Growing seaweeds in the tropical seas of the world makes sense because of the presence of almost uniform day and night cycles throughout the year. This makes year-round agriculture on the sea possible.

This fact is especially important since seaweeds have a very high moisture content and are essentially an unstable feedstock unless they are dried. However, the huge volumes of low-cost feedstock required for potential industrial use makes the drying & storage of wet seaweed at a large scale an economically unviable proposition.  Hence the availability of a year-round supply of fresh wet feedstock obviates the need for additional drying and storage and allows tropical seaweed to be considered as a viable industrial feedstock for various applications.

At Sea6 Energy, we have innovated novel cultivation systems to enable the large scale cultivation of vegetatively propagated tropical seaweed at low cost. Furthermore we have demonstrated that it is possible to convert fresh wet feedstock directly into various industrial applications like for Bio-stimulants, Biomaterials (including biodegradable plastics) as well as to crude oil and natural gas.

Using these technologies, it is possible to envisage that we could build an entirely sustainable bioeconomy based on the cultivation of seaweed at large scale in the open oceans before the end of the decade.
