Context & Challenges
Growing demand for energy autonomy
The energy transition is reshaping how energy is produced, stored, and consumed. With the increasing variability of renewable resources and the need for reliable power at all times, energy autonomy is becoming a key requirement — for backup power, remote sites, microgrids, local mobility, and decentralized industrial processes.
Power autonomy for off-grid sites
In many situations — mountain shelters, monitoring stations, telecom sites, or microgrids — electricity comes solely from solar power and short-term lithium batteries. Integrating a renewable hydrogen storage cycle makes it possible to supply clean electricity all year round by converting solar excess into hydrogen and back into power whenever needed.
Local hydrogen generation: a flexible, low-logistics solution
Hydrogen is a key energy carrier connecting electricity, heat, and gas. Producing and storing hydrogen locally in a simple and cost-effective way reduces logistics complexity and enables new applications. In existing uses such as balloon inflation, these on-site solutions can accelerate the shift away from pressurized helium or hydrogen cylinder supply.

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.
