Nova Scotia, Canada
Active Project
10,400 tonnes projected in 2025Project Overview
Tufts Cove represents a breakthrough in Ocean Alkalinity Enhancement (OAE) technology, demonstrating that we can effectively remove CO₂ from the atmosphere using the ocean’s natural carbon cycle. Our “Tank on a Tarp” approach emphasizes simplicity that drives scale, with a tiny footprint delivering massive impact.
At just 3,200 sq ft., our facility removes 3x the CO₂ of the largest Direct Air Capture plant while using only 8% of the space. The site’s electricity consumption is less than 10 kWh/tCO₂, making it one of the most energy-efficient carbon removal solutions available today.
What makes Tufts Cove special is the enclosed, retentive harbor creates a “living lab” environment with ideal ocean conditions for both operation and measurement.

Simplicity Drives Scale
Our revolutionary approach uses minimal infrastructure to achieve maximum impact. The entire operation fits within just two shipping containers, yet delivers 10k+ tonne scale carbon removal annually.
- Rapidly dissolving CaO & MgO balance scale and measurability
- ~1:1 net CDR to feedstock ratio means low costs and high flexibility
- Aligned with existing regulatory structures
- Replicable to all 4 Tufts Cove onsite outfalls
