Batteries are rapidly falling in price and can compete with pumped hydro for short-term storage (minutes to hours). However, pumped hydro continues to be much cheaper for large-scale energy storage (several hours to weeks). Most existing pumped hydro storage is river-based in conjunction with hydroelectric generation.
At the same time, it is emphasised that this power is not renewable. Thus, the question arises as to why it has been proposed in Table 10 a/b to include non-renewable energy. Of course, pumped storage is the most mature technology to store electricity
