China brings on stream world’s largest pumped storage hydro station

The State Grid Corporation of China (SGCC) has brought on stream the first of two phases of the Fengning pumped storage hydropower station in Hebei province in the east of the country. The second phase is due to come into operation in 2023.

The combined installed capacity of the hydro generators at that time will reach 3.6 gigawatts (GW), the SGCC announced on the Greater Bay Area (GBA) portal.

     Once operating at full capacity, the Fengning station can generate 6.6 terawatt hours (TWh) of power annually – comparable to the annual output of Latvia (5.7 TWh), according to figures from BP’s 2020 Statistical Review of World Energy.

    The station is connected to two ultra-high voltage (500 KW) grids covering Beijing, Tianjing (continental China’s third largest city in terms of area) and the northern part of Hebei Province. The availability of accumulated capacity should allow for a balancing of risks of temporary reductions in generation from local wind farms and solar panels as well as allowing for a reduced carbon footprint.

    “(The station) can help save 480,000 tonnes of coal and reduce 1.2 million tonnes of carbon dioxide emissions every year,” the GBA portal quoted Wu Peizhi, deputy general manager of the power station, as saying. “It will help make the Olympics 100-percent the greenest ever in history.”  

    Hydropower accounted for 17 % of China’s overall generating output in 2020, according to the BP Statistical Review. The share attributed to all renewable energy sources stood at 11 % – China is the world leader in terms of growth of installed capacity of wind farms and solar panels.

1650 hydrogen molecules per hour

The Novosibirsk scientists have proposed a new efficient method for synthesis of a highly active photocatalyst for hydrogen production under the action of sunlight. The materials developed are porous “sponges” made of graphite-like carbon nitride with platinum nanoparticles. The system showed one of the highest values of photocatalytic activity, among all known analogues, with a low content of noble metals, the Russian Science Foundation says.

Metal-organic frameworks for CO2 capture

British renewable energy company Drax along with Promethean Particles, a metal-organic framework manufacturer and the University of Nottingham is going to test an innovative CO2 capture unit at the bioenergy power plant in North Yorkshire. If the tests are a success, Drax will launch construction of a full-fledged commercial analogue in 2024, its first stage will be put into operation in 2027, and the second one – in 2030.

Rae Kwon Chung: the new climate economy can be a job generator

Transition to a sustainable economic development model focused on investment in the planet’s resources and human capital increase will lead to rapid generation of new jobs. Rae Kwon Chung, Chairman of the International Award Committee of the Global Energy Prize, talked about this in the lecture The New Climate Economy and Carbon Neutrality on May 19 as part of the New Horizons online forum arranged by the Russian Znanie Society.
