Finland-headed gas and energy company Gasum Oy has revealed that planning work on a "Big Five" biogas plant in the Swedish municipality of Hörby is proceeding at pace and in good cooperation with the local authorities.

Gasum has an ambitious plan to construct five large-scale modern biogas plants in Sweden in the coming years.

These, the “Big Five”, are an important part of the company’s plan to significantly increase the availability of biomethane aka renewable natural gas (RNG) in the Nordic countries.

Two of the planned Big Five plants are already under construction. The first plant in Götene, some 150 km northeast of Gothenburg, will start commercial production at the end of 2024.

The second one in Borlänge, approximately 200 km northwest of Stockholm, received a final investment decision at the beginning of 2024 and onsite work is being started.

Hörby selected for the third Big Five plant

The next plant will be located in Hörby, in southern Sweden about 50 km northeast of Malmö.

Planning is proceeding at pace, as most design solutions are already being tried and tested in the Götene and Borlänge projects.

That said, each site is unique regarding the conditions and regional characteristics,

Hörby is located in the Skåne region and is characterized by a high density of agriculture and livestock farms. This means that there is an abundance of manure and other agricultural residues that can be used to produce biogas, and correspondingly, biogas production can reduce the climate impact of agriculture in the region. We have a very good relationship with the Hörby municipality, which has a positive outlook on Gasum’s planned project – our cooperation in developing the land use plan is working very well, said Tor Husebø, VP of Projects and Biogas Production at Gasum.

Strategic location

According to the company, biogas made from waste streams is a fuel that produces on average 90 percent fewer life cycle greenhouse gas (GHG) emissions when compared with traditional fossil fuels, such as diesel.

Refueling bioLNG at Gasum’s LNG/bioLNG station in Västerås, the first such Gasum gas refueling station to open in Sweden.

When using animal manure from farms as raw material, the reduction can be more than 100 percent as emissions from traditional manure handling are avoided.

This is why increased biogas use is one of the most impactful ways to reduce emissions from transport and industry – it’s a solution that is readily available.

The planned location of Gasum’s biogas plant in Hörby is right next to the E22 highway making the location ideal regarding transport infrastructure.

The planned plant would be able to receive up to 500,000 tonnes of a wide range of raw materials annually.

The feedstock would consist of primarily residual products from the agricultural sector such as solid and liquid manure from livestock farms, grain, and silage.

In addition to biogas that will be upgraded to biomethane (aka RNG), the plant will produce up to 480,000 tonnes of high-quality recycled biofertilizers annually that will be returned to the surrounding farm fields for growing crops.

Progressive planning process

While Gasum has yet to make a final investment decision (FID), the planning process is firmly proceeding to secure all necessary permits and the land use plan with the municipality.

Like the other Big Five plants, the Hörby plant project has been granted funding from the Swedish Environmental Protection Agency’s Climate Step (Klimatklivet) investment program.

If everything goes as planned, the plant will start producing 133 GWh of biomethane per year from the end of 2026. That means a substantial reduction in carbon dioxide emissions enabled by using biogas instead of fossil fuels, Tor Husebø said.

Gasum’s strategic goal is to bring seven terawatt hours (7 TWh) of RNG annually to the Nordic market by 2027.

This is four times more than today and would mean a combined annual carbon dioxide (CO2) reduction of 1.8 million tonnes for Gasum’s customers.
