The Geothermal Institute at the University of Auckland has established a new research collaboration with Central South University (CSU), Changsha, Hunan, China, focusing on cutting-edge technologies for CO2 injection and mineralisation in geothermal systems.

This collaboration partnership was initiated during a recent visit by Associate Professor Biao Shu from CSU to the Geothermal Institute, where he met with Associate Professor Sadiq Zarrouk and Dr. Eylem Kaya. The visit included a tour of the Institute’s experimental facilities and discussions on advancing sustainable geothermal energy solutions.

The joint research will explore innovative methods for injecting carbon dioxide into geothermal reservoirs and their subsequent mineralisation. These technologies aim to enhance geothermal energy efficiency while contributing to global carbon reduction goals.

“This collaboration represents a significant step toward integrating carbon capture and storage with renewable energy production,” said Associate Professor Zarrouk. “By combining our expertise, we can develop solutions that address both energy needs and climate challenges.”

Central South University brings extensive experience in geothermal research and CO₂ utilisation, complementing the Geothermal Institute’s leadership in geothermal and reservoir engineering. The partnership will involve joint experiments, knowledge exchange, and potential student and staff exchanges between the two institutions.

Both parties expressed enthusiasm for the collaboration, which aligns with international efforts to decarbonise energy systems and promote sustainable development.
