Context & Challenges
The energy transition requires massive electrification through renewable sources. However, their intermittency leads to critical imbalances between production and consumption. It is essential to have stationary solutions capable of storing this energy and delivering it at the right time, .

In order to:
- Stabilize the grid
- Avoid congestion and energy losses
- Absorb negative price spikes
- Ensure energy autonomy in isolated sites
- Secure critical systems (telecom, defense, healthcare…)

Elhytec is presenting its innovative hydrogen balloon inflation solution at the International Meteorological Exhibition in Vienna, October 2025. A safe, simple, and cost-effective technology enabling the transition from helium to hydrogen.

Elhytec and its Technology


Elhytec is developing an innovative long-duration energy storage solution based on a reversible zinc cycle — a non-strategic, recyclable, and industrially mature metal, with a stable price.
This technology safely and cost-effectively releases hydrogen, which can be used directly or reconverted into electricity or heat, depending on the applications.
Elhytec’s team builds on strong expertise in the fields of energy, electrometallurgy, water electrochemistry.
