National Grid Report Pushes for Anaerobic Digestion and Gasification for Biomethane into UK Gas Grid

National Grid presents biogas report to UK government

(First posted 02/02/2009)
Half Britain's homes could be heated by renewable gas, says National Grid in a report it has presented to the UK Government.

The report looks at how all the biodegradable waste streams such as sewage, food and wood could be turned into biogas and injected into the gas distribution system.

Biogas is produced by two main processes. Anaerobic digestion which turns wet waste such as sewage and animal manure into biomethane and gasification which is better suited to drier wastes and energy crops. Biomethane is already being produced and injected into the gas grids in Europe.

It is estimated that biogas would be a similar price to other renewable energy sources. However because the country already has an extensive gas grid, there would be little need for disruptive infrastructure development or any major inconvenience to consumers in their homes or streets.

The report concludes that there are no insurmountable technical difficulties to delivering biogas. The main hurdle will be about getting the right commercial incentives in place so waste can be turned into biomethane for gas grid injection rather than electricity. This needs to be allied with a comprehensive waste management policy.

A copy of the report can be found in the Publications section of the National Grid web site.

Steve - This is one BIG and welcome turnaround! for the UK gas suppliers to, for the first time, welcome biomethane from Anaerobic Digestion Plants into the natural gas distribution system

Renewable natural resources are those that, with proper care can be maintained or even increase. The main renewable resources are plants and animals. In turn the plants and animals depend for their livelihood on other renewable resources are the water and soil. Although water is abundant, it is not permanent resource since it is easily contaminated. Once contaminated it is very difficult to restore water purity
