At DESSERT
We focus on advancing underground hydrogen storage (UHS) technologies to support the energy transition. We aim to develop a cutting-edge production string prototype for the safe storage and extraction of hydrogen gas. Our innovative production string features high-quality threaded connections and stainless steel pipes, ensuring secure hydrogen containment across a wide range of pressures, temperatures, and loads.
WHAT WE DO
RESEARCH
- Define string specifications and testing procedures.
- Study hydrogen embrittlement in stainless steel.
- Assess leakage risks from the connection.
DESIGN
- Design advanced modelling of hydrogen embrittlement and seal tightness of the premium threaded connection.
ANALYSIS
- Analyse the integrity of different lubricated solutions exposed to hydrogen.
VALIDATION
- Determine the optimal make up torque for the application.
- Assess sealability under laboratory and real-world conditions.
- Ensure the reliability and performance of the connection design in practical and operational environments.
TECHNICAL STANDARD DEFINITION
- Draft a comprehensive testing guideline to validate threaded connections for hydrogen service.
- Ensure performance and reliability in hydrogen service conditions.
IMPACT
CONSORTIUM
The project, coordinated by TUBACEX INNOVACIÓN, spans 36 months and unites six partners from four EU countries (Italy, Spain, Germany and Austria), bringing together expertise across the entire value chain. The consortium comprises industrial steel manufacturers, research centres and academic institutions and a research-consulting company for ensuring a maximal exploitation and dissemination of the project results. With proven expertise in steel metallurgy, production processes, and advanced characterization techniques, the partners’ complementary skills and extensive experience enable a holistic approach to achieve the project’s objectives.
