Algae for Biogas in Central Denmark Region

Algae for Biogas in Central Denmark Region is a 3-year project (2010-2013) funded by Central Denmark Region´s Growth Forum, EU´s 7th Framework Programme and other project partners.


Purpose of the project

The main goal of the project is to establish and manage a land-based test and demonstration plant for cultivating algae in Grenaa, Denmark and find the best ways to make the most biogas out of macro algae. Likewise, the project has established a business network with an industry and SME´s with an interest in algae.


Project partners

Danish Technological Institute, Aarhus University, DONG Energy A / S, Kattegat Centre, Ocean Centre Denmark and AkvaGroup.


Project objectives

  • Establish algae cultivation and research facility in Grenaa
  • Identify, optimize and demonstrate the production of the most optimal Danish species of macro algae for the production of biogas
  • Develop and demonstrate existing and new technology for production of biogas from aquatic biomass
  • Develop and demonstrate technologies for harvest, preparation and characterization of aquatic biomass, including thermal and enzymatic treatment with REnescience technology
  • Establish a realistic scenario for algae cultivation large scale in Denmark
  • Participate in a business cluster initiated in Ocean Centre Denmark focusing on the commercialization of energy and high-value products from algae
  • Identification of opportunities and potentials for industrial development including arranging annual workshops where industry, research and technological service institutes to exchange knowledge


Conclusions in short


  • Indeed, good opportunities to use algae to produce sustainable energy in the form of biogas
  • Residue from the biogas production is suitable as a fertilizer
  • Algae effectively absorbs nutrients from slurry and wastewater and CO2 from flue gas. Therefore, algae can be used as a biofilter.
  • Algae contains valuable protein that can replace any of the protein in animal feed. Protein in conventional animal feed often derives from imported soya and it harms both the environment and climate.


Another important goal of the project was to examine if the cultivation and use of seaweed could create new businesses and jobs in Central Denmark Region.


To map the potential AlgaeCentre Denmark has initiated both large and small algae projects in Central Denmark Region, with more than 20 different companies, conferences and business workshops. A lot of those companies and other companies in Europe have shown interest in taking part in the industrial development.


The conclusion is that cultivation of algae can become a huge industry but there is still research and development work to be done in order to obtain this position.
