1/ Pressurized Hydrogen Storage Optimization
- Pressurized Hydrogen Storage
- Pressurized hydrogen storage involves compressing hydrogen gas and storing it in specially designed tanks or cylinders. These tanks are built to withstand high pressures, typically ranging from a few hundred to several thousand pounds per square inch (psi). Pressurized storage offers advantages such as simplicity, portability, and fast refueling times. However, it also presents challenges related to weight, safety, and limited storage capacity. Tank materials must be robust, and strict testing is necessary to prevent leaks or ruptures. Alternative storage methods like cryogenic storage and hydrogen carriers are being explored to address these limitations and optimize hydrogen storage and utilization.
- Factors Involved in Designing and Optimizing a Pressurized Hydrogen Storage
- Designing and optimizing a pressurized hydrogen storage involves several factors and processes to ensure its safety, efficiency, and performance. Here are some key considerations in the design and optimization process:
- Storage Capacity
- The required storage capacity of hydrogen must be determined based on the anticipated demand and usage. Factors such as the desired duration of storage, refill frequency, and system requirements play a role in determining the storage capacity.
- Material Selection
- The choice of materials for the storage tank is crucial. Factors such as material strength, corrosion resistance, hydrogen compatibility, weight, and cost need to be considered. The selected material should meet safety standards, regulatory requirements, and be suitable for the specific application.
- Pressure Requirements
- Determining the optimal operating pressure is critical to balance storage capacity, tank weight, and safety. Higher pressures allow for more hydrogen storage within a given volume, but it increases material requirements and safety considerations. The pressure requirements should align with the intended use and regulatory standards.
- Safety Considerations
- Safety is paramount in hydrogen storage design. Factors such as material integrity, leak prevention, pressure relief mechanisms, and appropriate safety measures need to be incorporated. Standards and guidelines from regulatory bodies, such as the International Organization for Standardization (ISO) and national safety codes, should be followed.
- Structural Design
- The structural design of the storage tank must ensure its mechanical integrity and resistance to external loads, vibrations, and impacts. Finite element analysis (FEA) and other engineering calculations are performed to determine the optimal tank shape, thickness, reinforcement, and support structures.
- Thermal Management
- Hydrogen storage systems may require thermal management to control temperature variations. Insulation, cooling, or heating mechanisms are employed to maintain the desired hydrogen temperature range and prevent thermal stresses.
- Cost Optimization
- Optimization techniques, such as mathematical modeling and numerical methods, can be applied to minimize costs while meeting performance and safety requirements. This includes optimizing material usage, tank size, manufacturing processes, and other relevant parameters.
- Regulatory Compliance
- Compliance with relevant regulations, standards, and codes is essential in the design and operation of pressurized hydrogen storage. It ensures safety, environmental protection, and compatibility with industry norms.
- Hydrogen Purity
- The required purity level of hydrogen for the specific application should be considered. Impurities in the hydrogen stream can impact the integrity and performance of the storage system. Depending on the application, purification processes may be needed to remove impurities.

- Environmental factors, including temperature variations, exposure to corrosive substances, and seismic activity, should be taken into account during the design process. Adequate protection and design measures, such as coatings, seismic restraints, and environmental monitoring, may be required.
- Manufacturing and Fabrication Methods
- The manufacturing and fabrication techniques employed impact the quality, cost, and scalability of the storage system. Selection of appropriate manufacturing methods, such as welding, forming, or composite layup, needs to be aligned with the chosen materials and desired characteristics.
- CASE STUDY ANSWER
- Hydrogen Storage Type: Metal Hydride Storage System
- Metal hydride storage is a promising method for hydrogen storage optimization. It involves the use of solid-state materials capable of absorbing and releasing hydrogen gas through a reversible chemical reaction. These materials, known as metal hydrides, can store hydrogen at relatively low pressures and densities, making them suitable for compact and safe storage.
- Let's examine the potential of using a commercially available metal hydride alloy, such as LaNi5, as a case study. LaNi5 is a well-known metal hydride alloy that exhibits high hydrogen storage capacity and reasonable thermodynamic properties. It can absorb and desorb hydrogen gas at relatively low pressures, making it suitable for our requirements.
- Specific Calculations
- For this case study, let's assume we need a storage system that can store 1 liter (1000 cm³) of hydrogen gas at 8 bar (800 kPa) pressure. LaNi5 has a hydrogen storage capacity of approximately 1.5 wt% (weight percent). Therefore, we would need about 67 grams of LaNi5 alloy to store 1 liter of hydrogen.
- Considering the cost limitation of Rp 500,000, the cost of LaNi5 alloy can vary depending on factors such as market demand, supplier, and quantity. However, assuming a reasonable cost range of Rp 5,000 to Rp 10,000 per gram of LaNi5, the cost of 67 grams would be within the specified budget, ranging from Rp 335,000 to Rp 670,000
- Other Considerations: Metal Hydride Storage System Advantages
- Metal hydride storage systems offer advantages such as moderate operating temperatures, inherent safety due to the chemical stability of metal hydrides, and the ability to store hydrogen at low pressures. However, they also have limitations, including relatively slow hydrogen absorption and desorption kinetics, which can affect the system's efficiency and performance.
