Can energy storage batteries replace capacity expansion

Why do we need battery energy storage systems?

Battery energy storage systems (BESS) have become a solution to prevent surpluses from being lost and to cover the intermittence of renewable energy. “We need energy storage solutions to make them permanent,” says researcher and electric battery expert Philippe Knauth in an interview for bbva.com.

How much battery storage is needed to achieve energy transition goals?

In fact, at least 1200 GW of battery storage capacity will be needed if the world wants to achieve 2030 energy transition goals. While Pumped storage hydropower (PSH) is a traditional storage method that accounts for a majority of global storage still, it faces challenges which make alternative storage solutions a more attractive option.

Can battery storage support electricity security cost-effectively?

The report highlights the versatility of battery storage to support electricity security cost-effectively as part of clean energy transitions. In the power sector, batteries help smooth out the variability of renewable electricity from technologies such as wind and solar.

What if we don't have enough batteries?

To triple global renewable energy capacity by 2030, 1 500 GW of energy storage, of which 1 200 GW from batteries, will be required. A shortfall in deploying enough batteries would risk stalling clean energy transitions in the power sector.

Can energy storage be expanded across different thermal power units?

With a step length of 500 MW, capacity expansion planning for energy storage is conducted across varying thermal power capacities. The results are shown in Fig. 10. Fig. 10. Planning results of energy storage under different thermal power unit capacities.

Can China provide battery energy storage solutions to global renewable capacity?

In a race of providing battery energy storage solutions to global renewable capacity, China is leading with about 60 percent of the global manufacturing capacity of lithium-ion batteries and more than 90 percent of the processing capability of raw metals and minerals, a potential to provide for the 2024 global energy storage needs all by itself.
