Why do we need to remove CO2 from the atmosphere?

About Us

Following investment in 2021, the team at NEG8 Carbon have started to commercialise our technology by producing a working prototype 1 tonne CO2/annum carbon capture unit in 2022. We are now in the process of scaling up the technology to our full-scale commercial units.



Initial design phase completed and commercialisation centre established


Demonstration Unit Produced


Production of 1st Modular Full Scale CO2 Capture Unit


1 Megatonne CO2 Captured


10 Megatonne CO2 Captured


100 Megatonne CO2 Captured

Developing carbon capture technologies in Waterford, Ireland

Our Waterford site uniquely provides the ideal environment for developing our groundbreaking carbon capture technology. The location also provides access to sophisticated prototyping and manufacturing capabilities which will help to address the global challenges of climate change and global warming.


Over the next decade, we require capital to achieve atmospheric CO2 capture rates of millions to billions of tonnes.

Funding will unlock the next phase of NEG8 Carbon’s growth and technology scale-up. We are seeking investors with similar ambitions to us.
