Air Liquide and Geostock have joined forces to tackle the challenge of storing gaseous hydrogen in large quantities for decarbonization purposes. The collaboration focuses on developing innovative technology for storing hydrogen, with a special emphasis on underground solutions. While renewable energy production plays a vital role in decarbonization efforts, the ability to store energy carriers like hydrogen at scale is crucial for its effective utilization. The partnership highlights the significance of establishing a robust supply chain for hydrogen, particularly in terms of storage. Underground storage options such as salt caverns and lined mined caverns are explored as favorable solutions. Salt caverns, known for their cost-effectiveness, are preferred where salt formations exist, while lined mined caverns cater to regions without such formations. These underground storage methods offer benefits like a small carbon footprint, safety due to minimal risks, and versatility in installation locations. Despite the advantages, challenges related to volume in underground storage need further investigation to address the growing demand for hydrogen storage globally. Overall, the collaboration between Air Liquide and Geostock showcases a positive step towards advancing hydrogen storage technology and contributing to decarbonization efforts in the industry and mobility sectors.
