An increased focus on global warming and the removal of greenhouse gases will in the coming years lead to legislated CO₂-taxes. Carbon Capture (CC) is a solution for companies to lower their CO₂-taxes by reducing their CO₂-emissions.
CO₂ is available to capture from biogas as a cheap by-product, where the purpose of upgrading is the separation of the CO₂ from the biogas. Other alternative CO₂-sources can per example derive from flue gas at an incineration plant or other combustion. Carbon capture through Ammongas-tailored CO₂-separation is a fairly similar process to Ammongas’ biogas upgrading, with high capture-rates to below 1% CO₂ in the treated flue gas after CO₂ has been separated. This could be further enhanced by incorporating pre- and post-treatment procedures for potential sulfur (SOx) and nitrogen oxides (NOx) present in the gas composition.
With many years of experience within CO₂-separation, Ammongas has acquired a great expertise in CC-plants in biogas. This expertise has since then been transferred to capturing CO₂ from flue gas. In 2021, Ammongas won the National District Heating Award in collaboration with Thisted and SEG A/S for their demonstration of carbon capture from waste-heat flue gas by utilising Ammongas Carbon Capture technology.
As a resource, CO₂ can be utilised in several ways. Depending on the end-use, the CO₂ can through the Ammongas Carbon capture plant be delivered with a quality of +99% CO₂ for storage and up to food-grade or methanol quality.
