Mission Statement

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
We focus our efforts to produce technologies
to meet the world’s four greatest challenges

Growth of Developing Increasing Water and
Nations with Massive Food Scarcity
Infrastructure and Economic
Development Needs

Rising and More Volatile Escalating Pollution and
Energy Costs CO2 Levels


Who We Are

• 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

• 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

• 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


What Are OTEC and SDC?

Ocean Thermal Energy Conversion is a
OTEC process that generates power using the
temperature difference in ocean water

Seawater District Cooling is a process that
SDC uses deep ocean water for air conditioning


What Are OTEC and SDC?

OTEC
Both OTEC and SDC can also be used to
produce potable water and to develop
additional industries like aquaculture and
mariculture

SDC


A Simple Process

Heat Turbine &
Pipes + Exchangers + Generator

Thermal Cycle - Rankine Cycle

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


How It Works
All of the working components of a land-based OTEC Plant are above the sea. Only the deep
cold 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 air
conditioning systems. SDC systems range in size from 400 to 80,000 tons of cooling capacity
and use millions of gallons of seawater. Once the seawater has been used for air conditioning
it can be desalinated for potable water


Why Now?
“We are like tenant farmers chopping down the fence around our house for fuel when we
should be using Nature's inexhaustible sources of energy — sun, wind and tide…I'd put my
money on the sun and solar energy. What a source of power! I hope we don't have to wait
until oil and coal run out before we tackle that.”
Thomas Edison (1847-1931) – American Inventor and Businessman

• Four basic reasons OTEC is ready for the world:
• A clean energy source. OTEC delivers an environmentally friendly solution that
produces electricity without the expense and price-volatility of fossil fuels
• Improved technology. The qualitative analysis of the technical readiness of OTEC
by experts at the US National Oceanic and Atmospheric Administration (NOAA)
suggest that a < 10 MWe floating, closed-cycle OTEC facility is technically feasible
using 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 moves
about four cubic km of high-nutrient deep water per year (1 square km 11.5
meters deep each day, enough to grow 70 tons of shellfish meat per day)
• Increased awareness of the effects of climate change. OTEC is carbon-neutral
and does not contribute to climate change by burning fossil fuels such as coal,
gas and oil


The Many Benefits of OTEC
“The potential of OTEC is great. The oceans are the biggest solar collector on Earth, and there’s
enough energy in them to supply a thousand times the world’s needs. If you want to depend
on nature, the oceans are the only energy source big enough to tap.”
Dr. Joseph Huang – Senior Scientist, NOAA and DOE, USA

Economic Benefits
• Base-load Power: Available 24/7
• Reduced fuel imports
• Stable utilities pricing
• Reduced capital expense to Power Companies
and Governments
• Affordable incremental power capacity increase
• Reduced burden on existing utilities
• Life cycle cost savings



Environmental Benefits
• Inexhaustible renewable energy from local resources
• Fossil fuel avoidance
• Save ~15,000 bbls oil a year per MW
• Zero emissions
• Save nearly 7,000 tons CO2 a year per MW
• Sustainable fresh water supply
• Energy conservation



Social Benefits
• Affordable fresh water and power
• New industries/jobs/export opportunities (aquaculture)
• Increased fuel flexibility and energy security
• World leadership role in eco-awareness


Competitive Landscape – Oil
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

• 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

We Are Focused on a Solution
Each day, more than 4000 children under the age of five years of age will die because of
unclean drinking water and a lack of sanitation. This situation is expected to worsen.
