20-7 600 kmh MAGLEV nears production in Qingdao, Shandong Province

Launched in October 2016, the high-speed maglev train has a designed top speed of 600 km per hour and conducted a successful test run in June 2020. According to the China Railway Rolling Stock Corporation (CRRC), a train with five carriages has been running well on a test line within the factory. The train can travel with two to 10 carriages, each holding more than 100 passengers. It is said to provide the best solution for trips within a range of 1,500 km, filling a speed gap between aviation and high-speed trains.

13-7 Inner Mongolia will build solar power plant in sunken coal mine

The project is located in the coal mining area of Bazutao, Ulan Mulun Town, Inner Mongolia Autonomous Region. The site covers an area of about 2,800 ha, and total investment for a 500,000 kW solar power plant is 2.14 billion yuan (about 280 million €). In addition to solar power generation, the local government plans to carry out ecological restoration in the project area and develop cultivation and animal husbandry to build a smart solar-powered rural complex. The project is expected to be connected to the grid and start generating power by the end of 2021.

18-6 Carbon prizing will accelerate China’s energy transition away from coal

A systematic evaluation of the national carbon pricing effect on phasing out China’s operating coal plants has been conducted by a collaborative research team from the Institutes of Science and Development of the Chinese Academy of Sciences (CASISD), North China Electric Power University, University of Chinese Academy of Sciences, Tianjin University of Finance and Economics, and Beihang University. Using full-sample data of China’s 4,540 operating coal plant units and a stochastic Monte-Carlo financial model to assess the financial sustainability of the plant operation, and the lifetime change of each plant unit induced by carbon pricing, they found that although China’s operating coal plant units are young and have a long residual technical lifetime, many of their operations are close to the break-even state with the current policy and market conditions. According to the researchers, the carbon pricing effect on China’s phasing out coal power are mainly determined by the carbon price evolution, carbon permit allocation methods and the pass-through of the carbon cost to the consumer. Even with low initial carbon price of 50 CNY/tCO2 growing at 4%/y and the permits being fully auctioned, the average residual lifetime of all the plants will be reduced by 5.43 years, and the cumulative CO2 emission from 2020 to 2050 will be reduced by 22.73 billion ton. With the carbon price further reaching 100 CNY/tCO2, the operating coal plant stock is expected to be phased out 6 years earlier. Moreover, the disparity in the carbon pricing effect among China’s 29 provinces, autonomous regions and municipalities is significant and the western regions are more vulnerable to the carbon pricing risk than the eastern regions, with the residual lifetime being shortened by between 0.34 and 15.71 years via the carbon price of 50 CNY/tCO2

9-7 CAS Dalian Institute of Chemical Physics establishes metabolic engineering platform of Pichia pastoris

ZHOU Yongjin and colleagues developed novel genetic tools for precise genome editing in Pichia pastoris by enhancing homologous recombination (HR) rates and engineering the multiple intrusion-induced rearrangement (MIR) processes. The key gene RAD52, which played crucial role in HR repair in Pichia pastoris, was overexpressed for improving the efficiency of single gene editing to 90%. This advanced gene editing systems can theoretically realize stable loading of more than 100 exogenous genes and precise regulating of gene expression in Pichia pastoris, which will provide convenience for the synthetic biology research of Pichia pastoris.

8-7 China’s „2020 National Renewable Energy Power Report“ claims 15.9% non-fossil energy and 56.8% coal for primary energy consumption

According to the “2020 National Renewable Energy Power Development Monitoring Evaluation Report” released by the National Energy Bureau (Energy Bureau), the actual consumption of renewable energy power nationwide in 2020 was 2,161.3 billion kWh. The share of electricity consumption in society as a whole increased by 1.3 points from the previous year to 28.8%. The consumption of non-hydroelectric renewable energy power nationwide was 856.2 billion kWh, which accounted for 11.4% of the total power consumption of society. China’s non-fossil energy accounted for 15.9% of primary energy consumption, reaching the world average level. The share of coal consumption has dropped to 56.8%. China is strongly promoting a green and low-carbon model conversion of energy. It strongly supports the acceleration of the decline in carbon dioxide emission intensity. The carbon emission intensity in 20 years was 48.4% lower than in 2005.

5-7 China becomes world’s largest country for water irrigation on 37.8 million ha

According to the Rural Hydropower Bureau of the Ministry of Water Resources, the area of ​​water-saving irrigation in China as of the end of 2020 was 37.8 million ha. Of these, high-efficiency water-saving irrigation areas such as sprinkler irrigation, drip irrigation, and pipeline irrigation were 23.3 million ha. The irrigated areas occupy about 50% of the cultivated land area, produces 75% of the total food and more than 90% of the commercial crops. China’s agricultural irrigation water usage has maintained an average of approximately 340 billion cubic meters per year for nearly 30 years, accounting for about 56% of society’s total water usage.

5-7 CAS Hefei Institute of Physical Sciences develops nano-scale borate bioactive glass, applications in wound healing

The group of WANG Junfeng and colleagues have used a special mobile phase to pre-treat micron-sized borate bioglass by a melting method in vitro. They obtained nano-scale (~50nm) borate bioglass (Nano-HCA@BG), which was covered with an amorphous hydroxyapatite (HCA) layer.

During the processing, the ions (PO43- and CO32-) in the mobile phase were deposited on the surface of the glass to form the HCA layer, which effectively inhibited the rapid release of boron and calcium in the remaining glass and thereby reduced the biological toxicity of the glass itself to cells. In addition, HCA, as an important inorganic component in bones, has good biocompatibility, and can accelerate the induction of collagen synthesis in tissues. The results of in vitro degradation experiments, cell experiments, and animal experiments showed that compared with the existing commercialized bioactive glass, HCA and micron-sized borate bioglass, nano-HCA@BG slow-released boron calcium, and other elements can effectively accelerate wound cells migration and further up-regulation of the expression of vascular-related growth factors in the wound.
