CO2 Capsol´s goal is to be a global leader in capturing CO2 from cement, biomass, energy-from-waste (EfW), power plants and industrial facilities with the Company´s environmentally friendly, safe and cost competitive Hot Potassium Carbonate (HPC) Carbon Capture Technology - Capsol EoP (End of Pipe)

About us


Carbon capture, utilization and storage (CCUS) is crucial to achieving net zero emissions of greenhouse gases by 2050. CO2 Capsol´s carbon capture technology is an essential part in a successful clean energy transition.

Carbon capture contributes both to directly reducing emissions in critical economic sectors and to remove CO2 from facilities such as Energy-from-Waste (EfW) and biomass power plants - so-called negative CO2 emissions. 

CO2 Capsol has a very competitive technology protected by IP rights. The base case revenue model is to license out patents. We negotiate directly with project owners or participate by collaboration with industrial players.

CO2 Capsol is proud to be part of the solution for a sustainable future.




Our main office is in Madserud Allé 2, 0274 Oslo, Norway.

A simplified overview of the Capsol EoP process

The CO2 rich flue gas is compressed to around 5-8 bar(a) (depending on the CO2 concentration) before it enters the bottom of the absorber, where the pressurised flue gas reacts with the downwards flowing of solvent. The lean flue gas leaves the absorber column at the top.

The CO2 rich solvent leaves the absorber at the bottom, is depressurised, and led to the top of the desorber, where the partial CO2 pressure is low, forcing the solvent to release it high CO2 content to the steam flow.

The pure CO2 leaves the top of the desorber, from where it can be liquified and further processed. The lean solvent is lead back to the top section of the absorber.

The history behind the development of the Capsol EoP (End of Pipe) proprietary rights


The Capsol EoP (End of Pipe) patent is the last of several patents developed over a 15-year period. It is covered by patents globally and valid for 20 years.

From conceptual idea in 2003 to an industrial “plug & play” model took 15 years at a cost of several hundred million NOK.

The main building blocks consist of the absorbent Hot Potassium Carbonate (HPC) and pressurized flue gas.

The first successful tests of the technology was at the Värtan power plant in Stockholm as early as in 2008.

However, the market was not ready, and it would take almost another decade until carbon capture started to get traction as a result of climate change and the search for solutions to combat climate change.

This patented, environmentally friendly, safe, cost competitive and flexible carbon capture technology Capsol EoP (End of Pipe) can capture CO2 from Waste-to-Energy (WtE), cement, biomass, power plants and industrial facilities. It is a flexible, stand-alone, retrofit solution which can run on 100% electricity. Hence, it is not dependent on the parent plant or any costly investments in steam production to run the capture unit.

Our goal is simple “We want to be a major contributor in capturing carbon dioxide from industrial facilities worldwide."
