A flywheel energy storage system works by spinning a large, heavy wheel, called a flywheel at very high speeds. The energy is stored as rotational kinetic energy in the spinning wheel. When electricity is needed, the flywheel's rotational speed is reduced, and the stored kinetic energy is converted back into electrical power using a generator.

Osama El Durrat, Advisor to the Prime Minister for Electricity and Renewable Energy Affairs, pointed to Libya's ongoing efforts to improve energy security.
A study performed by (Aldali and Ahwide, 2013) proposed analysis of installing a 50 MW solar photovoltaic power plant PV-grid connected with a tracking system in Libya. Solar PV modules of 200 W are used in that study due to its high conversion efficiency.
A recent MOU between UAE-based Alpha Dhabi Holding and GECOL aims to construct two additional solar plants in Libya, with a target capacity of 2 GW. Notably, Libya's vision for its renewable energy sector transcends its borders and aims to capitalize on its strategic position as the North African gateway to Europe.
