Denmark Renewable Gas From Waste Market: Market Size & Forecast 2026

Denmark's renewable gas from waste sector represents one of the most mature biogas markets in Europe, with the industry generating roughly $2.8 billion in value during 2025. The country maintains approximately 150 operational biogas plants that convert organic materials including livestock manure, agricultural residues, food waste, and industrial byproducts into methane-rich biogas. Following upgrading to biomethane quality, the gas is injected directly into the national natural gas grid, providing a drop-in renewable alternative for heating, electricity generation, and transportation fuel applications across Denmark.

• •Around 150 biogas plants currently operate across Denmark, utilizing livestock waste as the primary feedstock alongside diverse organic inputs
• •Biogas production has expanded rapidly over the past decade, with output scaling significantly to meet domestic demand
• •The sector feeds upgraded biomethane directly into the Danish gas grid, serving residential, commercial, industrial, and transport end-users

Denmark's national energy policy framework provides the central impetus for market expansion, with official projections outlining pathways to a fully green gas supply by 2030. The regulatory environment supports renewable gas development through feed-in tariffs, guaranteed grid access for biomethane injection, and mandates requiring increasing shares of renewable gas in the overall energy mix. At the European level, EU climate targets and the REPowerEU initiative have elevated biogas as a strategic pillar for energy security and decarbonization, accelerating investment flows into Danish biogas infrastructure.

• •National strategy targets 100 percent green gas supply by 2030, creating a clear policy roadmap for sustained sector investment
• •EU-level climate obligations and REPowerEU objectives position renewable gas as essential to European energy independence goals
• •Livestock manure provides a particularly abundant and underutilized feedstock in Denmark's agricultural sector, supporting cost-competitive production economics

The Danish renewable gas market spans several feedstock categories and technology platforms, with agricultural biogas plants dominating the landscape. Manure-based digestion facilities represent the largest segment, leveraging Denmark's substantial livestock population, while dedicated energy crop co-digestion and food waste-to-biogas projects supplement output. Geographically, plant distribution reflects Denmark's agricultural heartland, with concentrations in Jutland and on the islands where livestock farming intensity is highest.

• •Livestock manure remains the dominant feedstock, though co-digestion with energy crops and organic household waste is expanding
• •Medium-scale centralized plants increasingly complement smaller on-farm digesters, optimizing logistics and processing efficiency
• •Regional plant density correlates with agricultural intensity, particularly across central and western Jutland farming regions

What are the recent trends and outlook?

Looking forward, the market trajectory points toward continued capacity additions through the end of the decade, with biomethane injection volumes expected to climb further as Denmark progresses toward its 2030 green gas target. Technological advances in pre-treatment processes, co-digestion optimization, and carbon capture integration are improving plant economics and environmental performance. The sector also benefits from growing demand for renewable gas in heavy transport and industrial applications that cannot easily electrify, broadening the addressable market beyond traditional gas grid injection.

• •Biomethane injection rates are projected to increase toward 2030 as additional capacity comes online and existing plants are upgraded
• •Carbon capture and storage integration with biogas production is emerging as a pathway to achieve negative emissions alongside renewable gas output
• •Expanding demand from the transport sector, particularly heavy-duty vehicles and shipping, is creating new offtake channels beyond conventional gas grid sales
