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
The Elhytec process, based on the principle of “split water electrolysis”, enables three successive functions: flexibly valorizing intermittent or surplus electricity, providing long-duration, stable and safe energy storage, and finally releasing hydrogen on demand.
The generated hydrogen gas can be used directly or converted into electricity or heat (via a fuel cell, combustion engine, or burner).
By combining the strengths of the process with a design approach based on readily available industrial components, Elhytec delivers a simple, ultra-low-Capex hydrogen solution that overcomes the complexity and high costs of conventional hydrogen value chains that have long hindered their deployment.
Elhytec’s team builds on strong expertise in the fields of energy, electrometallurgy, and water electrochemistry.
