Replace your Diesel Generators with Fuel Cells

SereneU ht-pem fuel cells convert hydrogen and other renewable fuels to electricity. Any Fuel. Anywhere. Low-cost, fuel-flexible, resilient fuel-cell technology. Meet your ambitious ESG goals by replacing diesel generators with our sustainable and future-proof technology! SereneU fuel cells work for back-up, supplementary and primary power – for rooftop, onground sites, in remote areas and in hybrid constellations.


Fuel cell systems are ideal for rooftop sites located in highly-populated residential areas, as they offer reduced noise and vibrations, having a minimum impact on people and surroundings.


Serene Systems are easy to install, operate and maintain. Systems with SereneU, 5-15kW, can be installed with an internal or external tank, depending on need.


Fuel cell systems are ideal for remote locations to support security networks and in telecommunications as they are compact to transport, have a high degree of reliability, excellent part load characteristics and high efficiency.

Hybrid to solar or wind

Advent SereneU fuel cells can work perfectly in hybrid systems with renewable sources such as solar and/or wind, providing uninterrupted power to mainstream sites but also sites that are challenged by extreme heat, wet offshore conditions, or located in remote areas as either back-up, supplementary or primary power.

Clean and reliable power for your telco site

We have 16 years of experience in the development of fuel cells and, until today, we have deployed hundreds of units for telco sites globally. Our fuel cells are ideal for replacing telco 4g and/or 5g back-up tower systems and off-grid power needs in remote, construction and bad-grid locations

SereneU-5 G4 by Advent offers a simple and reliable solution for on-demand power. Wherever there is a need for back-up, whether being commercial telecom networks, security networks, serene does the job. Not only does it deliver critical and reliable power, it also does it in an environmentally friendly way by reducing CO2 and operating in a silent way. On top of that, it is uniquely designed in a way where methanol is reformed on site to hydrogen. This means that the fuel for Advent systems is liquid and is not only easily distributed but also available all around the world. The system produces up to 5kW and as the system is modular, multiple systems can be interconnected.
