COASTAL Biogas application submitted

Today the COASTAL Biogas application was submitted by the lead partner, FNR, to the South Baltic Sea Programme.

COASTAL stands for Cluster On Anaerobic Digestion, Environmental Services and NuTrients RemovAL, and is focused on anaerobic digestion of cast seaweed in combination with digestate utilization as bio-fertilizer.

The project consortium consists of 20 partners out of which 6 are full project partners and WP-leaders;
FNR (DE) – lead partner
Gdansk University of Technology (PL)
Baltic Energy Innovation Centre (SE)
Rostock University (DE)
Roskilde University (DK)
Lithuanian Energy Institute (LT)

The proposed budget is close to 1.6 MEUR and covers lab scale and pilot testing, best practice and lessons learned, feasibility studies in close collaboration with partners able to implement the investigated technology and massive dissemination activities including 5 conferences and study tours.

Expected project start is 1 July 2018 and project end 30 June 2021.

3 more organisations join COASTAL Biogas

Innovations- und Bildungszentrum, IBZ, InterCenter GmbH, Abt. Ernuerbare Energie and IBKE, Institut für Biogas, Kreislaufwirtschaft & Energi have joined COASTAL Biogas as Associated Partners.

The project consortium consists now of 17 partners and 3 subcontractors. The majority of the partners are stakeholders able to implement technological advances related to anaerobic digestion of cast seaweed and digestate utilization developed within the project. More than 40 municipalities are represented directly (as subcontractors and Associated Partners) or indirectly through other organisations such as Biogas Syd (owned by 33 municipalities in Sweden).

The application will be submitted shortly (deadline 20th of December).

Seminar presentations are now online

The Pre-BASIC Biogas Seminar attracted 65 participants from 11 countries.

A snapshot of the audiance, eager to hear more about anaerobic digestion and digestate utilization as means to mitigate eutrophication in the Baltic Sea basin.

12 presentations were given by national and international experts. Focus was on

  • anaerobic digestion of manure and digestate utilization
  • aquatic substrates
  • upgrading of biogas including technology presentations by ETW Energietechnik GmbH, Pentair Haffmans and Hitachi Zosen Inova BioMethan GmbH


Dr. Knud Tybirk, Samsø Municipality gave a presentation on the results and recommendations from the Baltic Manure project and  Danish biogas results from 2016 on manure co-substrates.

Desirée Grahn, Director of Biogas Syd, gave a presentation on the ongoing Biogas 2020 project and results from the recently finished BIOGASSYS project.

Thies Fellenberg
Thies Fellenberg, Fachagentur Nachwachsende Rohstoffe (FNR) gave an overview of biogas upgrading in Germany.

The seminar chairman, Jörgen Held, concluded that even if manure is used in many commercial installations it’s evident that just a small fraction of the potential is utilized. Anerobic digestion of aquatic substrates has been discussed for several years and it’s good to see that seaweed now is starting to be used in industrial scale plants such as the Solrød biogas plant in Denmark and that we are just in the very beginning of an interesting development. These observations are also good indications that the BASIC Biogas efforts on manure and aquatic substrates in combination with digestate utilization as means to reduce the eutrophication in the Baltic Sea area are spot on.

Study tour to a combined ethanol, biogas and CHP facility

On the 6th of August a study tour to a combined ethanol, biogas and CHP facility in Piaszczyna took place. The facility is highly integrated. Ethanol is made of corn and the residues are digested in two anaerobic digestors. The biogas is used for electricity production and to provide heat for the destillation process as well as for drying and heating the digestors which operate at approx. 40 °C. Process water is to be cleaned in an algae cultivation in order to close the water loop and provide additional substrate to the anaerobic digestors. Finally the digestate is dried and used as a fertilizer. In this way the nutrients and water loop are closed and the facility produces no waste streams at the same time as a high energy efficiency is obtained.

The biogas is used for CHP production in two Jenbacher gas engines.
