More and more operators of off-grid applications prefer fuel cells to conventional diesel generators. Sunfire-Remote has now shown that CO₂ emissions can not only be reduced to a quarter compared to diesel engines, but, when operated with Bio-LPG, even a further 90% can be saved.
The telecommunications industry is highly dependent on flawless infrastructures at all times. Even off-grid systems such as radio converters must be continuously supplied with power. In the search for contemporary solutions, the industry pays attention not only to reliability and maintenance effort, but also to climate protection.
Brennstoffzellen sind eine praktische Lösung, um den CO2 -footprint - especially when they run on liquefied gas, as in the case of Sunfire-Remote. This gas is readily available worldwide and requires little logistical effort. While LPG-powered fuel cell generators provide clean power for telecommunications systems everywhere, off-grid operators can make their applications even greener if sustainable fuels are available.
To prove this, Sunfire-Remote was supplied with bio-LPG from PRIMAGAS as part of a field test by a leading German telecommunications provider. In constant full load operation, the fuel cells generated electrical energy to power an application with a value of 72 g CO2 /kWh. Compared to the emission value of grid electricity in Germany, the device thus saves 80 % of the emissions. Even more striking is the comparison of the results with conventional diesel generators or battery applications: Sunfire-Remote powered by BioLPG emitted 97.6% less CO2 and also avoided other harmful emissions when burning diesel.
Sunfire-Remote runs up to 10,000 hours without proactive maintenance. Because of their ease of use, the fuel cell units are ideal for operating remote telecommunications infrastructures that provide 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. telecommunications network operator is already using the innovative device at several locations in North America. After a successful test phase in the winter of 2019, Sunfire Fuel Cells has delivered a double-digit number of power generators to Alaska to supply microwave radio stations with power, especially in winter when PV supply is insufficient.
