The French company Vallourec wants to bring the energy future underground with Delphy, a hydrogen storage system that is as simple as it is ingenious.
How does it work?
The system is based on a revolutionary concept: the vertical and underground storage of hydrogen. Delphy combines a network of pipes and fittings with advanced technologies in a sort of underground "skyscraper" to guarantee maximum sealing and protection from corrosion.
Its storage capacity, up to 100 tonnes of hydrogen, makes it ideal for various sectors: green hydrogen production, industrial production, heavy mobility and electricity grid operators.
Underground storage: benefits and environmental impact
Choosing underground, vertical storage for hydrogen has numerous advantages. First of all, the optimization of space, fundamental in densely populated urban contexts or in complex industrial areas. Furthermore, underground hydrogen storage significantly reduces visual and environmental impact, blending harmoniously into the surrounding landscape.
The success of such a system would represent a crucial piece in the European energy strategy. France itself, the country where Vallourec is based, is positioning itself as a leader in the production of green hydrogen. The goal of the transalpines is to install water electrolysers for a total power of 6,5 GW by 2030. However, this commitment is also reflected in the efforts made by other European nations, with ambitious projects ranging from Germany to Italy, from Spain to Portugal.
Future challenges and prospects
Despite the indisputable innovation that Delphy represents, inevitable challenges arise. I mean, if they didn't exist we'd be full of systems like that, right? Scaling and integrating this technology into existing networks will require strategic collaborations, investments and, above all, a long-term vision. The excitement and confidence surrounding this project is palpable, though, and Delphy's potential to significantly contribute to the energy transition is indisputable.
Delphy could truly revolutionize the energy sector, and inspire new solutions for a cleaner and more sustainable world. In an age where sustainability is more of a priority than ever, that's no small thing.
