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
