Bluerise nears crowdfunding target for first two OTEC projects on Curacao and Jamaica
Within one day after Dutch-based company Bluerise started its crowdfunding campaign for its first project on thermal ocean energy on the Caribbean island of Curacao, it already reached the targeted 250.000 US dollar. After this success, the company has set itself a new goal of 500.000 dollar to be able to realise a second project on the Caribbean island of Jamaica.
At this moment the crowdfunding website states a result of 377.000 dollar and the campaign is still running. Bluerise started the successful crowdfunding campaign on 7 September (on top photo).Bluerise's B-TEC uses the 25 - 30 degrees lower tempersture at 1,000 m depth to generate electricity and to extract cold ocean water for cooling.
Bluerise has developed a new Ocean Thermal Energy Conversion (OTEC) technology to generate energy from the ocean in the tropics.
OTEC-technology uses the temperature difference between the surface and deep layers to generate electricity. The energy production with OTEC is very constant, as the temperatures in the ocean hardly vary between day and night or even between the seasons.
This makes OTEC a very reliable source of energy that can be easily integrated into the electricity grid.On 26 October the campaign website showed 377,940 dollar was raised.
Commercial roll out
The combination of a more efficient thermodynamic system with smart control systems form part of Bluerise’s B-TEC technology which can provide savings of up to 20 percent in costs per kwh.
In the tropics the surface water is 25 to 30 degrees, while the temperature is at 1,000 meters depth between 4 and 6 degrees. Bluerise uses this energy to produce sustainable cooling and electricity.
The company tested a demonstration size advanced OTEC power plant in which mixed working fluids are used and B-TEC is ready for commercial rollout.
In Curacao, Bluerise is working on a B-TEC project at the airport and in Jamaica it is intended to build a cooling plant for the local energy supply company New Leaf Power at the Montego Bay.
Robert Wright, CEO of New Leaf Power, partner Bluerise in Jamaica: ‘Bluerise offers a clean and cheaper alternative by cold sea water 1,000 meters deep to pump up to cool our hotels. This cooling mode is 10 times more efficient, saving up to 90 percent of the energy.’
‘Ultimately, what our customers want, they want cheaper energy, cheaper cooling, that's clean and green’, said Wright.Development of B-TEC at Delft University of Technology.
Energy saving on air conditioning
In the tropics, more than a billion people live near the coast. More than half of the energy goes to air conditioning. These air conditioners use a lot of expensive, non-sustainable electricity and provide a lot of CO2 emissions.
Cold water from the deep ocean is able to cool buildings at a much lower cost in a sustainable way. With the temperature difference between hot water on the surface and the cold deep water, electricity can also be generated day and night.
Because unlike solar and wind energy, ocean energy is always available and does not need to be supplemented by polluting energy at times when the sun is not shining or the wind is not blowing.
