OTEC.pptx (Size: 1.88 MB / Downloads: 61)
INTRODUCTION
The first idea about OTEC was given by J.D. Arsonval in 1970.
Heat stored in ocean is converted into electricity.
By products of OTEC like:
fresh water
chilled water and
nutrient-rich water.
Rankine cycle.
OTHER RELATED TECHNOLOGIES
1. Air conditioning.
2. chilled soil agriculture.
3. Aquaculture.
4. Desalination.
5. Mineral Extraction.
APPLICATIONS
1. Electricity generation.
2. Desalination of water.
3. Deep water Mariculture.
4. Refrigeration and Air-conditioning.
5. Mineral Extraction.
GROWTH POTENTIAL
Electricity Capacity Expansion
Additional OTEC systems could be installed
Current system could be upgraded to include more power modules
Clean Water System
Use the power created to create clean water
Install an “Open-Cycle” system to create both at once
Alternative Technology Solutions
Geo-OTEC to power Oil Platforms
Renewable Fuels – Ammonia as a Carbon Carrier
Agriculture – Ammonia as a fertilizer
ADVANTAGES
Renewable source of energy.
Pollution free.
Produce fresh water as well as electricity.
Saves fossil fuels.
DISADVANTAGES
Higher Cost .
20 deg. Temperature is must to establish OTEC plant.
Small scale electricity production.
Construction of OTEC plant is difficult .
SUMMARY AND CONCLUSIONS
Consider methods to reduce system cost, consider:
Sell directly to city to remove “middle-man”
Platform cost savings: less-robust design, shorter CWP
Recommend Africa installation after OTEC is ‘proven’ at large scale
Alternative technology approaches increase possible installation area to include colder water regions
Way Forward Recommendations
Meet early and often with environmental policy teams regarding licensing and permits to ensure compliance and a clear path ahead
Begin talks with Nigerian government to express interest in developing OTEC near Lagos; Establish a partnership with power distributor
Verify ocean temperatures & geography; Consider university research
