Electricity Storage Technology Review
Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
Time Synchronization
when its clock is t1, and p2 receives m when its clock is t2. We know that t1 and t2 occur at nearly the same real time. Therefore, the di erence between p1 and p2''s clocks is t2 t1. So, when p1''s clock says x, p2''s clock says x+t2 t1. Thus, p1 has a way to2
