Carboniferous

Orca Basin

Sinks leftover surgar cane and corn fibre into the deep ocean. 

Carboniferous is safely and purposefully replicating the process of anoxic biomass carbon sequestration. We are a BiCRS pathway, storing terrestrial biomass in naturally forming permanent anoxic basins under the ocean.

Vycarb

Vycarb

Brooklyn Navy Yard, Brooklyn, NY, USA

Enabling decentralized carbon removal through real-time, autonomous, and direct measurement of CO2 in water.

With multiple pilots deployed on the US east coast, Vycarb’s modular, autonomous system uses a real-time measurement technology and accelerated alkalinity dissolution to optimize CO2 removal to water’s naturally-changing chemical conditions. Designed for deployment across any high-CO2 waters, Vycarb’s system creates the first fully-measured, ecologically beneficial carbon removal and storage that can be distributed around the world.

BHP X Arca Nickel Mine

BHP X Arca Nickel Mine

Mount Keith, Wiluna WA, Australia

Transform CO2 into rocks

Arca Climate Technologies and BHP have joined forces to launch a new pilot project at BHP’s Mt Keith Nickel West mine in Australia. The project, which is set to run for 18 months, will be focused on testing Arca’s innovative approach to carbon capture and storage using mine tailings. The goal of the project is to demonstrate that Arca’s methodology can effectively capture and permanently store atmospheric carbon dioxide, while also ensuring the integration of the technology is safe within an operating mine.

Arbor Demonstration Facility

Arbor Demonstration Facility

Placer County, CA, USA

Converts wate into clean energy and fresh water

Arbor combines natural carbon drawdown with the permanence and scalability of engineered solutions using an approach called Biomass Carbon Removal and Storage (or BiCRS). Located in Placer County, Arbor’s demonstration facility is modular and is estimated to remove 50k/tons of CO2/year.

Ebb Carbon

Sequim Bay State Park, U.S. 101, Sequim, WA, USA

Enhances ocean’s natural ability to store CO2

Ebb Carbon is pioneering a new carbon removal solution by enhancing the ocean’s natural ability to safely store CO2. Our electrochemical ocean alkalinity enhancement method has the potential to be one of the largest scale and lowest cost approaches to removing excess CO2, while reducing ocean acidity. This first of a kind demonstration project is designed to remove 100 metric tons of CO2 per year at full capacity.
