Cycle Innovations - Energy Storage Track

With continuing interest in clean energy and energy storage through the production and use of Hydrogen (H2), there is a growing need to fully understand the impact of H2 on existing infrastructure while also looking into the development of new technologies for future demand. This tutorial will take a detailed look into H2 applications and the challenges that it presents, whether it is the use of pure H2 or blending hydrogen with natural gas in existing pipeline infrastructure. Various applications that will be looked at are Propulsion, Petrochemical, and Energy Storage. In addition, this tutorial go over methods of H2 production and H2 compression to look at how the H2 is created and how it is injected into pipelines, fuel cells, and other forms of storage. In terms of compression, H2 presents many challenges due to its low molecular weight and high head rise to pressure ratios. It is important to look into existing technologies that are used for current hydrogen production but also understand their limits and capabilities while also looking into novel designs as demand continues to increase. After compression, there is a need to look into various methods for storing hydrogen, whether it is through liquid which will require more cooling, high pressure gas, carriers, sorbents, and additional options. Another challenge with H2, is its effect on materials typically used in pipeline systems. Due to its molecular size, hydrogen embrittlement at higher pressures is a serious concern as it could potentially weaken high pressure storage vessels and pipelines and lead to premature failure. This leads to a need to understand what materials are most effective with high concentrations of H2 while also understanding the impact on existing materials. This leads to a detailed breakdown of the potential for hydrogen blending and what concentrations are acceptable without compromising existing infrastructure to reduce cost and lead time for injecting more H2 into the pipelines. Lastly, the tutorial will look at H2 impacts on combustion by diving into combustion fundamentals, capabilities with current technologies, and novel designs that can improve performance with H2.
