Exploring New Paths for Integrated Energy Solutions in Urban Green Development

Exploring New Pathways for Energy Integration and Initiating a New Chapter in Urban Green High-Quality Development

From April 29 to 30, the 8th Digital China Construction Summit was held in Fuzhou, Fujian Province. In the context of the ongoing national “dual carbon” strategy, the focus on urban green high-quality development has become a significant topic of public interest. On April 30, the Urban Green High-Quality Development Summit, themed “Building a New Ecosystem for Green Cities Together”, was successfully held at Hall 5 of the Fuzhou Strait International Conference and Exhibition Center. This summit concentrated on the key industry pathway of “integration of energy sources, grid, load, and storage”, gathering government leaders, industry experts, and industry peers to discuss how digital energy technology can empower urban green and low-carbon transitions, contributing to the achievement of dual carbon goals.

Accelerating the Construction of Fuzhou as a “Super Charging City”

Lin Cheng, Vice Chairman of the Fuzhou Municipal Committee of the Chinese People’s Political Consultative Conference, emphasized in his speech that Fuzhou, as a national pilot area for the innovation and development of the digital economy, is leading the way with its “Digital Fujian” strategy. The city is deeply implementing the dual carbon goals and promoting the integration of energy digitalization and urban greening. Fujian Province has closely aligned with national strategies, taking the lead in introducing multiple policies to support the “integration of solar energy, storage, and charging”. Fuzhou is actively responding by promoting the integration of solar energy storage and charging facilities with urban parking and transportation hubs, aiming to create a “15-minute charging circle” to assist in developing Fuzhou as a “Super Charging City.”

Transforming Cities into Green Low-Carbon Hubs

According to Cai Lingyu, Head of Huawei’s Digital Energy Strategy and Marketing Department, cities are the main battleground for green, low-carbon, and intelligent transitions, serving as new drivers for high-quality national economic development. Huawei’s AI-enhanced solutions for energy storage and charging networks allow for increased energy generation and use while ensuring safety, reliability, simplified operation, and automated management. Utilizing big data, AI, and integrated energy management, these solutions can accurately predict solar power output and electricity demand by modeling various data points, improving overall efficiency through coordinated cloud and edge computing.

Integration of Energy Sources, Grid, Load, and Storage Facilitates Urban Development

With dual carbon targets guiding efforts, green development has become a fundamental requirement for economic progress and social advancement. Urban platform companies must seize opportunities during their transformation to position themselves in the new energy sector, achieving economic, social, and political benefits. Cai Xu, Head of Huawei’s Digital Energy Commercial Expansion Department, highlighted that Huawei’s digital energy initiatives aim to merge digital technology with power electronics, advancing innovation through integrated solutions that empower urban platform companies to evolve into comprehensive energy operators, thus injecting new momentum into urban green high-quality development.

In this integrated approach: Sources transition from pure solar to solar-storage integration, enhancing the consumption of green electricity; Grids ensure reliable power supply and high-quality electricity for enterprises; Loads utilize “megawatt supercharging + grid technology” and distributed microgrids to minimize impacts on local grids and enhance overall profitability; Storage introduces advanced liquid-cooled storage cabinets, improving efficiency and reliability while extending lifecycle earnings by over 10%.

Successful Implementation of Green High-Quality Development Models

Heavy-duty trucks play a crucial role in urban low-carbon development. With the continued push towards electrification, especially in heavy trucks, a surge in adoption is expected. However, the current pace of electrification is slow, primarily due to slow charging and inadequate networks. Cai Cui, Director of the Logistics Center at the Ministry of Transport’s Highway Science Research Institute, suggested accelerating the establishment of a charging and battery swap infrastructure network for trunk logistics and creating intelligent service standards and platforms to facilitate the application of new energy heavy trucks in logistics.

Lin Yu, Chief Engineer of Fuzhou Urban Investment New Infrastructure Group, shared experiences from the “Rongcheng Xiaofu” project, where Fuzhou Urban Investment built a “super-fast charging” network through “hundreds of stations and thousands of piles”, creating a “10-minute charging lifestyle circle” for convenient green travel. Fuzhou Urban Investment plans to collaborate with Huawei to complete 34 all-liquid-cooled supercharging stations by the end of 2025, further promoting green low-carbon infrastructure and providing citizens with more convenient travel services.

Tian Long, Assistant President of Yudian Automation Technology Co., Ltd., illustrated his experiences with low-carbon park construction, emphasizing that the integration of digital technology and green energy can enhance energy management efficiency, reduce carbon emissions, and optimize economic benefits. Yudian’s “solar-storage integration” project at Xiang’an Industrial Park utilizes 781 photovoltaic modules across a 5,000-square-meter rooftop, resulting in a distributed solar power station with a capacity of 492 kW and a smart storage project of 216 kW/430 kWh. This system is expected to generate around 430,000 kWh of green energy annually, reducing carbon emissions by an estimated 420 tons.

Sun Xiaolei, Director of the Solar Storage Charging Product Line at Hangzhou Pinlian Technology Co., Ltd., highlighted the practical applications of integrated solar-storage-charging solutions. He emphasized that intelligent algorithms and collaborative cloud-edge technologies enable precise energy scheduling and efficient utilization, supporting urban low-carbon development.

At the summit, Huawei signed cooperation agreements with several Fujian enterprises, including Fuzhou Urban Investment New Infrastructure Group, Xiamen Guomao Group Co., Ltd., China Resources New Energy Investment Co., Ltd. Fujian Branch, and Sinochem Petroleum Fujian Co., Ltd. The collaboration encompasses intelligent charging networks, integrated solar-storage-charging solutions, and comprehensive smart energy initiatives, collectively promoting urban green high-quality development.

This summit thoroughly explored the application and practice of innovative digital energy technologies in urban green low-carbon development, recognizing that such development is a systematic project requiring collaboration among governments, businesses, and society. Moving forward, Huawei Digital Energy will continue to partner with industry stakeholders, driven by technological innovation, to propel urban green low-carbon transformations while actively exploring the application of digital energy technologies across various sectors, contributing to the achievement of dual carbon goals and creating a bright future for urban green high-quality development.
