A research team from the University of Barcelona and the University of Granada is conducting a study at the Central Catalonia Geopark to evaluate certain geological formations as potential analogues for underground CO₂ and green hydrogen reservoirs. The focus is on understanding the quality and characteristics of these rocks rather than converting them into actual storage facilities. The region's unique geological history, dating back over 36 million years, has left behind rock formations that make it an ideal environment for research. The researchers are particularly interested in the well-preserved rock units from the former Sant Llorenç del Munt delta, which offer detailed insights into subsurface formations. Through a combination of outcrop data and drilling information, the team aims to create a comprehensive stratigraphic base of the area. Gas storage, including the injection of captured CO₂ into reservoirs, is seen as a crucial tool in the fight against climate change, especially for industries with challenges in decarbonization. The Central Catalonia Geopark, a UNESCO Global Geopark, is highlighted as a key ally in advancing research for carbon capture, storage, and addressing environmental and social challenges of the modern era.
