“We are happy to begin this valuable collaboration with Chemnitz University of Technology and Riga Technical University. Their expertise and knowledge in the field of sensors are essential to the success of this project”, says Mohamed Loukil, senior associate professor at Linköping University and coordinator of the project from the Swedish side.

This project (ISIMON) is a collaboration between Linköping University, Research Institutes of Sweden, Composite Services Europe (Sweden), Chemnitz University of Technology (Germany), and Riga Technical University (Latvia).
For the Swedish partners, ISIMON is funded by Vinnova through M-ERA.NET, an EU-funded network aimed at supporting and enhancing the coordination of European research programs and funding in materials science and engineering. The project is coordinated by Professor Olfa Kanoun from Chemnitz University of Technology.

Safety

The innovative ISIMON project was launched to develop smart high-pressure vessels in fibre-reinforced polymer composite, for storing hydrogen fuel. With the help of built-in thin sensors based on nanomaterials, the durability of the material can be monitored.

“This state-of-the-art technology aims to transform the hydrogen storage industry by improving both safety, reliability and maintenance efficiency”, Mohamed Sahbi Loukil adds.

"It is exciting to continue the development of small and high performing integrated sensors in composite materials with this consortium", says Mats Bergwall researcher at Research Institutes of Sweden, RISE.

Larger scale

The aim is to facilitate the use of hydrogen on a larger scale, extend the life and optimize the performance of storage vessels. In addition, the results are expected to benefit hydrogen storage, other gas storage solutions and filament wound components used in various industries.

“Adding functionality to the material with these types of sensors brings future possibilities to monitor the structural health of important structures for example in cars or gas tanks, which could be used to extend the lifetime of the product, to evaluate the structure continuously or in case of any unexpected event”, says Peter Larsson CEO of Composite Service Europe.

The ISIMON project uses carbon nanoparticles (NPs) such as carbon nanotubes (CNPs) and graphene oxide (GO) to reinforce polymeric materials, opening a new horizon for high-performance composites with smart properties for advanced sensing applications.

Such nanomaterial sensors will be embedded into the composite vessel directly during its manufacturing process, enabling continuous on-site monitoring of the vessel's structural integrity and performance from manufacture throuh its lifetime.

"Crucial"

"By embedding smart nanomaterial-based sensors directly in the vessels, we enable real-time monitoring. It is crucial to handle the high demands and safety standards required for hydrogen storage. It can also dramatically reduce maintenance costs and significantly improve safety and reliability”, says Mohamed Sahbi Loukil.

Details

The ISIMON project applies advanced modeling, simulation and machine learning techniques to optimize the design and functionality of smart vessels. Using ANSYS Finite Element software for detailed material models and applying topological optimization methods, the project aims to reduce material usage without compromising vessel durability or performance.

In addition, the project includes experimental tests and develops machine learning algorithms for real-time structural health monitoring (SHM). These smart sensors are designed to be fully compatible with the vessel's material, minimizing risks such as stress concentration points and thermal expansion anomalies.

Implementation of such advanced technologies for hydrogen fuel storage can enable safer, more reliable and cost-effective solutions. It opens up new market opportunities and paves the way for a wider use of hydrogen as a clean and sustainable energy source.

The project advances the technology in hydrogen fuel storage and sets a new standard for integrating smart sensing capabilities into high-pressure vessels. The ISIMON project is a step towards a fossil-free future, improving the energy and resource efficiency of these important storage solutions.
