Vessel Manufacturing Factory

Panama City, Panama

Uses solar unmanned vessels to sink invasive seaweed to the deep sea.

Pull To Refresh’s carbon removal solution is highly scalable due to its deployment in the open ocean, which offers abundant space for expansion. This approach is both inexpensive and energy-efficient, utilizing solar power and the natural process of photosynthesis to minimize costs and environmental impact. The carbon is stored for over 1000 years thanks to the deep-sea environment’s cold temperatures, high pressure, and slow-moving horizontal currents. This ensures long-term sequestration.

Marine Permaculture by Climate Foundation

Philippines

Marine Permaculture

With kelp’s help, marine ‘permaculture’ (farming in a sustainable and self-sufficient way) has the potential to turn not only the ocean round but the whole planet – because once we grow it at scale, kelp gives with one hand (food, feed, fuel, fertiliser and more) and takes with the other (carbon, out of the atmosphere and upper ocean, storing it safely in the middle and deep ocean for thousands of years).

Global Algae

Kauai, Hawaii, USA

A new type of farm

Global Algae’s vision is to harness the unparalleled productivity of algae to provide food and fuel for the world, dramatically improving the environment, economy, and quality of life for all people.

Running Tide

Running Tide

Portland, Maine, USA

On a mission to harness the power of the ocean since 2010.

Running Tide partners with nature to remove carbon durably and at scale. Made with materials from nature, their various Carbon Buoys designs are created to accelerate natural processes in the ocean. This work moves carbon from the fast cycle to the slow cycle, providing a pathway toward climatically relevant scale.

Seaweed Generation

Jolly Harbour, Antigua and Barbuda

Sinks invasive seaweed to the bottom of the ocean, locking up carbon for hundreds of years

Seaweed generation uses robots to sink invasive seaweed into the deep ocean, locking away carbon for hundreds of years. Sinking Sargassum seaweed also helps prevent environmental disasters caused by the seaweed when it hits coasts, where it can also severely impact human health and livelihoods. It has the potential to scale to millions of tonnes of carbon removal.

Seafields

Seafields

Kingstown, Saint Vincent and the Grenadines

Captures and grows seaweed for carbon-negative bio-products.

Seafields capture and grow seaweed for use as bioplastics, fertilizer, and biofuel. Any seaweed not sold to industry is shredded, baled, and sunk to the ocean floor, where the carbon it contains can remain sequestered for hundreds of years. At scale, this could remove around a billion tonnes of carbon dioxide from the atmosphere annually.
