6 FAQs about [Polansa inter-seasonal energy storage project]
Can seasonal pumped hydropower storage provide long-term energy storage?
Seasonal pumped hydropower storage (SPHS) can provide long-term energy storage at a relatively low-cost and co-benefits in the form of freshwater storage capacity. We present the first estimate of the global assessment of SPHS potential, using a novel plant-siting methodology based on high-resolution topographical and hydrological data.
Can seasonal energy storage be economically viable?
To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. Storage of this nature is expected to have output durations from 500 to 1000 hours or more.
What is inter-seasonal storage?
More specifically, inter-seasonal storage will probably be composed of a combination of PHS, compressed-air energy storage (CAES) and possibly geological hydrogen storage 8. CAES is currently the only other commercially mature technology for this application 9, and it is therefore crucial to assess its inter-seasonal storage potential.
Is pm-CAES a viable large-scale inter-seasonal electricity storage technology?
Our results show that PM-CAES is a potentially viable large-scale inter-seasonal electricity storage technology, crucial in power systems with over 80% of their generation capacity provided by renewable energy sources. The small surface footprint of PM-CAES would benefit regions with limited land surface or water resources.
How do seasonal energy exchanges affect sea ice retreat?
Using a regional, process-oriented surface energy budget analysis, we argue that differences in seasonal energy exchanges in sea ice retreat regions via increased absorption and storage of sunlight in summer and increased upward surface turbulent fluxes in fall/winter contribute to the inter-model spread.
Is PHS a seasonal energy and water storage alternative?
Given the current costs reduction in other technologies offering daily energy storage (particularly batteries), PHS is anticipated to gain importance as a seasonal energy and water storage alternative. A SPHS plant consists of a high-head variation storage reservoir built in parallel to a major river.
