First Biogas from Slurry Injected into Danish Natural Gas Grid

By State of Green | [email protected]
8 January 2014
Upgraded biogas produced from pig and cattle slurry and manure from poultry, mixed with grass and straw, has been distributed through the Danish natural gas grid. 

 

Previously biogas from slurry has only been utilised by decentralised CHP plants in Denmark, even though neighbouring countries such as Germany and Sweden already distribute it to their citizens.  

 

With the expansion into the Danish natural gas system a much greater share of Denmark’s slurry can be utilised for energy. 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. 

 

The first upgraded biogas is produced by LBT Agro, which is set to deliver 6 million m³ a year, corresponding to heating of 4,000 single-family houses. In terms of carbon dioxide emissions, this generates annual savings of around 12,000 tonnes. 

 

Denmark already uses upgraded biogas in the natural gas grid but this gas is produced from household sludge and not slurry, as is the current case.
