Objective
To demonstrate in an agricultural community, a self-sufficient energy system based on biogas generated from the community's own animal and agricultural wastes.
Plant expansion is in operation. The gas piping system now extends to the whole village. The natural gas/air mixing station is also finished and operational. 68 consumers have converted from heating oil to gas.
The demonstration site is one of intensive agriculture and animal husbandry. The project is designed to produce 750,000 m3 of biogas annually.
Manure and other waste is collected within a three kilometer radius of Revninge. It is then stored and heated to 35 C in a 400 m3 tank, then processed in a digester unit. Ten insulated concrete digester tanks each of 240 m3 capacity are planned.
The gas production cycle requires 45 days and an 80 % gas yield is projected. The digesters will operate in batch due to the high content of straw and other solids in the waste mixture.
The biogas will be piped to all homes in Revninge and to a boiler station which will produce hot water for heating of the waste in the initial stage of the process. Up to 1 day's gas production will be stored. Slurry is also to be produced by the digester process and stored in a 8,500 m3 tank, to be used as fertilizer when required.
An important aspect of the project concerns the social acceptance of the centralizedbiogas plant : acceptance by the local authorities, acceptance of the distribution network as well by farmers as by non farmers of the community, acceptance of the produced biogas in the national natural gas distribution grid.
