group Wärtsilä will supply two large-scale biogas upgrading plants to different
locations in Denmark.
Denmark’s important step towards becoming a climate neutral and fossil-free
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 agreement with Wärtsilä dates back to early
2019, but the project was delayed because of permit applications. Production of
the upgrading unit has been initiated in the fourth quarter of 2020, when also
the orders were included in Wärtsilä’s order book.
The grid aims to become totally green by 2035
Biogas is produced
primarily from waste products, such as manure and food waste. When upgraded to
biomethane, it can be utilised in the same way as natural gas for heat,
powering industrial processes, and as transport fuel. Currently biomethane
accounts for approximately 20 percent of Denmark’s gas consumption, and the aim
is for the grid to become totally green by 2035.
Wärtsilä Biogas Solutions a market leader offering lifecycle solutions to the gas value chain
Solutions is a market leader offering innovative systems and lifecycle
solutions to the gas value chain. Our biogas upgrading plants are based on
Wärtsilä’s Puregas CA technology, an amine scrubber process featuring the
lowest operating costs” commented Arne Jakobsen, General Manager, Biogas
Solutions at Wärtsilä Gas Solutions.
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,” said Jesper Bundgaard,
Executive Vice President at Nature Energy.
The plants will begin injecting biomethane to the Danish gas grid in
The two plants are
to be installed in the towns of Kvaers and Kong, with each plant upgrading more
than 40 million Nm3 of biogas each year. This will deliver some 470 GWh of
green gas energy, equivalent to providing the fuel for more than 45,000 cars.
It is expected that the plants will begin injecting biomethane to the Danish
gas grid in 2022.
