Banyu Carbon aims to radically reduce the cost of carbon capture, hasten the transition to a net zero carbon economy, and slow the effects of global warming. To meet this challenge, Banyu Carbon is developing a process to extract CO2 from seawater using light-activated chemicals that is projected to require a fraction of the energy inputs compared to competing carbon capture methods. We are transitioning from prototypes in the lab towards a larger scale pilot and first-of-kind commercial facility. We have secured a carbon removal pre-purchase contract with Frontier, closed an oversubscribed financing round, and are supported by a stellar team of investors.
