If its not solved, which is not, its unsolved. If it was solved no V2G, for example, would be considered. That there are numerous technologies already does not mean its solved, let alone profitable.

The research question asks whether it is profitable to invest in increased
pumped hydro storage capacity in Norway to exploit Germany’s increasing
need to balance their expanding share of intermittent renewable electricity
generation. Based on the results and the discussion there are no findings
directly supporting profitability.


PHS is a high capacity storage alternative with low energy losses compared to
other technologies. Unfortunately, the implementation time is lengthy, and
there are some environmental concerns, which reduces the public
acceptance. Furthermore, the power-intensive industries are also wary of the
impact of PHS. Another concern is the future variability of prices due to
different levels of installed renewable power. The implementation of solar
power has reduced the price differences between day and night, implying
less attractive investment opportunities for flexible power productions,
including PHS.

So now we gonna Google articles supporting our opinion, right? And do you know what we gonna end up with? With definition of "(un)solved".

If its solved, lets build pump storage and move onto other problems to solve. Thanks for reading.
