Product description

PRONOE’s “Ocean Enhancement via Coastal Outfalls” is an innovative green business solution designed to tackle the pressing issue of ocean acidification and enhance CO2 absorption in coastal environments. The system is specifically engineered to treat industrial return flows before they are discharged back into the ocean, effectively reducing acidity levels and raising alkalinity to help neutralize ocean acidification locally.

By utilizing electricity, the system processes discharge streams downstream of existing coastal industrial sites, seamlessly integrating with current infrastructure and regulatory frameworks. This process not only helps in neutralizing ocean acidification but also accelerates the natural uptake of atmospheric CO2 by the ocean, thereby restoring surface water capacity to absorb carbon effectively.

The system also generates high-quality CO2 removal certificates that companies can utilize to showcase verified climate impact. Additionally, it benefits coastal communities by improving water quality and supporting marine ecosystems, making it a win-win solution for both businesses and the environment.

Asset-light and scalable, this solution leverages existing effluent streams, minimizing disruption and maximizing environmental benefits. The foundational vision of this solution is climate-smart and ecosystem regenerative, making it a valuable tool for industrial climate action for businesses, governments, NGOs, and investors.
