[ storage ]
Vallourec ’ s latest generation of advanced premium connections are qualified for hydrogen tightness .
potential leaks . By using specialized materials , the secure , long-term storage of hydrogen is ensured , especially under demanding conditions like frequent cycling .
Modular , customizable solution
This new storage solution is also modular , designed to respond to a broad range of storage capacity demands . Capacity can range from 1 to 100 metric tons , and storage can be customized to the specificities of the hydrogen storage requirement . Both capacity and pressure level can be adjusted as required , and the solution adapts to the onsite space available and optimal depth based on local soil conditions .
The system is also scalable . As demand for storage grows or decreases , tubes can be added or removed to adapt to the project ’ s evolution . This makes it a highly adaptable solution to maximize the efficient utilization of storage space .
Using modular and scalable vertical tube strings to store compressed hydrogen optimizes both operational expenditure ( Opex ) and capital expenditure ( Capex ). The initial investment is directly dependent on the required storage capacity but can be gradually increased over time . Upfront costs can thus be minimized , leaving the option to expand storage as time goes on .
Demonstrating the technology
To bring the solution to life , Vallourec built a fully functional demonstrator of its Delphy underground vertical storage system in Aulnoye-Aymeries , France . The demonstrator provides the opportunity to test the hydrogen storage technology firsthand , in a real-world setting . It operates at a small scale – with 150 kg of hydrogen – and is representative of all the main functions and steps in the value chain .
