At the first meeting of the "Metode Numerik" course, I gained an understanding of the concept and application of the Numerical Method in solving mathematical problems through a numerical approach. This course also alludes to the importance of human awareness in accepting and processing problems, aiming to find solutions. In one of our class examples, we examine the expression (x^2-1)/(x-1) whereby direct substitution of x=1 results in 0/0 which is a number that does not have a consistent solution or logically defined. Then another method is used, such as limit or value approximation, the result is 2. However, this number is not absolute. Numerical methods are used to perform calculations and use the approach that produces the closest accurate value. It is important to note that these values are not certain, because absolute truth only comes from God Almighty

Design & Optimization of Pressurized Hydrogen Storage

To design the hydrogen cylinder, I utilized various resources, including existing tools like ChatGPT. I relied on ChatGPT to gather the necessary information for my design process. Here are the summarized outcomes and findings obtained through interactions and information searches with ChatGPT.

Design and optimize a pressurized hydrogen storage system with the following specifications :

  • Storage capacity : 1 liter
  • Pressure : 8 bars
  • Fee limit : IDR 500,000

First, we need to consider the design and material for the storage vessel. A common choice for hydrogen storage is a high-pressure cylinder made of a composite material, such as carbon fiber. These cylinders are light, durable and able to withstand high pressure. Considering the cost constraint, we will explore options that fit within the specified budget. To achieve this, we can consider the following approaches:

Cylinder Selection : Research and compare different options for hydrogen storage cylinders available in the market. Look for cylinders specifically designed for high-pressure applications and check if they meet the requirements of 1-liter capacity and 8-bar pressure. Consider factors such as material, weight, and cost. Choose a cylinder that offers the best balance between performance and affordability.

Material Optimization : Optimize the material selection for the cylinder while keeping the cost in mind. Look for materials that provide the necessary strength and safety while being cost-effective. Carbon fiber composite cylinders are commonly used for hydrogen storage due to their lightweight nature and high strength. Evaluate different materials and choose the one that fits within the budget.

Supplier Comparison : Reach out to multiple suppliers and request quotations for the selected cylinder. Compare the prices provided by different suppliers and negotiate for the best possible deal. Consider factors like warranty, delivery time, and after-sales support. Choose a reputable supplier that offers a competitive price and meets the requirements.

Safety Considerations : Ensure that the selected cylinder meets safety standards for pressurized hydrogen storage. Check if the cylinder has necessary safety features such as pressure relief valves, burst discs, and proper certifications. Safety should never be compromised, so prioritize cylinders that meet stringent safety requirements.

Cost Optimization : Explore cost optimization techniques such as bulk purchasing or negotiating for a lower price. Consider buying multiple cylinders to leverage volume discounts if applicable. Seek partnerships or collaborations with other stakeholders to share the cost of the system. By optimizing the procurement process, it may be possible to reduce the overall cost within the given budget.

System Integration : Evaluate the overall system requirements and consider any additional components needed for the pressurized hydrogen storage system, such as valves, regulators, and pressure gauges. Research and select cost-effective components that meet the system specifications. Ensure that the cost of these additional components is included in the overall budget.

System Efficiency : Consider system efficiency to optimize the hydrogen storage capacity. Explore options such as advanced compression techniques or thermal management systems that can maximize the amount of hydrogen stored within the 1-liter capacity. This will help to optimize the system's performance and make the most of the available storage space.
