ZUG, Switzerland – Allseas has acquired Bluerise, a developer of ocean thermal energy conversion (OTEC) technology that delivers renewable energy solutions. 

Based in Delft, the Netherlands, Bluerise has been researching and developing OTEC technology for nine years. The company designs systems that use the natural temperature difference in the ocean between cold deepwater (5°C/41°F) and warm surface water (25°C/77°F) to generate electricity.

OTEC generates renewable energy by harnessing the heat in ocean surface water to evaporate liquids with a low boiling point (such as ammonia). The vapor drives a turbine that generates electricity. After the vapor transfers its energy, a heat exchanger condenser cools the vapor, turns it back into liquid and a pump conveys it to the heat exchanger evaporator to repeat the cycle. 

Allseas said it will use its offshore expertise and deepwater technologies to advance Bluerise’s concepts and accelerate the implementation of OTEC technology for renewable energy projects.
