Are flywheel energy storage systems a viable alternative to batteries?
This mismatch between supply and demand necessitates effective energy storage solutions. While batteries have been the traditional method, flywheel energy storage systems (FESS) are emerging as an innovative and potentially superior alternative, particularly in applications like time-shifting solar power.
Could flywheel technology be a key part of our energy storage needs?
Flywheel technology has the potential to be a key part of our Energy Storage needs, writes Prof. Keith Robert Pullen: Electricity power systems are going through a major transition away from centralised fossil and nuclear based generation towards renewables, driven mainly by substantial cost reductions in solar PV and wind.
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
Are flywheel systems a good choice for solar power generation?
Flywheel systems are ideal for this form of energy time-shifting. Here's why: Solar power generation peaks in the middle of the day, but energy demand peaks in the late afternoon and early evening. Flywheels can quickly absorb excess solar energy during the day and rapidly discharge it as demand increases.

What is the African single Electricity Market (afsem)?
On June 3, 2021, The African Union oficially launched the African Single Electricity Market (AfSEM). This marked the commencement of an electricity market that connected the power supply infrastructure of the Union's 55 member countries. The goal is the development of one continuous eficient and afordable electricity market across the continent.
How reliable is Africa's electricity supply?
Electricity supply reliability remains a huge challenge for countries across Africa. Power rationing, outages, and grid collapses are huge fixtures for many markets. According to a 2022 survey by Afrobarometer, only 43% of Africans reported a reliable electricity supply, with significant variation across countries.
What is Africa's energy potential?
Africa has huge renewable energy generation potential. According to the Global Solar Atlas, the continent's average solar energy potential is 4.51 kWh/kWp/day, the highest of any region globally. Also, about 90% of the continent's hydropower potential remains unexploited— the largest proportion of untapped capacity globally.
How will Africa benefit from interconnected power grids?
Expanded electricity trade through a continent-wide interconnected power grid will link African countries' power networks ensuring that countries and regions that produce surplus energy can transmit it to regions with a power supply deficit.
