Doctoral researchers in green hydrogen research

Do you want to build expertise in one of the most rapidly evolving fields of the clean energy transition? We are looking for two doctoral researchers to join LUT University's internationally recognised hydrogen research team and contribute to the development of renewable hydrogen production technologies for future energy systems. The Department of Electrical Engineering is hiring two doctoral researchers for a Research Council of Finland-funded project focusing on optimising the energy efficiency of high-voltage alkaline water electrolysis stacks powered by solar and wind energy. The positions are part of LUT's internationally recognised hydrogen research activities, which combine expertise in renewable energy systems, electrolysis technologies, modelling, optimisation, artificial intelligence, and fluid dynamics. LUT's hydrogen research team has more than ten years of experience in renewable electricity-based green hydrogen production. The team studies water electrolyser systems from a multidisciplinary perspective and collaborates closely with industry and leading universities in Finland and abroad. Its research has also contributed to the creation of several successful spin-off companies, including Solar Foods: https://solarfoods.com/, Elstor: https://elstor.fi/, and Neovolt: https://neovolt.fi/. What your work will be like In these positions, you will join LUT's hydrogen research group and contribute to the development of more energy-efficient alkaline water electrolysis technologies for renewable hydrogen production. Green hydrogen is expected to play a key role in the transition towards carbon-neutral energy systems, creating a growing need for efficient and scalable production technologies. As a doctoral researcher, you will conduct high-level scientific research as part of a multidisciplinary team and complete an article-based doctoral dissertation in English within four years. You will participate in research projects and contribute to scientific publications. Position 1: Modelling and AI-assisted optimisation of electrolysis systems In this position, you will further develop existing electrolysis system models and integrate them with AI-assisted optimisation methods. Your research will focus on modelling, simulation, optimisation, and data-driven approaches to improve system performance under varying renewable energy conditions. You will also apply artificial intelligence to next-generation hydrogen production technologies. Position 2: Fluid dynamics and optimisation of electrolysis systems In this position, you will contribute to the development and optimisation of alkaline water electrolysis technologies from the perspective of fluid dynamics. Your work will utilise fluid mechanics expertise to improve system performance and energy efficiency, supporting the wider deployment of renewable hydrogen technologies. The roles may also include teaching-related tasks and other duties supporting the activities of the research group. What we expect from you We are seeking candidates who are curious, aspire to an academic career, are committed to continuous learning, and want to contribute to scientific advances supporting the clean energy transition. You have a university master's degree (MSc or equivalent) in a field relevant to the position. Suitable backgrounds include electrical engineering, information technology, computer engineering, applied physics, applied mathematics, mechanical engineering, energy technology, fluid dynamics, or related disciplines. Position 1 requires strong analytical and problem-solving skills along with an interest in modelling, simulation, and the application of artificial intelligence to energy technologies. For Position 2, we expect a solid foundation in fluid mechanics, while experience in fluid dynamics-based optimisation is considered an asset. You will be required to apply to the LUT Doctoral School for the right to complete doctoral studies within the first two months of the appointment. In addition, you must be committed to completing your doctoral studies within the normative timeframe. Good written and spoken English skills, the ability to work independently and collaboratively in an international research environment, and enthusiasm for scientific research are essential. What we offer We offer an excellent opportunity to launch a successful academic career in a highly topical research area supporting the global energy transition. You will become part of an internationally recognised hydrogen research team and work on scientifically and societally significant challenges together with experienced researchers and industrial partners. The position 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 work starts as soon as possible, although the start date is negotiable. The jobs are based in Lappeenranta.The hours are flexible, sup
