A clarion call for global collaboration to accelerate emission reductions and enhance climate resilience took center stage at the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), held in Belem, Brazil from November 10 to 21.

Focusing on the Belt and Road Initiative's (BRI) green development, and promoting global ecological cooperation, the "Belt and Road" Eco-industry Cooperation Working Committee of the All-China Environment Federation (ACEF) hosted a side event at COP30 in the UN Press Room, to share low-carbon practices and Chinese successful cases in this vital area of lowering emissions.

Representatives from five leading companies spanning new materials, automotive manufacturing, energy, and digital infrastructure presented their low-carbon transition roadmaps and results, to provide innovative, replicable practice schemes for the BRI partner countries.

A highlight of the ACEF session was the presentation by Changzhou Power Supply Company of the State Grid Jiangsu Electric Power Co., Ltd., which unveiled its "Electric-Steam Cube" solution. Designed to address the industrial dilemma of securing steam power that is sufficient, low-cost, and low-carbon, the technology offers a powerful engine for industrial green transformation.

The "Electric-Steam Cube" innovatively integrates three energy sources: photovoltaics (PV), off-peak electricity, and industrial waste heat. Utilizing electrode boilers and high-temperature heat pumps, the system produces steam at temperatures between 120 and 160 degrees Celsius.

To overcome the challenge of energy intermittency, the company developed large-scale thermal storage tanks. These tanks use high pressure to condense steam into water for storage; when needed, the pressure is released to revert the water to steam. The system achieves an energy conversion efficiency of over 95 percent, ensuring a continuous, stable, and flexible supply of clean steam.

Beyond the technology, the company introduced a collaborative business model combining "technology licensing and construction investment." By uniting energy service companies, equipment manufacturers, and energy consumers, the model has accelerated the large-scale adoption of clean energy technology.

To date, 118 of these models have been deployed across eight provinces in China, generating direct economic benefits of 830 million RMB. Environmental metrics are equally impressive: the system reduces carbon dioxide emissions in the steam production process by over two-thirds and completely eliminates sulfur dioxide and nitrogen oxide emissions.

Furthermore, the cost of the system is only one-sixth that of electrochemical energy storage. It functions as a flexible composite resource capable of responding within 30 seconds to absorb fluctuating PV power, thereby enhancing the stability of new power systems.

Observers said with wider promotion of the proven successful cases, the BRI green cooperation is entering a new phase. The initiative is solidifying its role as a "bond" in global climate governance, contributing Chinese wisdom and solutions to the building of a clean and beautiful world, in line with COP's vision.
