NAUTILUS (Martinique) – Onshore NEMO (Martinique) – Offshore

NEMO : 16 MW offshore plant

Awarded a 72 M€ European Union funding for the NEMO project

Partnership between DCNS and AKUO.

Commissioning expected in 2018

2. History of OTEC

2.1. OTEC, an invention part of French industrial heritage

" ... In fact, I could have established a current between wires immersed at different

depths, obtaining electricity through the difference of temperatures... “

Captain NEMO In Twenty Thousand Leagues Under the Sea

(1870), JULES VERNES.

From Jules Verne’s intuition… … To a scientific formulation

First expression of OTEC concept

Jacques Arsène d’Arsonval first expressed the OTEC scientific principle in 1881,

In the 1920’s , Georges Claude was the first to envision the industrial interest of OTEC

and realized the first technical tests.

“One day, the sea will be the first energy supplier of humankind"

2.2. OTEC, a technology born in the Tropical Atlantic zone

First OTEC plant in CUBA

First onshore prototype in Cuba (1930) First offshore prototype in Rio (1934)

The cold water pipe, towed on the Rio Canimar, Brasil

Cold Water Pipe in Cuba (1,6m wide, 2km long)

Plan of the First Offshore OTEC plant

Heat exchanger of the offshore plant « Tunisie »

« Tunisie », first offshore platform off the coast of Rio

(22MW production during 11 days)

2.3. OTEC, an adventure bonded to overseas territories

Sea Water Air Conditionning already in operation for

Hotels in Bora Bora (2007) and in Tetiaroa (2014), French

Polynesia.

Offshore and Nearshore realized by our premium

partner GEOCEAN

In the 1980’s, IFREMER

(French Research institute for exploitation of the sea) started

to design a 5MW onshore prototype in Tahiti.

DCNS’ Onshore prototype in operation since 2011 in

Reunion Island.

5MW Onshore Project (IFREMER) Tahiti, French Polynesia

SWAC Bora Bora & Tetiaroa

Onshore Prototype, Reunion Island

3. OTEC Technology

3. Technical Facts NEMO – New Energy for Martinique and Overseas

4 units incorporated into a platform based on a simple

closed Rankine cycle

Cold water and hot water pumping.

Warm water discharge

Rankine cycle containing ammonia as the working fluid

A synchronous turbo generator set per each OTEC

unit

Main Equipment Heat Engine

Mooring adapted to the seabed (sediments and

volcanic rocks )

Electrical connection from the platform to the shore via an

undersea dynamic cable

4. NEMO Roadmap in Martinique Island

4. NEMO, the First Offshore Project

Localisation Main Costs

• Technical system validation, • Efficiency optimization,

• Administrative Authorizations,

• Construction

• Operation

• Located in Martinique Island, French Overseas territory.

• Project presented by French Government for the European funding NER300 and awarded of a 72 M€ subsidy.

• Aiming to produce energy at a

lower cost than the average electricity cost on islands.

• Total CAPEX: 296M€

• NER 300 subsidy : 72M€

• Feed in Tariff : 450€/MWh

• 20 years PPA contract • Financing scheme : 20% Equity,

80% Debt.

2013-2018 Project’s roadmap

5. Benefits of OTEC for tropical islands energy issues

Limited visual impact : Installation mostly buried

(onshore), or very slightly visible from the coast (offshore)

Limited land use (compared to wind or PV) , a very sensitive subject on islands

Very limited impact on the environment No noise, no greenhouse gases emission

No significant technological risk Unlimited resource , always accessible

No intermittent and total availability ( nonfatal energy)

Easy to deploy, even in the smaller islands

Producing a secure resource base energy that supports the network

5. Benefits of OTEC for tropical islands energy issues

Acceptability Easy Grid Connexion

Operation costs limited Greenhouse gases free

Significant CAPEX but : - Very Low OPEX

- Easy dismantling - Very Low risk exposure ( resource supply , productible)

6. Market Potential for OTEC

6.1. OTEC, a huge commercial potential

More than 100 countries eligible for OTEC

Estimated market of €25 Billion untill 2030

Floating plants of 25-30 MW

Objective of a production Cost of OTEC Energy < Cost of fossil

energy

Estimated market of €8 Billion

untill 2030

Hybrid Solutions: Electricity + Air Conditioning, drinking water,

aquaculture...

Offshore OTEC : a power production for densely populated area

Onshore OTEC : small production unit for remote islands

6.2. OTEC, Commercial phase has already started

More than 100 countries eligible for OTEC

Feasibility study in Aruba, Virgin Islands, Barbade,

Mexico..

Ideal market for both Onshore and Offshore projects

More than 100 countries have the marine thermal potential to

develop OTEC.

72 preferential areas ( potential Thermal and optimal distance

from from the coast )

AKUO Energy and Pertamina are ready to sign a MOU for 200MW of OTEC Onshore and Offshore Plants

in Indonesia by 2030.

Numerous commercial perspectives in the caribbean Industrial expectations in Indonesia
