  • Our vision

    We unlock Ocean Thermal Energy Conversion, by a low tech approach on the main technical barrier, the cold water pipe.

    Clean energy 24/7 in 100 tropical countries

    OTEC converts a difference of 20 degrees between the surface and the 1000m depth layer of the oceans into electricity using thermodynamics





    Available cold water pipes are made for oil and gas

    Recent OTEC projects failed because of the technical and economical issues about the CWP. Existing pipe technologies are adapted to the revenues for oil extraction.

    Pumping water is significantly less profitable, thus the pipe design should considerably differ.
