1.4. Other Technologies to be developed
Akuo has already Responded to a French Government Call for Tender for a 5.6MW Pilot
Farm.
Akuo is realizing Feasibility Study for Offshore Floating
Wind in French Caribbean with Alstom and DCNS.
Akuo is already working on SWAC projects with its
partner DCNS.
Tidal Current SWAC Floating Offshore Wind
1.5. OTEC: A winning partnership for a world premiere
NAUTILUS : 5.6 MW onshore plant
Partnership between Entrepose,
Geocean, DCNS and AKUO
Commissioning expected in 2017
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
2.1. 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. 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, 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
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)
6.1. 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
