What if flue gas could clean itself with its own water?
Aqualung Carbon Capture’s absorbent-free membrane uses the water vapor already in flue gas to separate CO₂. That makes carbon capture practical for emitters that conventional technology can’t serve.
Carbon capture that fits the 85% of emitters conventional technology leaves behind.
Small, dispersed and low-concentration sources such as cement kilns, gas turbines, ships and waste-to-energy plants make up most industrial CO₂. They are also where amine columns are too big, too steam-hungry or too costly. Our modular units are built for them.

How it works
Two membrane stages. No absorbents, no regeneration heat.
01
Water does the work
The water vapor in flue gas, usually treated as an impurity, activates the membrane.
02
Coated hollow fibers
Hollow-fiber membranes are coated with a thin polymer layer that preferentially targets CO2 with the help of water.
03
Bulk separation
The first stage selectively pulls CO₂ from the flue gas while the other gases do not react and are rejected.
04
Purification
A second stage refines purity, delivering a CO₂ stream ready for utilization or storage.
Aqualung Carbon Capture: enabling clean carbon capture for the wider market
Like a filter, at the molecular level.
Aqualung Carbon Capture will accelerate Carbon Capture, Utilization and Sequestration (CCUS) projects by providing solutions for a wide range of industrial emitters and fuel sources across the spectrum, from natural gas to cement production.
Aqualung Carbon Capture uses coated membranes to passively separate different gas molecules, almost like a filter. The video gives an overview of the technology behind our carbon capture membrane.

What if we could remove carbon emissions using water from the flue gas?

Aqualung Carbon Capture membrane technology is a high-performing, absorbent-free process for reducing greenhouse gas emissions from heavy industry.

Profitably unlocking material amounts of carbon capture across every industry.

Our goal is to provide the lowest-cost, lowest-footprint and most environmentally friendly carbon capture solution.
Pilots & projects
Our Projects

Industrial: Cement, Lime, Pulp & Paper, Mining & Metals
Aqualung’s patented membrane technology has been proven at two cement installations, where the unit operated above targeted goals.

ENERGY: Power, LNG, Refining & Petrochemical
Our commercial pilot in Magnolia, Arkansas demonstrated carbon capture at a small emitter. The unit took 100% of the flue gas from a gas fired emission source.

Shipping and Transportation
Aqualung built a R&D test rig on a 250 kW diesel engine. Aqualung worked with Marine Classification Societies towards approvals for onboard installation.

SEQUESTRATION: Onshore/Offshore Sequestration, Pipelines and CO2 Transportation
Aqualung is seeking to provide a full value chain solution for our customers. We have formed strong partnerships with sequestration providers, CO2 pipeline operators and CO2 tankers to cover every mode of CO2 removal.
Target markets
From natural gas to cement production.
We have developed concepts and economics with end-users and specialist partners for the capture equipment and for the logistics, sequestration and utilization behind it.

“SigmaRoc has evaluated various carbon capture technologies to meet our ambitious decarbonization targets. The Aqualung technology is well suited to the lime industry due to the modularity, small footprint and cost. Aqualung has been a great collaboration partner for the Köping kiln pilot and scale-up project. We look forward to continuing to work with them as the technology matures.”
