Finland’s Wartsila will go ahead with the construction of a liquid biogas (bioLNG) plant in Asker, in Norway. Announcing it had received notice to proceed – signed in December 2018 – on March 13, Wartsila said the contract for the plant had been awarded in April 2018. The plant will produce 20 tonnes per day (7,300 tpy) of bioLNG.
The contract was awarded by VEAS, a Norwegian wastewater treatment and biogas producer. The plant will upgrade biogas, which will then be liquefied. The new plant builds on the existing biogas plant, which is the largest sewage sludge treatment plant in Norway.
BioLNG from the plant is vehicle quality, with Wartsila saying VEAS would benefit from an alternative to fossil fuels and a reduction in CO2 emissions. Work on the project will also include water production, storage and truck-loading capabilities.
The plant is scheduled to be completed within 14 months, targeting commercial operations in 2020.
“Wartsila has the experience and technical know-how needed to integrate the new bioLNG facility with our existing plant,” said VEAS’ managing director, Ragnhild Borchgrevink, going on to say the builder was “capable of meeting our demanding time schedule”.
“Efficiency and environmental sustainability are two of the main pillars of Wartsila’s strategy for future energy use. This new plant represents both of these pillars,” said Wartsila’s biogas liquefaction head, Arne Jakobsen.
Wartsila has a number of bioLNG projects under its belt, aided by its acquisition of Puregas Solutions in October 2017. Europe is particularly keen on the technology but has struck deals in other areas, including Indonesia. BioLNG facilities are all fairly small – Wartsila offers capacities of up to 50 tonnes per day (18,250 tpy) – but attractive, as the produced gas qualifies as a renewable fuel.
In March 2016, Wartsila announced a contract to build a bioLNG plant at Skogn, in Norway, with capacity of 25 tonnes per day (9,125 tpy). The plant opened officially opened in September 2018 and was said to be the largest in the Nordic countries.
Further good news for bioLNG came in February, when Shell Ventures signed up as a strategic investor in Nordsol, a company focused on converting biogas into bioLNG for the transport sector.
