In Sweden, Biogas Västra Skaraborg AB (BVS) has held a groundbreaking ceremony marking the launch of the construction phase of a biogas-to-liquefied biomethane (bioLNG) plant in Vara. For the Netherlands-headed liquefaction technology provider Nordsol, it marks the company's first bioLNG project in the country.
Biogas Västra Skaraborg (BVS) is a special-purpose company, founded and owned by 113 farmers and local entrepreneurs, to build, own, and operate a biogas plant that will produce up to 70 GWh per annum of bioLNG.
Held on September 24, 2025, the groundbreaking ceremony marks the start of construction for the plant, with commissioning planned for 2026.
Locally sourced feedstock
BVS will collect both liquid and solid manure from farms across the municipalities of Grästorp, Essunga, and Vara.
In total, the plant will process around 370,000 tonnes of manure per annum as feedstock for biogas production.
The biogas will be upgraded and liquefied into bioLNG with the support of two technology partners, EnviTec Biogas and Nordsol, respectively.
The bioLNG will be distributed by Redo Biosolutions AB, which will use it to decarbonise road transport in Sweden.
With this project, we are jointly fostering rural development and unlocking the vast potential of bioenergy production for the transport, maritime, and industry sectors. Together with EnviTec, Nordsol, and our other partners, we are making our Fully Green LBG available in the whole Nordics, said Tomas Carlmon from Biogas Västra Skaraborg AB.
Integrating upgrading and liquefaction technologies
EnviTec Biogas will deliver its EnviThan upgrading technology to convert the raw biogas into biomethane. Nordsol’s Core technology will then take over, further purifying and liquefying the gas into bioLNG.
With the plant we are delivering for BVS, we will produce up to 70 GWh of biomethane per year – a real milestone for us in the Swedish market, said Maurice Markerink, Managing Director of EnviTec Plant Construction.
The systems will be tightly integrated to ensure low energy consumption, prevent methane slip, and facilitate easy and reliable operation, all within a compact footprint.
This project marks our first step into Sweden – a country with a strong vision for sustainable mobility. It’s a privilege to support Biogas Västra Skaraborg AB and its network of farmers in turning local waste streams into clean transport fuel. Our LBG technology helps create real value from biogas; for climate, for transport, and for the local community. LBG is now, said Léon van Bossum, CEO of Nordsol.
In total, the biogas plant features a digester capacity of nearly 32,000 m³. When manure from different farms is mixed, hygienization is required.
After the two fermentation stages, the material must remain isolated for ten hours in a tank heated to more than 52 °C.
To ensure optimal retention times for the different feedstocks, the planned five digesters of the facility will be fed separately, Maurice Markerink explained.
The digestate is then pumped into a storage tank. To ensure high energy efficiency, the plant is equipped with heat exchangers that cool the digestate before it enters the storage tanks while simultaneously heating the incoming manure.
Additional heat demand is met by industrial heat pumps, which, in combination with heat recovery, reduce overall energy consumption and improve the biomethane’s carbon intensity (CI) score.
The EnviThan gas upgrading plant is designed to produce up to 70 GWh of biomethane per year for the production of bioLNG. Nordsol’s process allows for further purification and robust biomethane liquefaction.
Our EnviThan technology upgrades the biomethane to 98 percent methane (CH4). With Nordsol‘s patented Flash-2-Sweep technology, the performance of membranes increases 20 times, resulting in liquefaction-ready biomethane without the need for molecular sieves or chemicals. Their technology is tightly integrated with the EnviThan upgrading plant for optimal operability and energy efficiency, Maurice Markerink said.
This setup is ideally suited for decentralised bioLNG production, right at the source of the feedstock.
Nordsol’s LBG technology stood out as the most robust solution with the best business case for our project. Its low energy consumption, high reliability, and ability to deliver consistently cold LBG of -160°C are all critical to operating in the Swedish market. We’re excited to partner with Nordsol’s experts and bring this important facility to life together, Tomas Carlmon said.
Investment support
The large-scale BVS project is supported by the Swedish climate investment scheme Klimatklivet (Climate Step).
Administered by the Swedish Environmental Protection Agency, the program supports investments that result in a permanent reduction of greenhouse gas (GHG) emissions in Sweden, particularly in transportation, energy and heating, agriculture, and the use of waste and residues for biogas.
The level of support is determined by the project’s climate benefit, with priority given to measures that achieve the greatest and most cost-effective reduction of greenhouse gas emissions.
