Africa presents an immense opportunity for energy storage because it suffers from insufficient energy
Energy storage, especially of electrical energy, has become one of the most dynamic technology sectors and is now universally recognised for its ability to fundamentally improve everyday life.
In particular, the scale-up of batteries, from portable electronics to electric vehicles and now to very large, or utility-scale applications, has empowered both consumers and companies. Today, for the first time in history, every company has a choice to proactively control its energy use rather than remain at the mercy of energy markets or supplying utilities.
What is it and why is it important?
Energy storage is a process by which energy created at one time is preserved for use at another time. While there are many types of energy storage, such as the increase in the potential energy after lifting a mass or the potential energy for heat trapped inside a piece of wood or coal. Electricity by its very nature cannot be stored in the form of electricity, however, it can be converted into another form of energy and stored for later use.
Many different processes exist to convert electrical energy into other forms of energy, including mechanical, thermal, electrical, chemical, etc. The latter is the most common in electronics and automobile applications. This process is now increasingly being deployed through novel technologies in much larger, utility scale applications as wel
What are the applications of utility scale energy storagefor Africa ?
There are many important applications for energy storage
Off-to-on peak intermittent shifting and firming
Charge at the site of off peak renewable and/ or intermittent energy sources; discharge energy into the grid during on peak periods
On-peak intermittent energy smoothing and shaping
Charge/discharge in seconds to minutes to smooth intermittent generation and/or charge/discharge in minutes to hours to shape energy profile
Use an energy storage device to defer upgrades in transmission
Use an energy storage device to defer upgrades in distribution
Transportable distribution level outage mitigation
Use a transportable storage unit to provide supplemental power to end users during outages due to short term distribution overload situations
Peak load shifting downstream of distribution system
Charge device during off peak downstream of the distribution system (below secondary transformer); discharge during 2-4 hour daily peek
End-user time of-use rate optimisation
Charge device when retail time-of-use (TOU) prices are low and discharge, when prices are high
Micro grid formation
Energy storage is deployed in conjunction with local generation to separate from the grid, creating an islanded micro-grid
Uninterruptible power supply
End user deploys energy storage to improve power quality and /or provide backup power during outages
Energy storage applications vary by their power requirement and discharge duration

Why are batteries the most flexible type of utility scale energy storage?
Batteries are the most flexible type of energy storage (see chart below) because they can be placed almost anywhere without special geographical or topographical requirements. This “distributed nature” allows them to be integrated into the grid or used off-grid.”. Furthermore, batteries are modular, meaning that energy storage amounts can be built in small or large quanties and increased or decreased with ease over time.
