The State of Qatar has begun a pilot project to store grid-scale power using a 1MW/4MWh lithium-ion energy storage system— a first for the state that relies completely on power from gas and oil.
[pdf] Transnistria's storage systems combine lithium-ion batteries with something you wouldn't expect - repurposed electric vehicle (EV) batteries from Western Europe. Wait, no. actually, they're using new LiFePO4 (lithium iron phosphate) cells specifically designed for stationary storage.
[pdf] Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine.
[pdf] Standard options, typically found on the market, range in height from 1 meter to over 3 meters. Width can swing from 0.5 meters to 1.5 meters, and depths of about 0.8 meters to 1.2 meters are common.
[pdf] The industrial park's dynamic energy storage systems act like a giant battery charger for the national grid, storing surplus wind energy during off-peak hours (when electricity prices drop to $18/MWh) and discharging during peak demand (when prices spike to $142/MWh).
[pdf] Construction of the Guishan Offshore Windfarm began in September 2016 by the facility's owner, Southern Offshore Wind Power Joint Development shortly after the approval of the project by the Guangdong Development & Reform Commission. By March 2018, the wind farm is already 75 percent complete and the facility already began generating electricity on March 13, 2018.
