Denmark has become a world leader in biogas and biomethane thanks to a long-term strategy based on technological innovation, efficient utilization of byproducts, and consistent political support.
The country already injects 40% of its gas into its grid in the form of biomethane and has set the ambitious goal of covering 100% of its natural gas consumption with this source by 2035. Its experience and model are being presented at the Renewable Gas Show.
At the national stand, coordinated by the Danish Export Association, a group of Danish companies will showcase their advanced solutions and technologies covering the entire biomethane value chain, from raw material pretreatment to digestate treatment:
- A-Consult: digesters and prefabricated concrete tanks for storing slurry and digestate.
- Active NS: clay-based additive that optimizes slurry management and biogas production.
- Ammongas: Amine upgrading technology to efficiently convert biogas into biomethane.
- Euromilling: equipment for the treatment of biochar and the pretreatment of straw intended to produce biogas.
- Hexa-Cover: floating cover for ponds and tanks for slurry, liquid fractions and digestate.
- Linka Energy: biomass boilers for the generation of thermal energy in biomethane plants.
- Purfil: Comprehensive system for separating and treating digestate, with production of fertilizers and water.
- Runi: pretreatment solutions for remains with high liquid content and for dehydrating the digestate.
Biogas has been a priority in Danish energy policy for more than four decades. In parallel, Danish technologists have developed solutions that stand out for their reliability and efficiency, installed in Denmark and numerous international markets. Their knowledge and experience make Danish technology a guarantee for the technical and economic viability of any biogas or biomethane project.
With an area similar to that of Extremadura, Denmark currently has approximately 160 biogas plants that collectively produce 32 PJ annually. Around 60% are agro-industrial facilities that use livestock manure and other organic byproducts, accounting for more than 90% of the biogas generated in the country.
Most of these high-capacity plants produce biomethane for injection into the grid and operate as genuine organic waste treatment centers. The resulting digestate is routinely applied to fields as fertilizer.
Denmark's vision for biogas is characterized by its holistic, rational, and long-term approach. The results speak for themselves: it is the country in the world with the highest percentage of biomethane injected into the grid, at 40%, and aims to reach 100% in just a decade. In the last three summers, there have even been days in July when biomethane production exceeded the country's total gas consumption.
The graph illustrates the monthly evolution of biomethane's share in national gas consumption over recent years.
