CUTTING EDGE ENERGY TECHNOLOGY
Bluerise has developed cutting edge energy technology to harness the ocean’s power for sustainable electricity and cooling where it’s needed most: in the tropics
In this part of the world more than a billion people live close to the coast and more than half of the expensive and unsustainable electricity is used for air-conditioning.
The ocean covers 70% of the planet. It’s our biggest natural solar collector. The surface collects and stores vast amounts of heat from the sun, but at the same time, the deep ocean is very cold. This temperature difference in the ocean is a giant source of sustainable energy, sort of like a big battery.
EFFICIENT AND SUSTAINABLE The company uses this resource to provide very efficient sustainable cooling for buildings in the tropics by pumping ice-cold water from a 1,000 metre depth. These so called deep seawater district cooling systems are 10 times more efficient than regular air-conditioning and it saves 90% of the
OTEC demonstration plant
energy used for cooling. This translates into cost savings that can go up to 60% or even more. Typical applications are cooling of houses, hotels, data centres, airports, but also greenhouses.
GENERATING ELECTRICITY Moreover, Bluerise generates electricity using the temperature difference between the surface and the deep water in tropical oceans. This energy technology, known as Ocean Thermal Energy Conversion (OTEC), is an important addition to the energy mix, since it’s available year-round, day and night. OTEC provides lower costs of energy compared to oil based generation in small island and isolated grids and attracts new industries and research to diversify and enhance an island’s economy.
Together with their partners, Bluerise is currently developing projects in
Curaçao, Jamaica, Colombia and Sri Lanka. These projects will open up many new opportunities for commercial rollout to the wider market.
WHEN IS THE FIRST SYSTEM OPERATIONAL?
Design, build and testing of the OTEC demonstration system started in 2012 together with Delft University of Technology. The first project in the Caribbean is expected to break ground in 2018.
NEW OPPORTUNITIES Berend Jan Kleute, CTO Bluerise BV concluded: “Together with our partners, Bluerise is currently developing projects in Curaçao, Jamaica, Colombia and Sri Lanka. These projects will open up many new opportunities for commercial rollout to the wider market.”
