Energy farm in Abony

The energy farm embraces the biorefinery concept: dedicated crops and residues are processed into energy carriers through various, interlinked conversion platforms. This creates closed loops in by-product and waste utilisation among the farm components, minimizing environmental emissions and fossil energy inputs. The farm operates 3000 ha of cropland, producing mainly feed for a dairy operation (2000 heads of cattle). The manure is processed in anaerobic digesters (AD) to biogas, which is combusted in a 640 kW CHP plant. Power is fed to the grid, heat is used internally, to maintain AD temperature and for the future distillation process, as well as in greenhouse production. DGs from ethanol production will be fed to cattle to augment their protein diet. The accelerated composter closes the loop, where all remaining residues are treated and processed into a valuable market commodity. The process results in significant production cost cuts, through energy savings, rationalisation of production and carbon emission offsets.

Positive experiences:The energy farm concept is being multiplied in Hungary, a clear sign of success. The economic viability of the whole operation increases as there are variable output options for an input mix that is vulnerable to external price drivers.
Negative experiences:Supplier selection and scheduling is a crucial aspect that can cause major delays and set-backs. Implementing such projects in time of a global financial recession was a major challange.
