Renewables developer Darkish Inexperienced Group has mentioned it plans to be the primary firm within the UK to construct a fleet of anaerobic digestion (AD) crops in city areas. It’s growing as much as 12 AD crops over the following 5 years, on city industrial websites, which collectively may course of over 700,000 tonnes of natural waste per yr and energy as much as 80,000 houses with inexperienced fuel.
Darkish Inexperienced says it has recognized six websites the place it goals to place in planning purposes this yr, and a possible for an additional six past 2025. Its first part of tasks embrace developments at a former industrial web site in Birmingham – at Tyseley Vitality Park, a significant public-private city regeneration scheme – and at quite a lot of manufacturing campuses in Yorkshire. All of the developments will embrace warmth, energy and hydrogen manufacturing.
The proposed AD crops will convert meals waste into inexperienced fuel for houses and enterprise use, serving to native councils meet their Web Zero ambitions, and creating jobs of their building and operation. AD gives an environmental-friendly different to landfill and energy-from-waste incineration, so slicing CO₂ and methane emissions. The Authorities has recognized issues in regards to the emissions from current waste incinerators and introduced on 30 December that it’s tightening restrictions on planning purposes for them.
Darkish Inexperienced’s plans are also a response to the adjustments in meals waste laws that come into impact this yr, with all non-household premises in England required to separate meals waste and organize for its separate assortment. This can imply 4.75m tonnes of meals waste shall be diverted from common waste streams and can have to be processed individually.
Charlie Clay, Chief Govt of Darkish Inexperienced Group mentioned: “Modern, urban anaerobic digestion can be a lynchpin in the energy transition as it offers a multitude of benefits for homes and businesses. From the processing of organic waste, we will produce clean, green and secure energy supplied directly to industry and business locally, and for household use. Our solution is a leading example of the ‘circular economy’.”
As well as, Darkish Inexperienced mentioned its proposals assist the UK’s dedication to decarbonise the fuel grid, as a part of the transfer to Web Zero. Darkish Inexperienced’s city AD tasks additionally deal with a significant difficulty with clear power technology by delivering constant and dependable base load energy 24/7.
Darkish Inexperienced’s tasks “will provide businesses with a green gas option to fuel their operations, whether for transport use, heating or manufacturing”. The current Clear Vitality 2030 report from the Nationwide Vitality Programs Operator (NESO) to the Division for Vitality Safety & Web Zero highlighted inexperienced fuel (biomethane) as “an additional clean dispatchable option in the power sector”. Vitality Minister Miatta Fahnbulleh MP additionally just lately commented that: “Anaerobic digestion and biomethane allows us to reduce our reliance on fossil fuels.”
Whereas the UK is forging forward with renewable, sustainable electrical energy provide, lower than 1% of the fuel consumed by houses and companies is inexperienced fuel.

Darkish Inexperienced’s pipeline of 12 tasks goals to deal with over 700,000 tonnes of waste a yr, offering inexperienced fuel for as much as 80,000 houses and companies, saving the identical quantity of CO₂ as taking round 70,000 automobiles off the highway, with further by-products of sustainable natural fertilizer for farming, parks, allotments and gardens.
Whereas city AD plans exist in Europe – for instance in Frankfurt in Germany and Groningen in The Netherlands – within the UK it has been focussed predominately in agricultural areas or on electrical energy manufacturing.
Charlie Clay added: “Anaerobic digestion and its organic fertiliser by-products allow city waste to be looped back into the growing cycle for the sustainable production of food. Also, we will produce biogenic CO2 which can be used for making food and in the creation of sustainable aviation fuel and other similar fuels.”
Darkish Inexperienced provides that its tasks at Tyseley Vitality Park and in Yorkshire will provide hubs for the analysis and improvement of waste restoration and fuel manufacturing, being networked with industrial companions who’re on the forefront of local weather tech innovation.
