Tenaris THera® portfolio covers a wide range of high pressure applications, with hydrogen storage masses ranging between a few kilograms for individual pressure vessels, up to several tonnes for multiple vessels installed into modular and stackable racks.

The core of these systems are Tenaris THera® monolithic seamless steel vessels, capable of withstanding extremely high service pressures. These are modular and flexible solutions in terms of both size and expandability.

Tenaris has a fully integrated production cycle and is the only high pressure hydrogen storage vessels manufacturer able to control the entire production, from steel making to the finished product.
