Nordsol, a pioneer in bio-LNG technology, and Prodeval, a leader in biogas treatment and upgrading solutions, have announced their collaboration to construct a cutting-edge bio-LNG production plant in southern Portugal. This plant will serve an esteemed industrial facility in the olive oil production sector, converting organic waste into clean, renewable energy. The facility is set to begin operations in early 2025, marking a significant milestone in sustainable energy for the region and the industry.

Bio-LNG: Fueling the Future

Bio-LNG, or liquefied biomethane, is a renewable fuel that is chemically identical to conventional LNG. Produced through biogas liquefaction, bio-LNG offers a clean alternative to fossil fuels, suitable for long-distance transport and high-temperature industrial processes without the associated carbon footprint. Utilising existing LNG infrastructure, bio-LNG plays a crucial role in reducing greenhouse gas emissions.

From Organic Waste to Energy

The biogas plant and bio-LNG installation will be co-located to maximise the value of organic residues from olive oil production. The facility will produce 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 liquefied biomethane will be efficiently transported to a gasification unit and integrated into the natural gas network, supporting the decarbonisation of high-temperature industrial processes.

Innovative Technology and Strategic Integration

The bio-LNG production process involves upgrading biogas into biomethane using Prodeval’s advanced VALOPUR® membrane technology. This biomethane is then liquefied using Nordsol’s innovative, energy-efficient technology, providing a sustainable alternative to fossil fuels. The biogenic CO2 captured during the process will be liquefied using Prodeval’s V’COOL® FG system and utilised in the food and beverage industry, displacing CO2 from fossil resources.

To ensure peak performance and sustainability, the plant will integrate Prodeval’s systems for biogas upgrading and CO2 liquefaction with Nordsol’s patented technology for biomethane purification and liquefaction. This integration highlights the companies’ commitment to achieving the highest levels of energy efficiency and production reliability. This project marks Prodeval’s third installation for a client in Portugal, reinforcing its regional expertise.

A Commitment to Decarbonisation

The facility represents a robust response to the urgent need for decarbonisation. The bio-LNG and biogenic CO2 produced will be crucial in reducing the carbon emissions associated with industrial processes. By channeling bio-LNG into the national gas network and utilising captured CO2, the project aligns with global efforts to combat climate change and promotes circular economy principles.


“We are pleased to partner with Prodeval, marking the introduction of our cutting-edge biogas liquefaction technology in Portugal. This collaboration showcases our high quality standards, technical expertise, and unparalleled energy efficiency within the industry. This plant not only represents a significant innovation in renewable energy production in this region but also reinforces Nordsol’s dedication to increasing bio-LNG production capacity across Europe.”

  • Léon van Bossum, CEO of Nordsol

“This is fantastic news regarding the implementation of this project in Portugal in collaboration with Nordsol. I’m particularly excited because this project aligns perfectly with our values of promoting the use of biomethane in all its forms. LNG is and will continue to be a significant method for harnessing the potential of biomethane, especially for mobility purposes. I eagerly await its commissioning!”

  • Sébastien Paolozzi, CEO of Prodeval

This groundbreaking project signifies a major advancement in renewable energy production, emphasising both companies’ dedication to innovation and sustainability in the bio-LNG sector.
