Wärtsilä to supply major LNG/bio-LNG production plant for transport fuels

Wärtsilä has been awarded a major contract to supply and construct a plant for the production of carbon-neutral liquid transport fuels.

The plant will liquefy gas from the natural gas grid to produce carbon-neutral LNG/bio-LNG. It will have a capacity of approximately 100,000 tons per year and will be built in Cologne, Germany.

“It’s an honour to have been awarded this order for a landmark project,” said Antti Kuokkanen, vice-president of gas solutions at Wärtsilä. “We take this as a clear endorsement of Wärtsilä’s capabilities in this field.

“The use of LNG as an emissions-reducing fuel in the marine and transportation industries is already well established, and to introduce bio-LNG which can be mixed with LNG is the next obvious step in enabling a carbon-neutral transportation fuel. We look forward to continuing on our mission to enable sustainable societies with smart technology.”

The feedstock for bio-LNG is based on waste material such as liquid manure and food waste. The feedstock is then processed using anaerobic digestion to produce biogas, which is then upgraded to biomethane and injected into the natural gas grid.

Green gas certificates are issued along with the injected biomethane, which then permits operators at other locations, such as liquefaction plants producing bio-LNG, to buy the certificates and utilise the biomethane.

The plant will include a gas treatment system based on Wärtsilä’s Puregas CA technology, a liquefaction unit using Wärtsilä’s Semi-Dual Brayton technology, storage tanks, truck filling stations, and all necessary safety flare and auxiliary equipment. The plant is expected to be fully operational by autumn 2022.
