Ultra-energy efficient carbon capture
The next generation of carbon capture technology
The Net Zero clock is ticking
Carbon capture is central to any realistic plan for decarbonising hard-to-abate sectors, according to the Intergovernmental Panel on Climate Change (IPCC). However, the energy intensity and costs of incumbent scrubbing solutions are hindering the rollout in industry. Until now…
We have developed an ultra-energy efficient carbon capture technology that overcomes these deployment barriers.
Our technology, slashes energy demand by up to 80%, cuts cost of capture and provides industrial emitters with an efficient and economical solution to decarbonise.
A step change in innovation
We have combined advanced solid sorbents (Metal-Organic Frameworks or MOFs) with mature vacuum swing technology to enable the efficient separation of CO2 from process emissions via a “heatless” and solvent-free system.
By using pressure rather than heat, we slash the energy penalty and cost associated with carbon capture.

The next-generation technology
What is it?
Our filtration machines are designed for point-source carbon capture. They utilise ground-breaking MOF solid sorbent materials and operate via vacuum swing adsorption (VPSA) – a mature already scaled, gas separation technology.
How does it work?
The CO2-rich flue gas is conditioned and routed to the carbon capture unit where carbon dioxide is selectively captured by the MOF filters. The lean flue gas returns to the stack to be released to the atmosphere. Once the MOF filters are suitably saturated, they are regenerated and using vacuum rather than heat release the CO2 into a high-purity stream ready for downstream operations. During this regeneration, the CO2-rich feed gas is diverted to another parallel column, providing continuous removal.

Unique Features, Game-Changing Benefits
Ultra-Energy-Efficient
Our machines use pressure instead of heat to separate CO2. This decreases the energy penalty for carbon capture by up to 80% compared to traditional solvent solutions.
“Heatless” Capture
Our machines do not require steam to be operated and are powered solely by electricity, enabling easy integration to existing processes. Moreover, the carbon intensity of a plant can be further reduced by leveraging renewable electricity supplies.
Mature Process Technology
Our systems are based on vacuum swing adsorption, a mature and proven separation technology that has been industrially applied at scale for gas generation over many decades. Therefore, the manufacturing capabilities and supply chains already exist for rapid large-scale deployment, minimising the scale-up risk usually involved with the adoption of other 2nd generation capture technologies.
Scalable
Our systems are designed to be modular, providing the flexibility for capturing CO2 at different scales. Their modular nature enables to de-risk investments for carbon capture by gradually adding capacity in alignment with the progression of decarbonisation goals.
No Toxic Solvents
Unlike most carbon capture technologies, we do not use toxic solvents that can evaporate through time and release hazardous emissions. Our filters consist of stable solid sorbents with minimum environmental impact.
Flexible Applications
Our tailormade and simple-to-integrate solutions use very selective MOF sorbents, making them highly effective for capturing CO2 from variable point sources. The modular nature of the technology provides also the flexibility to treat a broad spectrum of off-gases, regardless of their scale or type.
Example Markets
Cement
Nuada’s end-of-pipe and heatless solution can be easily retrofitted to cement kilns and capture unavoidable emissions from the calcination process. Our ultra-high energy efficiency machines enable low-carbon cement production with minimum impact on cement producers’ bottom line.
Waste to Energy
Our modular and compact technology is well suited for application in Waste-to-Energy (WtE) plants. Our “heatless” capture process not only facilitates process integration but also results in ultra-high energy efficiency, enabling WtE producers to retain their maximum energy output while achieving negative emissions.
Steel
Blue Hydrogen
Nuada’s technology can be used for blue hydrogen production, the most mature route to produce hydrogen at the scale urgently required for transitioning to a low-carbon economy. Our flexible solution enables low-energy carbon capture from off-gases of the reforming process.
