on march 28, the boao forum for asia annual conference 2023 kicked off on dongyu island in boao, hainan province. the vanadium flow battery energy storage system developed by the national institute of clean-and-low-carbon energy (nice) under chn energy debuted in boao to serve the event. to better spread the vanadium flow battery energy storage technology, nice developed the vanadium flow battery energy storage module to connect into the energy system of the boao forum for asia’s media center, achieving in-situ consumption and absorption of new energy-based green electricity. it ensured the boao forum for asia’s media center to be close to the zero-load state in both peak and slack periods, facilitating the smooth convening of the boao forum for asia annual conference.
on march 24, 2023, the 30mw rooftop photovoltaic power station project in tangshan zhengfeng iron & steel co., ltd. of new energy company of chn energy hebei branch officially began commercial operation. following an operation mode of “generating power for self-use and transferring extra electricity to the grid”, the project can generate electricity of 33,174,000 kwh, save 10,114.64 tons of standard coal and reduce carbon dioxide emissions by 27,600.47 tons, sulfur dioxide emissions by 5.31 tons, nitrogen oxide emissions by 5.9s4 tons and dust emissions by 1.06 tons each year, thus creating remarkable economical, environmental and social benefits.
lately, china longyuan power group co., ltd. (“longyuan power” for short) under chn energy put into operation china’s first meteorological atlas that it developed for domestic new energy operators, achieving integrated display of meteorological historical data and forecast data and initiating the long-term meteorological forecast technology. the historical atlas of the system covers the whole world and can display monthly and yearly meteorological data over the past 30 years; and the forecast atlas covers the entire country and can display short-term, mid-term and long-term meteorological data.
on march 7, 2023, the "development and application of full load denitration technology for thermal power plants based on water side regulation" of jiangsu taicang branch of china energy was awarded the second prize of 2022 electric power technology innovation award. after the application of full load denitration technology, the company’s number of hours of nitrogen oxide exceeding the standard after each startup and grid connection has dropped from three to zero, and its annual emission of nitrogen oxide has been reduced by 15 tons, thus meeting the emission standards of full load nitrogen oxide and making a positive contribution to local emission reduction and winning the blue sky defense war.
as of march 7, 2023, the "automatic spray of super large mining height gangway" of shangwan mine of shendong coal, a subsidiary of china energy, had been in use for one month, reducing the dust concentration of the working face by 70% and ensuring the safety of on-site operations to the maximum extent, which is of milestone significance to dust-free mine construction.
on february 24, the “design and development of in-situ self-healing anti-toxic catalyst and its application in the field of energy catalysis” project launched by the national institute of clean-and-low-carbon energy (nice) under chn energy won the excellent project award at the finals of the 2022 national disruptive technology innovation contest. catalysts with crystal defects can not only significantly reduce costs, but also may eradicate the problem of catalyst poisoning. moreover, they can not only achieve catalytic elimination and efficient emission reduction of nitrogen oxides, volatile organic compounds, methane, etc., but also have the potential to be applied in energy and chemical fields such as energy storage, green ammonia synthesis, and ammonia oxidation. a paper on the latest findings of the project was recently published in ees catalysis (energy and environmental science – catalysis), an authoritative journal on energy and environmental protection, as a cover article.
on february 24, the 100mw/200mw energy storage station of ningdong photovoltaic base under ningxia power co., ltd. (“ningxia power” for short), a subsidiary of chn energy, was connected to the grid. the energy storage station is a supporting facility for ningxia power’s 2mw integrated photovoltaic base, one of china’s first large-scale wind-photovoltaic power base projects. it has a planned total capacity of 200mw/400mw, and the completed phase of the project has a capacity of 100mw/200mw. the energy storage station adopts safe, reliable lithium iron phosphate battery cells for energy storage with great consistency, high conversion rate and long cycle life, as well as a non-walk-in liquid-cooled containerized energy storage system.
on january 30, 2023, gd power shanghaimiao company, a subsidiary of chn energy, received the award of the xinhua credit jinlan cup technology innovation case for carbon peaking and carbon neutrality for its project "china’s first 1gw thermal power ultra large all steel structure indirect air cooling tower". compared with traditional concrete intercooling towers, this innovative project has the advantages of frost resistance, good seismic performance, and convenient installation. it meets the national energy conservation requirements and environmental protection policies. it can save a large amount of cement, sand, and stone, without generating construction waste. in addition, when the steel structure cooling tower reaches its service life and is retired, the main steel components can still be recycled—a prominent advantage in ensuring safe and high-quality construction and green transformation of the project.
