at the 2024 services trade fair held recently, the capital green development and innovation practice exhibition area hosted by the beijing development and reform commission and the beijing energy conservation and environmental protection center attracted many visitors. sandbox, real objects, models, videos, exhibition boards... various digital display technologies and interactive experience display methods were combined to present the outstanding achievements and innovative practices of the beijing energy conservation and environmental protection center in supporting and promoting the comprehensive green transformation of the capital's economic and social development in an all-round and three-dimensional manner.
30,000 households installed photovoltaic power generation systems
in recent years, beijing has vigorously developed new energy and renewable energy, and the energy transformation work has been moving forward "green", showing a good trend of both supply and demand. according to the relevant person in charge of the beijing energy conservation and environmental protection center, on the supply side, a number of new energy and renewable energy projects such as wind power, photovoltaic, and biomass power generation have been built and put into operation. as of the first half of this year, more than 1,000 enterprises and institutions and 30,000 households have installed photovoltaic power generation systems. the installed capacity of new energy and renewable energy in beijing has increased by 101.2% compared with 2015, accounting for 20.8% of the total installed power generation capacity. beijing has also continuously expanded the "circle of friends" of green electricity sources to enrich the sources of green electricity and ensure the supply of green electricity. on the consumer side, beijing's green electricity consumption in the first half of this year increased by 17.9% compared with the same period last year. the scale of market-based green electricity transactions in the first half of the year reached 4.05 billion kwh, 7.5 times that of the same period last year. many typical application scenarios such as the administrative office area of the sub-center of the city, the state grid future science city park, and the self-operated charging piles of the bus group have achieved full green electricity application.
green ecological restoration is a prominent feature of the "urban green heart". it is understood that the "urban green heart" covers a total area of about 11.2 square kilometers. it was built on the original site of the oriental chemical plant in 1978. after the withdrawal of the oriental chemical plant, the regional ecological foundation was very weak. beijing launched the ecological governance of the area in 2016. through the construction of the "3+1" green ecological environment management and control system of ecological isolation, ecological restoration, dynamic assessment and emergency response, a strong ecological security firewall was built. now it has become the "urban green lung" - beijing urban green heart forest park. the forest coverage rate here is as high as more than 80%, with more than 200 species of plants. more than 60 species of wild animals have settled in the ecological conservation core. the "urban green heart" has become the "ecological business card" of the city's sub-center.
at the same time, beijing vigorously promotes green buildings. the three major cultural facilities in the sub-center of the city - beijing art center, beijing city library, and beijing grand canal museum - have a total construction area of 300,000 square meters, all of which meet the three-star green building standard. it is worth mentioning that the three major cultural facilities all use a composite solution of "ground source heat pump + water storage + chiller + gas boiler" for cooling and heating. in addition, the park also installs rooftop photovoltaic and energy storage facilities, creates a smart distribution network, and pilots green electricity and green certificate trading to achieve the comprehensive utilization and promotion of green energy.

"new energy vehicle comprehensive service" showcases new scenarios for the application of photovoltaic storage, charging and battery replacement in beijing. this reporter saw that the new application scenario showcases the integrated application of "photovoltaic, energy storage, charging and battery replacement", which can provide one-stop supercharging, fast charging and battery replacement services for various types of new energy vehicle users, and combine photovoltaic power generation and energy storage facilities to greatly enhance the ability of comprehensive services for new energy vehicles and effectively reduce operating costs. according to the relevant person in charge of the beijing energy conservation and environmental protection center, the application scenario was officially put into operation at the capital airport energy center in august 2023, with a planned area of over 10,000 square meters, only 2 kilometers away from the capital airport t3 terminal and a 5-minute drive. the 160 charging parking spaces and 2 battery replacement stations set up can provide supercharging, fast charging and battery replacement services for more than 3,200 new energy vehicle users such as buses, logistics vehicles, engineering vehicles, and passenger cars every day. the 800-kilowatt photovoltaic power generation equipment built has an annual power generation of over 1 million kwh, which can effectively improve service capabilities when combined with the 400 kwh/1000 kwh energy storage facilities equipped.
the super liquid-cooled charging pile demonstrated a new breakthrough of 90% fast charging in 10 minutes. in this exhibition area, a technologically advanced super liquid-cooled charging pile was surrounded by spectators. according to the above-mentioned person in charge, the maximum output power of a single gun of this super liquid-cooled charging pile can reach 600 kilowatts, and the maximum output current is 600 amperes. it can charge 90% of a new energy car with a standard range of 70 kwh in 10 minutes, bringing users an ultimate charging experience of "about one kilometer per second" that is similar to refueling. it uses liquid cooling to dissipate heat, which can increase the life of the charging pile by more than 5 years, and is equipped with a 15-inch high-definition touch screen, which can bring a good user experience.
a total of 142 innovative green technologies have been recommended
the green technology system supports a new leap in the greening of data centers. data centers are an important carrier to support the development of the digital economy and an important tool for energy conservation and carbon reduction. in the green data center exhibition area, the green technology system architecture diagram of the data center, which consists of 10 advanced technologies such as immersion liquid cooling, intelligent micro-modules, digital intelligent management and control, and integrated power modules, is presented in front of us. this technology system can effectively support the rapid development of greening in the current data center field. the intelligent micro-modules displayed on site have the advantages of integrated integration, rapid deployment, space saving, energy saving, and an average annual pue of 1.11. the fully immersed phase change liquid cooling server is suitable for high power density data centers, has efficient heat exchange capabilities, and the lowest pue can reach 1.04, and can bring a new visual experience.
in the green technology exhibition area, our reporter saw the new progress in the promotion of innovative green technologies and energy-saving technology products organized by beijing since 2020 to promote the innovation and application of green technologies and guide energy-consuming units to adopt advanced and applicable new technologies, new equipment and new processes. so far, beijing has recommended a total of 142 innovative green technologies and 244 energy-saving technology products, and released 19 typical cases of green and low-carbon technologies in beijing, tianjin and hebei for the first time on the occasion of the 10th anniversary of the coordinated development of beijing, tianjin and hebei. for example, carbon dioxide transcritical refrigeration technology is more environmentally friendly than traditional technology, and its energy efficiency is improved by more than 20%. this technology is applied to the beijing winter olympics speed skating oval. the temperature difference of the ice surface is controlled at 0.5°c. the ice surface is flat, smooth, and the temperature conduction is uniform, making it the world's first winter olympics speed skating venue to use carbon dioxide transcritical direct evaporation refrigeration; for example, aiot intelligent building management and control technology realizes deep data sharing and interaction through customized integrated subsystems such as the energy management internet of things, equipment monitoring and early warning, and conducts energy carbon emission quota management, intelligent diagnosis and strategy optimization to serve building energy management. the comprehensive energy saving rate can reach 15%~20%. this technology has been effectively used in the national stadium.
6.7 million citizens have established a “personal carbon ledger”
the touch screen of the "beijing green life platform" attracted many viewers to try and experience it. it is reported that citizens can scan the qr code on their mobile phones to establish their own carbon ledgers, automatically record the carbon reduction of green transportation, green catering, garbage classification and other practices of green and low-carbon life into the "personal carbon ledger", and obtain corresponding green points incentives. they can also exchange for cycling cards, coupons, vouchers, etc. provided by platforms such as meituan, ele.me, and kuaidian through the points consumption channel, and use visible and tangible incentives to guide citizens to practice green and low-carbon life. in the three years since the beijing energy conservation and environmental protection center innovatively launched the "beijing green life season", it has established "personal carbon ledgers" for 6.7 million citizens through the "beijing green life platform", and has driven more than 400 million citizens to practice a green lifestyle, effectively promoting the green transformation of citizens' lifestyles. in addition, the "beijing green life season" also helped the 2023 beijing urban sub-center green development forum, the 2024 beijing cbd international forum, and the 2024 national ecological day beijing promotion activities to achieve "carbon neutrality".
green production showcases new achievements in the coordinated development of beijing, tianjin and hebei. in the green production section, beijing actively implements the coordinated development strategy of beijing, tianjin and hebei, innovatively implements the "beijing-tianjin-hebei clean production partnership program", and promotes the implementation of clean production in key units with "headquarters in beijing and production plants in tianjin and hebei". beijing takes advantage of overall coordination and funds to actively explore collaborative innovation in clean production in beijing, tianjin and hebei. for example, by the end of 2023, beijing jinyu mortar will complete the clean production transformation of its four production bases in doudian, fangshan, mafang, pinggu, chengde, hebei, and guantao, handan in the beijing-tianjin-hebei region, with a subsidy of 4.12 million yuan, annual energy saving of 931.63 tons of standard coal, reduction of 2,288.05 tons of carbon dioxide emissions, reduction of 100.30 tons of particulate matter, and reduction of 8.92 tons of nitrogen oxides. in august 2023, the beijing-tianjin-hebei regional clean production collaborative audit innovation pilot project was approved by the ministry of ecology and environment and the national development and reform commission, becoming the only cross-regional project in the second batch of national clean production audit innovation pilots. in 2024, the beijing-tianjin-hebei regional clean production audit innovation project will focus on the coordinated governance of air pollution in the beijing-tianjin-hebei region, while supporting the integrated green development of beijing's sub-center and the northern three counties of langfang. it will select four industries, namely medicine, energy, printing, and building materials, and initiate 60 pilot enterprises to jointly promote clean production audits, innovate regional clean production collaborative audit mechanisms, methods and procedures, and resource sharing paths, and help the green and low-carbon transformation and development of the beijing-tianjin-hebei region.
