Critical Power & Backup

Advent 5kW fuel cells excel at challenging power applications that rely on self-maintenance and remote monitoring

For critical power and back-up, the methanol fuel system by Advent Technologies A/S is perfect. This obviously goes for off-grid installations in remote sites, but in a grid-connected site, renewable energy system also offers all the economic advantages of a traditional grid-tied system like net metering and combines them with the energy independence and self-sufficiency of an off-grid system. The grid can be used as much or as little as desired, based on energy consumption needs and utility rates, because the combination of batteries and fuel cells always provide power to loads if the grid goes down or if peak rate charges are too high.

Besides being a clean technology, it is critical to always know the state of backup systems and to be confident in their reliability. Always knowing the state of the system especially for systems which always need to start up in case of break downs, is absolutely critical. You get exactly that with our fuel cells, which are self-maintaining and can be accessed remotely.

Stationary fuel cell systems also take up much less space in proportion to other clean energy technologies. Our fuel cell unit is recognised for being compact. This is a great benefit in high densely populated areas, where space scarce roof-tops, often small and difficult to access, are preferred installation locations. We already have specialized experience from more than several hundreds roof-top installations, where we can meet the various requirements for noise reduction, roof load and footprint.

This means that you can provide 240 hours of 1 kW backup or 48 hours of 5 kW, with a system that fits within 1 m2 – including both equipment and fuel! Moreover, at your convenience, it can easily be extended to more hours.

Clean, efficient and reliable power for your telco site

SereneU ht-pem fuel cells convert hydrogen and other renewable fuels to electricity. Any Fuel. Anywhere. Low-cost, fuel-flexible, resilient fuel-cell technology. Replace 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.


Serene fuel cell systems are ideal for rooftop sites located in high densely populated 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.


Serene 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

Serene 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.

Methanol Fuel Cell – providing Clean Power for Telecom Applications

Our system is simple and reliable for on-demand power generation for communication networks. Take a look at this video to see why our fuel cells are particularly fit for telecommunications.

Cases for inspiration

We have +15 years of experience in the development of fuel cells and until today, we deployed hundreds of units for telco sites globally.
