Description

Underground storage is the most economical way to accumulate large quantities of hydrogen for later distribution.

The ability to store large volumes of hydrogen underground poses challenges in terms of hydrogen behaviour and evolution in contact with rocks in geological formations, hydrogen embrittlement/cracking of materials/components, hydrogen permeation, sealing and safety, all of which the H2SALT project aims to address.

Scope & Objective

In the H2SALT project, we are researching and developing the necessary technological solutions for the safe and efficient underground storage of hydrogen in salt caverns.

The main objective is to develop an integral system for hydrogen storage in a salt cavern based on the existing geological conditions and to determine its technical-economic feasibility for industrial projects. This includes the structural and behavioural analysis of the gas in the cavern, the tubular products for injection-extraction, the auxiliary installations necessary for the treatment of the gas before it enters and after it leaves the cavern, and the development of a business model.

To achieve this objective, the H2SALT project will address different main activities, divided into 5 lines of work:
