Task 37 of the International Energy Agency has just published a report entitled ‘Exploring the viability of small scale anaerobic digesters in livestock farming’ written by AD Network member Dr Clare Lukehurst, OBE and AD Network co-manager Angela Bywater.
For those of you not aware of this, the IEA Task 37 website has a number of useful resources, not least of which are the Country Reports which summarise activity in member countries over the given period.
Task 37 members recently published an annual summary of their Country Reports for 2014. The individual country reports include information on the number of biogas plants in operation, biogas production data, biogas utilisation, number of upgrading plants, number of vehicles using biomethane as fuel, details of financial support mechanisms and some information on key national research and development projects.
Task 37 recently published a technical brochure on “A perspective on the potential role of biogas in smart energy grids”. Increased generation of electricity from wind and solar installations is leading to challenges in terms of balancing electricity demand with supply and managing the increasing occurrences of surplus electricity. Biogas systems can facilitate increased proportions of variable renewable electricity on the electricity grid mainly through use of two different technologies: demand driven biogas systems which increase production of electricity from biogas facilities at times of high demand for electricity, or temporary storage of biogas at times of low electricity demand; and power to gas (P2G) systems when demand for electricity is less than supply of electricity to the electricity grid, allowing conversion of surplus electricity to methane.
