pumped-hydro energy storage

Pumped hydro energy storage is ideally positioned to support reliability and reduce volatility in the energy market as Australia shifts from fossil fuels towards renewable power with former prime minister Malcolm Turnbull labeling the technology the “ultimate long-duration storage” solution.

Jamaica’s prime minister Andrew Holness revealed that an international consortium is planning to build a pumped-hydro storage project that has already secured preliminary approval. The project, which will also include deep-sea desalination, is currently undergoing technical and due-diligence reviews.

Greenko Group has agreed to provide Ayana with 6GWh of pumped-hydro storage capacity from its project in the Indian state of Andhra Pradesh.

The Spanish energy company is building a huge hydropower complex across three water reservoirs in northern Portugal. The project will rely on 880 MW of pumped-hydro storage and is expected to become fully operational in 2024.

Genex Power says it is now ahead of schedule on the construction of a new engineering project to transform a retired gold mine site in Australia into a 250MW/2GWh pumped hydro energy storage facility.

Located in China’s Hebei province, the 3.6GW facility consists of 12 reversible pump generating sets with a capacity of 300MW each and has a power generation capacity from storage of 6.612 billion kWh.

According to Chinese researchers, using abandoned coal mine goaves for pumped hydro facilities in combination with large scale solar and wind is not only technically feasible but can also provide an efficiency of 82.8% in yearly operation cases. They applied the model to wind and solar-rich northwestern and southwestern China.

Proposed by Egyptian scientists, the proposed GIS technique considers a pumped-hydro project’s head and elevation difference, the penstock-length distance from the base plant, the site’s slopes and slope of the ground surface, the distance to the national grid and road networks, and the soil suitability. It also takes into account constraints such as land use and restrictions.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

The World Bank has agreed to finance part of a project owned by Indonesian state-owned utility, PLN. The facility is planned to enable a larger penetration of renewable energy to provide with power two large demand centers in West Java.
