Nordsol, Prodeval to build bio-LNG plant in Portugal

Nordsol, a bio-LNG technology provider, and Prodeval, a developer of biogas treatment and upgrading solutions, plan to construct a bio-LNG production plant in southern Portugal, the companies said on May 15. 

The new plant will serve a facility in the olive oil production sector, utilising their organic waste to create renewable energy. This facility is poised to commence operations in early 2025. 

The co-location of the biogas plant and the bio-LNG installation optimises the utilisation of organic residues from olive oil production, enhancing operational efficiency while minimising waste. The facility is projected to yield 10 tonnes of bio-LNG and 21 tonnes of biogenic liquefied CO2 daily from 1100 nm³/h of biogas, primarily sourced from olive wastewater. 

The production process involves technologies from both Nordsol and Prodeval. Prodeval's membrane technology upgrades biogas into biomethane, which is then liquefied to bio-LNG using Nordsol's expertise. Furthermore, Prodeval's system captures biogenic CO2, which will be liquefied and utilised in the food and beverage industry, displacing CO2 from fossil resources.

Bio-LNG, or liquefied biomethane, is a renewable fuel that is chemically identical to conventional LNG. Produced through the liquefaction of biogas, bio-LNG serves as a clean alternative to fossil fuels, capable of powering long-distance transport as well as high-temperature industrial processes without the carbon footprint associated with fossil energy sources. Because it makes use of existing LNG infrastructure and technology, bio-LNG is playing an important role in the reduction of GHG emissions.
