The article discusses a research project in Delft that aims to explore the potential of hydrogen in achieving climate neutrality in hard-to-decarbonize sectors. The current challenges in producing hydrogen through water electrolysis, such as high costs and low efficiencies, are highlighted as barriers to widespread adoption. The project focuses on investigating the interplay between electrolyzer technology design, integration concepts, revenue streams, and flexibility requirements to align with renewable energy sources. Researchers will develop equilibrium models describing interconnected electricity and hydrogen markets, utilizing data-driven approaches to enhance market realism and assess uncertainties. The WinHy project at TU Delft, funded by NWO, involves consortium partners like Repsol and Sunfire in developing advanced electrolyzer technologies and integration concepts. The postdoctoral position offers a unique opportunity to work on electrolyzer asset interaction with the energy system, contributing to technology advancements and economic integration. The ideal candidate should hold a PhD in science, engineering, or economics, possess strong analytical skills, and have prior research experience in energy system modeling or electrolysis-based plant assessment. Proficiency in English is required, with programming skills in Julia, Python, or similar languages considered a bonus. The article also outlines the salary benefits, which are in accordance with the Collective Labour Agreement for Dutch Universities. Employees can expect a salary increase and additional benefits, including health insurance discounts. International applicants can benefit from the Coming to Delft Service, which assists in relocation and offers a Dual Career Programme for partners. Overall, the project provides an exciting opportunity for researchers to contribute to the advancement of hydrogen technology and its role in achieving climate goals.
