Towards a biobased economy: co-digestion within the north sea bio energy project

Climate change, diminishing supply of fossil fuels and the wish to become independent of politically unstable regions, stimulate the development and use of bioenergy. Political ambitions for the development of bioenergy exist on international, national, and regional level. The production of bioenergy contributes to the transition towards a biobased economy. This transition will take many years, and requires investments of different stakeholders over time. A good example of an international partnership to increase the use of biomass for energy production is the North Sea Bio Energy project. The North Sea Bio Energy (NSBE) project was an initiative where stakeholders collaborated to increase the use of biomass for energy production. The NSBE project (2004-2008) was part of the Interreg IIIB programme for the North Sea region and was led by the province of Fryslan (The Netherlands). The project covered four themes: production of biomass for bioenergy, the use of biomass for biogas production, the use of biomass (specifically wood) for heat production and the development of a virtual marketplace for biomass. The Animal Sciences Group contributed to the theme biomass for biogas production. Overall aim of the North Sea Bio Energy project was to increase the use of biomass for energy purposes on regional level and subsequently contribute to the reduction of greenhouse gas emissions. This was aimed for by generating new knowledge and exchanging existing knowledge between partners and by introducing regional pilots to show the possibilities of biomass and bioenergy production. This paper focused on research performed within the theme use of biomass for biogas production and included the following activities:

• The evaluation of biomass as co-digestion material together with animal slurry

• The use of digested slurry as organic fertilizer on grassland

• Inventory of perspectives for biogas on regional level and incentives and bottlenecks for implementation

• Monitoring of existing and possible new biogas installations
• Knowledge dissemination through study groups.

 

 

Stand der Pumpspeicher in Deutschland 2025

Infolge des Ausbaus der Stromerzeugung aus erneuerbaren Energien ist ein erhöhter Speicherbedarf im Stromverbundnetz notwendig. Hierdurch steigt die Bedeutung von Pumpspeichern als bis auf weiteres einzige Möglichkeit für eine großmaßstäbliche Stromspeicherung.
