Two-stage OTEC Power Cycle

The world’s oceans are the largest natural collector and reservoir of solar energy stored as temperature gradient between the surface warm water and deep-ocean cold water. The potential of ocean energy is limitless for production

of base-load power and commodity of ammonia and fresh water. However, the engineering challenge is to harness the energy with low temperature driving force. E3Tec contends that there is a Window of Opportunity to commercialize OTEC by 2020.

E3Tec’s Visionary Goals of Commercialization of OTEC Plants

Ocean Thermal Energy Conversion

Ocean Thermal Energy Conversion

1. Displacement of petroleum-liquid fuels for power generation in the Island States

2. Production of desalinated water for regions of critical water scarcity

3. Displacement of carbon-based production of ammonia fertilizer

4. Ammonia as hydrogen carrier for economic processing of heavy crude oils and upgrading oil sands

5. Ammonia fuel-cell based distributed power generation
