Cutting-edge technologies and pioneering products featuring new energy and low-carbon development are being showcased at an international carbon neutrality expo in Shanghai, one of the country's vehicles for fulfilling its commitment to reaching peak carbon emissions by 2030 and carbon neutrality by 2060.

Themed "Path to Carbon Neutrality," the ongoing 2023 Shanghai International Carbon Neutral Technology, Products and Achievements Expo aims to promote the application of carbon-neutral technologies and the development of emerging industries, accelerating the green and low-carbon transformation of economic and social development.

Green, low-carbon applications in life, industry

The latest technologies involving energy transformation, circular economy, low-carbon services and transportation are on display at the expo.

The U.S. carmaker Tesla brought more advanced products beyond electric cars.

Megapack, a powerful energy storage battery, can store 3 megawatt-hours of energy per unit, enough to power 3,600 homes for an hour, said Tesla.

The carmaker announced in April that it is opening a Megapack factory in Shanghai, which initially plans to produce 10,000 units per year, equivalent to about 40 gigawatt-hours of energy storage.

Solar Roof, another Tesla energy product, "can completely replace the roof of home with its stress and hail resistance the same as the traditional one," said the exhibitor.

"The electricity generated from the roof can be stored in a small home energy storage device that is also on display, which can be hung on the wall to provide an emergency response in the case of a power outage. The product is maintenance-free, fuel-free, noise-free and is self-sufficient in electricity," the exhibitor added.

China Baowu Steel Group Corporation demonstrated its carbon-neutral metallurgical technology roadmap, which can help reduce emissions from the industry.

Baowu started constructing China's first million-tonne hydrogen-based shaft furnace project last year. After completion, it is expected to reduce carbon dioxide emissions by more than 500,000 tonnes per year compared to traditional processes.

The sensation of artificial intelligence has brought a soaring demand for computing power. It is also urgent to address problems concerning energy conservation and carbon reduction in cloud computing and data centers.

A liquid-cooled data server developed by China's Wangsu Science and Technology Co., a service provider for information infrastructure platforms, may shed light on solutions for such problems.

Compared to air cooling, direct liquid cooling (DLC) technology reduces heat consumption by 90 to 95 percent and server energy consumption by 10 to 20 percent, regardless of climate conditions.

It also doesn't require a refrigeration station, greatly reducing the power supply facility's size, nor does it need the traditional fans for IT equipment, cutting off the noise disturbance.

The technology is currently being used in the Jiading Cloud Computing Park, Shanghai's first immersion liquid cooling industrial park.

'World Low-Carbon Day' proposed on June 11

A low-carbon initiative declaration was released on Sunday.

It called on enterprises and social organizations to take the initiative to shoulder the social responsibility of resource conservation and environmental protection, implement the concept of green, low-carbon and circular development in the whole process of production and operation, and actively promote the research and development and application of green and low-carbon technologies.

All citizens are encouraged to purchase environmentally friendly products instead of disposable ones, practice garbage sorting, choose green travel alternatives and not waste food.

The declaration also proposed naming June 11, the expo's opening day, "World Low-Carbon Day."
