High Pressure Hydrogen Gas — 200 to 300 bar supply for demanding systems
High pressure hydrogen gas from REAL GAZ serves systems that need more stored energy per litre, such as test stands, compressors and small storage banks.
Standard supply is 200 bar, and 300 bar cylinders and bundles can be arranged for equipment rated accordingly.
Standard supply is 200 bar, and 300 bar cylinders and bundles can be arranged for equipment rated accordingly.
Components should be specified to ISO 11119 and ISO 9809 for cylinders, ISO 10297 for valves and EN ISO 2503 for regulators.
At high pressure the choice of material is critical. Austenitic stainless steel 316L tubing and fittings resist hydrogen embrittlement better than carbon steel, and burst discs or relief valves must be rated below the weakest component. Filling rate is limited because adiabatic compression heats the gas quickly.
Safe operation at 300 bar rests on correct components and procedure. Pressurise slowly in steps, hold at each stage and inspect for leaks before continuing. Use ventilated enclosures or blast-protected cells for tests above the rating of standard laboratory equipment, and place pressure gauges where they can be read from a distance. Pressure relief should be piped to a safe outdoor location, because a discharge from a high-pressure hydrogen system can ignite spontaneously. Teams building a new rig may ask for a short list of rated components, and we are happy to compare pressure ratings, temperature limits and materials against your design pressure and test plan. Document every test: record the maximum pressure reached, the hold time, the temperature and the result of the leak check. These records help with internal audits and with later requalification of the same rig at a higher or lower rating.
🏭 Where High Pressure Hydrogen Is Used
