2. The Ideal Gas Station utilizes existing off-the-shelf components, making the
station buildable today. The key features of the design include:
• Hydrogen obtained from existing suppliers
• 200 bar tube trailer delivery
• Dynamic cascade storage system minimizes compression
• On-demand cascade pre-cooling system
• Fast fill SAE TIR J2601 compliant dispensers
• 700 bar dispensing pressure doubles vehicle range
• Integrated pressure and leak-detection management
• Automated hydrogen ordering
• Remote maintenance and data collection
