Doctoral researcher in hydrogen production via metal redox cycles

Are you interested in experimental research and dynamic process modelling in hydrogen production? The Industrial Energy Systems Laboratory at LUT University is seeking a doctoral researcher to develop and analyse pilot-scale data and modelling approaches for metal redox cycle-based hydrogen systems. This role combines experimental work with advanced process modelling and will be a part of the EU-funded HELIA project. You will join an active research group known for its diverse expertise in energy systems. You will work in pilot- and laboratory-scale facilities using advanced process simulation tools and focusing on fluidised bed systems, hydrogen storage, and industrial decarbonisation. About the position You will conduct experimental and modelling research on hydrogen storage and transport using metal redox cycles. The position emphasises hands-on work in a 100 kW pilot-scale experimental facility. Your responsibilities include planning, executing, and analysing laboratory- and pilot-scale experiments related to cyclic oxidation and reduction of metals for hydrogen production and storage. You will also contribute to system performance optimisation and the integration of experimental work with modelling and simulation. In addition to experimental work, you will develop dynamic process models using APROS to support system analysis, the interpretation of experimental results, and the evaluation of different operating concepts. The work also involves studying the potential reuse of decommissioned circulating fluidised bed (CFB) boilers for redox-based hydrogen applications. You will analyse and document research results, contribute to scientific publications, and disseminate findings through conference presentations and consortium meetings. The position involves active participation in national and international research projects in close collaboration with the research team and requires some travel. What we expect from you You have a masters degree in energy technology, chemical engineering, process engineering, or another closely related field, and the ability and motivation to complete your doctoral studies within the normative duration of the degree. You are genuinely interested in experimental research, process modelling, and working with laboratory and pilotscale equipment. Previous experience in these areas is considered an advantage. A solid understanding of thermodynamics, fluidised bed reactors, high-temperature processes, and reaction engineering will help you succeed in this role. You must be able to work safely with hightemperature and pressurised systems, follow structured procedures, and document your work carefully. You should be fluent in written and spoken English, as the role involves scientific writing and communication with the international research community. Finnish skills are an advantage. We are looking for someone who can work independently and communicate and collaborate effectively in an international research environment. You should also be comfortable using standard office and research-related digital tools efficiently. Whether you are a recent graduate or already have some relevant experience, what matters most is your strong motivation and commitment to high-quality research. Junior researchers need to obtain the right to complete doctoral studies at LUT within the first three months of their employment relationship. What we offer The position offers an opportunity to develop strong expertise in experimental and modelling research, contribute to ongoing research projects, and work in a supportive and experienced research team. This full-time position is based in Lappeenranta and requires regular on-site presence with a possibility for occasional remote work. Employment will start with a one-year term (including a six-month trial period) and may be extended by up to three years, depending on the progress of your studies and research. The start date is 1 September 2026 but remains negotiable. The hours are flexible and support work-life balance. The position follows a system of 1,612 annual working hours in accordance with the collective agreement for Finnish universities. The salary is based on the Finnish university pay systems scale for teaching and research staff (requirement level 2). The starting salary is approximately EUR 3,060 per month, depending on experience and qualifications. Interested? Please submit your application through the link below by 31 May 2026 at 23:59 (Finnish local time, UTC+3). Fill out the online application form and attach the following documents in English and in PDF format: - A motivation letter: a separate document describing your motivation as a researcher and past achievements (max. 1 page, A4) - A curriculum vitae (CV) - Scanned copies of your original bachelors and masters degree certificates and transcripts of records; if the original documents are not in English or Finnish, each document must be accompanied by an official certified translation into English (or Finnish), and if your degree is unfinished, please provide an official estimate of your graduation date We will review applications on a rolling basis. Only applications submitted through the universitys online application system will be considered.
