The expertise group Applied Geosciences hosts about 70 professionals, for a large part earth scientists and subsurface engineers. Our project portfolio covers the entire chain of resource exploration, efficient production, subsurface storage, and the re-use and de-commissioning of existing infrastructure. Our project portfolio is diverse in scope and size: we manage large national research programs, participate in EU-funded research consortia, and provide consultancy services for the private sector. We offer our partners and clients – ranging from the global players in the energy sector to municipalities and from universities to start-up enterprises – a creative vision on the energy transition and transform this vision into practical solutions, based on world-class geoscientific expertise and leading edge technological capabilities.

What will be your role?

TNO offers a vibrant working atmosphere, with many opportunities for personal development and coaching. You will be given considerable room to develop, working closely in collaborative teams.

As a technical specialist in the Subsurface Energy Transition team within the Applied Geosciences department, you will help develop subsurface technology solutions that will enable the transition towards a carbon neutral energy system. You will be working on topics such as large-scale energy storage in the subsurface, the safe and environmentally benign re-use of gas and electricity infrastructure for renewable energy production, and optimal integration of the different activities in the subsurface into the rapidly developing and diversifying new energy system. Your role will include developing models in order to assess these systems and creating tools to assist in visualizing results, which may include standalone software as well as web applications.

You will have many opportunities to work together with clients on developing innovative solutions for complex problems faced by the energy industry. You will also have the opportunity to be part of multi-disciplinary research projects with a diverse group of geoscientists and engineers, as well as policy and economic experts.
