Exploring OTEC and Hydrogen Technologies

What is Ocean Thermal Energy Conversion (OTEC)?

• OTEC is a type of underwater farming technique.

• OTEC is a process for capturing carbon emissions from the ocean.

• OTEC is a method for desalinating seawater.

• OTEC is a renewable energy technology that generates electricity using the temperature difference between warm surface ocean water and cold deep ocean water.

How does OTEC contribute to hydrogen production?

• OTEC uses fossil fuels to produce hydrogen.

• OTEC relies on nuclear energy for hydrogen production.

• OTEC generates hydrogen directly from seawater.

• OTEC contributes to hydrogen production by providing renewable energy for electrolysis to split water into hydrogen and oxygen.
