Nokia claims that its liquid cooling 5G AirScale Base Station solution has helped Finnish mobile operator, Elisa, reduce the potential energy expenses of its base station by 30 percent and CO2 emissions by approximately 80 percent.
This is the first time a commercial 5G liquid cooling solution has been deployed anywhere in the world and highlights Nokia’s strong commitment to sustainability and combatting climate change.
The Nokia Bell Labs-developed solution will enable Elisa to achieve 30 percent lower power consumption and related savings at its site in Helsinki, Finland. Approximately 90 percent of energy consumed by base stations is converted to waste heat, however, with a heat re-use option – where waste heat is converted and repurposed – Elisa has been able to reduce its CO2 emissions by approximately 80 percent.
Liquid-cooled sites are silent, require zero maintenance, and can be 50 percent smaller and 30 percent lighter than standard active air conditioning units. They offer operators and owners of base station sites significant savings and potentially longer base station component life.
Sami Komulainen, EVP of Production, Elisa
Elisa has set a clear target to be carbon neutral at the end of 2020. We also want to maintain our 5G leadership and continue to be amongst the top operators in the world to offer the wide benefits of this new technology to our customers.
Tommi Uitto, President of Mobile Networks, Nokia
Our greatest contribution to overcoming the world’s sustainability challenges is through the solutions and technology we develop and provide. Nokia was first to introduce a liquid-cooled base station with the 2G, 3G and 4G base stations with Elisa in Finland.
