Huawei and ITU's Pioneering White Paper

During the MWC 2025, a significant milestone was reached as Huawei and the International Telecommunication Union (ITU) presented a white paper focusing on lithium batteries specially designed for telecommunications sites. The conference, which centered on the theme "AI Powering a Greener ICT," gathered leading telecommunications operators, industry pioneers, and experts worldwide to share insights and identify new opportunities under the umbrella of All Intelligence.

The Huawei Global Digital Power Summit emphasized the achievements made in carbon emission reductions over the last few years. However, Charles Yang, Senior Vice President of Huawei, noted that the climate crisis continues to pose serious challenges for humanity. The telecom sector alone contributes approximately 600 million tons of carbon emissions, making up 2% of the global total. Consequently, operators face three primary hurdles on the road to carbon neutrality: increasing emissions, high energy consumption, and rising energy costs.

To address these challenges, Huawei Digital Power is utilizing an innovative approach that merges digital technologies with power electronics. This integration offers low-carbon solutions across various operational scenarios, enabling telecom companies to transition from energy consumers to energy producers and facilitators.

Yang highlighted success stories from global operators that have, with Huawei's assistance, not only saved energy and reduced carbon emissions but also decreased operational expenditures on energy. For instance, in Pakistan, Huawei provided a PV plus energy storage system (ESS) solution, helping clients replace diesel generators with solar systems, cutting fuel consumption by an impressive 96% per location.

In another example, the transformation of 1,000 sites is projected to slash energy operational expenses by 38%. Furthermore, in Czech Republic, Huawei is aiding operators in extending backup durations while boosting revenues through participation in the electricity market using the same site ESS.

The innovative approach continued in Finland, where Huawei helped telecom operators aggregate ESS at telecom sites and in residential and commercial locations to engage in frequency response services in the electricity market, significantly increasing their revenue. Meanwhile, in Inner Mongolia, China, Huawei's customization of a subsystem decoupling solution upgraded an AI data center, enabling the rapid deployment of advanced language model services.

The impact of these initiatives is considerable. To date, Huawei Digital Power has facilitated clients in the ICT sector to generate 2.28 billion kWh of green electricity and save 81.6 billion kWh, equivalent to a reduction of 39.86 million tons of carbon emissions, which is like planting 54.46 million trees.

A pivotal outcome of the summit was the joint white paper between ITU and Huawei on lithium batteries tailored for telecommunications. This essential document advocates for the adoption of high-quality lithium batteries, demanding excellent performance parameters and underscoring the necessity of a comprehensive safety system structure. The paper also investigates safety challenges associated with lithium batteries in telecom settings, sharing contemporary research findings and best practices, while providing guidelines to enhance the safe and efficient use of these batteries in the communications industry.

Reyna Úbeda, an engineer at ITU-T SG5 dedicated to environmental issues, emphasized the importance of establishing standards for environmental efficiency within the ICT sector. Quality lithium batteries are crucial for storing and using energy more effectively in telecom environments, and thus reducing the overall carbon footprint of ICT operations.

In addition, a new white paper regarding the safety applications of lithium-ion batteries in data centers was released to promote their standardized and large-scale implementation in the sector. This offers a glimpse into a forthcoming era characterized by All Intelligence, where AI applications will present both opportunities and challenges regarding energy consumption while creating exhilarating development prospects for the global ICT industry.

Huawei Digital Power is committed to continuous investment in innovation and collaboration with like-minded global partners to forge new business value while constructing a greener, more sustainable future.
