As China continues its relentless pursuit of ambitious carbon reduction goals, researchers are turning to innovative low-carbon technologies to accelerate the country’s transition to a zero-carbon future. From cutting-edge solar thermal power systems to experimental carbon capture and utilization techniques, the nation is investing heavily in experimental technologies to drive growth in upstream sectors and create new markets.
Supercritical Carbon Dioxide Solar Thermal Power Generation
One of the most significant advancements in this field is the development of supercritical carbon dioxide solar thermal power generation systems. This technology harnesses the sun’s heat to generate electricity, providing a clean and efficient alternative to traditional thermal power plants. The system, which uses CO2 instead of steam, has the potential to boost thermal-to-electricity conversion efficiency by 3 to 5 percent and cut carbon emissions by about 10 percent.
- The experimental system at the Institute of Electrical Engineering under the Chinese Academy of Sciences (CAS) uses a field of heliostats to track the sun’s movement and focus thermal energy onto three apertures on a central tower.
- These heliostats heat water, molten salt, and a novel type of ceramic particles to temperatures of 400, 600, and 800 degrees Celsius, respectively.
- The ceramic particles, which have been patented, heat carbon dioxide (CO2) via an innovative heat exchange process to 550 degrees Celsius, which powers the turbine for electricity generation.
Using CO2 instead of steam can provide several benefits, including increased thermal-to-electricity conversion efficiency and reduced carbon emissions. Research indicates that concentrated solar power (CSP) with CO2 propulsion technology can reduce emissions by approximately 60 percent compared to photovoltaic (PV) power generation.
New Opportunities in Nuclear Power
Another area of focus is nuclear power, where innovative technologies are being developed to enhance safety and efficiency. The world’s first land-based commercial small modular reactor, Linglong One, has reached a significant technological milestone with the successful installation of its first main pump.
| Nuclear Power Plant | Linglong One | Emissions Reduction | Capacity (kWh/year) |
| Country | China | 10 billion kWh/year |
The small modular pressurized water reactor, approved by the International Atomic Energy Agency (IAEA), is designed to provide district heating, desalination, and industrial heat. Its high-capacity scenario projects nuclear electrical generating capacity to be two and a half times greater than today by 2050, with small modular reactors accounting for a quarter of that growth.
Carbon Capture, Utilization and Storage (CCUS) Technology
China is also investing heavily in carbon capture, utilization and storage (CCUS) technology to reduce emissions from coal-fired power plants. The country’s first pilot project, which stores CO2 in bricks, has passed the 72-hour running test and will be used to produce aerated bricks, a widely applicable industrial product.
The use of CO2 in the production of aerated bricks has the potential to create new markets and industrial transformation. The national carbon emission trading market, launched in 2021, has covered over 2,000 power generation units, accounting for over 40 percent of the country’s CO2 emissions.
Strategic Alignment with Economic Value Creation
China’s green transition is now strategically aligning climate action with economic value creation, positioning low-carbon technologies as catalysts for new markets and industrial transformation. The country’s commitment to reducing emissions while driving growth has created a compelling narrative for investors and businesses.
As the world looks to meet its climate goals, countries like China are showcasing the potential of next-generation low-carbon innovations to drive growth, create jobs, and reduce emissions.
