Wärtsilä formed Wärtsilä Biogas Solutions, as Wärtsilä Puregas Solutions has merged with Wärtsilä’s biogas liquefaction team. The latter is a unit focusing on liquefying upgraded biogas for end-customer use.
As Wärtsilä said, the market for advanced biofuels is growing. In fact, the European Union, under its RED II directive, has directed that by 2030, member states must mandate fuel suppliers to supply a minimum of 14% of fuel consumption in road and rail transportation from renewable sources.

In addition, in both Europe and the USA, efforts are being made to decarbonise the natural gas grid. Wärtsilä’s biogas technology aspires to support this trend by removing carbon from the waste cycle. Moreover, fossil driven natural gas grids may see a growth towards transporting bio-related gases, like biomethane or even synthetic methane, in the near future.
Wärtsilä’s biogas upgrading plants use its in-house Puregas CA technology, a process that recovers more than 99.9% of the biomethane present in raw biogas. The process separates the CO2 from the biogas via chemical adsorption.
What is more, Wärtsilä has also provided the turnkey installation for the world’s largest bioLNG facility located in Skogn, Norway and will, by the end of 2019, deliver two more bio-LNG plants to customers in Scandinavia. Furthermore, interest from both the European and North American markets is high.
