Investments in biogas mean investing in energy security of supply and ensuring a stable energy system against the intermittency of renewables as well as reducing the agricultural climate budget.
The sustainable alternative to natural gas
Biogas produced from organic waste such as manure and sewage is a low-cost fuel that can be used as an alternative to natural gas for both heating and electricity. The production of biogas reduces emissions of CO2 and other greenhouse gases, as well as reducing water pollution from nutrient run-off.
From waste and residues to biogas
Conversion of biomass to biogas comprises agricultural residues and industry waste, and Denmark hosts two types of biogas plants:
- Joint biogas plants, which receive manure and waste from a number of farms, as well as industrial and household waste. The gas produced in these installations is sold to local CPH plants.
- Farm biogas plants, which utilise the waste from a single farm, mainly manure.
Injecting biogas into the natural gas grid
In terms of biogas utilisation, Denmark has a strong infrastructure for utilising biomass in biogas plants, and the first upgraded biogas from slurry was injected into Danish natural gas grid in January 2014. The goal is to distribute the upgraded biogas throughout the natural gas grid within the next 3-5 years, able to reach 250,000 natural gas consumers.
