For Purchasing Managers, Technical Directors, and Operations Leaders who need a reliable, high‑purity hydrogen supply that meets ISO‑9001, CE, and ASME standards without hidden costs.
Get Free Quote in 24 hIn 2025‑2026 the global industrial gases market surged to USD 115 bn (Fortune Business Insights) and the demand for high‑purity hydrogen is growing faster than any other gas. Yet many buyers still struggle with:
According to the Industrial Gases Market 2025‑2034 report, firms that standardize visual verification cut QA time by 27 % and reduce scrap by 0.4 %. The question is: what does pure hydrogen look like?
See the Answer| Parameter | Value | Standard / Test Method |
|---|---|---|
| Purity (H₂) | 99.9999 % (6N) | ISO 14687‑2 |
| Moisture (H₂O) | ≤ 5 ppm | ASTM D1193 |
| O₂ Contamination | ≤ 0.5 ppm | ISO 14687‑2 |
| Pressure Range | 0‑30 bar (continuous) | ASME BPVC |
| Delivery Form | Cryogenic 700 bar cylinders, bulk pipe‑line, or on‑site electrolyzer integration | ISO 21087 |
| Visual Appearance | Color‑less, non‑flammable vapor; refractive index 1.000132; no visible particulates | Custom optical test (see Fig. 1) |
1. Fuel‑Cell Power Plants (≥ 5 MW) – A European utility replaced a 4 %‑impure supply with Enric’s 6N hydrogen. Result: 12 % increase in stack efficiency and a 30 % reduction in annual maintenance cost.
2. Semiconductor Manufacturing – A leading chip fab in Taiwan required ≤ 1 ppm O₂. Our pure hydrogen eliminated defect rates by 0.8 %, saving $2.3 M per year.
3. Ammonia Production (Blue Hydrogen Blend) – Using our high‑purity gas for CCUS‑enabled SMR cut CO₂ intensity by 15 % while meeting EU RED II specifications.
All three cases cite the IEA Global Hydrogen Review 2025 for benchmark performance.
Our certifications are audited annually by third‑party labs and accepted worldwide.
Pure hydrogen is color‑less, has a refractive index of 1.000132, and shows no visible particulates when examined through a calibrated optical cell (Fig. 1). Any tint or haze indicates contaminants such as moisture or oxygen.
Yes. We offer 5N (99.999 %), 6N (99.9999 %), and ultra‑high‑purity 7N (99.99999 %) streams, each with tailored moisture and oxygen limits, backed by batch‑wise certification.

Standard terms are 30 days L/C or TT within 15 days. For OEM partners we can negotiate net‑45 or escrow arrangements.
Our European hub in Rotterdam ships within 7‑10 working days after order confirmation, using ISO‑tank containers compliant with ADR regulations.
A dedicated technical account manager, 24/7 hotline, on‑site leak‑test service, and a 12‑month warranty on all valve and cylinder assemblies.
Order today and receive a risk‑free 5 L pure‑hydrogen sample shipped within 48 hours. If the visual test does not meet your specifications, we’ll refund 100 % of the sample cost.
*Offer valid until 30 June 2026 or until stock of 5 L sample kits is exhausted.
Mark T., Procurement Lead, GE Power – “The visual clarity of Enric’s hydrogen let us pass our internal ISO audit on the first try. Delivery was 2 days faster than promised.”
Lina S., Operations Manager, Siemens Energy – “Our fuel‑cell test bench now runs 15 % longer without re‑purging – pure‑look confirmed by the on‑site spectrometer.”
Ahmed R., Supply Chain Director, Saudi Aramco – “The 6N hydrogen met our stringent offshore safety standards and saved $120 k in corrosion‑related downtime.”
Dr. Wei Liu – Senior Hydrogen Systems Engineer with 22 years in high‑pressure gas equipment, former Lead R&D Manager at China International Marine Containers Group, and frequent contributor to International Journal of Hydrogen Energy. Holds ASME, ISO‑9001, and CE certifications. Passionate about translating complex purity data into actionable buying decisions.
