Chapter 20 Underground hydrogen storage lessons for natural hydrogen systems
-
Quan Xie
Abstract
Natural hydrogen presents significant potential to transform the global energy system and accelerate the transition to a low-carbon future. Despite this promise, research on developing natural hydrogen systems remains limited. This study builds on the extensive work on underground hydrogen storage (UHS) in depleted gas reservoirs to leverage existing knowledge and expertise for advancing natural hydrogen systems.
Both abiotic and biotic geochemical reactions, which occur during UHS in depleted gas reservoirs, are also relevant to natural hydrogen systems. These reactions cause hydrogen conversion and contamination over geological timescales, leading to variations in hydrogen concentrations across hydrogen-detected wells in diverse geological settings, including orebodies, volcanic gases, hydrothermal systems, and oil and gas wells. These fluctuations in hydrogen composition underscore the need for quantitative research to establish the hydrogen-based equation of state. While the reactions in natural hydrogen systems differ from those in natural gas reservoirs, the underlying physics and governing equations for multicomponent flow remain consistent. Thus, modeling codes tested for UHS may be adapted to manage and predict the behavior of natural hydrogen reservoirs.
