Seawater cooling systems are a technology being using in offshore energy production to improve power generation and reduce emissions. They will reduce up to 90% of CO2 emissions for air conditioning and up to 25% for electricity production for fossil fuel power units. 

 2H is currently applying its extensive experiences in risers and pipelines to design sea water intake solutions that cool down power units generation and significantly reducing CO2 emissions. The technology is based on steel or polymer risers bringing sea water from deep sea to the surface power unit. Water is used to replace the air cooling of the production system. Deep sea water captured is between 5°C to 15°C at water depths of up to 1000m. The performance of the cooling unit increases in ultradeep water.
