Allseas in renewables push. Buys OTEC firm Bluerise

Offshore oil and gas installation, construction, and decommissioning specialist Allseas has ventured into renewables through the acquisition of Bluerise, a specialist developer of Ocean Thermal Energy Conversion (OTEC) technology.

Based in Delft, the Netherlands, Bluerise has been researching and developing OTEC technology for 9 years, designing systems that utilize the natural temperature difference in the ocean between cold deep water (5°C) and warm surface water (25°C) to generate clean electricity.

Announcing the acquisition of Bluerise on Monday, Allseas said it would use its offshore expertise and record of deep-water technologies to advance Bluerise concepts and accelerate the implementation of OTEC technology for renewable energy projects.

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 is fostering the use of renewable energy sources. OTEC, with its vast offshore energy potential and scalability, matches well with the company’s capabilities. Allseas looks forward to continuing the work performed by Bluerise, founded by Berend Jan Kleute and Remi Blokker, and making OTEC a success,” Allseas said.

For Allseas, a specialist in the offshore oil and gas industry for over three decades, the Bluerise deal is a second important agreement outside of the oil and gas industry in the past month.

Allseas and DeepGreen on June 10 announced they had entered into a partnership with DeepGreen to harvest deep sea battery grade metals “to meet skyrocketing growth in electric vehicle demand.”
