Biogas fuels for buses
Wärtsilä has been awarded the order to supply a biogas liquefaction plant that will produce fuel for public transport vehicles, mainly in Norway. The Wärtsilä plant will be installed at the paper mill in Skogn, Norway and will convert the cleaned biogas from fishery waste and residual paper mill slurry into liquid fuel. The liquid will be cooled to minus 160°C and stored in insulated tanks. The system has been designed to liquefy small methane-based gas streams. The technology is based on well proven components.
