Mission Statement

4

Our goal is to generate competitive and

sustainable base-load power through

Ocean Thermal Energy Conversion (OTEC)and attractive energy efficient

alternatives to air conditioning through

Seawater District Cooling (SDC),

as well as affordable potable water,

sustainable food production, and economic

development opportunities to our customers


Committed to a Sustainable Future

5

We focus our efforts to produce technologies

to meet the world’s four greatest challenges

Increasing Water and Food Scarcity

Growth of Developing Nations with Massive

Infrastructure and Economic Development Needs

Rising and More Volatile Energy Costs

Escalating Pollution and CO2 Levels


• Ocean Thermal Energy Corporation (OTE) is a private

renewable power generation company that is managed by

an experienced and successful Executive Management

Team and supported by skilled Ocean Engineering and Energy Production Teams with over 40 years of experience

Who We Are

6


• In 2010, the current Investment/Management Team

acquired a Hawaii-based ocean engineering company with

over 25 years of experience with OTEC and SDC

• OTE plans to build, own and operate renewable energy systems based upon the principles of OTEC and/or SDC

Who We Are

7


• Several projects are underway:

• 12,000 ton SDC plant and two OTEC plants in The Bahamas

• Agreements in place for multiple OTEC and SDC plants in the

Cayman Islands, US Virgin Islands, the Pacific Rim, Southeast

Asia, and East Africa

OTEC

SDC

Ocean Thermal Energy Conversion is a

process that generates power using the

temperature difference in ocean water

Seawater District Cooling is a process that

uses deep ocean water for air conditioning

What Are OTEC and SDC?


OTEC

SDC

Both OTEC and SDC can also be used to

produce potable water and to develop

additional industries like aquaculture and

mariculture

Thermal Cycle - Rankine Cycle

The Rankine cycle was invented in the 1850s. It is a cycle that converts heatinto work. The heat is supplied externally to a closed loop, which usually useswater. This cycle generates about 90% of all electric power used throughoutthe world, including virtually all solar thermal, biomass, coal, and nuclear

power plants.

A Simple Process


How It Works

All of the working components of a land-based OTEC Plant are above the sea. Only the deepcold water pipe is submerged.

Onshore OTEC Plant

Using the temperature difference of seawater found in tropical climates, land-based OTEC plants produce fossil-fuel free electricity, potable water and opportunities for sustainable food production


Seawater District Cooling

SDC systems can save up to 90% in electricity costs when compared to traditional airconditioning systems. SDC systems range in size from 400 to 80,000 tons of cooling capacityand use millions of gallons of seawater. Once the seawater has been used for air conditioningit can be desalinated for potable water


Why Now?

15

• Four basic reasons OTEC is ready for the world:

• A clean energy source. OTEC delivers an environmentally friendly solution thatproduces electricity without the expense and price-volatility of fossil fuels

• Improved technology. The qualitative analysis of the technical readiness of OTECby experts at the US National Oceanic and Atmospheric Administration (NOAA)suggest that a < 10 MWe floating, closed-cycle OTEC facility is technically feasibleusing current design, manufacturing, deployment techniques and materials

• Need for potable water. Large OTEC power plants can be designed to co-produce 120 million liters of fresh water per day. The OTEC power cycle movesabout four cubic km of high-nutrient deep water per year (1 square km 11.5meters deep each day, enough to grow 70 tons of shellfish meat per day)

• Increased awareness of the effects of climate change. OTEC is carbon-neutraland does not contribute to climate change by burning fossil fuels such as coal,gas and oil

“We are like tenant farmers chopping down the fence around our house for fuel when weshould be using Nature's inexhaustible sources of energy — sun, wind and tide…I'd put mymoney on the sun and solar energy. What a source of power! I hope we don't have to waituntil oil and coal run out before we tackle that.”

Thomas Edison (1847-1931) – American Inventor and Businessman


The Many Benefits of OTEC

16

“The potential of OTEC is great. The oceans are the biggest solar collector on Earth, and there’senough energy in them to supply a thousand times the world’s needs. If you want to dependon nature, the oceans are the only energy source big enough to tap.”

Dr. Joseph Huang – Senior Scientist, NOAA and DOE, USA

• World leadership role in eco-awareness




Competitive Landscape – Oil

Source: EIA Annual Energy Outlook 2012 – Early Release Overview

The rapid rise in crude oil prices in the last three years (118%...from $49.06/barrel in March 2009 to $107.06/barrel as of March 2012) has been reflected in even greater increases in fuel and electricity prices. Everyone is negatively affected by constantly rising oil prices

The Global Water Crisis

21

• By 2025…

• Freshwater demand will rise by 2/3

• 1.8 billion people will be living in countries or regions with absolute

water scarcity, and 2/3 of the

world population could be under stress conditions

• Water withdrawals are predicted

to increase by 50% in developing

countries, and 18% in developed

countries
