Market of Implementation

  • Indonesia


Our project addresses the unemployment in coastal areas with 50% of the employment being women. The project provides sustainable economic growth and with the cultivation of seaweed, CO2 is absorbed from the ocean (deacidification).


At PT SeatechEnergy Indonesia, we developed platforms for the offshore cultivation of seaweed. Unlike the current farming method which uses shallow waters near the coast, our solution enables the use of more space of the ocean. The concept uses platforms designed for harsh ocean conditions that optimizes the growing conditions of seaweed. The concept of large scale seaweed production provides opportunities for increasing value for farmers (quality improvement, traceability/certification of crops). 

For more information on our solution, do refer to our Slide Deck.

Type of Carbon Reduced/Sequestered

CO2 (Carbon Dioxide)

Amount of Carbon Dioxide Equivalent Avoided/Sequestered

Estimated at 1.430 ton per year (farm size 13.000 ton wet seaweed)

Means of Measurement

There is research conducted about the CO2 sequestered by seaweed. The project Ocean2050 is doing research on the sequestration of CO2. Together with the university in Makassar we will research the CO2 content in Cotonnii.
