Developing technology to remove carbon dioxide from the atmosphere MoreLess

Planetary Tech is a pioneering startup that operates in the environmental technology sector, specifically focusing on climate change mitigation. The company's primary mission is to combat climate change by enhancing the ocean's ability to remove carbon dioxide (CO2) from the atmosphere, a process known as Ocean Alkalinity Enhancement (OAE).

OAE is a nature-inspired process that involves adding an antacid to seawater, neutralizing CO2 and reducing harmful ocean acidity. This process mimics the natural geologic capture of carbon but works much faster, acting in months rather than millennia. The result is the safe, permanent removal of CO2, which helps to combat ocean acidification and climate change by restoring the ocean's vital chemistry.

Planetary Tech's business model revolves around the development and implementation of its OAE method. The company uses naturally abundant materials that have been used in water treatment applications for decades. These materials are added to existing water systems, and the treated water is then released into the ocean.

The company's revenue is likely generated through partnerships with scientific institutions, regulators, and local communities interested in implementing their carbon removal methods. They also partner with suppliers of safe antacids produced with a low carbon footprint, which are used extensively in wastewater and aquaculture.

In summary, Planetary Tech is a climate change mitigation startup that uses innovative technology to enhance the ocean's ability to remove CO2 from the atmosphere, thereby combating ocean acidification and climate change.
