ECOHYDRO - More Economic and Ecologic Materials and Manufacturing Solution for Hydrogen Storage

ECOHYDRO aims to develop a new energy efficient filament winding process of hydrogen storage tanks using recyclable composites. We will develop multi-functional thermoplastic acrylic resin with fire-resistance, thermal insulation and self-healing capacity to enhance the safety of hydrogen storage, and hybrid tows to reduce microcracking. We will develop a recycling technology to recover 100% of carbon fibres and resin from hydrogen tanks after their end-of-life for the significant reduction of the cost and of carbon footprint of hydrogen storage tanks. To improve the safety and durability of hydrogen tanks, a new structural health monitoring technology via sensor integration into the tanks, will be developed in combination with data science using AI algorithm. These sensors embedded into the tank during the manufacturing process will be used to monitor the soundness of filament winding process in real time to improve the yield ratio. The developed technologies will be validated by four different types of industrial demonstrators (TRL4) using either compressed gas hydrogen storage or cryogenic liquid hydrogen storage, such as aboveground station, tube trailer, truck and bus, and aviation.
