NITIU and partners develop sustainable hydrogen storage technology of the future

As the global energy transition accelerates and the demand for sustainable energy solutions increases, the HALDA project is developing an innovative solution for hydrogen storage. By improving storage efficiency and reducing climate impact, the project contributes to a reliable, low-emission energy supply.

Background

With the growing share of renewable energy in the global energy system, there is an increasing need for effective storage solutions. Hydrogen storage has been identified as a key solution to manage the variable production from sources like solar and wind. Today, hydrogen is most commonly stored in cylindrical pressure vessels, which limits the efficient use of space. Additionally, the materials currently used for hydrogen storage, such as carbon fiber composites, are energy-intensive to produce, have a high environmental impact, and are difficult to recycle at the end of their lifecycle.

Project purpose and targets

The HALDA project aims to develop and demonstrate a new, more sustainable solution for hydrogen storage. Using a patented design, ILS® (Isotropic Lightweight Structure), and an advanced laser welding technique, the project will develop modular tanks that can store hydrogen at high pressure in a significantly larger portion of the available space. This reduces the need for materials, which in turn lowers costs and environmental impact. A central aspect of the project is to demonstrate a production process that uses recyclable stainless steel, which, compared to carbon fiber composites, entails lower energy use and carbon emissions during manufacturing—estimated to be about 90% lower. In addition to reducing environmental impact, this solution could also extend the lifespan of the tanks compared to competing materials.
