Grass as biomass for biogas on the agenda in Denmark

How can crop production contribute more directly to biogas production – while at the same time supporting climate and environmental goals? This question came up repeatedly when farmers, advisors and biogas producers met at Plantekongressen 2026 in Herning and Fjordland Congress 2026 in Skive.

At both Plantekongressen and Fjordland Congress, there was strong interest in solutions that strengthen the interaction between crop production and biogas. The focus was on concrete crops, crop rotations and applications with clear relevance for practical farming.

Grass cultivation as a fast-acting measure in the green tripartite agreement

The presentation “Grass cultivation as a fast-acting measure in the green tripartite agreement” was delivered by Sven Erik Pinstrup from Fjordland and Boe Madsen from Madsen Bioenergi. The presentation focused on grass as a concrete and rapidly applicable tool in the green transition – particularly as biomass for biogas.

Based on fields around the Limfjord, grass was highlighted as a crop that can help reduce nitrate leaching, bind carbon in the soil and support biodiversity, while keeping land in active production.
At the same time, attention was drawn to the role of grass in biogas production and to existing experience with the use of grass as biomass.

The presentation addressed why increased grass cultivation is gaining more attention in the debate, the differences between grass and cereals in cropping systems, and how grass can be integrated into crop rotations and marketed – including for biogas. Concrete examples of both environmental effects and application possibilities were presented.

Living Labs: when knowledge is tested in real life

Accel AgroBiogas works with Living Labs where new solutions and methods are tested in practice in cooperation with farmers and biogas plants. The work is based on concrete field and operational conditions and builds on close dialogue with actors who work with biomass and biogas on a daily basis.

According to Stephan Scheelke, Project Manager at Skive Municipality, the dialogue at the congresses has confirmed that interest in both the project’s Living Labs and grass is recurring among farmers and biogas producers:

“It has been really rewarding to meet farmers and biogas producers face to face and talk about our trial fields. Grass keeps being mentioned as a solution – in relation to climate, environment and biogas,” says Stephan Scheelke.

Stephan Scheelke from Skive Municipality had many good conversations with farmers, biogas producers and advisors – here in Skive, where discussions focused on the economics of biogas.

He also points out that the Skive area has particular strengths when it comes to further developing the link between crop production and biogas:

“The Skive area has had a strong focus on biogas for many years. That is why it makes good sense for Skive Municipality to participate in Accel AgroBiogas and build on both local experience and a strong partnership – not only in Denmark, but also across borders within the project.”
