Ultra-pure hydrogen for CVD diamond production
On-site PEM electrolysis for CVD manufacturing
Hydrogen quality directly affects diamond growth, colour and yield. Endua’s PEM electrolysers enable reliable on-site hydrogen supply for stable growth conditions and consistent, high-purity outputs across CVD production environments.
Ultra-high purity hydrogen
Deliver consistent hydrogen quality suitable for gemstone-grade CVD processes, with system configurations compatible with downstream purification where higher purity grades are required.
Scalable supply architecture
Move beyond distributed small-scale generators with a hydrogen system that can scale with reactor fleets or multi-site operations.
Engineered redundancy
Reliable, high-purity hydrogen for brilliant CVD diamond production
Endua’s PEM electrolysers deliver consistent, high-purity hydrogen, enabling manufacturers to maintain stable growth conditions across long, uninterrupted production cycles.
Design systems with integrated storage, redundancy and backup strategies to maintain supply continuity during maintenance or unexpected disruptions.
Continuous, baseload operation
Uninterrupted hydrogen supply to support long-duration growth cycles, reducing the risk of contamination, batch loss or unplanned shutdowns.
Simplifying hydrogen supply across CVD operations
Endua PEM electrolysers give CVD producers greater control over hydrogen supply, reducing reliance on delivered gas or multiple small generators. Supply reactor fleets or shared production environments with centralised on-site hydrogen generation.
Centralised generation models
Support multiple reactors or production areas within a facility from a shared hydrogen system, reducing duplication of small-scale infrastructure.
Cluster and precinct supply
Enable hydrogen distribution across co-located manufacturers, supporting shared infrastructure models such as industrial clusters or diamond production hubs.
Future-ready infrastructure
Design systems that can scale and adapt to increased reactor density, higher throughput and higher purity or process requirements.
Integration with renewable energy
Pair on-site hydrogen production with solar or other renewables to reduce exposure to energy price volatility and support low-carbon diamond production.
Align hydrogen supply with your production setup
Every CVD operation is configured differently, with variations in reactor density, layout and gas handling systems. Endua works with manufacturers to assess hydrogen demand and purity requirements, designing on-site supply systems that improve control and simplify fragmented hydrogen infrastructure.
Take control of your hydrogen supply
Endua partners with CVD diamond manufacturers to assess hydrogen demand and optimise system configuration and supply architecture.

FAQs
-
On-site generation can be effective at small scale, but most facilities use compact hydrogen generators sized to individual reactor demand. Larger PEM systems are typically better suited to operations with higher or aggregated demand, such as multi-reactor facilities, expanding production sites or shared supply models across multiple operators
-
Yes, a single electrolyser can be configured to supply hydrogen across multiple reactors, provided total flow requirements are matched. Hydrogen is typically distributed via a central supply line with pressure regulation and flow control, allowing multiple reactors to operate simultaneously from a coordinated source.
-
Endua systems can scale with production demand, supporting higher flow rates as reactor fleets expand. This avoids the need to add multiple small generators over time, enabling a more coordinated supply approach that aligns with increasing throughput and reduces system complexity.
-
Endua systems can be configured with buffer storage and redundancy strategies to maintain continuous hydrogen supply. This supports stable operation across long CVD growth cycles, helping reduce the risk of interruptions that could impact product quality or result in lost batches.
-
As reactor numbers increase, managing multiple small generators can become complex and inefficient. A centralised system becomes more practical when hydrogen demand grows, infrastructure is being upgraded or facilities are looking to improve supply control and reduce duplication across operations.
-
Yes. PEM electrolysers can be integrated with existing gas handling systems, including piping, storage and pressure control. Where higher purity hydrogen is required, they can also be paired with downstream purification systems to meet more stringent specifications for advanced CVD applications.
