ECOTEC selected to deliver Q-REN desulphurization technology for two Vireo biogas plants in Norway

ECOTEC is pleased to announce that Vireo AS has selected ECOTEC’s Q-REN regenerative chemical desulphurization technology for the new biogas plants at Hardanger and Lista in Norway.

Both facilities are currently under development and are expected to be commissioned during 2026 and 2027, contributing to the expansion of Norway’s biogas infrastructure and the conversion of organic residues into renewable gas for industry and transport.

For both plants, ECOTEC will deliver its Q-REN regenerative chemical H₂S removal system, a technology selected for its highly efficient hydrogen sulphide removal combined with low CAPEX and low operating costs. The system ensures stable gas quality and reliable operation for downstream upgrading and utilisation of the produced biomethane.

“Vireo conducted a thorough tender process involving several suppliers of scrubber technology. Following a comprehensive evaluation, Ecotec achieved the highest overall score. We placed particular emphasis on quality, operational reliability, and low operating costs—areas in which Ecotec came out as the winner. We now look forward to mobilization and the commissioning of the scrubber technology in our two upcoming projects,” says Richard Kringlebotten, CPO at Vireo AS.

For ECOTEC, the projects represent an important step in supporting the continued development of renewable gas infrastructure in Norway.

"We are proud to have been selected by Vireo for both Hardanger and Lista," says Oscar Carretero, CEO of ECOTEC. "These projects highlight the growing importance of robust gas treatment technologies in modern biogas plants. Our Q-REN regenerative desulphurization technology combines high removal efficiency with low capital and operating costs, while ensuring reliable gas quality for downstream upgrading and utilisation."

Both projects further strengthen ECOTEC’s growing presence in the Nordic biogas market.

Green Gas Solutions, ECOTEC’s representative in the Nordic region, supports the projects commercially and technically throughout development and implementation.
