Lord Redesdale – Anaerobic Digestion and Biogas Association

That was according to Lord Redesdale, chair of the Anaerobic Digestion and Biogas Association, speaking at Reaseheath.

He said he could foresee a network of alkathene plastic pipes linking slurry stores in local networks supplying gas to energy buyers.

Too much focus is on generating power from AD, he said, when it could pay producers not to pump slurry but to capture its natural ability to produce gas.

Gas capture viability

Currently, natural gas is worth 4p a therm, although 8-10p would be more reasonable. At that price capturing gas was viable, said Lord Redesdale. Supplies could then be pumped from local slurry stores to strategically placed scrubbing plants before eventually entering the local domestic gas network.

Mapping of potential farm slurry suppliers would be key to establishing efficient, cost effective networks.

Given many slurry stores may need updating and, indeed, covering to reduce gas emissions by 2011, it made sense to ensure any investment now could tap into potential income streams of the future, he said.
