Combating climate change with robots and seaweed
Seaweed Generation is a robotics company that develops technology to harness the power of seaweed for long-term carbon dioxide removal (CDR) and large-scale industrial use cases. For CDR, the company takes an invasive type of seaweed called Sargassum that is building up on a massive scale as a result of climate change. Seaweed Generation's first proprietary robot ‘AlgaRay’ captures and deposits Sargassum into the deep oceans, piloting in 2023.
In 2024, Seaweed Generation will move to a fully commercial operation sinking 5K tons of CO2 (roughly 50K tons of Sargassum) into the deep oceans. The company is making an early start on seaweed cultivation, with its second robot, the AlgaVator, designed to remotely monitor and autonomously manage offshore cultivation.
Notable Achievements
- Raised over $1.3 million pre seed equity round and $900k in grant funding to date
- International patent pending on 4 inventions
- The world's first license to sink seaweed for CDR
Currently Operating in Three Regions
