Can pumped storage hydropower boost China's green energy transition?

Increasing pumped storage hydropower capacity is vital for promoting the green energy transition in China, responding to extreme situations and ensuring energy security, said Peng Caide, chief engineer with the China Renewable Energy Engineering Institute, a think tank under China's National Energy Administration.

What is Bloom Energy & how does it work?

These startups develop new energy storage technologies such as advanced lithium-ion batteries, gravity storage, compressed air energy storage (CAES), hydrogen storage, etc Bloom Energy offers on-site power generation systems that can use a wide variety of inputs to generate electricity.

Is China a leader in pumped storage technology?

China has emerged as a global leader in pumped storage technology, which is the most mature solution for large-scale, long-duration energy storage. By the end of 2024, the State Grid Corporation of China had 40.56 GW of operational pumped storage capacity, with an additional 53.48 GW under construction.

Why is Fengning the most significant pumped storage facility in North China?

When fully charged, the upper reservoir can store enough energy to power the plant at full capacity for 10.8 hours, equivalent to nearly 40 GWh. This makes Fengning the most significant pumped storage facility in North China in terms of balancing renewable energy output.

Will pumped storage hydropower be a big deal in 2035?

Renewable energy accounts for an ever-increasing share of the market, and it is expected the maximum peak-valley difference of the power system will exceed 1 billion kilowatts by 2035. A new electrical power system with new energy as the mainstay of the power system, in turn, will have higher criteria for pumped storage hydropower, he added.

What is the future of power storage?

"With increasing use of wind and solar power, the market prospect of power storage is very promising," Peng said. Renewable energy accounts for an ever-increasing share of the market, and it is expected the maximum peak-valley difference of the power system will exceed 1 billion kilowatts by 2035.
