Since the beginning of this year, new wind power and solar energy projects have been launched across the country, and the energy storage market has exploded. As an emerging energy storage station operation model, shared energy storage has received more and more attention. A large number of shared energy storage stations have been built in Guizhou, Zhejiang, Jiangsu and other places. In Yangkou Town, Nantong City, Jiangsu Province, next to the wind power and photovoltaic project are rows of shared energy storage power stations composed of white energy storage cabins. The person in charge said that this project was connected to the grid on November 29, with an investment of more than 790 million yuan. The excess electricity generated by multiple surrounding wind power and photovoltaic power stations can be stored to provide power to residential areas or industrial enterprises. Shang Sen, the person in charge of the operation and management of a shared energy storage power station in Nantong, Jiangsu: In terms of scale, it is currently the largest large-scale shared energy storage power station in East China. Our configuration is 200,000 kilowatts and 400,000 kilowatt hours. This means that it can charge 200,000 kilowatt-hours of electricity in one hour, and it can discharge the corresponding amount of electricity when it is fully charged. Shared energy storage stations not only connect to wind power and photovoltaic power stations to store excess power generation during peak power generation periods, but also connect to power-consuming enterprises to provide electric energy to enterprises during peak power consumption periods. Pan Zaibin, director of electrical appliances in the engineering department of a company in Changxing, Zhejiang: Shared energy storage stations have greatly reduced our electricity costs. At present, we only use about 20% to 25%. Wind power and photovoltaic power generation are random and intermittent, and many provinces require power stations to be equipped with energy storage systems for 1 to 2 hours. Industry insiders said that the cost of building energy storage by yourself is high, charging and discharging only once a day, and the use efficiency is low. Shared energy storage power stations are large in scale and connect upstream power stations and downstream power consuming enterprises. They can be charged and discharged multiple times a day, improving usage efficiency. You can also participate in power grid dispatching and earn price differences through peak shaving and valley filling, with low overall costs. By leasing shared energy storage, construction costs of new energy power stations have generally been reduced by more than 10%. Shared energy storage has become very popular and ushered in a construction peak.

On December 2, the four highly conspicuous "gas piers" located at Lu'anzhou Wharf in Changzhou were fully debugged, marking that China's first ultra-large-scale "photovoltaic + gas film" photovoltaic energy power station project will officially receive power. For a long time, large amounts of dust and exhaust gas have been "provoked" during the loading and unloading operations, storage and transportation of coal, sand and gravel and other bulk materials transported at the port. In March this year, the Lu'anzhou Terminal air film greenhouse came into being. It is the first bulk cargo yard in the Yangtze River Basin to use air film technology to achieve fully enclosed operations, and is used to comprehensively improve the ecological environment of the port terminal. These four greenhouses are located in the first and second phase bulk cargo yards of Lu'anzhou Port. They look like four giant loaves, with a total projected area of over 270,000 square meters, and can store 1.5 million tons of ore and other bulk cargoes at a time. The annual power generation can reach 11.56 million kilowatt hours, and it is expected to reduce 9,500 tons of carbon dioxide emissions a year. Not long ago, the giant "Qidundun" was covered with a "blue quilt". These blue blocks sparkling in the sun are distributed photovoltaic power generation solar panels, which can generate 6 million kilowatt hours for the terminal's own use, accounting for 10% of the total annual power generation. 52%, and the remaining power can be sent to the power grid to earn profits. Now that "Qidundun" has officially entered the 2.0 era, it can not only effectively avoid dust problems in open-air operations, but also achieve significant energy saving and emission reduction benefits through photovoltaic power generation. It is the first in the country to create a new application scenario for distributed solar energy power generation, demonstrating the "hard core" responsibility of green wisdom.

Recently, Azerbaijan’s first 308MWp large-scale new energy solar energy power station was officially connected to the grid to generate electricity. After the power station is connected to the grid, its annual power generation capacity will reach 500 million kilowatts, which can meet the electricity needs of 110,000 households. On the occasion of the 10th anniversary of the “One Belt, One Road” initiative, the successful completion of this project is an important milestone in green energy cooperation between China and Azerbaijan, injecting strong impetus into local green and low-carbon development. Azerbaijan is one of the first countries to support the "Belt and Road" initiative and has cooperated with China in many fields such as transportation, logistics, and infrastructure. In the context of global carbon neutrality, Azerbaijan's Ministry of Energy expects to increase the proportion of renewable energy installed capacity to 30% by 2030, and begins to actively seek cooperation with Chinese new energy companies to accelerate economic diversification and reduce oil and natural gas dependence. As Azerbaijan's first large-scale renewable energy power station, the project is located in Gobustan District, about 60 kilometers southwest of Baku, the capital of Azerbaijan, covering an area of approximately 5.5 million square meters. The power station adopts an innovative 8.85MW large sub-array design to further increase power generation, reduce investment costs, and ensure safe and efficient power generation. Azerbaijani President Ilham Aliyev said at the grid connection ceremony: "Last year we participated in the groundbreaking ceremony of this photovoltaic power plant. Today, we are very proud to see that in a short period of time, Gobustan "It's a remarkable achievement to turn this open area into a source of green energy." Over the past decade, Chinese companies have used products, technologies, and services to inject vitality into the energy transformation of many countries and promote local economic growth. As a leading company in renewable energy in China, Sungrow has also contributed to the Belt and Road Initiative by providing cutting-edge renewable energy solutions and services. It is believed that more and more renewable energy projects will be implemented under this initiative in the future, and global carbon neutrality will be on the fast track.

Thanks to PV systems and battery storage, millions of households in Europe are already partially self-sufficient. A German-Swiss research group has calculated the potential for European residential buildings to achieve grid independence with solar-plus-storage solutions. The team aimed to determine whether such homes could abandon the grid completely. They based their calculations on a database that combined detailed geographic data about European buildings and households with local climate and economic factors. Using advanced techniques to simplify the process on high-performance computers, they designed cost-optimized, self-sustaining energy systems for 4,000 representative single-family homes. These results were then applied to the 41 million single-family homes they analyzed using neural networks. “Under today’s conditions, 53% of the 41 million buildings are technically capable of powering themselves through the use of local rooftop PV systems alone, independent of external infrastructure, and this share could rise to 75% by 2050 due to improved technologies,” said researcher Russell McKenna. “If we now assume that building owners would be willing to invest up to 50% more than would be necessary for a comparable energy system with a grid connection, then up to two million single-family homes could leave the grid by 2050.” Energy self-sufficient residential buildings show great potential, particularly in regions with stable weather patterns like Spain and areas with high electricity costs such as Germany. Electrolysis could also be a key component in cost-optimized systems. “Our results show that a successful, cost-optimal and self-sufficient energy supply system for buildings in Central Europe will consist of photovoltaics for electricity generation as well as a combination of short-term battery storage and a long-term battery storage, seasonal hydrogen storage system,” said researcher Jann Weinand. The key question is whether widespread adoption of fully self-sufficient, off-grid supply systems aligns with an efficient energy system. Single-family homes can contribute significantly to stabilizing a renewable-based energy system through load management, on-demand solar power injection, and provision of balancing services.
