Wärtsilä supported Denmark’s fossil-free ambition with two large-scale biogas upgrading solutions

The technology group Wärtsilä has supplied two large-scale biogas upgrading solutions to different locations in Denmark. The order was placed by Nature Energy, the world’s leading biomethane company. By injecting biomethane - the end product of upgraded biogas - to the gas grid, Denmark will be taking an important step towards its stated ambition of becoming a climate neutral and fossil-free nation.

The two plants were installed in the towns of Kvaers and Kong, with each plant upgrading more than 40 million Nm3 of biogas each year. This delivers some 470 GWh of green gas energy, equivalent to providing the fuel for more than 45,000 cars. The plants began injecting biomethane to the Danish gas grid by the end of 2022.

The amine scrubber technology is both robust and reliable, providing very low methane slip and cost-effective operating performance. We have worked often with Wärtsilä and are confident, therefore, that the plants will be completed on time and will operate with the usual efficiency.
