Could water be a solution to problems of renewable energy storage?

According to previously issued research in Nature Communications journal, recurrently used technology known as Seasonally Pumped Hydropower Storage (SPHS) could be a solution to enable the storage of water on a yearly measurement since it is cheap and readily available. According to the research, there is an excellent ability for SPHS to distribute highly competent energy prices as opposed to natural gas.

Several countries’ energy departments are adjusting swiftly to the wind and solar energy productions. Those energy sources require storage replacements since they have discontinuous and seasonal differences. It will aid them in having in mind that there is the attainment of demand at a given period. 

Periodic harnessed hydroelectric power storage refers to thrusting water into an underground room connected parallel to Main River when there are high and frequent rains. When there are scarcity and increased demands of water, they will release stored water from the reservoir and help in generating electricity.

The above recent research is the first one to give comprehensive solutions to the cost of SPHS technology. In their findings, researchers assessed the presence of abilities to store water with SPHS periodically. They had in mind all regions that will have the highest and lowest number of costs. They analyzed diverse occasions where water and electricity with SPHS could exist in an alternative form. Factors listed in their researches constitute scenery, the connection of rivers, hydrological analysis, expenses on the infrastructure, scheme designs, and available candidate areas.

Results from their researches show that there is a significant ability that is available around the SPHS, especially the lower region of Himalayas, Andes, Alps, Rocky Mountains, Ethiopian Highlands, and Brazilian Highlands among many other areas.

There is an endorsement concerning the intermittency and period ability of wind and solar. The research illustrates that there are extremely high chances of nations embracing SPHS across the globe provided there are accessible, affordable, and sustainable energy structures that will lead them to surpass the actual obstacles in gaining high shares of the renewable era.   

Another aspect addressed in the research is environmental conservation related to hydropower since basins of SPHS are deep and made adjacent to each other instead of constructing them in the middle of rivers. The impacts posed to the environment could total to 10%, which is a smaller figure of influence as opposed to fossil fuel plants. 

Since there is a high urge to transform the world to fewer carbon dioxide productions, renewable energies and storage have to do their part in the coming days since SPHS can store energy and water on an annual basis.
