Local Generation’s big biogas bag

November 29, 2011

The latest landmark to be put in place at Local Generation’s anaerobic digestion (AD) plant in March, Cambs, is the impressive biogas dome. Made from the same sturdy stuff that’s used to float lifeboats in stormy seas, the container is designed to store almost 4000 cubic metres of biogas.

Around 60% methane and 40% CO2, biogas is the end product of the AD process.  However, it doesn’t stop there.  The big white dome simply holds the biogas until it’s ready to go to the combined heat and power engines that will convert it into green electricity, for use at sister company Fenmarc and to be fed back into the national grid.

We’re on track for commissioning the plant in the next couple of weeks and fully up and running early next year.
