The Spanish technology company and Green Gas Solution partner ECOTEC has secured a significant contract from the Greater Copenhagen Utility, HOFOR, for upgrading biogas at the Damhusåen Wastewater Treatment Plant. This project marks an important milestone in HOFOR's goal to deliver CO2-neutral gas to their customers.

The project involves the purification and upgrading of biogas supplied to HOFOR from BIOFOS' wastewater treatment plant. Using advanced membrane technology from ECOTEC's sister company, BIMEO Solutions, the biogas will be upgraded to a quality suitable for further processing. This will ensure a stable and sustainable energy source, reducing reliance on fossil fuels.

Òscar Carretero, CEO of ECOTEC, commented on the project: "We are excited to collaborate with HOFOR on this groundbreaking biogas upgrading project. BIMEO's advanced membrane technology will play a crucial role in delivering clean, sustainable town gas to Copenhagen, in line with our commitment to innovation and environmental sustainability."

By utilizing locally produced biogas, HOFOR can offer a renewable energy source that contributes to the green transition, enhances energy security, and reduces CO2 emissions. The project supports HOFOR's goal of delivering CO2-neutral energy solutions.

"This project is an important milestone. We have agreements to receive biogas from all three wastewater treatment plants in the city. Thus, Copenhageners' own wastewater is converted into biogas, which is mixed into the town gas. Our plan is to become self-sufficient and deliver 100% CO2-neutral town gas by 2025, and with the establishment of this membrane upgrading plant, we will achieve that goal,” says Morten Stanley, Head of Gas at HOFOR.

The project is managed by the Danish firm Nordic Green Engineering with ECOTEC as the main contractor. ECOTEC has extensive experience in building and maintaining desulfurization and other gas treatment plants in Denmark, while the Damhusåen project will be the first biogas upgrading plant that BIMEO installs in Northern Europe. Since its founding in 1991, ECOTEC has specialized in environmental technology with a focus on innovation and sustainability. BIMEO Solutions, a sister company to ECOTEC, specializes in advanced membrane solutions for biogas upgrading.

BIMEO's technical solution uses Sepuran® membranes from EVONIK, known for their high efficiency and reliability in separating CO2 from methane. This technology ensures optimal upgrading of biogas to natural gas standards, making it suitable for both the town gas network and the natural gas grid.

The project is facilitated by Green Gas Solutions, the leading supplier of hardware to the renewable energy sector in Denmark, representing ECOTEC and BIMEO commercially in the Nordic region.
