Qualitas Energy inaugurates first UK renewable biomethane facility

September 9, 2025 |

In the UK, Qualitas Energy has inaugurated its first renewable biomethane facility in the United Kingdom: Three Maids, an anaerobic digestion (AD) plant developed through its portfolio company Acorn Bioenergy.

The plant, located at Three Maids Hill, Winchester, has already created 15 jobs and is expected to support up to 50 positions within the wider engineering, rural and infrastructure supply chain. Designed to process 83,600 tonnes of local agricultural wastes, residues, and break crops annually, the site will produce more than 120 GWh of biomethane per year, enough to meet the entire heat demand of more than 9,000 homes.

Qualitas Energy is rapidly expanding its renewable energy footprint in the UK, leveraging its expertise across the full project lifecycle – from acquisition and development to construction and operation. Through Acorn Bioenergy, which is set to become a leading platform for biomethane and green CO in the UK, Qualitas Energy is developing a nationwide network of AD plants that convert agricultural feedstocks into renewable gases. The Three Maids facility is the first of a dozen planned plants across England and Scotland to become operational. Together, they will inject more than 1.5 TWh per year of biomethane into the UK’s national grid via four gas injection hubs.
