Abstract

Summary

Uruguay presents important energy surpluses associated to the high penetration of renewable energy in its energy mix. One possible option to monetize this surplus of electrical energy is its conversion to hydrogen by electrolysis. This would represent large amounts of hydrogen and geological reservoirs rise as the only option to store such volumes. In this work we present the main properties of the cretaceous reservoirs identified as targets for underground gas storage in saline aquifers of Santa Lucía basin. Core and log data indicate good reservoir properties. Additionally, the thickness of clays suggests efficient seal properties. Results are encouraging and further work, including new data acquisition, is needed to confirm the closure of the structures. For the first time, the cretaceous reservoirs of Santa Lucía basin are considered as a solution for hydrogen storage. This could be the key to allow the storage of large amounts of surplus energy from renewable sources in Uruguay and positively impact towards the development of a hydrogen economy in the country. Presented parameters may be useful for further volumetric analysis, reservoir modelling and economic evaluations as well as site selection for a detailed infill survey and eventual pilot injection project.
