* Background:What is Tidal Energy?

!

Tides are caused by the gravitationaleffect of the Moon, and to a lesser

extent, the Sun, on the world's oceans.

! Tidal power is a form of hydro power

that exploits the tidal movements of

the ocean.

Tides or

Tidal Range (Barrage)

300+ TWh/yr

Tidal / Marine Current

800+ TWh/yr

Global Tidal Energy Resource (IEA-OES)

* Rationale & Motivation

! Untapped Energy from Tidal Currents

!

Tidal In-Stream Energy: Clean & Renewable! High predictability (hourly, ~18.6 yrs)

! Available Extraction Devices (TRL 6-8)

! Island Electrification

! High Cost of Grid Infra: Remote (eg cabling US$1M/km)

!

High Cost of Electricity: Diesel Generators

! Technology tweaking for SEA conditions

! Low Flow (Turbine)

! Biofouling (Materials)

!

Less Harsh Site Conditions (Deployment)! Distributed Solutions (Power System)

! Market: Equatorial Band (SEA++) & more

Potential TISE Sites/Locations

15MWp

(~40GWh/yr)

170MWp

(~450GWh/yr)
