It’s no secret that the East River is heavily polluted. Sewage runoff is dumped into the strait approximately 70 times per year, which releases bacteria and makes the East River a body of water New Yorkers probably don’t want to swim in. However, the East River’s carbon-intensive waters are perfect for carbon capture. Vycarb, a startup that accelerates the water’s natural ability to sequester carbon dioxide and measures the carbon cycle, has taken advantage of the strait’s environment. The company was founded in 2022 by climate scientist and chemist Garrett Boudinot, whose earlier research focused on measuring carbon removal. The East River pilot project operates out of the Brooklyn Navy Yard and is Vycarb’s third pilot. The startup has also tested out its method off Governor’s Island and East Hampton, New York, and its mechanics are growing with each iteration: Vycarb’s Governor’s Island equipment is a few feet tall, while its current iteration is a shipping container topped with solar panels that power its operations. The Vycarb method: While the ocean absorbs carbon dioxide, coastal waters such as the East River actually emit carbon, too. That’s because some of the organic matter that enters the water from sewage and other runoff becomes carbon dioxide. Thus, the water ends up having more carbon dioxide in it than the surrounding atmosphere, so it releases carbon into the air to reach an equilibrium. Vycarb “targets” the excess carbon in the water and converts it into HCO3, a stable molecule that won’t degrade in water for 10,000 years at minimum. That transformation happens inside Vycarb’s reactor, a long black tube that sits in the water of the East River and connects to the shipping container. Keep reading here.—TC |
