Design & Optimization of Pressurized Hydrogen Storage

Objective : Design and Optimization Of Pressurized Hydrogen Storage

Spesification :

Capacity  : 1 Litres

Pressure Level  : 8 bar

Limitation : Cost should not exceed Rp.500.000


Week 1 progress :

Before we dive deeper into the design & optimization phases, we must consciously understand the factors and processes involved in designing and optimizing the hydrogen storage first.

Select Tank Material

Hydrogen tanks are typically made from materials that are strong and capable of withstanding high pressures. Common materials used include alloy steel or carbon fiber reinforced with epoxy resin. Make sure the selected material has sufficient resistance to hydrogen corrosion.

Determine Working Pressure

Hydrogen can be stored in tanks either in compressed form or as a liquid. For compression storage, determine the working pressure based on your application needs. Higher working pressures require tanks with thicker and stronger walls.

Design Tank Structure

Hydrogen tanks usually have a cylindrical design with end caps. In the design, consider structural strength, tank mass, and thermal performance to avoid leaks or structural failures.

Consider Safety Systems

Safety is a critical aspect of hydrogen tank design. Ensure that the tank is equipped with pressure relief valves, and other necessary safety features to reduce the risk of hazards or accidents.

Cost Optimization

Minimize costs by considering factors such as material selection, manufacturing processes, and economies of scale because in this case the maximum cost to spend is Rp 500.000. Explore different manufacturing techniques, such as filament winding or automated fiber placement, to optimize production costs.

Test and Validation

Once the design is complete, conduct testing and validation to ensure the tank meets the required standards and safety regulations. Pressure tests, leak tests, and strength tests are some examples of tests that can be performed.
