Where are the lead-acid batteries in Latin America?

Though lithium-ion batteries are by far the dominant battery technology for energy storage in LAC, this study identified seven planned or operational lead-acid battery projects. Six of these are mini- grid projects paired with solar PV, located in Guyana, Chile, Costa Rica, and Colombia, as well as IDB projects in Bolivia and Suriname.

Is pumped hydro the future of energy storage in Latin America?

Pumped hydro is the most widespread form of energy storage worldwide, but despite the abundance of hydroelectric power in use in Latin America, this technology has not been deployed in most of the region. Argentina is an exception, home to two pumped hydro storage facilities with combined capacity of almost 1 GW since the 1980s.

Can unrepresented dynamics lead to suboptimal control of battery energy storage systems?

Unrepresented dynamics in these models can lead to suboptimal control. Our goal is to examine the state-of-the-art with respect to the models used in optimal control of battery energy storage systems (BESSs). This review helps engineers navigate the range of available design choices and helps researchers by identifying gaps in the state-of-the-art.

Which energy storage technologies will be used in the future?

Other technologies, such as molten salt thermal energy storage paired with concentrated solar power generation, or compressed air energy storage, could be deployed in specific contexts. Hydrogen storage is likely poised for a larger role down the line as the technology matures. Figure 1: Annual Energy Storage Deployment, 2016-2019 (GW)

How do we model battery degradation?

Modeling battery degradation can be done empirically or based on underlying physical mechanisms. Empirical stress factor models isolate the impacts of time, current, SoC, temperature, and depth-of-discharge (DoD) on battery state-of-health (SoH).

What can we learn from energy storage in Lac?

A heightened understanding of energy storage and its applications in LAC will serve as a first step for governments to consider their options as they seek to decarbonize and improve the performance of their grids. This knowledge will also be important for the development of regulation that facilitates the uptake of energy storage in the region.
