Chesterfield BioGas to supply UK’s first biogas upgrade plant to Centrica


Chesterfield BioGas Ltd (CBG) has announced an order from Centrica plc, the owners of British Gas, to supply one of the UK’s first biogas upgrading plants.

The new plant will produce clean biomethane, for direct injection into the national gas grid for use by all consumers.

Biomethane is similar in its properties to the natural gas currently supplied through the grid, except that it is generated from organic waste products such as cattle manures, horticultural, food and household waste. In this particular case, the source is biogas naturally produced during wastewater treatment at the Didcot sewage works of Thames Water in Oxfordshire.

The order, worth in excess of £600,000, has resulted from a partnership between Centrica, Thames Water and Scotia Gas Networks – the installers of the raw biogas collection equipment. CBG has been working with the partnership to integrate the upgrading unit into the overall system. Currently, a proportion of the gas from sewage processing at the site is flared to the atmosphere.
