Applications/Product
Two families of uses, one single promise: simple & local autonomy
1. Decentralized Gaseous Hydrogen Consumers
Access to hydrogen autonomy
Elhytec has developed an integrated hydrogen storage and generation system that produces hydrogen on site, exactly when you need it — with no transport, no continuous high-pressure storage, and no supply disruptions.
Typical uses:
-
- –>Intermittent industrial hydrogen consumption
- –>Users facing strong installation constraints
- –>Specialized sites (meteorological balloon filling, alternator cooling, etc.)
Why choose the Elhytec storage/generator?
-
-
- –>Eliminates logistical constraints: local production, no deliveries, no supply interruptions.
- –>Optimizes site installation by reducing regulatory constraints
- –>Secures supply costs by eliminating transport and supplier volatility and keeping gas budgets under control.
- –>Enhances safety: no permanent high-pressure hydrogen storage.
- –>Ideal for sites with limited maintenance resources: unlike alternative solutions that require technicians, frequent adjustments, or regular inspections.
- –>Cost-optimized operation: hydrogen stock is replenished when electricity is available (solar, off-peak hours, etc.).
-
→ Local hydrogen that is simple, safe… and cost-effective, whatever your constraints.
Use Case & Product : Balloon Filling
A configuration specifically designed for meteorological balloon filling, providing on-demand hydrogen production at the flow rate required for daily radiosonde operations.
The solution replaces H₂ / He cylinders with a local, simple, and safe system, enabling:
- *Guaranteed gas availability at the exact time of launch
- *Drastically reduced costs and logistical uncertainty
- *Operation on isolated or poorly equipped sites
- *Short and predictable filling times
- *Consistent gas quality, ensuring lift performance and repeatability
Typical Specifications
- –>Batch volume: up to 4 m³ of gas
- –>Delivery pressure : up to 16 bar
- –>Gas purity: 99.9% (advanced purification optional)
- –>Filling time : 5 minutes
- –>System dimensions : 1.5 m × 2 m × 1.8 m (standard)
- –>Electrical power : 4 kW
- –>Industrial water supply
- –>Back-up operation in case of power outage
2. Hydrogen Storage for Guaranteed Power Supply
Long-duration storage for energy autonomy
Elhytec is developing a simple, safe, and cost-effective hydrogen storage system designed to be integrated into photovoltaic + battery architectures, enabling fuel cells or hydrogen engines to supply power 365 days a year, even in winter or under extreme conditions.
Typical uses :
- Isolated sites (mountain refuges and off-grid housing, scientific bases, telemetry stations, solar microgrids, etc.)
- Critical infrastructure
- Back-up power (telecom antennas, etc.)
- Seasonal energy storage
- Valorization of excess solar electricity
Key benefits
- Long-duration energy autonomy
- High operational flexibility
- Intrinsic safety (no continuous high-pressure storage)
- Full modularity: stored energy, charging power, and discharging power sized independently
- Innovative system architectures enabled by electrochemical decoupling
→ Clean, stable, and sustainable energy — wherever you are.
