Delphy Awarded at Hyvolution 2026: Vallourec Strengthens Its Role in the Hydrogen Value Chain
Vallourec participated last week in Hyvolution Paris 2026, the leading European event dedicated to the hydrogen ecosystem, held from January 27 to 29 at Paris Expo Porte de Versailles. This year’s edition confirmed its status as a key meeting point for professionals across the hydrogen value chain—and marked a milestone for Vallourec with the selection of Delphy, its vertical hydrogen storage solution, as one of the five winners of the show’s prestigious Innovation Award.
A Strategic Presence at a Pivotal Industry Event
Amid a context of market consolidation and slower growth in hydrogen project deployment, Hyvolution 2026 brought together a highly qualified audience directly involved in the industrialization of the sector. The event reinforced its positioning as a business‑centric platform fostering concrete exchanges among 550 exhibitors and 15,000 visitors including market leaders, innovators, and project developers.
For Vallourec, this environment offered an ideal stage to reaffirm its strong commitment to accelerating the development of green hydrogen infrastructure through robust, scalable industrial solutions. Despite the slowdown in market activity and event participation, Delphy continued to attract strong interest from industries seeking reliable and efficient ways to buffer green hydrogen supply. With Delphy, Vallourec is now well identified as a key player for the hydrogen storage market.
Storage brings value
The topic of hydrogen storage is gaining strong visibility, and Vallourec is actively highlighting how storage can significantly enhance project economics. Storage creates value—and by enabling large‑scale, onsite storage, Delphy makes this value fully accessible. This solution complements large‑scale grid infrastructure by offering a faster, more flexible, and bankable alternative for project developers.
Delphy Wins Innovation Award
Being selected as one of five Innovation Award winners at Hyvolution 2026 stands as a major recognition of Delphy’s breakthrough. This distinction highlights Vallourec’s ability to transform its long‑standing industrial expertise into tangible technologies capable of enabling large‑scale green hydrogen deployment.
Delphy is Vallourec’s market-ready underground hydrogen storage solution, capable of storing up to 100 tons of hydrogen gas vertically. Engineered to combine high-pressure performance, minimal surface footprint, and industry-leading safety, this turnkey solution has already been certified by Bureau Veritas and DNV, confirming its compliance with the most demanding safety and performance requirements. With this certification, the Delphy solution is fully ready for commercialization.
Since its launch, Vallourec has secured strategic partnerships with:
- H2V, a pioneer in large‑scale green hydrogen production
- NextChem Tech, a specialist in decarbonization technologies
- Geostock, a global expert in underground energy storage
These collaborations demonstrate the market’s confidence in Delphy’s potential to accelerate the development of hydrogen ecosystems.
Three High Level Conference Contributions
Beyond its booth and award winning innovation, Vallourec actively contributed to the event’s thought leadership program through three conference engagements:
1. Technical Presentation – How Delphy by Vallourec’s Hydrogen Storage Solution Enhances Production Value and Strengthens Your Business Case
Presented by Vincent Designolle, Delphy Director
2. Panel Discussion – Large-Scale H2 Storage: Better Energy Security and Grid Management
With Vincent Designolle, Storengy, Gasunie and Mincatec
3. Panel Discussion – H₂ Pipeline Networks: Growing Globally, Reshaping Possibilities
With Guillaume Néel, Hydrogen Marketing & Development Manager, Gasunie, RWE and Hydrogen Advisors
These interventions reinforced Vallourec’s visibility as a knowledgeable partner and a key contributor to future hydrogen infrastructures.
A Closer Look: Exclusive Visit to the Delphy Demonstrator
Following the event, Vallourec organized a dedicated tour of the Delphy demonstrator at its facilities in the North of France. A select group of hydrogen‑sector stakeholders was invited to explore the full‑scale installation firsthand, offering them an exclusive opportunity to deepen their understanding of the technology, discuss operational benefits, and engage directly with Vallourec’s experts.
A Strong Signal for the Future of Hydrogen Storage
Vallourec’s participation at Hyvolution Paris 2026 underscored the company’s strategic ambition to support the scaling of green hydrogen. With Delphy’s Innovation Award, growing industrial partnerships, and ongoing dialogue with ecosystem leaders, Vallourec demonstrated its capacity to deliver high‑value, ready‑to‑deploy solutions that meet the sector’s most pressing challenges.
As the hydrogen market continues to mature, Vallourec stands ready to contribute to the design and rollout of essential infrastructures supporting the global energy transformation.
