XPrize Carbon Sequestration

Arktide is competing in the Carbon Removal XPRIZE competition to develop system to remove over a gigatonne of carbon dioxide from our atmosphere annually. Arktide will use the OTEC process of upwelling of nutrient rich deep ocean water. This will support ecosystem-based fish farming and enhance natural mechanisms of carbon sequestration. Lastly, this column of cold water being brought up from the deep can be used to produce cheap, abundant, renewable energy.

The Sargasso Sea

While extracting excess CO2 from our atmosphere, Arktide will actively be growing Sargassum and other algae. This seaweed has abundant uses, such as in sushi, and as an additive in many foods. Rich in alginic acid, it is used as a thickener and emulsifier. Sargassum can also be used as a fertilizer for corn, squash, and beans. It can be pressed into paper products, reducing the necessary amount of trees to be harvested each year, and even used as an additive in concrete and bricks, reducing construction costs. At a larger scale, Sargassum may even be potentially used to create biofuels.

Early Construction

After the launch of our upcoming series of prototypes, Arktide will scale up production and begin working on larger designs such as a floating marina. All of our designs will use our special Seasteading Cement which will allow these hulls to be produced cost effectively and survive for centuries in the ocean. We plan to build a large semi-circular structure in the Puerto Rico with commercial and residential space available inside. It could have several potential uses, from being a marina, to a dive shop, to containing restaurants and hotel rooms! More information will come out about this seastead when we begin building in the months to come.
