Planting Kelp Forests & Seawead
The south-west coast of Africa is ideal for planting kelp-forests to absorb CO2. We are in contact with local authorities to get the allowance for our project. In Australia, we work on a pilot between Melbourne and Adelaide (2024). Kelp is growing up to one meter per day. You need however a depths of at least 40 meters and temperatures with maximum 18 degrees celsius, which is a litte bit different for every kind of kelp. Kelp can be easily grown in greenhouses and planted on the seabed with a new, specific solution from Ocean Quest Per square kilometer you can plant at least 10’000 kelp trees. For a distance of about 1000 km and let’s estimate a possible topollogy in 200 km, at least 2 Mio kelp trees can be planted. We estimate, that we can plant in 2025 about 500’000 little kelp plants and 1 Mio in 2026. Every kelp plant of 45 meters can absorb about 0.5 – 0.8 tons of CO2, and also toxins, microplastic and more !
We estimate a total coastline of about 2000 miles from Cape Town until Skeleton Coast in Namibia. By studying the topology of the seabed, the temperature and the currencies, around 197 miles can be used for planting kelp, at least. Assuming, that we start with a stripe of just one mile in width, 10’000 or more kelp can be planted per square mile. Overall, this sums up to 1’97 Mio kelp plants. A kelp plant of 45 meters (after few years) can absorb to about 0.6 – 0.8 ton of CO2 per year. And Kelp is growing very fast, up to 0.4 meters a day. Hence, seaweed biomass carbon’s final carbon emission factor is 0.7933 (2/3 + 1/3 × 0.38 = 0.7933). Today, it is estimated, that all kelp can store around 5 Mio tons of CO2. So, there is still plenty of room for improvement …. So, we hope to get the Ok from the authorities soon !
Planting the Biggest Kelp Forests of Mankind
Biological Carbon Capture & Storage (CCS)
Considering 37 Bio tons CO2 produced by mankind per year
We will use the Depths of the Oceans below 2100+ meters for long term
storage of 750 years (University of Stockholm), using containers made out-
of bamboo, compressed by 500 degrees Celsius (Pyrolysis). One Carbon
Certificate (1t) for long-term storage is worth today in the average ca. 30 US
with a bandwidth between 5 US dollars (private trade) and 76 US dollars
(carbon dioxide stock exchanges). Forecasts until 2030 are 200 US dollars …
Bamboo
Beside South-West Africa, we already started in Melbourne, Australia, and
will continue in South America and New Zealand – before conquering the
Ocean plateaus between those three continents and Antarctica
But there are often restrictions like harbors, marinas, natural reserves, etc.
So, there is only endless space for Kelp farms far away from the coasts …..
