Anaerobic Digestion and Bioresources Association (ADBA) has published a new report stating that around 90 plants in the UK are injecting green biomethane into the gas grid, which is double the number during the same time last year.
ADBA’s December 2016 Market Report also explores the growth, developments, and market changes in the anaerobic digestion (AD) industry to date. It reveals that the total number of AD plants in live operation has increased considerably from 424 last year to 540 this year.
This has added to Britain’s capacity to recycle food waste and increased low-carbon baseload electricity, sustainable farming and wastewater treatment, and green gas in the country’s grid.
ADBA's chief executive Charlotte Morton said: “In 2015 and 2016, green gas has gone mainstream, with bio-methane now heating around 170,000 homes in the UK without the householder needing to do anything differently themselves.
“Biomethane to grid is a real success story for the Renewable Heat Incentive and we look forward to the government setting out its plans for the next phase of the support scheme.
“Incentives for renewable electricity, however, are heavily restricted, which is a huge missed opportunity. With the right support, the biogas industry could deliver 250MW of new generation capacity over the next two years, enough to add 10% to our tight winter 2018 capacity margin and bring benefits to farming, recycling, and the economy.”
In addition, AD has been successful in reducing the UK's greenhouse gas emissions by almost 1% per year. In spite of policy uncertainty regarding the future of low-carbon energy support, which according to ADBA might still affect future growth, there has been a significant increase in the number of green gas plants this year.
