As interest in clean energy and energy storage through hydrogen (H2) production and usage continues to grow, it is imperative to thoroughly understand the impact of H2 on existing infrastructure while exploring the development of new technologies to meet future demands. This tutorial will provide an in-depth analysis of H2 applications and the associated challenges, whether involving the use of pure H2 or blending it with natural gas within current pipeline systems. Key applications to be discussed include propulsion, petrochemical processes, and energy storage, with a particular emphasis on H2 combustion.
The tutorial will also cover H2 production methods and compression techniques, detailing how H2 is generated and introduced into pipelines, fuel cells, and other storage forms. Due to H2's low molecular weight and high head rise to pressure ratios, compression poses substantial challenges. This session will examine existing technologies employed in hydrogen production, their limitations, and capabilities, as well as novel design considerations in the face of increasing demand. Compressed hydrogen storage options, such as liquid hydrogen, high-pressure gas, carriers, and sorbents, will be evaluated.
The tutorial will delve into the potential adverse interactions of H2 with pipeline materials, particularly focusing on hydrogen embrittlement at high pressures that can weaken storage vessels and pipelines, resulting in potential premature failure. The tutorial will include a detailed breakdown of the potential for the addition of H2 to existing pipeline infrastructure. Furthermore, the development of advanced gas turbine combustors to safely burn H2 without excessive NO and NO2 emissions stands as one of the primary challenges for hydrogen adoption. Hydrogen’s high diffusivity, flame speed, and adiabatic flame temperature all pose significant challenges to combustor design. The tutorial will present an overview of combustion fundamentals, contrasting pure H2 combustion with traditional natural gas combustion.
Finally, attendees will be introduced to state-of-the-art technologies being developed for hydrogen energy storage and gain insights into future industry trends and technological advancements.
