China''s hydro energy storage projections are expected to be significantly expanded as a result of a national construction company unveiling plans for constructing 200 hydro stations in the country, which will be operational by 2025, according to Bloomberg.
China must aggressively work to cut its dependence on fossil fuels for its power needs in the near future. However, renewable energy sources have their potential limitations, and these limitations can be devastating for the country with the highest power demand in the world.
China is also looking for energy storage solutions that will help it cope with energy shortages when the wind is not blowing or the sun isn''t shining on the solar panels in the country. According to the Bloomberg study, China is also investing heavily in battery storage, with about 100GW of storage capacity expected by 2030. Additionally, China is adamantly savvy to tap into the value of hydro energy storage.
What is Hydro Energy Storage?
In times of low power demand and high power availability, hydro energy storage, also known as pumped storage hydropower, uses energy from renewable sources to transport water to a high lever reservoir. When renewable power capacity decreases, but demand increases, the stored water is released and passed through turbines to generate power.
The concept isn''t new and it was used in Italy and Switzerland as early as the 1890s, according to the Energy.gov website. It has been used in the 1930s and elsewhere in the world. As of 2019, the global hydro energy storage capacity lag at 158 GW.
China''''s plans with hydro energy storage
China has always wanted to utilize hydro energy storage. According to Bloomberg, the National Energy Administration (NEA) of China has pushed the country''s hydro energy storage potential at an all-time high of 680 GW. Later in the year, an NEA document said the establishment of 120 GW of storage capacity.
In its 14th five-year program for energy development, which was released just three months ago, Chinese officials anticipate 62 percent of hydrogen energy storage to be operational by 2025, with work underway for another 60 percent by that time.
China''s Power Construction Corporation hopes to build a combined capacity of 270 GW by 2025, doubling the number of people employing them for the five years they had originally set. This would also cover as much as 23 percent of Japan''s peak demand.
China''s intentions to go carbon neutral by 2060 are clearly a shot in the arm, but it opens the way for the country to strengthen its efforts to build solar and wind power facilities to its energy requirements, such as the 450 GW power generation capacity in the Gobi desert.
