What are energy storage technologies?

Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance. Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time.

Are battery electricity storage systems a good investment?

This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.

How are power station equipment costs determined?

As described above, power station equipment costs are determined with the method described in Section 4.3. Depending on the type of power station (underground or surface) the total cost of power station equipment is estimated using head height and power plant capacity to reflect economies of scale.

Can energy storage improve solar and wind power?

With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.

Will additional storage technologies be added?

Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).

What is PSH generating capacity?

PSH is a mature technology that was deployed widely after the Second World War. Current global installed PSH generating capacity is around 160 GW with about 9,000 gigawatt-hours (GWh) of energy storage (Rogner and Troja 2018).
