Electrochemical hydrogen compression (EHC) has recently emerged as an alternative, but its optimal integration in an HRS is still to be determined. In this study, we compare the performance of a gaseous HRS equipped with different compressors: mechanical vs. electrochemical vs. combined. The design and operation of the compressors are optimized by solving multistage dynamic optimization problems. The optimization results show that the three configurations lead to comparable hydrogen dispensing costs, while the combined configuration is a trade-off with intermediate capital and operating cost.

this paper illustrates the use of the tubular structural catalyst module to improve steam-methane-reforming process as Honeywell and ZoneFlow Reactor Technologies announced recently an agreement to commercialize such a module. The structural catalyst module is based on “thermal sleeve” reforming reactor with higher thermal efficiency to reduce operational expenses. Thus, consuming less burner fuel and eliminating carbon emissions. structural catalyst improve heat transfer into tubular reactors by over 100% without increasing the pressure drop -flow indicator- across the reactor compared to conventional pellet catalysts .

Following over a decade of involvement in the gas turbine blade investment casting industry, I am eager to share some of my most Incredible experiences in several upcoming posts. The first area of focus is the development of a revised specification for Nickel-based superalloy IN738 LC (derived from the OEM specification) to hinder shrinkage defect and hot tearing during the investment casting process. In a groundbreaking advancement for the investment casting of nickel-based gas turbine blades, a modified specification for the IN738 LC superalloy has been developed, effectively minimizing the alloy's vulnerability to shrinkage defects and hot tearing. This achievement addresses one of the most significant challenges in the industry and has the potential to greatly improve the quality and performance of the final product. The modified IN738 LC superalloy specification is the result of an innovative approach that encompasses in-depth research, cutting-edge thermodynamic software, and a comprehensive review of existing literature. Combined with extensive practical experience, this breakthrough is set to further advance and refine investment casting processes for nickel-based gas turbine blades, contributing to the overall progress of the industry. Despite reducing the likelihood of hot cracking and shrinkage defects, the acceptance criteria for this alloy satisfy OEM specifications. By integrating this modified specification into the manufacturing process, a substantial decrease in shrinkage defects and hot tearing can be achieved, ultimately leading to enhanced product quality and performance. The successful development of this modified IN738 LC superalloy specification represents a significant step forward in overcoming the challenges associated with investment casting, and highlights the importance of continuous research and innovation in the field. #Gas_turbine_blade #Investment_casting #Superalloy #IN738LC #Shrinkage #Hot_tear

#Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. The working principle of lithium-ion battery is to achieve the mutual conversion of electrical energy and chemical energy through the embedding and extraction of lithium ions between the positive and negative electrodes, and the flow of electrons in the external circuit. During the charging process, lithium ions are extracted from the positive electrode material and embedded in the negative electrode material through the electrolyte and the separator. At the same time, electrons flow from the positive electrode to the negative electrode through the external circuit to form an electric current; during the discharge process, lithium ions are extracted from the negative electrode material and return to the positive electrode material through the electrolyte and the separator. At the same time, electrons flow from the negative electrode to the positive electrode through the external circuit to form an electric current.

One of the biggest hurdles to the widespread adoption of hydrogen in the propulsion and energy sectors is its notoriously complex storage and transportation requirements. Hydrogen’s high sensitivity to the environment, low compressibility, and high diffusivity complicates hydrogen storage and tank filling processes. CFD can help optimize tank design for maximum filling efficiency while minimizing the risk of equipment damage due to thermal stresses. In today’s #SimulationFriday video, we used CONVERGE to simulate hydrogen filling in a Hexagon 36 L Type IV tank with a 10 mm injector and validated the results with data from the HyTransfer project. To resolve the high jet penetration, CONVERGE’s mesh embedding was used along with Adaptive Mesh Refinement to accurately capture the jet profile and regions of high velocity gradients. Conjugate heat transfer modeling allowed us to assess the thermal fluctuations within the tank and identify the optimal materials for tank design. With its ease of use, accuracy, and rich set of features, CONVERGE is a highly effective tool for studying hydrogen tank storage. Want more details about how CONVERGE can simulate hydrogen storage? In our upcoming webinar on September 4, we’ll show you how our solver can tackle the complicated business of storing and transporting hydrogen—from filling and defueling tanks to complex piping systems with valves.
