Wärtsilä has been awarded a major contract to supply and build a plant in Cologne, Germany, for the production of CO2-neutral liquid transport fuels
The plant will liquefy gas from the natural gas grid to produce carbon-neutral bioLNG and will have a capacity of approximately 100,000 tonnes per year.
Wärtsilä vice-president for gas solutions Antti Kuokkanen said “The use of LNG as an emissions-reducing fuel in the marine and transportation industries is already well established, and to introduce bioLNG which can be mixed with LNG is the next obvious step in enabling a CO2-neutral transportation fuel. We look forward to continuing on our mission to enable sustainable societies with smart technology.”
The feedstock for bioLNG – based on biological waste material – is fed to an anaerobic digestion reactor that produces biogas which is then upgraded to biomethane and injected into the natural gas grid.
Wärtsilä said ‘green gas’ certificates are issued along with the injected biomethane, which then permits operators at other locations, such as liquefaction plants producing bioLNG, to buy these certificates and utilise the biomethane.
Wärtsilä’s participation in the project will include engineering, civil works, installation, and commissioning of the plant. The plant will include a gas treatment system based on the company’s Puregas technology, a liquefaction unit utilising the Semi-Dual Brayton technology, storage tanks, truck filling stations, and all necessary safety flare and auxiliary equipment.
The order with Wärtsilä was placed in September 2020 and the plant is expected to be fully operational by Q3 2022.
