Where [Hydrogen Supply] Creates [Production Risk]
LGD manufacturers encounter hydrogen risk from two directions — and the right fix depends on which one applies. If you are on delivered cylinders, the problem is supply and purity variability. If you are already generating on-site, the problem is likely an incumbent system that has become the constraint on purity consistency, uptime, or cost as production has grown.
Cylinder supply
purity variation between batches, supply interruptions during continuous growth cycles, handling costs that scale with production
Existing on-site systems
performance that was adequate at initial scale becomes a constraint on purity consistency and uptime as production grows
Both
inability to scale hydrogen throughput without significant logistics or capital overhead
Newer PEM electrolyser technology changes the performance and total cost of ownership equation materially. HYDGEN systems are designed to address both risk profiles.

Frequently Asked Questions
What purity of hydrogen is required for CVD lab-grown diamond production?
CVD diamond manufacturing requires a minimum of 99.9999% (6N) purity. Premium applications specify 99.99999% (7N). Critical impurities are trace oxygen (≤10 ppb), moisture (≤20 ppb), and hydrocarbons — all of which affect plasma chemistry and crystal colour grade.
Why is on-site hydrogen generation better than cylinder supply for CVD diamond manufacturing?
Cylinder hydrogen introduces batch-to-batch purity variation, supply interruption risk, and handling costs that scale with production. On-site generation produces hydrogen continuously to specification — no transport contamination risk, no delivery dependency.
Can HYDGEN systems scale with growing CVD reactor capacity?
Yes. HYDGEN's modular architecture allows individual units to be added in parallel as reactor capacity grows — without redesigning gas distribution infrastructure or incurring process downtime.
How does hydrogen purity affect diamond colour grade and crystal defects?
Trace oxygen and moisture introduce graphitic inclusions and colour-degrading defects. Hydrocarbon impurities alter the carbon source balance and affect growth rate uniformity. Consistent 6N–7N purity correlates directly with improved crystal transparency and reduced defect density.
What is the difference between PEM and AEM electrolysers for CVD hydrogen production?
PEM electrolysers are preferred for CVD applications at 6N–7N purity. They produce ultra-pure hydrogen from deionised water, operate at high pressure, and respond quickly to variable demand. HYDGEN offers both PEM and AEM systems — PEM is recommended for CVD applications requiring 6N and above.
