The start-up
Sylfen produces the Smart Hub, adapted to cover a wide spectrum of power range and to ensure energy autonomy and flexibility in buildings and eco-districts. The Hub can store excess of energy generated by solar panels for several days or weeks, and can cover electricity and heating needs, even in periods of high demand or low renew. energy production.
The need
Although capable of using buildings to produce energy, there are still uncertainties regarding the security of the total energy supply required. Batteries alone cannot provide sufficient autonomy and an additional technological solution is needed.
The solution
Sylfen combines batteries with a reversible technology, acting firstly as an electrolyser to store energy in the form of hydrogen, and secondly as a fuel cell to produce heat and electricity from stored hydrogen or from biogas.
The value proposition
Sylfen offers an optimum combination in associating batteries and a breakthrough technology: the reversible electrolyser. This innovation is protected by 22 patents and allows for a compact hydrogen chain with low costs and high efficiency. Moreover, Sylfen’s development is oriented to serve the construction market with a highly modular product that is, thanks to its modelling tools, fully integrated, as well as optimised to each configuration.
