Bright Renewables to build Carbon Capture Plant with CO2 Liquefaction for EnergieWerk Ilg in Dornbirn, Austria
CO2 capture
EnergieWerk Ilg GmbH, an energy company and producer of biochar, operates a wood-fired heat and power plant that incorporates CHP (Combined Heat and Power) to generate green electricity and heat. The plant emits 2,500 Nm3 of flue gas per hour, part of which is CO2.
Bright Renewables’ modular built carbon capture system CarboPac-C will capture and liquefy 600kg/hr of this CO2. The process will generate 3.7 kilotons per year of high-purity, food-grade bioCO2, which can be sold to the food and beverage industry, replacing CO₂ from fossil sources. BioCO2 is a valuable end-product that can be used across industries for many applications. The CO2-neutral carbonic acid for the beverage industry actively contributes to climate protection. Another goal is use in building materials where CO2 can be stored permanently and represents a carbon sink (CCS).
The CO₂ capture project makes it possible to separate biogenic CO₂ from the flue gases of the biomass heat and power plant. Bright Renewables uses both amine-based carbon capture technology and Vacuum Swing Adsorption (VSA) technology to separate CO2 from flue gas. Both technologies are applicable for the addition of CO2 liquefaction technology and both technologies have a high yield of gaseous CO2. In this Austrian project, amine-based technology is applied.
Small footprint
The carbon capture system and CO2 liquefier will be installed on the roof of EnergieWerk Ilg’s existing facility, reducing its footprint and the use of (costly) land.
Julia Ilg of EnergieWerk Ilg GmbH, said: “Sustainability is at the core of what we do. This carbon capture and CO2 liquefaction plant will help us to reduce our annual greenhouse gas emissions by an estimated 4,000 tons of fossil CO2. This is a major step towards our goal to operate in an ecologically and economically sustainable manner so that we can protect nature while securing a future worth living for future generations.”
Ivan Derkink, Sales Manager at Bright Renewables, said: “Carbon capture allows district heating and other combustion plants to reduce CO2 emissions, resulting in carbon neutral or carbon negative production. It is an essential add-on for companies aiming to make their combustion processes cleaner and more sustainable. We’re proud to implement this plant for EnergieWerk Ilg, who are pioneers in sustainability.”
CO2 liquefaction: natural refrigerant
Because of Bright’s sustainability ambitions, carbon dioxide is used as a refrigerant during the CO2 liquefaction process, replacing traditional synthetic refrigerants such as Freon or Ammonia. CO2 is a natural refrigerant that is environmentally friendly and safe. This technology enhances the liquefaction efficiency, reducing operational expenses and increasing bioCO2 production capabilities. The use of CO2 optimises energy consumption, making it a more sustainable and cost-effective solution.
