Hello everyone ! My name is Muhamad Azkhariandra Aryaputra, you can call me Azkha. Right now I'm a Mechanical Engineering student at University of Indonesia and taking Numerical Method class with Pak DAI as the lecturer.

Hydrogen Storage Optimization

Hydrogen storage optimization entails enhancing hydrogen storage technologies' efficiency, capacity, safety, and cost-effectiveness. Because hydrogen has a low energy density, efficient storage is essential for its broad use as an energy carrier. Improving the efficiency, safety, and cost-effectiveness of storing and consuming hydrogen under high-pressure circumstances is referred to as optimizing pressurized hydrogen. Pressurized hydrogen storage is a typical approach for increasing energy density and making hydrogen feasible as an energy carrier. The key aspects of the optimization of hydrogen storage are :

Storage Tank Design: Optimizing pressurised hydrogen storage entails creating storage tanks that can bear high pressures safely. The materials used in the tank must be sturdy, lightweight, and resistant to hydrogen embrittlement. To attain the appropriate strength-to-weight ratio, advanced composite materials such as carbon fiber composites are frequently used.

Safety Measures: In pressurized hydrogen storage, safety is a vital factor. Implementing safety precautions to prevent leaks, ruptures, or explosions is part of the optimization process. This incorporates pressure release systems, burst discs, and stringent testing and inspection methods to assure the storage tanks' integrity.

Mitigation of Hydrogen Leakage: Minimizing hydrogen leakage is critical for ensuring the safety and efficiency of pressurised hydrogen systems. To reduce leaks, optimization efforts include the use of modern sealing technologies such as metal-to-metal seals or elastomeric seals. Regular maintenance, inspection, and leak detection procedures are also necessary to detect and rectify any potential leaks as soon as possible.

Material Compatibility: Optimizing pressurized hydrogen storage necessitates examining the hydrogen compatibility of storage tank materials. Hydrogen can induce embrittlement or penetration in some materials, resulting in decreased strength or hydrogen loss. To increase the longevity and performance of pressurized hydrogen storage systems, researchers are designing materials that are resistant to hydrogen embrittlement and penetration.

Compressed Hydrogen

The earliest and most essential element in the universe is hydrogen. It has the smallest atomic weight of any element and is made up of a positively charged nucleus proton and a negatively charged electron. Hydrogen is a colorless and odorless gas under typical or ordinary conditions. The most established hydrogen storage technique is compressed hydrogen storage, which includes the physical storage of compressed hydrogen gas in high-pressure tanks. Near-term technology for onboard car hydrogen storage currently consists of 35 and 70 MPa nominal working-pressure compressed gas containers. Compressed hydrogen is often kept in cylinders or high pressure tanks constructed of pressure-resistant materials. The pressure at which hydrogen is compressed varies, although it is often held at pressures ranging from 5,000 to 10,000 pounds per square inch (psi) or more. These high pressures enable more hydrogen to be stored in a given volume. Compressed hydrogen is employed in many different applications, such as fuel cell automobiles, industrial operations, and energy storage systems. It is an essential type of hydrogen storage, particularly for mobile applications, because it allows for relatively small and lightweight storage systems.

Material

The material that is used for this project is Aluminum 6061. Aluminum 6061 is a precipitation-hardened aluminum alloy comprising the principal alloying components magnesium and silicon. It has high mechanical qualities, is weldable, and is widely extruded (second only to 6063 in popularity). It is one of the most prevalent general-purpose aluminum alloys. The aluminum alloy 6061 is a significant raw material for aluminum liner carbon fiber full-wrapped composite gas cylinders, the hydrogen compatibility of which impacts the safety and dependability of gas cylinders to a large extent.

Design
