On April 24, the National Energy Administration of the about inviting public "on strengthening the guidance of the new type of power system stable work opinion (draft)" opinions of the notice, notify, points out that to further strengthen stable work is the inevitable requirement to construct the new power system. Future quite a long time, will remain on the basis of ac power system technology form of ac power system stability problem will exist for a long time. Along with our country energy power green low carbon transformation was deepened, new energy power surge.

Since March, in order to alleviate inventory pressure, the silicon material industry has shown a stronger willingness to ship, and new silicon material production capacity has also been increasing month by month. At the same time, new production capacity for downstream silicon wafers is also being released simultaneously. However, according to TrendForce Consulting, silicon wafer production is still unable to fully consume the newly added silicon material production capacity and inventory, resulting in a slow decline in silicon material prices. The lowest quotation has reached 180 RMB per kilogram, but the current market average transaction price remains at around 190 RMB per kilogram. Meanwhile, as the first wave of silicon material production capacity this year will be concentrated and released at the end of the second quarter, it is estimated that silicon material prices will continue to decline from April to May.

On April 18, of energy, according to the announcement a-share stocks issued 2022 to A particular object of investment projects "annual output of 100000 tons of high purity silicon materials project", the main production facilities have production conditions are on March 15, 2023 and started production. Recently, the high purity polycrystalline silicon rod production line the first furnace successfully released and offline smoothly.

On February 18th, weichai released the world's first high power metal support commercial SOFC (solid oxide fuel cell) products. Site, the international authoritative testing institutions in Germany TUV she will group for weichai products issued by the European Union CE certification, product cogeneration efficiency reached 92.55%, hit a high-power SOFC cogeneration system efficiency is the highest record.

On September 5, the Chinese Academy of Engineering, shenzhen university distinguished professor he-ping xie team NiMeng with professor Hong Kong polytechnic university, nanjing university of technology professor shao published in nature - energy research. They are going to machine learning, combining theoretical calculation with solid oxide ceramic development, developed a screening after experimental verification of the cathode material of machine learning technology, quickly and effectively from huge perovskite component screening of highly active solid oxide fuel cell cathode materials.

At present, the organic pollutants in wastewater mainly adopts the traditional biological disposal technology, but on some of the wastewater containing high concentration, stable chemical structure of the organic pollutants effect is not ideal, such as pesticides, paper making, printing and dyeing wastewater, the toxicity of high concentration organic pollutant, big, complicated composition, mostly contains hard to degradation of the stability of the aromatic structure, biological sex difference, treatment is difficult, and refractory organic wastewater (Bio - refractor yor - ganic wastewater, BROW) removal of organic pollutants have become a difficult point in the sewage disposal of the category.
