The reversible electrolyzer

At the hearth of Sylfen's innovative technology lies a reversible electrolyzer, bringing new functionalities: (i) it works as an electrolyzer to store excess of electricity in the form of hydrogen, and (ii) as a fuel cell to produce electricity and heat from that same hydrogen - or alternatively from (bio)-gaz

With a single device, we are now capable of storing large energy capacities, and give it back to the users whenever there is a need. This single point of entry makes installation and maintenance more economical.

This technology, developed in France, has demonstrated the best electrolysis performance in the world !

1/3 When your building produces too much energy

  1. Batteries are filling up
  2. Excess is converted into hydrogen and stored in a secured reservoir

2/3 When it isn't producing enough energy

 Batteries provide electricity to the building
 Some hydrogen is used to produce the missing electricity, together with some heat

3/3 In addition : cogeneration from methane

 When the stock of hydrogen is depleted, regular methane can be used to produce electricity and heat. This reaction, called cogeneration is highly efficient and allows you to value biogaz made locally.

 Also, it's possible to anticipate your energy needs by refilling your hydrogen supply when electricity from the network is cheap, or buying gaz instead of electricity.

Hybridation

Sylfen combines batteries for their power and fast reactivity, with hydrogen for its energy density and ability to store energy without loss.

We give you the best of both technologies for an optimized service !

Proprietary software suite for dynamic simulations

We have developed our own software capable of managing energy flux.

On top of that, we provide you with visibility on your consumption, transparency on its origin, so you can spot and make improvements.

We want these software to increase security, while improving over time. We work for continuous support and improved comfort.

  • Multi-sources energy supply are optimized
  • Adaptive to all energy profile: building, eco-district, ...
  • Continuous data analysis allowing self-learning improvements
  • Gain visibility on usages to raise awareness on responsible behaviour
  • Possibility to use this hydrogen for mobility (bike, cars, bus fleet)

My energy all year round with Sylfen
