Inertial storage is much more complex than just retaining the energy until it is needed, i.e. ''fly wheel'' storage. For tidal inertial storage, the longer the delay in extracting the energy, the greater the total energy that can be extracted, though the maximum delay is limited by bottom frictional losses and the reversal of the tidal forcing.
3 FAQs about [Tuvalu tidal energy storage]
Where does Tuvalu electricity come from?
Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of Funafuti operates the large power station (2000 kW).
How many inhabited islands are in Tuvalu?
It is somewhat complicated because Tuvalu consists of nine inhabited islands. The Tuvalu National Energy Policy (TNEP) was formulated in 2009, and the Energy Strategic Action Plan defines and directs current and future energy developments so that Tuvalu can achieve the ambitious target of 100% renewable energy for power generation by 2020.
What does ADB funding mean for Tuvalu?
The ADB project funding announced in November 2019 will increase production of electricity from renewable energy sources from 15% to 32% in Funafuti and from around 70% to over 90% in Tuvalu's outer islands.
