1. Introduction. The European Commission has developed the Renewable Energy Directive to reduce climate change processes. The directive sets a target of 55% reduction in greenhouse gas emissions by 2030 [1] and pushes Europe to be the first climate-neutral region by 2050. Based on the assessment of the 2030 Climate Target
Comparison of underwater with conventional pumped hydro-energy storage
The power of a turbine is proportional to the speed υ of water falling onto the turbine, (3) P = m ˙ g H, with mass flow rate (4) m ˙ = ρ V ˙ = ρ A υ for a water flux through area A, which brings us back to Eqs. 1 and 2.Therefore both PHS systems, offshore and onshore, have the same energy storage capacity. The only advantage of
