Nokia, KDDI trial Japan’s first liquid cooling innovation to ‘promote sustainability'

By

Nokia is conducting a trial using its unique Liquid Cooling AirScale Baseband solution with Japanese mobile operator KDDI.

Nokia says the trial will demonstrate how KDDI can reduce its baseband cooling system energy consumption by more than 70% compared to traditional gas coolant-based air-cooling solutions.

Nokia also says efficiencies can be further enhanced by the introduction of a heat reuse option that could yield a potential reduction of 80 percent in CO2 emissions and this is the first time a liquid cooling solution will be trialed in Japan “highlighting KDDI’s commitment to sustainability and combatting climate change”.

According to Nokia, traditional air-cooling systems are noisy and require regular maintenance such as filter changes and re-gassing, however, its Liquid Cooling solution is almost maintenance-free and virtually silent, making it ideal for buildings with tenants.

Nokia’s base station liquid cooling functionality captures heat into liquid directly where it is generated and removes it from the site by liquid circulation, supporting the reduction of cooling-system-related CO2 emissions by more than 70 percent.

Nokia also announced on Monday that KDDI is also trialing ITS Nokia AVA for Energy Efficiency solution which applies AI to support the challenge of rising energy consumption in networks.

Nokia says the solution helps to reduce overall energy bills by up to 20 percent and move towards more sustainable patterns of energy usage and AVA blends telecoms expertise, AI, and cloud-based delivery into a coherent energy control that “dynamically adapts energy consumption to traffic levels while maintaining a premium user experience”.

Nokia says it is committed to reducing the CO2 emissions generated by its technology, committing to cut emissions by 50 percent between 2019 and 2030 as part of its updated science-based climate change targets, in line with a 1.5°C warming scenario.

Nokia says this target covers emissions across its own operations and portfolio, logistics, and electronics manufacturing, and it intends to continue its efforts to research and develop solutions that reduce CO2 emissions beyond this trial.

“This trial is another milestone in Nokia’s commitment to sustainability and combatting climate change,” said John Lancaster-Lennox, Head of Market Unit Japan at Nokia,.

“Nokia was the first vendor to introduce this game-changing liquid cooling solution which supports operators in their quest to be more environmentally responsible while allowing them to achieve significant cost savings.”
