TODO 2025: H2 Compressor Integration:
The hydrogen gas will be stored in a gas tank under pressure of 10 bars
compressor with normal gas filter
gas tank capable of holding 10 bar of hydrogen
Active carbon filter tubes for removing oil impurites in the hydrogen gas caused by the compressor
This is essential to protect the fuel cell components insuring longer life span

Some estimates from MetaAI:
[3:20 PM, May 17, 2025] Samir Mourad: The construction costs for a 25 kW alkaline electrolyzer fuel cell system can vary, but I can give you some general information.
Cost Factors
The costs of an alkaline electrolyzer fuel cell system depend on various factors, such as:
- Power: Costs increase with increasing power.
- Efficiency: Higher efficiency can lead to higher costs.
- Materials: Using higher-quality materials can increase costs.
- Manufacturing capacity: Costs can be reduced through economies of scale.
Cost Estimates
Some cost estimates for alkaline electrolyzer fuel cell systems are:
- Small systems (1-5 kW): €30,000-70,000
- Medium systems (5-25 kW): €70,000-200,000
- Large systems (25-100 kW): €200,000-500,000
For a 25 kW system, the cost could range from €150,000 to €300,000.
Other Costs
It is important to note that construction costs are only a portion of the total cost. Additional costs may be incurred for:
- Operation and Maintenance: Costs for operating and maintaining the system.
- Hydrogen Production: Costs for producing hydrogen.
- Infrastructure: Costs for installing and integrating the system.
Conclusion
Construction costs for a 25 kW alkaline electrolyzer fuel cell system can vary, but estimates range from €150,000 to €300,000. It's important to consider the overall cost and economic viability of the system.
