Biogas 21 – Plaxton Bridge

Project Description

Plaxton Bridge, located near Hull (UK), is Solar 21’s first anaerobic digestion project. The plant will produce between 4 million and 5.4 million cubic metres of biomethane gas, enough for 3,700 homes.

Project Status
The construction of our first anaerobic digestion (AD) plant is progressing well. Please see our latest project progress report for further information.

How is Biogas Produced?
Anaerobic digestion is a process that produces biogas, a high-energy gas made up of mainly methane (CH4) and carbon dioxide (C02) from the breakdown of organic material in the absence of oxygen. To make it usable in the national gas pipeline, the biogas must undergo a purification process that removes other gases and impurities, turning it into what is called biomethane (a gas composed of 99% methane).

Government-backed Revenue
Plaxton Bridge will qualify for the non-domestic Renewable Heat Incentive (RHI), part of the UK government’s clean energy strategy to stimulate the growth of renewable energy technologies. Under the proposed scheme, the UK government will pay an incentive per cubic metre of biomethane and MWth (megawatt thermal) of heat produced. The incentive will be guaranteed for a period of 20 years.
