both sea-going and inland vessels in an area subject to currents and tides).

While the scope of this research focuses on validating a digital twin using operational data from inland vessels, it is expected to involve close collaboration with project stakeholders and researchers within the project. This collaboration will contribute to the quantitative assessment of emission reduction strategies, paving the way toward zero-emission inland shipping.

Job requirements
We are looking for a candidate with an interdisciplinary track record who is able to integrate engineering, environmental, and social science knowledge into a new framework for zero-emission inland shipping. This position requires outstanding skills in modelling and working with big datasets. In addition, the applicants should have:

• PhD diploma in Transportation, Logistics, Civil Engineering, Mechanical Engineering, Maritime Engineering, or any other related field.
• Experience with agent-based modelling is essential.
• Experience with big data analytics, Python, and an affinity for acquiring new skills in this area.
• Ability to collaborate with both scientific and industrial partners.

Postdoc Bipolar Membrane Development for Acid-Base Flow Battery Systems

Job description

Energy storage is an indispensable factor for bridging the electricity consumption with the intermittent renewable energy supply. Electricity grids face significant challenges in balancing economic growth with sustainability targets. Rapid electrification across industrial, transport, commercial, and residential sectors strains existing grid infrastructure, leading to congestion and transmission bottlenecks. These issues limit the integration of renewable energy. Long-duration energy storage (LDES), that provide 8+ hours of storage, can balance intermittent production and demand, thereby stabilizing the grid, reducing reliance on fossil fuels, and ensuring more effective use of renewable energy. TenneT expects 4.9 GW of large-scale battery storage is required in The Netherlands by 2030, while there was only 0.14 GW installed in 2023. Hence, a rapid scale-up of LDES is needed.

In that light, we started a collaborative project, with universities (TU Delft, UTwente, TU/Eindhoven, HAN) and companies (AQUABATTERY, Elestor, Exergy Storage, RWE, Nobian), to develop batteries for long-duration energy storage. Specifically, this postdoc position focuses on acid-base flow batteries, and more specifically the stack engineering in this system. Acid-base flow batteries are based on dissociating water into acid and base during charging, using bipolar membranes, and recombining acid and base in this membrane to retrieve electrical energy.

We’re looking for an excellent postdoc, with strong membrane development skills, to study development of bipolar membranes for acid-base flow batteries. In close collaboration with researchers at TU/Eindhoven and AQUABATTERY, we'll develop new bipolar membranes with high water dissociation efficiency, low resistance, and high selectivity. You'll develop new materials and new configurations to improve the membrane performance, and you'll analyze the directions for improvement. You'll also study possible other membrane-related aspects and other applications for the same materials. Part of the job is to educate students in courses related to the research.

In case you're interested in working with flow batteries for long-duration energy storage, and not particularly in bipolar membrane development, please feel free to also look at other vacancies posted at the same time in the framework of the REDOX BLEND project.

Job requirements
We’re looking for a candidate with:

• A PhD degree, in chemical engineering or applied chemistry
• Proven experience in working with bipolar membranes
• Proven experience in nanostructures and catalytic membranes
• An excellent publication record
• Pro-active and creative mind-set
• Fluent in English. Speaking Dutch is a plus
• Starting date October 2026
