What is the Master’s in Ocean Thermal Energy Conversion (OTEC)?
The Master's in Ocean Thermal Energy Conversion (OTEC)
Prepares you to assess, design and manage ocean thermal energy conversion (OTEC) projects, a technology that harnesses the temperature difference between surface and deep water in tropical seas. You will study the thermal resource, open, closed and hybrid thermodynamic cycles, heat exchangers, the cold water pipe, platforms and moorings, co-products such as desalination and seawater air conditioning, and the technical, environmental and economic viability of a technology that is still at demonstration stage.
Key advantages
- Emerging technology: A dispatchable renewable source of great interest to tropical islands.
- Complete engineering: Thermodynamics, heat transfer, offshore structures and grid connection.
- Multiple uses: Electricity, desalinated water, cooling and aquaculture.
- A realistic view: Technical challenges, costs and lessons from pilot plants.
- Your own project: A feasibility study for an OTEC plant at a real site.
Programme highlights
- Assess the resource: Analyse the ocean thermal gradient with real data.
- Design the cycle: Model open, closed and hybrid cycles.
- Size components: Calculate heat exchangers and the cold water pipe.
- Integrate uses: Combine power with water, cooling and aquaculture.
- Boost your career: Open doors to engineering firms, marine renewables developers and technology centres.
- Train to harness the ocean’s heat as a clean, continuous source of energy.
