Portland cement is the primary barrier material for well abandonment. However, the limitations of cement, especially under harsh downhole conditions, are necessitating research into alternative barrier materials. While several alternatives have been...

A coupled numerical model to assess the caprock geochemical integrity and porosity change of an underground hydrogen gas storage system. (2025)
Journal Article
ANTWI, K., AMBER, I. and OLUYEMI, G. 2025. A coupled numerical model to assess the caprock geochemical integrity and porosity change of an underground hydrogen gas storage system. International journal of hydrogen energy [online], 109, pages 624-635. Available from: https://doi.org/10.1016/j.ijhydene.2025.01.481

Hydrogen gas during subsurface storage in deep geological formations is prone to losses due to its unique hydrodynamic and chemical properties. These losses mostly induced by hydrogeochemical interactions between the stored hydrogen gas, brine and ca...
