Equatic Singapore Pilot

Singapore

Equatic’s seawater electrolysis couples carbon dioxide removal (CDR) from the atmosphere with the generation of green hydrogen at the lowest costs.

Equatic spun out from the UCLA Samueli School of Engineering’s Institute for Carbon Management to deploy the first technology that combines carbon dioxide (CO2) removal and carbon-negative hydrogen generation. Addressing both legacy and future emissions in a single process, the multi-product climate solution enables decarbonization at the scale, speed and cost necessary to mitigate climate change. Equatic will remove 62,000 metric tons of carbon dioxide and will deliver 2,100 metric tons of carbon-negative hydrogen to Boeing.

CarbonBlue

Maagan Michael, Israel

A first-of-its-kind pilot of marine calcium looping direct ocean capture integrated with a desalination facility.

The project is a pilot facility that demonstrates CarbonBlue’s water-based calcium looping technology. It is integrated with a brackish water desalination facility in Maagan Michael, Israel. Operation at full capacity of 400 tpy will commence in 2024.
Country: Israel
Status: In Development

Equatic X Deep Sky

Québec, QC, Canada

Equatic’s seawater electrolysis couples carbon dioxide removal (CDR) from the atmosphere with the generation of green hydrogen at the lowest costs.

Equatic will deliver and install an electrolyzer unit to be operated at Deep Sky’s pilot facility in Quebec in 2024. The unit will have the capacity to remove 365 tons of carbon dioxide per year and will demonstrate the potential for Equatic’s technology ahead of larger-scale deployments (100,000+ tons per year).

Banyu Carbon

CoMotion Labs at Fluke Hall, University of Washington

Uses sunlight to degas seawater

Banyu uses sunlight to capture CO₂ from seawater. A reusable, light-activated molecule that becomes acidic when exposed to light causes carbon dissolved in seawater to degas as CO₂, which is then stored permanently. Because only a small portion of the visible light spectrum is needed to trigger the reaction, this is a highly energy-efficient approach to direct ocean removal.

Captura

Kårstøvegen 1, Sekundær Fylkesvei 798, 5565 Tysværvåg, Norway

Uses established electrochemical concepts to enable gigatonne removals

Developed and proven in Caltech’s laboratories, Captura uses established electrochemical concepts to enable gigatonne-scalable solutions for removing carbon dioxide from the atmosphere via direct ocean capture. We capture carbon dioxide using only renewable electricity and ocean water, producing no by-products. Captura’s mission is globally scalable carbon capture to support a sustainable future for the world’s climate.

SeaO2

Afsluitdijk, Breezanddijk, The Netherlands

Dutch Ocean Carbon Removal company harnessing the potential of the oceans

SeaO2’s solution is Direct Ocean Capture, which relies solely on renewable electricity and seawater as inputs. The process uses electrochemistry to strip out CO2 from seawater, which in turn absorbs it from the atmosphere.
