Dr. Fang Liangzhou, vice president and CMO of Huawei Digital Power, spoke at the recent COP26 session, ‘System change and climate innovation in the technology industry’ hosted by the UNFCCC Global Innovation Hub.

Liangzhou virtually delivered a keynote address on, ‘Building a low-carbon smart society.’ Liangzhou described how Huawei Digital Power integrates digital and power electronics technologies to help industries save energy and reduce emissions from both power generation and consumption.

Digitalization of power can cut waste in energy consumption, sharply boost power generation from renewables, and make transportation and cities green. Fang called for joint efforts to build a low carbon smart society together.

Liangzhou said, "Carbon neutrality has become a shared mission of the world. Technology innovation will play a central role in tackling climate change and achieving carbon reduction goals.

“Huawei Digital Power integrates digital and power electronics technologies, develops clean power, and enables energy digitalization to drive energy revolution for a better, greener future.

“We focus on converging and innovating on technologies to accelerate the digitalization of energy and enable various industries to upgrade. We aim to accelerate clean power generation, build green transportation, sites, and data centers, and work with industry partners to build a low-carbon smart society."

According to the International Energy Agency (IEA), the main sources of global carbon emissions are electricity, industry, and transportation.

The electricity and transportation sectors account for 40 percent and 21 percent of carbon emissions respectively. The ICT sector consumes four percent of global electricity.

To achieve carbon neutrality, low-carbon electricity production and electric energy consumption are a must. Huawei Digital Power works with partners to continuously innovate on energy production and consumption to achieve green and low-carbon outcomes:

Smart PV

In smart PV, Huawei develops a clean power system that focuses on renewable energy technologies such as wind, solar, and energy storage. In the Middle East, Huawei is helping Saudi Arabia's Red Sea Energy Storage Project supply power to the entire city.

This project will use the 400 MW PV + 1.3 GWh energy storage system, going to meet the energy requirements of millions of people in the future. Once the project is rolled out, the city will be the first in the world to be powered with 100% clean energy of PV and storage.

Energy digitalization

In energy digitalization, Huawei leverages a combination of digital and power electronics technologies to reduce consumption during energy conversion, storage, and use, thereby improving energy efficiency.

Huawei, together with China Southern Power Grid, uses AI technologies to automatically identify typical risky scenarios and defects on transmission lines. Thanks to the new preventive maintenance approach based on intelligent analysis and manual judgment, the time for completing onsite work is shortened from 20 days to two hours, improving the efficiency by 80 times.

Site power facilities

In Site power facilities, Huawei uses cabinets instead of rooms, and poles instead of cabinets to simplify sites, and has launched a series of off-grid fuel-removal power supply solutions to help carriers accelerate network carbon neutrality and bridge the energy divide.

For example, the carrier in Zhejiang, China used Huawei Site Power high-density eMIMO technology to replace six cabinets with one cabinet, reducing the footprint from 5m2 to 1m2 and improving the site energy efficiency from 85 percent to 96 percent.

They also adopted Huawei's green power solution where the unique iPV technology helps generate 20% more electricity, enabling PV to become the main power supply for green ICT networks and reducing carbon emissions by 8 tons per site each year.

Data center facilities

In data center facilities, prefabrication, modularization, and intelligent technologies are used to build simplified, green, intelligent, and secure next-generation data centers.

For example, Huawei's prefabricated modular data center solution helped Wuhan quickly build an AI computing center. The center was built in 120 days and put into use in 180 days, shortening the rollout time by more than 50 percent.

In addition, AI energy conservation technology is adopted to decrease the PUE to 1.25, which represents a saving of more than 3.4 million kWh of electricity each year. CO2 emissions can also be reduced by approximately 42,000 tons over the course of the life cycle.


In mPower, Huawei provides power domain solutions and charging infrastructure to accelerate the process of transportation electrification. For example, Huawei's DriveONE powertrain system helped SERES build the world's first mass-produced, high-performance electric coupe SUV with a cruising range of more than 1,000km, achieving 0–50 km/h acceleration in 1.99 seconds.

Tech for a better planet

Huawei adheres to the green pledge of ‘Tech for a better planet' and has continued to invest in reducing carbon emissions, promoting renewable energy, contributing to a circular economy, and conserving nature with technology.

As of September 30, 2021, Huawei Digital Power has helped customers generate 443.5 billion kWh of green power, save 13.6 billion kWh of electricity, and reduce carbon dioxide emissions by 210 million tons, which was equivalent to planting 290 million trees.
