Sunfire-Remote proven suitable for sustainable telecommunications infrastructure in a field test

Neubrandenburg, Germany, 9th December 2021

More and more operators of off-grid applications prefer fuel cells to traditional diesel generators. Sunfire-Remote has now demonstrated that CO2 emissions can not only be reduced to a quarter compared to diesel engines but as much as additional 90 % can be saved when operating with BioLPG.

The telecommunications sector is highly depending on flawless infrastructures at any times. Even off-grid systems like radio repeater stations must be continuously supplied with power. Looking for contemporary solutions, the industry is paying attention not only to reliability and maintenance efforts but also to climate protection.

Fuel cells are a practical solution to reduce the carbon footprint – especially when operated with LPG, like in the case of Sunfire-Remote. That gas is readily available all over the world and requires little logistical effort. While fuel cell generators running on LPG provide a clean supply for telecommunications systems everywhere, off-grid operators can make their applications even greener when sustainable fuels are available.

To prove this, Sunfire-Remote was supplied with BioLPG from PRIMAGAS as part of a field test of a leading German telecommunications provider. In constant full load operation, the fuel cells generated electrical energy to supply an application with a value of 72 g CO2/kWh. Compared with the emission value of grid electricity in Germany, the device thus saved 80 % of the emissions. Comparing the results with conventional diesel generator or battery application is even more striking: Sunfire-Remote running on BioLPG emitted 97.6 % less CO2, also avoiding any other harmful emissions when burning diesel.

Sunfire-Remote runs up to 10,000 hours without requiring proactive maintenance. Because of their simple use, the fuel cell devices are ideally suited for operating remote telecommunication infrastructures providing primary power. Additionally, Sunfire-Remote can be installed as a long-term backup of radio repeater stations or for permanent operation of emergency networks.

A leading U.S. telecom network operator already uses the innovative device at several facilities in North America. After a successful test phase in winter 2019, Sunfire Fuel Cells has delivered a double-digit number of power generators to Alaska for supplying microwave radio stations with power especially during wintertime, when PV supply is not sufficient.
