In 2023, we continued to vigorously advance the development of new energy businesses, guided by the goals of the "14th Five-Year Plan". Efforts were made to continually improve the business framework of "4 Supplies and 2 Integrations", aiming to establish a diverse system for supplying green energy and ensuring the orderly implementation of various initiatives. Progress in the hydrogen energy industry remained steady, with wind and solar power capacity surpaassing 1,000 megawatts. Construction of charging and battery swap facilities was completed ahead of schedule to meet the targets set in the "14th Five-Year Plan", while maintaining a leading position in clean heating.

Hydrogen Energy

In August 2023, the Xinjiang Kuqa 20,000-tonne/year green power green hydrogen demonstration project was fully completed and put into operation, marking the world's first and largest project that directly produces green hydrogen from PV power. During the trial operation period, it produced a cumulative 2,359 tonnes of hydrogen. The Ordos 30,000-tonne/year wind-solar green hydrogen integration project commenced construction. The long-distance hydrogen pipeline for the Ulanqab 100,000-tonne/year wind and solar coupled project that produces green hydrogen from green power was included in the implementation plan of the "National One Grid". Thirty new hydrogen refueling stations were constructed, bringing the total to 128 stations completed. The construction of our first overseas hydrogen refueling station, the Au Tau Comprehensive Energy Refueling Station in Hong Kong, commenced within the year. The total capacity of hydrogen purification and refueling facilities reached 29,000 m³/h. Research and planning for the national hydrogen corridor demonstration line were underway. Focusing on major scientific and technological research topics on hydrogen energy, efforts were made to advance the work in an orderly manner, resulting in breakthroughs in key technologies.

Wind and Solar Green Power

The new wind and solar green power capacity surpassed 1,000 megawatts. This achievement realized a cumulative installed capacity of 1,700 megawatts, enabling an annual generation of around 2.3 billion kw-h of green power and significantly enhancing our clean energy supply capacity.

The Company maintained its leading position in clean heating by actively promoting innovative modes such as "Geothermal+" and "Residual Heat+". We continued to advance the development of geothermal heating business, leveraging high-quality resources in regions like Beijing-Tianjin-Hebei and the Bohai Bay Basin. The newly constructed geothermal heating capacity exceeded 12 million square meters. By the end of 2023, we had established over 95.9 million square meters of clean heating and cooling capacity, along with a residual heat utilization capacity surpassing 40 million GJ/year. We made strides in the deep geothermal field. Our inaugural geothermal scientific exploration well, Fushan Thermal 1, was successfully drilled in Haikou, marking China's first 5,000-meter-deep, high-temperature geothermal exploration well.

Comprehensive Charging Stations

The development of integrated energy refueling stations gained momentum, with the construction of charging and battery swap facilities surpassing the targets set in the "Fourteenth Five-Year Plan". Nearly 3,500 new charging and battery swap stations were added, bringing the cumulative total to 6,502. Additionally, 1,100 new gasoline-supporting photovoltaic stations were constructed, totaling 3,552. The sales of E10 ethanol gasoline amounted to 16.856 million tonnes, while the sales of bio-diesel reached approximately 502,000 tonnes.
