6 FAQs about [Water supply and energy storage]

Why is water storage important?

Storing water will be vital to adapt to climate change, according to a new World Bank report. The world faces a water storage gap as demand for fresh water grows and glaciers, snowpack, and wetlands decline. A new approach that integrates built and natural water storage is needed to holistically manage water throughout entire water systems.

Can water reservoirs be used as energy storage devices?

Investigations showed that implementing energy storage systems allows more integration of renewables into water systems, but the potential of using water reservoirs as energy storage devices will provide new perspectives in this field.

Why is freshwater storage important?

Freshwater storage is at the heart of adapting to climate change, most obviously by saving water for drier times and reducing the impact of floods. Water is at the center of economic and social development; it influences whether communities are healthy places to live, good places to grow food, or have reliable clean energy.

Can surplus wind and solar energy be stored in a water reservoir?

To conclude, most water systems have a reservoir installed in an elevated position, which can be potentially considered as a reservoir for small-scale pumped storage units. Therefore, it is suggested to explore the optimal scheduling of surplus wind and solar energy, with the capability of storing them in a water reservoir, as a research avenue. 8.
