Bluerise develops Ocean Thermal Energy solutions. Bluerise was conceived in 2009 by a team of experts that arrived to the conclusion, that, by applying state-of-the-art 21st century technology, Ocean Thermal Energy can become a substantial part of the future sustainable energy mix.

Our mission is to bring the cost of OTEC down to a competitive level and to provide a vast, baseload source of renewable energy to our customers.

Why we do this

Although tropical regions currently account for less than 30% of the current global energy demand, the tropics will become the most significant energy market within the next 20 years.  At current rates of growth over half of the world’s population will live in the tropics by 2050, a population that is increasingly more affluent as the developing world rises from poverty.  At the same time over 40% of the world’s population is located within 100kms of the ocean, making the use of Ocean Thermal Energy not only attractive but also an imperative solution for the future energy mix.

Why we think it’s possible

Cooling represents the most important energy need of tropical coastal areas. By taking advantage of economies of scale in high cooling demand clusters, Seawater District Cooling system becomes an attractive economic alternative to conventional HVAC systems.


Although OTEC systems have been technically proven for decades they had been perceived as ‘too expensive’. Today, advancements by the offshore marine industry in the past 2 decades; control and automation systems enabling remote management; and clever engineering and manufacturing enables us to provide systems that are economically competitive now in islands and isolated areas and that will be competitive with conventional continental power sources in the future without the need for storage. Initially, Seawater District Cooling systems combined with small scale OTEC provide a financially attractive solution while minimizing technical risks.
