Kiwa ET

One of the largest test facilities for high-pressure hydrogen

High-pressure hydrogen test services

• For complete systems, containers and components
• Closed hydrogen cycle
• Environmentally friendly, cost-saving, 24/7 operation
• Compared to a hydrogen filling station: more than 40,000 refuellings per year

Test conditions

• Standards: ISO, GTR, UNR, EC, SAE, etc.
• Temperature range: -40°C to +85°C (for special tests -80°C to +120°C)
• Pressure: up to 87.5 MPa (for special tests up to 105 MPa)
• Pre-conditioned gas: -40°C to +85°C (down to -80°C for special tests)

Tests

• Leak tests
• Permeation tests
• Functionality tests
• Cycle tests
• Hydrogen embrittlement tests
• Durability tests
• Burst tests
• Hydraulic tests

Unique know-how and test facilities for liquid hydrogen.

Tests with LH2 and sLH2

• System function: refuelling, defuelling, hydrogen supply, insulation performance (dormancy), sensors, boil-off management, operation under tilt and roll conditions...
• Component function: valves, couplings (nozzle/receptacle), fittings, heat exchangers, sensors, pumps
• Safety: leak tests, hydraulic burst tests, rollover, loss of insulation vacuum...
• Material characterisation: temperature influence, hydrogen embrittlement, tensile tests, fatigue tests, fracture toughness, crack propagation...
