HyCavern's goal is to develop and validate standardized, safe, and cost-effective hydrogen storage systems. These will take the form of artificially created, lined rock caverns. To achieve this, the project will combine technical lining systems, innovative materials, digital tools, and real-time monitoring technologies.
A key goal of HyCavern is to adapt cavern construction to various geological conditions, thereby making it scalable and replicable.
Two German partners are represented in the consortium
HyCavern is supported by the Clean Hydrogen Partnership and its members. It is being carried out under the leadership of Dr. Pierre Cerasi and Dr. Mohammad Masoudi of the research organization Sintef Industry.
The consortium is made up of research institutions, universities, and technology companies from across Europe. Among the partners are the Fraunhofer Institute for Laser Technology ILT and the mechanical engineering company Picum MT GmbH from Germany.
Project Develops Alternative to Conventional H₂ Storage Systems
The project is driven by the growing share of renewable energy in the European energy system. This is because hydrogen is expected to play a significant role in balancing supply and demand and supporting industrial decarbonization. However, many existing underground storage options depend on specific geological formations, which limits their use across Europe.
HyCavern is now focusing on the underground storage of hydrogen using lined rock cavern systems in regions where conventional underground storage facilities are not available .
Focus on Technological Development and Validation
Over the next three years, the consortium plans, among other things, to develop steel linings using laser welding and protective coatings to reduce hydrogen embrittlement and the risk of leaks. In addition, low-carbon concrete and rock interface systems will be tested to improve long-term structural integrity and environmental sustainability.
Other key areas include the development of simulation tools for the safe construction of cavernsin various geological environments, as well as the integration of monitoring systems such as fiber-optic sensors.
In addition, a GIS-based site selection toolkit is to be developed to support the deployment of the technology across Europe. Furthermore, the concept is to be validated under realistic operating conditions, and an assessment of its technical and economic feasibility and potential business models is to be conducted.
