Apr. 18, 2025On April 16th, Jakarta, Indonesia - Amidst the global energy transition wave, Shen Chao, the Southeast Asian regional leader of Bairong New Energy Technology, made a heavyweight appearance at the 2025 Indonesia Global Hydrogen Industry Ecological Chain Forum with his "Compressed Carbon Dioxide Energy Storage Technology". To provide an integrated innovative solution of "new energy+carbon dioxide energy storage" to solve the problem of power shortage on islands, continuously outputting stable power for 24 hours to provide power guarantee for islands. Using Chinese technology to assist Indonesia in building a new sustainable energy ecosystem.
Compressed Carbon Dioxide Energy Storage Technology: Innovative Power of Energy Storage Earth Hour
Carbon dioxide energy storage technology is a new type of energy storage technology with completely independent intellectual property rights, led by Bairong New Energy Technology and jointly developed by the School of Energy and Power at Xi'an Jiaotong University. The basic principle is based on thermodynamic cycles and the physical properties of carbon dioxide. During the energy storage stage, the ambient temperature gaseous CO ₂ is converted into high-pressure and high-temperature CO ₂ through multi-stage compression. Through heat storage and condensation, it is transformed into liquid CO ₂ and stored; During peak electricity consumption, high-pressure liquid CO ₂ absorbs the heat stored in the energy storage stage and converts it into high-temperature and high-pressure gaseous CO ₂, which drives the turbine unit to generate electricity.
This technology has many significant advantages, including long operating life, closed-loop operation, zero carbon emissions, and fast response speed (minute level start stop), providing an economical and environmentally friendly technical solution for power grid peak shaving and renewable energy consumption. More importantly, in the process of achieving the goal of "carbon peak and carbon neutrality", this technology can use the carbon dioxide collected during the production process as a working medium, which not only solves the problem of energy storage, but also opens up new ways for the resource utilization of carbon dioxide, and helps the global carbon reduction industry.
Distributed negative carbon green power station: an ideal solution for island electricity consumption.
Distributed negative carbon green power station is an innovative application scenario based on compressed carbon dioxide energy storage technology launched by Bairan New Energy Technology. Its unique operating mode and significant advantages make it an ideal answer to island electricity demand.
Operating mode
The power station is supplied with new energy electricity (photovoltaic, wind power) as raw materials, and a power generation system is built around the gas-liquid phase change of carbon dioxide, which can achieve 24-hour stable green power output.
Significant advantages
Zero carbon and negative carbon: From the source, driven by green electricity and clean energy, achieve zero carbon at the source; In the construction and operation of the system, no carbon emissions are generated, and the carbon dioxide working medium is non-toxic, producing no pollutants throughout its entire lifecycle, achieving zero carbon and zero pollution in the process.
24/7: Carbon dioxide energy storage technology has successfully overcome the bottleneck of fluctuations and time constraints in new energy electricity, converting unstable new energy electricity into green electricity that can achieve stable output 24/7, providing continuous and reliable power guarantee for islands.
Flexible deployment: it does not depend on geological conditions and is not restricted by environmental temperature. It can be built in cold, temperate or tropical areas, or in high altitude areas, Sago wasteland, saline alkali land, mudflat, garbage backfill, the original site of thermal power station in the closed mining area and other special landforms and complex plots, with wide applicability.
Intrinsic safety: The pressure and temperature levels are relatively low, with pressure less than 7.0MPa and temperature not exceeding 300 ℃, greatly reducing the possibility of safety accidents caused by high pressure and high temperature. Meanwhile, carbon dioxide is an inert gas that poses no risk of combustion or explosion, ensuring the long-term stable and safe operation of the power plant.
Grid friendly: The capacity and efficiency of energy storage stations will not decline during their 30-year lifecycle. It provides electricity with rotational inertia and can provide comprehensive auxiliary services such as active, reactive, and emergency for the power grid.
Due to their remote geographical location, many islands face many challenges in traditional power supply methods, such as difficulties in laying transmission lines, poor power supply stability, and environmental pollution caused by dependence on fossil fuels. A distributed negative carbon green power station based on carbon dioxide energy storage system can operate independently and provide all-weather stable green power services for island users. This not only reduces the dependence of islands on traditional energy and lowers investment in transmission and distribution facilities, but also ensures the autonomy and stability of local power supply, greatly improving the quality of life of island residents and promoting the sustainable development of island economy.
The presentation of Bairang New Energy Technology at the 2025 Global Hydrogen Industry Ecological Chain Forum in Indonesia has shown the world the enormous potential of compressed carbon dioxide energy storage technology. The combination of this technology with distributed green power stations marks the transition of the island energy revolution from technological breakthroughs to large-scale implementation. Bairang New Energy Technology looks forward to building a zero carbon ecosystem with global partners, making every island a beacon of green transformation.
