Renewable Energy Focus - 29/12/09

The Anaerobic Digestion and Biogas Association (ADBA) predicts that farmers, commercial operators and local authorities will build 1000 anaerobic digestion biogas plants in the next five years at a cost of £5 billion, mostly funded by the private sector.

The anaerobic digestion biogas plants could meet two thirds of Britain's renewable energy targets by 2020, ADBA says.

I hope this right - good news!! Particularly if the 10% figure is correct (sounds high to me?)

I guess the only question is whatever is being used for the bio gas is now not used for something else. Will that be replaced by something else that is fossil fuel related?

Much of what will be used goes onto the land already as either undigested slurry or Farm Yard Manure (FYM). Digesting it takes some of the carbon and hydrogen out of the waste, as methane, before it is put onto the land as a fertiliser and reduces the amount of methane given off from the land.

The farm base digesters can also take biodegradable household waste and reduce the amount of methane given off from landfill. This also will reduce the amount of compost available slightly by diverting it to the agricultural sector where it will reduce the amount of artificial fertilisers used.

Great for the farmyard but I get suspicious about the ones that are promised that'll run on "food waste" (collected from people's houses).

Here at Chateau Renewable we probably chuck away less than 100g (dry) of food waste per day, that's about 0.4 kWh of heat if you burn (dry) or digest (wet) it aIui.

In a thermal power plant, 0.4 kWh of heat will produce about 0.1 kWh of electricity. That'll just about keep my pc running for long enough to finish this me
