Germany-based Schmack Carbotech has been awarded the contract to design and build the plant, which will be located in Sofielund Huddinge (just south of the Swedish capital), with a processing capacity of 2,000 nm³/h of raw biogas. The renewable fuel produced will have a methane content of more than 97% after purification and will be used to supply vehicles powered by natural gas.
The facility, utilizing the region’s organic waste and fryer grease as raw material, will feature Schmack Carbotech’s Pressure Swing Adsorption (PSA) principle, which is characterized by low energy consumption, efficient heat extraction, as well as a high methane yield. It will be also equipped with a CNG station.
Upon completion and commissioning (expected by the first quarter of 2015), the plant will produce about 100 million kilowatt hours of biogas annually, enough to supply about 5,000 vehicles a year with an average mileage of 20,000 kilometers, and will increase the share of Stockholm city’s biomethane by 50%.
“This important new contract at Sofielund brings to bear all of our experience in the development, engineering and manufacturing of turnkey gas upgrading plants,” said Schmack Carbotech International Business Manager, Eberhart Wusterhaus Gomez. “We are very keen to play our part in delivering a low energy yet high yield technology that in this case fits in perfectly with the Swedish government’s long-term thinking to become the world’s first completely oil-free economy”.
