CryoSense - sensor principles for cryogenic liquid gas tanks

Hydrogen bears the potential of becoming an important energy source in the automotive field since its combustion leads to low emission of pollutants. In a mid-term view, hydrogen can play an important role as a sustainable energy source. The challenging task to develop a robust, accurate and cost-effective sensor for mobile and stationary tank systems has not been solved yet. The research project CryoSense focuses on the development and evaluation of sensor systems capable of measuring flow rate and fill level for liquid gas (primarily LH2). The project comprises a feasibilty study on a broad spectrum of measurement methods and, based on the results of the feasibility study, the design and implementation of experiment setups to evaluate the most promising methods. Since the cost and space restrictions for sensors in mobile tank systems are very stringent, the project is primarily focused on the development of sensor systems for stationary tank systems required e.g. at gas stations. However, methods that yield good results for stationary tanks, may be redesigned (miniaturized) for mobile use in a possible follow-up project.
