High density hydrogen storage and transportation is a challenge for stationary and portable applications and remains a significant challenge for transportation applications. Presently available storage options typically require large-volume systems that store hydrogen in gaseous form. This is less of an issue for stationary applications, where the footprint of compressed gas tanks may be less critical. To overcome these challenges Lr-H2 is pursuing two strategic pathways, targeting both near-term and long-term solutions. The near-term pathways are focused on compressed gas storage, using advanced pressure vessels made of fibre reinforced composites that are capable of reaching 700 bar pressure, with a major emphasis on system cost reduction.
The long-term pathway focuses on both two main strategies:
1. cold or cryo-compressed hydrogen storage, where increased hydrogen density and insulated pressure vessels, and
2. materials-based hydrogen storage technologies, including sorbents, chemical hydrogen storage materials, and metal hydrides.
