How does lagoonQUBE work?

Agricultural slurry and waste water lagoons create anaerobic conditions where methane and carbon dioxide (biogas) are naturally produced. This is normally released into the atmosphere wasting a valuable fuel resource as well as releasing a potent greenhouse gas.

LagoonQUBE is designed to perform the dual purpose of capturing the biogas on existing slurry lagoons with the added benefit of also collecting rainfall and so reducing storage volume. The collected biogas can then be used for heat and power generation.

LagoonQUBEs are lightweight inflatable modules designed to float on the surface of the existing lagoon and collect and capture the rainfall and biogas produced. Each lagoonQUBE is a hexagonal module measuring 94m2 and having a diameter of 11.6 metres. The hexagonal design means that the lagoonQUBE’s fit together in any number and can cover as much of the lagoon surface as required.

In storage tanks the lagoonQUBE can be manufactured to fit the size of the internal diameter of the existing circular slurry store or tank.

The lightweight modules are assembled on the side of the lagoon and then easily pulled on to the surface where they are floated into place and tethered. The natural processes of anaerobic digestion taking place in the slurry lagoon releases methane and carbon dioxide which are captured by the lagoonQUBE and piped away to be used.

Biogas production will vary depending on the composition of the slurry it is covering.
