In Wellington, New Zealand, a significant research effort led by PhD candidate Liu Jinjian from the University of Canterbury is underway to model the injection, storage, and extraction of a substantial amount of hydrogen underground in Taranaki. By simulating this process, the research aims to predict outcomes, identify challenges, and propose practical solutions for efficient hydrogen extraction. While storing natural gas underground is common practice, doing the same for hydrogen presents unique complexities, making it critical for New Zealand's hydrogen future. Associate Professor David Dempsey, supervising the research, highlights the necessity of managing reservoir pressure, minimizing hydrogen loss, and ensuring gas purity to make hydrogen storage viable. The research also addresses challenges like contamination during extraction due to mixing with natural gas or water, proposing possible applications in power generation or chemical processes. By viewing hydrogen storage as a buffer similar to water reservoirs, the study envisions a framework applicable across multiple sites to optimize storage and overcome transport obstacles. Professor Dempsey emphasizes the importance of precise timing in injecting green hydrogen, aligning with surplus energy production, and rapid retrieval during peak demand. This innovative research signifies a significant step towards unlocking New Zealand's hydrogen potential and shaping a sustainable energy future.
