Nokia Launches 5G Liquid Cooling Tech, Going Carbon Neutral

It's deployed its new tech in Finland via one of the country's mobile operators, Elisa.

In what Nokia claims to be a world-first, the company has deployed its 5G liquid cooling base station technology in Finland via Elisa, a local mobile operator. The tech is meant to reduce power consumption and lower CO2 emissions

Moreover, the tech can allegedly cut base station site energy expenses by 30% as well as lower CO2 emissions by 80%. Nokia's liquid cooling was previously introduced to Elisa's 2G, 3G, and 4G base stations.

Win-win situation

Working in an energy-efficient manner is important to operators for two good reasons: it reduces their operating expenses, and it falls into line nicely with climate targets that many carriers and vendors have promised to commit to. 

When it comes to 5G this is extremely pertinent given its usual base stations consume up to twice or more power than a regular 4G base station, according to MTN Consulting.

As per Nokia's press release on the matter, around 90% of the energy used in base stations is converted into waste heat. However, with their new liquid cooling technology, there is the option to convert and re-use waste heat, which also reduces carbon emissions significantly — 80% in the case of Elisa's Helsinki base. 

This new liquid cooling tech works perfectly for Elisa, which had set the plan to be carbon neutral by the end of 2020. 

"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," said Elisa EVP of Production Sami Komulainen in a statement. "Innovations such as Nokia’s liquid cooling 5G base station demonstrate how 5G can help drive sustainability."

Nokia also chipped in by stating "We have demonstrated the world’s first liquid-cooled AirScale 5G base station in commercial operations, making liquid cooling a reality for all network generations," said Tommi Uitto, president of Mobile Networks at Nokia. "This innovative solution supports operators in their quest to be more environmentally responsible while allowing them to achieve significant cost savings."
