Renewable gas is one of the most environmentally sound alternative energy sources.  Wärtsilä Hamworthy’s gas upgrading and liquefaction plants represent the very latest gas technology to meet the increasing demand. Liquefied methane gases enable efficient distribution to end users.

The first ever Wärtsilä Hamworthy supplied biogas liquefaction plant is located in Norway at Nes Romerike, a region of Oslo. The plant produces liquid biomethane to be used as fuel for Ruter AS, Oslo’s public transport authority. Replacing diesel with liquid biomethane (LBG) to fuel 135 buses will reduce fossil emissions by 10,000 tons a year.

50.000 tons of food waste a year results in a LBG production of 4000 tons / year.

Small scale liquefaction plants are one of the most important parts in the LNG/LBG supply chain. Wärtsilä’s solution makes it possible to select from different types of modules to fit a specific need.

The biogas plant delivered to Oslo’s Waste-to-Energy agency EGE uses a mixed refrigerant liquefaction technology, which is specially designed for lower liquefaction capacities. The result is low power consumption and simple unmanned operation.

Wärtsilä’s responsibilities at the plant include feed gas compression, biogas cleaning and liquefaction and liquid biogas storage and export.
