Abstract:: Hydrogen energy, as a core clean energy for achieving the “dual carbon” goals, often involves multiple extreme operating conditions in its application scenarios, including high pressure, strong acidity, low temperature, and long-term cyclic service. This imposes extremely stringent technical requirements on the key structural and functional materials in the core equipment of the hydrogen energy industry chain. Titanium and its alloys are critical materials for the whole hydrogen energy chain due to excellent corrosion resistance, high specific strength and good low-temperature toughness. This paper systematically reviews the application progress of titanium materials in key areas of the hydrogen energy industry. These key areas include proton exchange membrane water electrolysis, high-pressure/solid-state hydrogen storage, hydrogen transportation pipelines, and fuel cell bipolar plates. The review focuses on hydrogen embrittlement issues in hydrogen-rich environments, oxidation problems in oxygen-containing acidic environments,and forming challenges in complex components. It emphasizes the recent progress in titanium alloy composition design, anti-hydrogen embrittlement, surface modification and forming technologies. The aim is to provide theoretical support and technical references for promoting the large-scale application of titanium-based materials in the hydrogen energy industry.
