Our Biogas 2 project will be built at Melton, near Hull in the UK. Located next to our Energy from Waste (EFW) plant, it will process 61,000 tonnes of organic fines every year producing approximately four million cubic metres of methane per annum. The plant will use “dry AD” technology to process organic fines (the organic element of black bin waste e.g. soiled food packaging) sorted from the municipal solid waste.
The Melton AD plant will produce just under 2.7MWe of gas which will be pumped directly into the gas grid. The plant takes advantage of the non-domestic Renewable Heat Incentive (RHI). The RHI is part of the UK government’s clean energy strategy, designed to stimulate the development and growth of renewable energy technologies. Under the scheme, the UK government will pay an index-linked incentive, guaranteed for a period of 20 years, for the heat and energy produced. Such incentives make the development of biogas plants a stable, long-term investment for developers and investors alike. Waste will be transferred from the adjacent Transwaste waste processing facility for a competitive gate fee providing an additional income stream for the plant.
Planning permission was granted in April 2019 and site clearance works are in progress. Fichtner Consulting Engineers are engaged in the design process along with our technical team, the main contractor and the technology provider. The plant will be operational 24 hours a day, with a constant feed of organic waste moving through the plant.
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).
Melton AD will qualify for the non-domestic Renewable Heat Incentive (RHI), part of the UK government’s Clean Growth Strategy to stimulate the growth of renewable energy technologies. Under the 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.
