Applications
Three families of uses, one single promise: simple & local autonomy
1. Decentralized Gaseous Hydrogen Consumers
Produce locally, when needed
The ElhyGas storage-generator produces hydrogen on-site, on demand —
without transport, without permanent gaseous storage, without supply disruption.
Typical uses:
- Intermittent industrial consumption
- Sites with strong installation constraints
- Specialized applications (meteorological balloon inflating, alternator cooling, etc.)
- Medium pressure needs (hydrogenation…)
Why the Elhytec solution?
- Eliminates gas logistics,
- Optimizes site installation by reducing regulatory constraints,
- Enhances safety: no gas storage, no pressure,
- Supplies cost control by removing transport/supplier volatility,
- Suitable for sites without advanced technical maintenance capability
- Cost optimization: opportunity to rebuild stock when electricity is available (solar, dynamic tariffs),
- Guaranteed and flexible operation: on-demand production, flow rate independent of available electrical power thanks to storage
→ Local, simple, safe… and cost-effective hydrogen, adapted to your constraints.
Use Case : Balloon Inflating
A configuration specifically adapted to radiosonde operations. The solution replaces H₂ / He cylinders with simple, secure local supply, enabling:
- Guaranteed availability at launch time
- Drastic reduction in logistics costs and uncertainties
- Operation possible on remote sites
- Short inflation time
- Gas quality adapted to lift and measurement repeatability
Typical Specifications

Chemical version (equivalent)
- for sites without electrical supply
- or in case of electrical failure
- or for mobile needs
2. Energy Storage for Guaranteed Power Supply
Elhytec technology addresses guaranteed power supply needs.
Its simple and safe hydrogen storage solution enables fuel cell and hydrogen engine applications for clean electricity generation and integrates as a long-term storage solution complementary to lithium batteries.
Typical uses :
- Backup power for critical sites (healthcare, telecom towers, data centers…)
- Remote sites (mountain refuges, scientific bases, telemetry stations, solar microgrids…)
- Valorization of intermittent or surplus electricity
- Seasonal storage
Why the Elhytec solution?
- Long-duration autonomy
- Intrinsic safety (no gas, no pressure, no thermal runaway risk)
- Independent sizing: stored energy / charging power / discharge power
- Simplified architecture thanks to decoupling
→ Clean, stable energy — anywhere.
Access to Pressurized Hydrogen for Critical Missions
For long-endurance missions, hydrogen changes the scale: it enables autonomy beyond batteries alone. In isolated environments, the main constraint is not only energy — but hydrogen logistics under pressure, required to compensate for the molecule’s low density.
Typical Use
- Refueling long-endurance hydrogen drones
Why the Elhytec Solution?
- High-pressure hydrogen delivery (350 bar) without compressor
- Simplified mobility and deployment
- Robustness adapted to field operations — no sensitive high-tech equipment
- Safety: no transport or accumulation of pressurized hydrogen or hazardous materials
→ A hydrogen solution designed for operational reliability and mission resilience.
