“…We did perform a few simulations using hydrogen storage for comparison; however, the cost of hydrogen storage was significantly higher than that of pumped hydro storage. In large part this seems to be due to the fact that fuel cells and electrolyzers currently cost much more than pumps and turbines with the same power rating [ 50 – 55 ]. Fuel cells and electrolyzers also generally have lower efficiencies than pumped hydro storage, which would also cause hydrogen storage to have a comparatively higher cost [ 52 , 56 ].…”

“…Energiasalv has estimated that their proposed underground storage facility in Paldiski, Estonia would take 8 years to construct and have a lifespan of 60 years, so we used those parameters for our calculations [ 45 ]. We took estimates for the capital costs of the reservoirs, pumps, turbines, and other equipment from Kapila et al [ 55 ] and Guo et al [ 50 ]. Estimates from Guo et al [ 50 ] indicate that underground pumped hydro storage is roughly twice as expensive as conventional aboveground configurations, and this difference was taken into account when estimating the cost.…”

Comparison of the most likely low-emission electricity production systems in Estonia

To meet targets for reducing greenhouse gas emissions, many countries, including Estonia, must transition to low-emission electricity sources. Based on current circumstances, the most likely options in Estonia are renewables with energy storage, oil shale power plants with carbon capture and storage (CCS), or the combination of renewables and either oil shale or nuclear power plants. Here we compare these different scenarios to help determine which would be the most promising based on current information. For the comparison we performed simulations to assess how various systems meet the electricity demand in Estonia and at what cost. Based on our simulation results and literature data, combining wind turbines with thermal power plants would provide grid stability at a more affordable cost. Using nuclear power to compliment wind turbines would lead to an overall levelized cost of electricity (LCOE) in the range of 68 to 150 EUR/MWh (median of 103 EUR/MWh). Using oil shale power plants with CCS would give a cost between 91 and 163 EUR/MWh (median of 118 EUR/MWh). By comparison, using only renewables and energy storage would have an LCOE of 106 to 241 EUR/MWh (median of 153 EUR/MWh).

“…Other direct/physical environmental impacts of hydropower plants are loss of historical remains and terrestrial fauna and flora, including rare, endemic, localized, threatened or endangered species [67], visual pollution [71]. Indirect impacts of hydropower plants/PHSP can be assessed by the use of methods such as life cycle assessment (LCA), which was applied by Guo et al [81] to evaluate conventional and underground PHSPs.…”

Pumped hydro storage plants (PHSP) are considered the most mature large-scale energy storage technology. Although Brazil stands out worldwide in terms of hydroelectric power generation, the use of PHSP in the country is practically nonexistent. Considering the advancement of variable renewable sources in the Brazilian electrical mix, and the need to provide flexibility to the national electrical system, several official documents cite PHSP as an important alternative for the expansion of the Brazilian electrical system. This article presents the state of the art of PHSP and its use, in order to create a theoretical basis for future research on the subject, also providing theoretical support for Brazilian energy planning. The review includes a global panorama on the use of PHSP in the world, the technical and projective foundations on this type of technology, its benefits, and disadvantages, in addition to the new configurations and possible layouts for the construction of pumped hydro storage plants. Finally, the challenges and trends for the dissemination of PHSP technology are addressed.
