A pioneering research project in New Zealand is delving into the feasibility of underground hydrogen storage at a natural gas site in Taranaki. Led by PhD candidate Liu Jinjian and supervised by UC Associate Professor David Dempsey, the study models the injection, storage, and extraction of hydrogen to simulate the complex processes involved. The research underscores the importance of managing reservoir pressure, minimizing hydrogen loss, and maintaining gas purity for potential hydrogen applications. While challenges like contamination during extraction exist, the study aims to develop a framework applicable nationwide to optimize storage and tackle transport hurdles. Professor Dempsey emphasizes the strategic timing and precision required for injecting and extracting hydrogen underground, highlighting the potential for utilizing green hydrogen during surplus energy periods. This innovative approach could pave the way for New Zealand's hydrogen future and contribute to energy sustainability.
